What is doxing, and how to prevent your personal data from being exposed on the Internet
The Internet is a space where we share information daily. Social networks, forms, online purchases… Each action leaves a slight digital trace. Most of the time, we are unaware of how much we reveal about ourselves. This is where an increasingly well-known (and feared) concept comes into play: doxing.
What is doxing, and why should you care?
Doxing (abbreviation of dropping dox or 'release documents') refers to the public exposure of a person's data without their consent. We talk about addresses, telephone numbers, workplaces, private photos, emails, real names, and even financial or family information.
These types of attacks, which initially emerged in particular online communities, have spread in recent years and can have serious consequences: from harassment, threats, and identity theft, to the loss of employment or the appearance of legal problems.
Doxing on the Internet is not a simple hacker's game:It is a form of digital violence. And it can affect anyone.
Qondar: a solution that helps you protect your digital privacy
Before continuing, it is worth stopping at our featured tool: Qondar, a solution for personal cyber surveillance.
Qondar has been developed for anyone who wants to maintain control over their information on the network without needing advanced technical knowledge. It works like a Continuous Threat Exposure Management (CTEM) platform. It lets you detect if your data is being shared without permission in forums, leaked databases, social networks, or even the dark web.
Even if you don't know what doxing on the internet is, you too may suffer from an attack. If so, Qondar will tell you before it's too late.
Why does someone decide to dox another person?
There is no single attacker profile, nor a single motivation. Doxing, as this phenomenon is also known, can have many faces:
- Personal revenge: Ex-partners, ex-friends, or work conflicts can lead to malicious leaks.
- Extreme ideology or activism: Some users publish data about opponents to intimidate or silence them in political or social debates.
- Practical jokes or viral challenges: especially among teenagers or in toxic online communities.
- Extortion and blackmail: Once they have your data, some attackers try to obtain money or favors in exchange for not disclosing it.
Whatever the reason, the result is the same: your privacy and security are compromised.
What type of data is typically exposed when doxing?
Although the degree of exposure varies, the most common data that is published or sold in doxing cases are:
- Full name and physical address
- Phone number
- Profiles on social networks
- Personal photos
- Information about the family environment
- Employment or academic data
- Purchase or search history
A simple search in filtered databases (such as those found on the dark web) can be enough to create a detailed profile of a person. That's why prevention is key.
How to avoid being doxed: good practices to protect your privacy
To know how to protect yourself from doxing involves changing certain digital habits.. Here are some practical tips that you can start applying today, now that you understand what doxing is:
1. Check your social networks
- Use strict privacy settings.
- Avoid sharing personal information such as your address or your children's school.
- Do not post photos of documents or screenshots with sensitive data.

2. Use strong and unique passwords
- Don't repeat passwords across multiple services.
- Enable two-step authentication (2FA) whenever possible.
3. Be careful with online forms and contests
- Do you need to give out your phone number to enter that giveaway?
- Use secondary or temporary emails when possible.
4. Avoid heated discussions in public forums
- Many victims of doxing end up being attacked for their opinions.
- Participate respectfully and avoid sharing unnecessary details.
5. Do searches about yourself
- Type your first and last name in search engines to see what appears.
- Use tools like Qondar to get a complete view of your online exposure and receive alerts if anything changes.
What do you do if you have been doxed?
It may finally happen even if you have done everything possible to avoid being doxed. In this case, the most important thing is to act quickly:
- Document everything that has been published (captures, links, etc.).
- Contact the platforms where the information has been disclosed and request immediate withdrawal.
- Report the case to the Police and authorities, especially if there are threats or blackmail.
- Go to your national Data Protection Agency if your rights have been violated.
- Receive psychological support if the emotional impact has been substantial. Digital bullying can seriously affect mental health.
Is there a definitive solution?
The reality is that there is no 100% foolproof barrier. But yes, you can minimize your exposure and protect yourself from doxing to be prepared for any threat.
This is where Continuous Threat Exposure Management (CTEM) solutions, like Qondar, come into play. This tool offers you something that few solutions provide: active and personalized digital identity monitoring.
Knowing when and where your information appears allows you to act before it's too late. What is not controlled on the Internet can get out of hand in seconds.
