Infection Vectors
Email Attachments
Email attachments are a well-known infection vector, frequently used by malicious actors to spread malware. The main characteristic of this method is its reliance on user trust. Attackers often disguise harmful files as seemingly innocuous, attached documents. This is conducive for the overall goal of spreading malware, as users can easily overlook possible threats within an attachment. Such emails often mimic legitimate correspondence, which further encourages users to click on the attachment without skepticism. The underlying danger lies in believing that unsolicited or unexpected attachments are harmless, which may not be the case.
Malicious Links
Malicious links represent another notable infection vector. They can be found in emails, social media posts, or websites. The critical aspect of this method is how it exploits users’ impulses to click on enticing offers or intriguing headlines. Many attackers utilize URL shorteners, making the original address obscure and difficult to examine. Malicious links often redirect users to websites laden with malware or phishing sites that aim to capture sensitive information. The simplicity of this vector makes it a detrimental choice for cybersecurity, as users can fall prey without recognizing the underlying threat.
Exploit Kits
Exploit kits are sophisticated tools that automate the process of exploiting vulnerabilities on user systems. The key characteristic of these tools is their ability to target unpatched software defects. Many kits provide a user-friendly interface, allowing even lesser-skilled criminals to engage in attacks. The unique advantage of exploit kits is that they often run a series of exploits simultaneously, significantly increasing the chance of successful infection. Threat actors usually sell such kits on dark web forums, making them accessible. However, being reliant on such structured tools can create dependency issues for criminals, particularly in detecting and modifying new security measures.
Removable Media
Removable media, such as USB drives, provide a physical vector for malware distribution. The important characteristic here is the manual nature of their operation. Users often connect USB drives from unknown devices, allowing malicious software to install on their systems instantly.
