AWS Under Siege: How Hackers Turn Cloud Into Crypto Cash

Hackers have discovered a novel method to monetize AWS services by infiltrating accounts using stolen login credentials. Once inside, they swiftly establish crypto mining operations, often completing the setup within 10 minutes.

Stealth Tactics

The attackers employ sophisticated techniques to remain undetected:

• System Reconnaissance: They meticulously assess the system to determine their capabilities.
• Trace-Free Testing: They probe their access without leaving any detectable traces.
• Role Creation: They establish new roles and permissions to expand their control over the system.

Notable Trick: "disableApiTermination"

This tactic prevents account owners from terminating the hackers' operations, complicating efforts to halt their activities. This method was previously demonstrated by a security researcher last year.

Mining Operations

• Special Image Usage: The hackers utilized a specific image to run their crypto mining software, which has since been removed.
• Automated Scaling: They implemented systems to automatically escalate their computing power, thereby increasing their mining efficiency.

Protective Measures for AWS Users

To safeguard against such attacks, AWS users are advised to:

• Use Strong Passwords: Ensure passwords are complex and difficult to guess.
• Enable Two-Factor Authentication: Add an extra layer of security to the login process.
• Implement Least Privilege: Limit access rights to the minimum necessary for each user.
• Monitor Systems: Regularly check for any unusual or suspicious activity.

Conclusion

This incident underscores the evolving sophistication of hackers in exploiting cloud services for financial gain. It serves as a critical reminder for all AWS users to remain vigilant and proactive in monitoring their systems for any signs of intrusion.