Now that you know what doxing is, it is not a distant concept exclusive to celebrities or public figures. Anyone can be a victim. And in a society as hyperconnected as the current one, shielding our personal information has become a necessity, not a luxury.
Luckily, there are tools available to everyone to avoid this. If you are looking for an effective way to protect yourself from doxing and keep your digital identity under control, Qondar by Enthec is a solution that can help you sleep more peacefully.
Your privacy is not a simple detail to consider; it is part of your security. Start caring for her today with Qondar.

Due Diligence in cybersecurity: How to protect your company during an audit?
The word 'audit' usually causes some tension in any company. Whether for legal, financial, or technical reasons, any external review necessitates a critical examination of our processes.
And when we discuss cybersecurity audits,the tension escalates. Are we protected? Do we know where our weaknesses are? What if the auditor finds an open door?
This is where cybersecurity due diligence comes into playan essential process to prepare your company for this type of evaluation. Beyond legal compliance, it is about protecting critical assets, reputation, and, above all, the trust of your clients and partners.
What is cybersecurity due diligence?
When a company undergoes a due diligence audit, whether for an investment, a merger, or to comply with regulations, one of the key aspects that is analyzed is the state of its cybersecurity.. Internal policies, incident response protocols, network configurations, and the storage of sensitive data are reviewed, among other relevant aspects.
Due diligence seeks to identify risks before they become problems.. In the digital context, this means detecting web vulnerabilities before an attacker does.
For example, typical examples of due diligence may include reviewing the security of connected devices (IoT), analyzing remote access, protecting personal data, or ensuring the company's visibility on the dark web.
Now, how can an organization prepare so that this review does not become an endless list of failures?
Before the audit: visibility and prevention
This is where tools like Kartosby Enthec play a fundamental role. This is a Continuous Threat Exposure Management (CTEM) solution designed for companies that want to know, in real-time, what attack surface they are presenting to the world.
That is, what information, configurations, or failures are visible from the outside, in the same way that a potential attacker or auditor sees them.
And this is no small thing. During the due diligence process, one of the most common mistakes is relying solely on internal measures or static reports.. However, threats evolve daily, just as a company's digital footprint does.
Kartos enables continuous monitoring, detecting everything from leaked passwords to exposed services, poorly configured repositories, and even vulnerabilities in IoT devices, such as surveillance cameras, sensors, and routers.
What can (and cannot) a due diligence audit detect?
In the same way that a penetration test, or pentesting, occurs,traditional cybersecurity due diligence has a limited scope. Although it allows you to identify technical, regulatory, or process risks at a specific point in time, it does not provide a continuous or dynamic view of the company's actual exposure status.
It's like taking a static photo of a network at a specific moment. However, the threats persist, and the attack surface evolves with each new configuration, vendor, employee, or service that comes online.
This is where Kartos shines.. This tool detects which weaknesses can be seen from outside in real time:
- Leaked credentials in databases or forums.
- Misconfigured utilities or exposed.
- Forgotten subdomains or without protection.
- Expired digital certificates.
- Known vulnerabilities in systems accessible from the Internet.
- Information that is visible in open sources and on the dark web.
But the most important thing is not only what it detects, but what due diligence cannot detect if it is not complemented. Without continuous monitoring, any audit becomes obsolete the moment it is completed.
Therefore, the due diligence process needs to be supplemented with tools like Kartos to cover the remaining risk areas. Only in this way can we speak of a complete vision.
Why do IoT vulnerabilities escape traditional due diligence?
One of the most common blind spots in due diligence audits is the Internet of Things (IoT) devices. Cameras, sensors, printers, and routers are all integral components of a company's digital ecosystem; however, many of them are not properly audited or managed.
And this is a problem. According to data from Kaspersky (2023), attacks on IoT devices grew by 41% in a single year.. Many of them exploited default passwords, outdated firmware, or open ports that had not been checked.
The most worrying thing? These types of errors are not always visible during a traditional due diligence process, especially if they are not integrated into a clear policy or are not part of the official inventory.
With Kartos, these elements are brought into focus, as the tool analyzes what is visible from the outside, just as an attacker or external researcher would do.. This allows critical input vectors to be detected before they generate an incident… or before an auditor flags them as a serious threat.
What does the cybersecurity due diligence process include?
