Trojan malware, so named after the tricking wooden horse of Greek mythology, is a serious threat to individuals and computer systems everywhere. Unlike other forms of malware, trojans impersonate trustworthy programmes or files to deceive unwary users into downloading them. Trojans have the ability to carry out a variety of destructive tasks after they have gained access to a system, including stealing confidential data, allowing hackers unauthorised access, or even erasing data. Antivirus software frequently misses them since they frequently run covertly in the background. Users should take caution when downloading files or clicking on dubious links, update their security software frequently, and maintain strict firewall settings to prevent unauthorised access in order to defend themselves from trojan attacks.
Example
Mark downloads a seemingly harmless software from an unofficial website. Unbeknownst to him, the software contains a Trojan horse malware. Once installed, the Trojan quietly establishes a backdoor into Mark's computer, giving remote access to an attacker. The attacker gains control over the system, stealing sensitive information, monitoring activities, and potentially using it for malicious purposes.
