Analysis Summary

WSHRAT, also known as “Windows Script Host Remote Administration Tool,” is a type of malware that allows a hacker to remotely access and control a victim’s computer through the use of malicious scripts, typically written in JavaScript or VBScript. This malware is typically spread through phishing emails, social engineering tactics, or through the use of exploit kits on compromised websites. Once a victim’s computer is infected with WSHRAT, threat actors can use it to steal sensitive information, install additional malware, or use the victim’s machine as part of a botnet for various malicious activities. To protect against WSHRAT, it is recommended to keep your computer updated with the latest security patches, use anti-virus software, and be cautious when clicking on links or opening attachments from unknown sources.