Although it varies depending on the type of audit, a typical process usually includes:
1. Document review
Security policies, contingency plans, internal training, and other relevant measures. Here we analyze whether the company has clear rules and applies them.
2. Technical analysis
Network scans, log reviews, malware detectionpenetration tests, and more. In this phase, fundamental weaknesses are detected.
3. Exposure assessment
This point is key and often ignored. It attempts to analyze what information is visible from the outside, such as external access, open services, and data leaks. Precisely, Kartos' strong point.
4. Risk assessment
With all of the above, a risk map is generated that enables informed decisions to be made, such as reinforcing measures, prioritizing investments, or even pausing operations if the level of exposure is extremely high.

What are the benefits of getting ahead of the audit?
Preparing ahead of time not only reduces stress but also enhances the company's position with investors, partners, or buyers.. Additionally, it allows:
- Anticipate problems before third parties detect them.
- Enhance your security posture without last-minute rushes.
- Increase confidence in strategic business decisions.
And above all, it transmits an image of technological maturity, which in 2025 is more critical than ever.
Enthec: ally during the due diligence process
Enthec not only offers cybersecurity solutions like Kartos (for companies) and Qondar (for individual users), but also provides tranquillity. The possibility of knowing, at any time, how exposed your organization is. To receive alerts before the media does. To anticipate, instead of react.
Because in cybersecurity, information is power, but continuous monitoring is a matter of survival.
If you are preparing an audit or want to assess the visibility of your weaknesses, it's time to talk to Enthec.
Cybersecurity audits are not a luxury, but a necessity. Due diligence should not be seen as a threat, but rather as an opportunity to strengthen our systems, learn from our weaknesses, and demonstrate to the market that we are prepared.
Because, ultimately, it is not just about passing an audit, but about building a safe, solid, and sustainable company.
IoT and cybersecurity: Risks and strategies to protect connected devices
We live in an era where everything is interconnected. From our smart watches to the home thermostat, including surveillance cameras, speakers, locks, and even the refrigerator. This interconnection, known as the Internet of Things (IoT), makes our lives easier in many ways.
Cybersecurity in IoT, is, today more than ever, a real need. The exponential growth in the number of connected devices has led to an increase in vulnerabilities and attacks.
It's not just about protecting personal data; we're also talking about physical security, privacy, business reputation, and even operational continuity in companies that rely on IoT for their processes.
Cybersecurity in IoT is not optional
According to a Kaspersky report, in the first half of 2023, there was a significant increase in threats targeting IoT devices, including DrDoS attacks, DDos, ransomware, and other types of malware that exploit common vulnerabilities such as default passwords and insecure network services.
And that's just the tip of the iceberg. Many devices are not correctly configured, use weak passwords, or continue to run on outdated software.
One of the biggest mistakes is assuming that an IoT device is harmless because it does not store sensitive data. But it only needs to be connected to the same network as other, more critical equipment for it to become a gateway to the system.
What types of vulnerabilities are common in the IoT?
The threats affecting the IoT ecosystem are varied, but many share a familiar pattern: lack of basic protection.. Some examples:
- Default passwords.. Many IoT devices come with factory credentials that users never change.
- Unnecessary open ports.. Access that allows attackers to explore and manipulate the device easily.
- Non-existent or manual updates.. Many manufacturers do not offer automatic updates, leaving their devices vulnerable to known security flaws.
- Unencrypted communication.. Some devices transmit information in plain text, making it easier for third parties to intercept and read the data.
- Poor network segmentation.. Using the same network for IoT devices and personal computers or servers makes it easier for a breach to affect the entire system.
The importance of a global vision: IoT cybersecurity in companies
In the business environment, these vulnerabilities can have a devastating impact. Let's consider a factory that automates processes using sensors, cameras, and interconnected equipment. A single compromised device can paralyze production or leak strategic information.
This is where having advanced surveillance and threat analysis tools, such as Kartos, Enthec's business solution, is crucial.. Kartos enables you to identify vulnerabilities, such as leaked credentials on the dark web, exposed devices, or data leaks related to the company's connected assets.
Kartos provides Continuous Threat Exposure Management (CTEM), offering a real-time, updated, and comprehensive view of the company's exposure level.
Kartos not only detects but prioritizes the most relevant risks for the business and recommends concrete actions to mitigate each threat. This is especially useful for IT and cybersecurity managers, as it allows them to make quick and informed decisions.
