Background for this topic.
A Trojan is malware that masquerades as legitimate, useful, or necessary software so a user or process runs it. “Trojan” describes a delivery or deception technique rather than one malware family; capabilities vary by sample and may include credential theft, surveillance, file manipulation, or remote access. Unlike self-propagating malware, a Trojan generally depends on being installed or executed through some other means.
Security analysis should identify the specific family and executable behavior rather than treating every Trojan as equivalent. Material concerns include untrusted software and tampered installers, execution under excessive privileges, and unauthorized persistence or access to sensitive data. Defenses include using trusted software sources and code-signature or application-control checks, limiting user privileges, monitoring endpoint process and network activity, and isolating suspected hosts. After detection, preserve relevant evidence, remove persistence, assess credential exposure, and investigate other affected systems before returning the device to normal use.
