Ebolas Stealer: A New Hybrid Threat in 2025

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.

Important: These anti-analysis claims are unverified. Threat actors often exaggerate capabilities to deter analysis.

Recommendations

Tip: Proactive defense significantly reduces risk from hybrid threats like Ebolas.

Deploy EDR solutions with behavioral detection
Enable MFA on all accounts, especially crypto wallets and Discord
Maintain offline backups to mitigate ransomware
Monitor for suspicious persistence mechanisms
Train users on social engineering and suspicious files
Implement network segmentation

Conclusion

Ebolas Stealer represents the concerning trend of hybrid malware combining infostealer, RAT, and ransomware capabilities at an accessible $15/week price point. Its comprehensive feature set lowers the barrier to entry for threat actors.

While some advertised features remain unverified, the threat highlights the ongoing need for robust security measures and continuous monitoring of emerging malware trends.