Do you want to know your company's level of exposure in real-time? Contact us to discover how Kartos can help you protect your IoT infrastructure from exposed leaks and open breaches.
IoT risks: beyond data
Security in IoT extends far beyond preventing information theft. Some of the IoT risks most relevant include:
- Unauthorized access to security cameras that can be used for spying or blackmail.
- Manipulation of sensors or automated systems, generating interruptions or physical damage.
- Using devices as bots in massive attacks (DDoS) without the user being aware.
What can we do? Strategies to improve cybersecurity in IoT
Basic measures that every user should adopt
- Change default passwords and use strong keys.
- Update the firmware of devices regularly.
- Disable unused features, such as remote administration.
- Separate the networks, creating an exclusive network for IoT devices.
- Review the permissions and access of each team.
Strategies for companies
- Inventory all IoT devices connected to the network.
- Implement cybersecurity solutions and cyber surveillance tools, such as Kartos, which identify exposed devices and leaks in real-time.
- Apply network segmentation policies to isolate vulnerable devices.
- Establish strong access controls and multi-factor authentication.
- Continuously monitor exposure to external threats, without relying solely on periodic audits.
And private users?
We cannot forget that homes are also increasingly complex IoT environments. For them, Enthec has developed Qondar, a customized CTEM solution for individuals.
Qondar enables anyone to verify if their credentials have been compromised, if their devices are publicly exposed, and even, beyond IoT technology, if there is any trace of their digital identity circulating in insecure environments. A handy tool for enhancing privacy and safeguarding against malicious uses of information and emerging technologies, such as IoT.
Prevention is cheaper than disaster
Investing in IoT cybersecurity is not an expense, but a wise investment.. The costs derived from a security breach (reputational damage, business interruptions, legal sanctions...) can far exceed any budget allocated to protection.
Additionally, being one step ahead in risk management allows companies to innovate with confidence, knowing that their digital environment is protected. And that translates into a competitive advantage.
Digital transformation is here to stay, and the Internet of Things (IoT) is a crucial component of this change. However, every new technology comes with its own set of risks. Shielding security in IoT should be a top priority for both companies and individuals.
Solutions like Kartos and Qondar by Enthec stand out in the way we manage those risks. It's not just about protecting devices: it's about protecting everything behind them.

Compliance with CRA regulation: How can you achieve it in your company?
The CRA regulation (Cyber Resilience Act) is one of the terms that is being heard increasingly in the European business environment, especially in IT and security departments. And it's no wonder.
This new legal framework aims to reinforce products' digital security with digital elements marketed in the European Union.
But what does this mean for your business? What practical implications does the CRA regulation have in your daily life? And how can you comply with it without making it an unsustainable burden on your technical teams?
Before getting into the matter, it is worth remembering that, although this type of regulation may seem complex in its initial approach, it also represents an opportunity: to improve your cybersecurity maturity, better protect your digital assets, and gain trust from clients and strategic partners.
This is where Enthec comes into play.Enthec is a company that specializes in cyber surveillance and continuous threat exposure management (CTEM) solutions. Our solution, Kartos, is aimed at companies and allows for proactively identifying, monitoring, and managing external exposure risks.
What is CRA regulation?
The CRA regulation, or cyber resilience regulation, is a legislative proposal of the European Union that seeks to ensure the safety of products with digital components throughout their life cycle.
This horizontal regulation affects all types of devices connected to the internet,from business management software to smart home appliances. The objective is clear: prevent security flaws from becoming entry points for attackers.
This cyber resilience law requires manufacturers, distributors, and importers to comply with a series of security requirements, including:
- Risk assessment before launching the product.
- Active vulnerability management.
- Transparency about security incidents.
- Security updates throughout the life of the product.
According to a report from the European Union Agency for Cybersecurity (ENISA), over 50% of attacks in Europe originate from known vulnerabilities that remain unpatched.
Who is affected by the CRA regulation?
Although it may seem that only technology companies should worry, any organization that markets products with digital elements within the EU is subject to this regulation.
That includes:
- Software manufacturers.
- Companies that integrate digital systems.
- Connected hardware distributors.
- To a lesser extent, business users obliged to demonstrate good practices in the digital supply chain.
