In early 2025, security researchers uncovered a new malware family named Webrat. Initially, the Trojan targeted regular users by disguising itself as cheats for popular games like Rust, Counter-Strike, and Roblox, or as cracked software. In September, the attackers decided to widen their net: alongside gamers and users of pirated software, they are now targeting inexperienced professionals and students in the information security field.

## WebRAT malware spread via fake vulnerability exploits on GitHub
## Bill Toulas
The WebRAT malware is now being distributed through GitHub repositories that claim to host proof-of-concept exploits for recently disclosed vulnerabilities.
Previously spread through pirated software and cheats for games like Roblox, Counter Strike, and Rust, WebRAT is a backdoor with info-stealing capabilities that emerged at the beginning of the year.
According to a report from Solar 4RAYS in May, WebRAT can steal credentials for Steam, Discord, and Telegram accounts, as well as cryptocurrency wallet data. It can also spy on victims through webcams and capture screenshots.
Since at least September, the operators started to deliver the malware through carefully crafted repositories claiming to provide a
