A Trojan horse is a malicious computer program masquerading as a useful or otherwise non-malicious, legitimate piece of software. Generally spread via social engineering and web attacks, Trojan horses often install a backdoor for remote access and unauthorized access of the infected machine.
An attacker can perform various criminal tasks, including, but not limited to, “zombifying” the machine within a botnet or DDoS attack, data theft, downloading or installing additional malware, file modification or deletion, keylogging, monitoring the user’s screen, crashing the computer and anonymous internet viewing.