In this sense, if your company integrates third-party software In this sense, if your company integrates third-party software into its processes, you should check that these suppliers are aligned with the standards of the CRA regulation. If they fail, the problem can also reach your business. Through our third-party license, you will be able to manage these types of relevant issues.

How can compliance with the CRA regulation be achieved?
Compliance with the CRA regulation is not a one-day task but a continuous process that requires planning, resources, and strategic vision. Here we leave you some keys to address it successfully:
1. Assess your exposure to digital threats
Before implementing any measures, you should know your organization's attack surface,. what digital assets are exposed, what the weakest points are, and what services are available on the Internet without need.
With tools like Kartos, you can have a clear and up-to-date view of your exposure and make decisions based on concrete data.
2. Classify risks and prioritize actions
Not all risks are the same or have the same impact. An effective compliance policy must include a classification system by criticality levels. This allows you to prioritize correcting those vulnerabilities that pose the greatest danger.
3. Implement a CTEM strategy
One of the best ways to comply with the CRA regulation is to adopt a Continuous Threat Exposure Management model (CTEM). This strategy is based on:
- Constantly identify new threats
- Validate the effectiveness of your security controls.
- Automate detection and response processes.
Through Kartos, we offer a CTEM-based approach that perfectly fits this need.
4. Train your team
Having the best tools is not much use if your team is unprepared. Continuous cybersecurity training is essential so that all members of your organization understand their role in digital protection.
Furthermore, the cyber resilience culture should not be limited to the IT area: it must be present in the DNA of the entire company.
5. Document and audit
The cyber resilience regulation requires transparency. Therefore, it is essential to document security actions,implemented controls, and recorded incidents. This will ensure you have all the necessary support if an audit occurs or a decision must be justified.
Benefits of complying with the CRA regulation
Although it may seem like just another obligation, the truth is that compliance with the CRA regulation can become a competitive advantage:
- Improves your brand reputation.
- Increases the confidence of customers and partners.
- Reduces the risk of sanctions and economic losses.

The importance of cloud security in protecting your data
Personal and professional data has become one of the most valuable assets. We are not just talking about documents, photos, or emails, but sensitive information, contracts, bank details, business plans, and strategies. In most cases, all of this is stored and managed in the cloud.
However, this convenience has its counterpart: cloud security risks. They are not a simple possibility but a reality affecting companies and individuals. Protecting our data against digital threats is an urgent need, not a technological luxury.
Before getting into the matter, you should know Kartos, our solution for companies that want to maintain control over their cybersecurity. Kartos is a Continuous Threat Exposure Management (CTEM) solution that constantly monitors an organization's digital environment and detects vulnerabilities before they become a real problem.
What exactly is cloud security?
When we talk about cloud security, we refer to the set of technologies, policies, controls, and procedures that protect systems, data, and infrastructure hosted on cloud platforms.
That is, it is not just about using strong passwords but about ensuring that the cloud service provider, configuration, and users act safely and consciously.
Here, we have everything from encryption systems to access control practices, threat detection, and incident recovery plans.
How does cloud security work?
Cloud security operates at several levels:
- Infrastructure layer: where the hardware and physical servers on which the cloud resides are protected.
- Network layer: responsible for monitoring data traffic and preventing unauthorized access.
- Application layer: This guarantees that the applications do not have flaws that allow attacks.
- Data layer: where encryption, authentication, and backup tools are implemented.
In addition, there are specialized tools that go beyond static protection, as is the case with our solutions, which work under an active cyber surveillance model. This means that they not only protect but also constantly monitor and evaluate the level of exposure to digital risks.
Why should we take cloud security risks seriously?
Cyber attacks are a reality. According to an IBM study published in 2023, the average cost of a cloud security breach is $4.35 million.. And it's not just large companies that are frequent targets: SMEs and individual users are also frequent targets precisely because they tend to have laxer security measures.
Some of the top cloud security risks include:
1. Unauthorized access
Poor permission management or weak passwords can give cybercriminals access. This is especially serious if the data involved is personal, financial, or confidential.
2. Data loss or leak
Cloud systems can be misconfigured, exposing files. Sometimes, user data has been published inadvertently due to human error or technical oversights.
3. Ransomware attacks
In these attacks, criminals encrypt files stored in the cloud and demand a ransom to release them. Staining that data may be impossible without a good backup and discovery strategy.
