Definition ∞ A Remote Access Trojan, or RAT, is a type of malicious software that grants an unauthorized attacker remote control over a compromised computer system. Once installed, a RAT allows the attacker to perform various actions, including accessing files, monitoring user activity, capturing screenshots, recording keystrokes, and deploying additional malware. It often masquerades as legitimate software to deceive users into installation. RATs are powerful tools for surveillance and data theft.
Context ∞ Remote Access Trojans pose a substantial threat to individuals and organizations involved with digital assets, as they can be used to steal cryptocurrency wallet credentials or directly control compromised systems. News reports frequently highlight RAT campaigns targeting crypto users, often distributed through phishing emails or malicious downloads. Effective endpoint security and user awareness are critical defenses against these pervasive threats. Detecting and removing RATs requires specialized cybersecurity tools.
