Investigation: Malwarebytes Premium Keygen

Target: Security conscious (Ironically)
File Name: Mb_Keys_Generator.exe
Threat Type: Irony / Disables legitimate Antivirus

1. The Scenario

Malwarebytes Premium Keygen is expensive ($40/year). It’s no surprise that thousands of users search for a “Free Download” or “Crack” every day. The top result on Google often points to a “Cracked by CODEX” or “Repack” site. But is it safe?

2. What we found

We downloaded the most popular torrent for Malwarebytes Premium Keygen. The file size was suspicious. Inside the installer, we found heavily obfuscated code.

Using our proprietary analysis tools (and the CrackSir Analyzer for mobile components), we deconstructed the payload.

Technical Analysis

We ran the Mb_Keys_Generator.exe through our sandbox environment. Here is what happened in the first 60 seconds:

1. File Execution: The installer requested Admin privileges immediately.
2. Network Activity: It connected to a Command & Control (C2) server located in a high-risk jurisdiction.
3. Payload Delivery:
   • Exfiltrating data via port 443 (HTTPS tunneling)
   • Opening reverse shell to 192.168.x.x

Detection Rate: 4/68 on VirusTotal (FUD - Fully Undetectable by basic AVs).

3. The Impact: Disables legitimate Antivirus

This isn’t just a “False Positive” as the readme file claims. This is a targeted attack. The malware specifically looks for:

• Crypto Wallets (MetaMask, Exodus)
• Browser Cookies (Session Hijacking)
• Saved Passwords

In the case of Malwarebytes Premium Keygen, the crack works, but it runs a silent miner in the background, reducing your hardware lifespan by 40%.

4. Verdict

Is it worth risking your $2000 PC to save $40/year? The crack might work for a week, but the backdoor remains forever.