4. Misuse of resources
Sometimes, attackers do not seek to steal data but instead use the infrastructure to mine cryptocurrencies or launch other attacks from our account, thus compromising the reputation and resources of the organization.
How to protect yourself: keys to a good cloud security strategy
It is not enough to have good faith or trust that “it won't happen to me.” Prevention is the only effective barrier against threats. Here are some basic recommendations:
Choose trusted suppliers
Not all cloud platforms offer the same level of security. Ensure the supplier complies with regulations such as ISO 27001 o GDPRand has clear incident protocols. A third-party risk assessment, like the one allowed by Kartos, is key to protecting your value chain and preventing someone else's weakness from compromising you.
Monitor your exposure
This is where a solution like Kartos is beneficial. Through active external attack surface (EASM) management,Kartos detects exposed assets, vulnerable configurations, or spoofed domains. This allows anticipation phishing or brand impersonation campaigns, which are common in targeted attacks.
Use strong passwords and multi-factor authentication
It seems obvious, but even today, many credential leaks start with a weak or reused password. If you can, enable two-step authentication on all services. Kartos can detect when your credentials are exposed on dark web forums or markets.
Make regular backups
If your information disappears or is hijacked by ransomware, the best way to protect yourself is to have an up-to-date, secure copy. Although Kartos does not replace backup, its constant monitoring helps detect anomalous activity before attacks, which can give you time to act.
Educate your team
Many times, the weakest link in the security chain is the human. One click on a fake message on social networks or a cloned website can be enough to land you in a phishing, fraud, or identity theft campaign.
Enthec's role in your digital security
In this scenario, Enthec is not just a technology solutions provider. It is a strategic ally in cyber surveillance and active protection. Its CTEM approach allows continuous monitoring of the status of your cybersecurity, offering quick and effective responses.
Through Kartos, designed for companies, you can evaluate each exposed vulnerable point of your digital infrastructure. This tool helps you make informed decisions and act before a problem exists.
Cloud security is your responsibility
It is easy to think of the cloud as an intangible and harmless space. But the truth is that, like any place where value is stored, it has dangers. Cloud security is not optional but an investment in peace of mind, reputation, and continuity.
Solutions like those offered by Enthec, with its proactive approach tailored to businesses and individual users, put you several steps ahead of cybercriminals.
Don't wait for something to fail to act. Start protecting your data with Enthec today.
NIS 2: How does it affect companies, and what measures must be taken to comply with the regulations?
In an environment where cybersecurity has become critical for business survival, the entry into force of the NIS 2 Directive marks a before and after for hundreds of organizations in Europe.
This is not a recommendation or a simple guide to best practices: NIS 2 is mandatory and requires companies to protect their systems, data, and services against increasingly complex threats.
But what exactly does this directive imply? How does it affect companies in Spain, and which sectors must comply with it? Above all, how can an organization adapt without being overwhelmed by technical complexity?
This article explains everything clearly and shows how tools like Kartos by Enthec can help you take that step safely and effectively.
What is the NIS 2 Directive?
The NIS 2 Directive (Network and Information Security) is the evolution of the first NIS directive, approved in 2016. It was created to improve the resilience of essential services to cyberattacks. resilience of essential services to cyberattacks.
However, the first version was reduced due to the evolving threat landscape. That's why the European Union published the new NIS 2 Directive in January 2023, significantly expanding its scope and requirements.
What changes with NIS 2?
- The number of affected sectors is expanded.
- Security and notification obligations are tightened.
- Penalties for non-compliance are increased.
- Cybersecurity governance and oversight in member countries are strengthened.
NIS 2 regulates and demands active company responsibility, incorporating continuous surveillance, prevention, and threat response measures.
Which companies are affected by NIS 2?
One of the key points of this regulation is its expansion of the scope of application.. It is no longer limited to large critical infrastructures such as electricity, transport, or health. No,w it also includes medium and large companies in sectors such as:
- Information and communication technologies (ICT)
- Chemical and food manufacturing
- Water, waste, and digital services management
- Cloud service providers, data centers, DNS, and domain registries
According to INCIBE estimates, more than 12,000 entities in Spain could be affected by the NIS 2 regulation.. Many of them, especially tech SMEs, have not yet started to prepare.
