A Trojan horse in cybersecurity is a type of malware that disguises itself as legitimate or harmless software to deceive users into installing it on their devices. Once installed, the Trojan can execute a range of malicious activities, such as stealing sensitive data, providing remote access to attackers, monitoring user activity, or damaging files.
Key Characteristics
• Disguised as Legitimate Software: Trojans are typically embedded in what appears to be a useful or desirable program, such as games, tools, or even software updates.
• Requires User Action: Unlike viruses or worms, Trojans do not self-replicate or spread automatically. They rely on users to download and execute them, often through social engineering tactics like phishing emails or fake downloads.
• Hidden Malicious Function: While the program may perform its advertised function, it also carries out hidden, unauthorized actions that benefit the attacker.
