A Remote Access Trojan disguises itself as legitimate software but, once executed, opens a backdoor on the infected system. Unlike viruses that corrupt files, RATs prioritize stealth and persistence. Features often include keylogging, webcam activation, file exfiltration, and password harvesting. The term “cypher” in underground contexts typically refers to a crypted or obfuscated version of a known RAT (e.g., NanoCore, Quasar, or DarkComet) to evade antivirus detection. Therefore, a “cypher rat download” is not a distinct malware family but a category of weaponized remote administration tools.
