Trojan

A Trojan, or Trojan horse, is a type of malware that appears to be a legitimate program but is actually designed to harm, steal, or disrupt a computer system.

Trojans are often disguised as harmless files or software programs, such as games or productivity tools, and are usually distributed through email attachments, file-sharing networks, or malicious websites.

In crypto, a trojan can steal cryptocurrency by making undetectable duplicates of the victim’s private and public key store.