What does NIS 2 require of companies?
Complying with NIS 2 is not just a matter of software or firewalls;it involves a comprehensive approach that affects the organization at multiple levels.
Among the main requirements, the following stand out:
Technical and organisational measures
Enterprises must implement appropriate security controls, from network segmentation and vulnerability management to access policies or data encryption.
Ongoing risk assessments
Regulations require regular analyses and assessments of risks associated with the security of networks and systems.
Obligation to report incidents
In the event of a significant incident, the company must inform the competent authorities within 24 hours, which requires having effective detection and response systems.
Governance and accountability
Senior management must be actively involved in the cybersecurity strategy. Responsibility cannot be delegated solely to technical teams.
Sanctioning regime
NIS 2 introduces penalties that can reach up to €10 million or 2% of global annual turnover, making compliance a strategic necessity.

Common Types of Cyberattacks - Part II.
Computer security is a fundamental pillar for companies and individuals. Technological advances have facilitated the digitization of many processes but have also opened the door to new risks.
Knowing the most common types of cyberattacks is key to preventing them and minimizing their consequences. This is not only about protecting personal data but also about preventing companies and institutions from suffering attacks that could affect their operations and reputation.
Advanced surveillance and security management tools are essential to dealing with these threats. In this sense, Kartos offers a solution specialized in Continuous Threat Exposure Management (CTEM).
We monitor and analyze vulnerabilities, detecting information leaks and security breaches before cybercriminals can exploit them.
What is a cyberattack, and how many types are there?
We call a cyberattack any type of offensive maneuver used by individuals or entire organizations that targets computer systems, infrastructures, computer networks, and/or personal computer devices. These attacks attempt to hack into a system through one or more digital acts, usually originating from an anonymous source, to steal, alter, or destroy a specific target.
There are different types of cyberattacks, which can be classified according to their method of attack or the purpose they pursue. Below, we explain the most frequent and dangerous ones.
Main types of cyberattacks
Ransomware
This attack has become one of the most devastating threats in recent years. Ransomware encrypts files on a device or an entire network and demands payment to restore access.
Victims often receive threatening messages stating that if they do not pay the ransom within a specific time, they will lose their data forever. However, paying does not guarantee the recovery of the information and, in addition, finances the attackers to continue operating.
Phishing
Malware
Malware is any type of software that intentionally performs malicious actions on a system without the user's knowledge. Viruses, worms, and Trojan horses are different types of malware.
Within malware, we find several categories:
- Virus. A computer virus is a small script of code that, when executed, replicates itself by modifying other computer programs, which are called hosts, and inserting its own code to alter a computer's operation. Of course, since this is a type of malware, all of this is done without the user's permission or knowledge.
- Worms. A computer worm is a standalone malware program that replicates itself to spread to other computers. This differs from a virus because the virus needs a host program, but the worm does not. A worm often uses a computer network to spread, relying on security flaws in the target computer to gain access to it. Once there, it will try to scan and infect other computers.
- Trojan Horse. A Trojan horse virus is a type of malware that is downloaded onto a computer disguised as a legitimate program. It is usually hidden as an attachment in an email or a free download file and then transferred to the user's device. Once downloaded, the malicious code will execute the task the attacker designed it to do, such as spying on users' online activity or stealing sensitive data.
Malware can compromise everything from individual computers to large business networks, causing financial losses and operational problems.
Phishing
Phishing is a method of social engineering in which attackers impersonate legitimate entities (banks, businesses, or online services) to trick victims into obtaining sensitive information.
Phishing emails often include links to fake web pages that mimic the real thing. When the victim enters their data, cybercriminals steal it and use it to access bank accounts, emails, or corporate networks.
Phishing attacks have evolved, and there are now more sophisticated variants, such as spear phishing, which is aimed at specific targets within a company, and whaling, which is focused on managers and senior managers.
If you want to learn more about this cyberattack, access our post→ Phishing: what it is and how many types there are.
Denial-of-service (DDoS) attacks
Distributed denial-of-service (DDoS) attacks seek to overload a website or online service's servers by sending a massive volume of fake traffic. As a result, the servers stop working correctly, preventing access to legitimate users.
These attacks can be used to extort money from companies, causing economic losses and damaging the reputation of the affected company.
