Understanding and Combatting Trojan Horse Malware: A Focus on TrojanWin32.Leonem

Trojan horse malware, commonly referred to as “Trojans,” represents a broad category of malicious software designed to deceive users by masquerading as legitimate programs or files. Unlike viruses or worms, Trojans do not replicate themselves or spread automatically. Instead, they rely on tricking users into installing them, often by disguising as harmless or even beneficial software. The primary aim of Trojans is to gain unauthorized access to systems and data, leading to a variety of malicious activities.

The name “Trojan horse” is derived from the famous Greek myth where Greek soldiers hid inside a giant wooden horse to infiltrate the city of Troy. Similarly, Trojan malware hides its true intent behind a façade of legitimacy, tricking users into executing it.
