When discussing cybersecurity, we often imagine exaggerated and obvious attacks: viruses that lock your computer, malicious emails demanding ransoms, or fake websites trying to steal your passwords. However, <\/span>other types of threats are much more silent, but equally dangerous:<\/b> the<\/span> passive attacks in cybersecurity<\/b>.<\/span><\/p>\n These attacks sneak in, watch, and wait. And that’s precisely why they’re so difficult to detect. In this article, we’ll unravel what they are, how they work, and, most importantly, <\/span>what you can do to protect yourself<\/b>, whether you are a company or browsing as a private user.<\/span><\/p>\n <\/p>\n In cybersecurity, a passive attack is one in which<\/span> the attacker does not directly interfere with the system’s operation<\/b>but rather simply spies, gathers information, or monitors network traffic without detection. Unlike active attacks, which seek to modify, damage, or control a system, passive attacks act as invisible observers. <\/span><\/p>\n Some typical examples of this type of threat include:<\/span><\/p>\n These attacks may seem less aggressive, but<\/span> the information they collect can later be used for targeted attacks, blackmail, or impersonation.<\/b>. In addition, many cybercriminals use this data as raw material to sell on the dark web.<\/span><\/p>\n <\/p>\n The main problem with passive cybersecurity attacks is that they<\/span> go unnoticed for long periods.<\/b>. They don’t generate any prominent warnings, and in many cases, the victim won’t even know they’ve been spied on.<\/span><\/p>\n This allows the attacker to:<\/span><\/p>\n That is to say<\/span>, a Passive attack is the first silent step before a more decisive blow<\/b>.<\/span><\/p>\n The term passive cybersecurity can be confusing. It sometimes refers to measures that don’t act directly on a threat but merely observe or record it. However, when discussing <\/span>in cybersecurity, passive tracking<\/b> refers to monitoring a malicious actor’s actions without directly intervening in the systems.<\/span><\/p>\n We must not confuse legitimate surveillance with malicious spying.<\/b> Today, many platforms monitor user behavior to offer personalized services. But when this monitoring is carried out without consent, for opaque purposes, or by external actors, it goes from legitimate to dangerous. <\/span><\/p>\n <\/p>\n <\/p>\n Detecting a passive attack can be tricky,<\/b>but it’s not impossible. Some signs can help you identify that something isn’t right: <\/span><\/p>\n If you notice a<\/span> strange use of bandwidth<\/b>, suspicious connections, or unexpected encrypted traffic, it may be a sign that someone is listening.<\/span><\/p>\n If you start receiving very personalized <\/span>phishing campaigns<\/span>,<\/a> messages with details that should<\/span> only be known by legitimate sources, or targeted attacks,<\/b> someone may have been collecting information before without realizing it.<\/span><\/p>\n Good security systems don’t just act against active attacks. Some <\/span>advanced threat management systems,<\/b> like the ones we offer from<\/span> Enthec,<\/span><\/a> allow you to identify suspicious patterns even in quiet environments.<\/span><\/p>\n <\/p>\n In a world where threats don’t always make noise,<\/span> prevention becomes your best ally,<\/b>. and this is where a key concept comes in: Continuous Threat Exposure Management (CTEM).<\/span><\/p>\n This approach is not only based on responding to attacks when they occur but also on <\/span>constantly monitoring what information is being exposed without your knowledge.<\/b>. Because others may be seeing your data even if you don’t.<\/span><\/p>\nWhat is a passive attack in cybersecurity?<\/b><\/h2>\n
