DarkComet RAT frequently leveraged known vulnerabilities in software applications and operating systems. Outdated software, particularly plugins and browser extensions, served as prime targets. Exploiting these vulnerabilities often involved drive-by downloads, where a user simply visits a compromised website, triggering the malware’s automatic download and execution. Another common approach involved exploiting vulnerabilities in email clients, allowing the RAT to be installed directly upon opening a malicious email.

Examples of Malicious Attachments and Links

Malicious attachments frequently mimicked legitimate file types, such as Word documents (.doc, .docx), Excel spreadsheets (.xls, .xlsx), or PDF files (.pdf). These files often contained macros that, when enabled, executed the DarkComet RAT payload. Malicious links frequently led to compromised websites hosting the RAT installer or to phishing pages designed to steal user credentials, which could then be used to further compromise the system. A seemingly innocuous email attachment labeled “Invoice.doc” could, in reality, contain a macro that silently installs DarkComet RAT. Similarly, a shortened URL disguised as a legitimate link could lead to a website that downloads the malware without the user’s knowledge.

Hypothetical DarkComet RAT Infection Scenario

Imagine Sarah, a busy office worker, receives an email seemingly from her company’s IT department. The email urges her to update her security software by clicking a provided link. The link leads to a website hosting a disguised DarkComet RAT installer. Sarah, trusting the email’s origin, clicks the link and unwittingly downloads and installs the malware. The RAT silently connects to a command-and-control server, giving the attacker complete access to her computer, including her files, browsing history, and potentially even her company’s network. The attacker could then use this access to steal sensitive data, monitor her activity, or even deploy further malware.
