What is Trojan in Cybersecurity?
Malware disguised as legitimate software that tricks users into installing it. Unlike viruses and worms, trojans do not self-replicate. They rely on social engineering to spread. Once installed, trojans can steal data, install backdoors, log keystrokes, or give attackers remote control of the system.
Why Trojan Matters for Your Cybersecurity Career
Trojans are one of the most common malware types that SOC analysts encounter in cybersecurity operations. Incident responders analyze trojan behavior to determine what data was stolen. Security engineers deploy application whitelisting and code signing to prevent trojan execution. Malware analysts reverse-engineer trojans to build detection rules for the entire organization.
