Cybercriminals often use social engineering techniques to trick users into installing RATs unknowingly. This can be through convincing phishing emails, deceptive file attachments, or malicious links.
2. Exploiting Software Vulnerabilities
RATs can exploit vulnerabilities in software, such as operating systems or popular applications, to gain unauthorized access. These vulnerabilities are often patched by software developers, but users who fail to update their software remain at risk.
3. Drive-by Downloads
RATs can be silently downloaded and installed without the user’s knowledge while visiting compromised or malicious websites. This method is known as a drive-by downloadMalvertising: Malicious online advertising that contains mal... and takes advantage of security vulnerabilities in web browsers and plugins.
Capabilities of Remote Access Trojans
RATs possess a wide range of capabilities that allow attackers to perform various malicious activities:
1. Remote Control
RATs grant cybercriminals full or partial control over an infected system, enabling them to execute commands, manipulate files, browse directories, and perform other actions remotely.
2. Keylogging
Many RATs have keylogging capabilities, allowing attackers to record keystrokes on the infected system. This technique enables the theft of sensitive information like login credentialsIncognito Mode: A privacy setting in web browsers that preve... and credit card details.
