Kral Stealer: A Trojan Horse Malware Threat

Trojan horse malware, commonly referred to as “Trojans,” is a type of malicious software that disguises itself as a legitimate application or file. Unlike traditional viruses, Trojans do not replicate themselves; instead, they rely on tricking users into executing them. The name “Trojan horse” derives from the ancient Greek story of the wooden horse that concealed soldiers, symbolizing how this malware infiltrates systems under the guise of something harmless.

The primary purpose of a Trojan is to exploit the trust of the user, enabling cybercriminals to gain unauthorized access to sensitive information, control over systems, or deploy additional malicious software. Trojans can infiltrate systems in various ways, such as through infected email attachments, downloads from untrustworthy sources, or malicious links embedded in websites.