Spyware
Spyware is spyware installed on a device without the user's knowledge. It aims to collect private information, such as browsing habits, passwords, or banking details.
Some spyware records everything the user types on their computer, making it easier to steal credentials. Others take screenshots or activate cameras and microphones without authorization.
Botnet
Botnets are networks of infected devices that cybercriminals use to carry out massive attacks. These devices, called bots, can be personal computers, servers, or IoT (Internet of Things) devices, such as security cameras or smart appliances.
Botnets allow attackers to automate spamming, distribute malware, conduct DDoS attacks, or mine cryptocurrencies without the knowledge of the owners of the infected devices.
Man-in-the-Middle (MitM)
In this attack, the cybercriminal intercepts communication between two parties to spy, manipulate, or steal information.
These attacks often occur on insecure public Wi-Fi networks, where attackers can capture sensitive data, such as bank account access credentials or emails.
Companies should have an advanced cyber surveillance solution that allows detecting and mitigating threats before they materialize.

Factors that facilitate BEC attacks on senior managers and solutions to mitigate them
Businesses are increasingly exposed to sophisticated cyberattacks that seek to exploit their vulnerabilities. BEC (Business Email Compromise) attacks have become one of the biggest threats to organizations of all sizes.
The main format of this type of fraud is social engineering: cybercriminals impersonate a senior manager to deceive employees and suppliers, achieving fraudulent money transfers or the theft of critical information.
The problem is that these attacks depend not on technical vulnerabilities but human errors and insecure processes.The risk is multiplied if senior executives are targeted: their access to privileged information and decision-making capacity make them perfect targets.
How can companies protect themselves? The answer lies in continuous management of exposure to threats. This is where solutions such as Kartos by Enthec come into play: a cyber-surveillance tool that allows companies to identify risks before they become serious incidents. But before discussing solutions, let's look at why BEC-type attacks are so successful among senior managers.
Why are senior managers the preferred target in BEC attacks?
Cybercriminals seek to maximize their profitability with as little effort as possible. Senior managers offer the perfect combination of authority, access to sensitive data, and a high volume of financial communications.
Here are some key reasons why BEC-type attacks are so successful in this profile:
1. High level of trust in your communications
Managers are used to having great responsibility and often must make quick decisions.For this reason, they may not question every email they receive, especially if it comes from a regular contact. Attackers use this trust to sneak into the daily routine without raising suspicion.
2. Frequent use of personal devices
Many executives use their mobile phones or tablets to access corporate email without the same security measures as on a company computer. This facilitates unauthorized access and spoofing.
3. High workload and urgency in decisions
Senior managers are often overloaded with tasks and under pressure to respond quickly. Cybercriminals use tactics such as a "sense of urgency" to get users to act without verifying the authenticity of an email or payment request.
4. Public profiles on the internet and social networks
Information about a CEO or CFO is usually available online: interviews, LinkedIn posts, events in which they participate, etc. This helps attackers build extremely credible fake emails, using language and tone similar to the manager's.
5. Lack of specific cybersecurity training
Unlike other employees, executives rarely receive ongoing training in digital security.Their position in the company often results in them being excluded from these processes, making them a weak link in the security chain.
How to Mitigate BEC Attacks on Senior Managers
Prevention is the key to avoiding falling for a BEC attack. Companies must combine awareness, technology, and security protocols to reduce exposure to these threats.
Here are some fundamental measures:
1. Implement a Continuous Threat Exposure Management (CTEM) solution
CTEM tools allow real-time analysis of threats targeting the company and its managers. For example, at Kartos, we constantly monitor the company's level of exposure, detecting impersonation attempts or data leaks that could facilitate a BEC attack.
2. Strict verification of sensitive transactions
Businesses must establish two-factor authentication to authorize payments or changes to bank accounts. An email is not enough; It must be confirmed by phone or through a secure system.
3. Protecting the digital identity of senior managers
It is crucial to minimize public information about them on the internet and social networks and to locate sensitive personal information that may be exposed. In addition, they must use corporate email addresses with authentication protocols such as DMARC, SPF, and DKIM to prevent spoofing.
4. Continuous training and attack simulations
Managers should participate in phishing simulations and receive specific cybersecurity training. This will help them identify fraudulent emails and react appropriately to attack attempts.
