Introduction

Ebolas Stealer is a new hybrid malware combining infostealer, RAT, and ransomware capabilities into a single package sold for just $15/week.

The author claims it's fully undetectable (0/73 on VirusTotal), though such claims should be treated with caution. What makes Ebolas concerning is its low barrier to entry and comprehensive feature set.

Ebolas infections have already been observed in the wild. Reddit users have reported encrypted files and ransom notes:

Discovery

I first encountered Ebolas on GitHub, where threat actors were distributing it as a fake Roblox cheat impersonating Exunys, a legitimate cheat developer. The malicious executable has since been taken down.
