Trojan (Trojan horse)

Probably one of the most notorious terms in cyber security, a Trojan Horse is a type of malware that acts according to the Greek legend: it camouflages itself as a legitimate file or program to trick unsuspecting users into installing it on their PCs. Upon doing this, users will unknowingly give unauthorized, remote access to the cyber attackers who created and run the Trojan. Trojans can be used to spy on a user’s activity (web browsing, computer activity, etc.), to collect and harvest sensitive data, to delete files, to download more malware onto the PC and more.
