I'm learning malware analysis. I'm looking for malware samples that terminate themselves when recognize working on a VM or sandbox.

  • I propose having a look at early cerber samples (9e82344a0a854411fd095f070b0782e8), they feature a debug mode, few obfuscation tricks and the whole range of basic anti-vm-techniques (have a look at 0x401307)

  • @Nordwald Do you know where I can download these samples of cerber? (I have tried searching with the given hash but cannot found any) May 4, 2017 at 7:55
  • @TaThanhDinh This is only the hash of a sample I analyzed personally, but any of the early-samples should suffice as an example. Sadly, apart from commercial solutions like VirusTotal, malware repositories are awfully bad maintained. You may try malpedia or openMalware for example

For learning purposes, I would recommend you the following Github projects to start with:

Paranoid Fish by a0rtega


Al-Khaser v0.60 by Noteworthy



Colection by AlicanAkyol


Grab one you like, compile and analyze.

In case you look for in the wild samples, you should look at Andromeda\Gamarue bot. It have a plenty of anti tricks, including anti-VM, anti-Sandbox, anti-research etc.


https://github.com/a0rtega/pafish is old but it is good tool. https://github.com/AlicanAkyol/sems is current. You can use it.

    Answers that are merely links are not encouraged, may I interest you writing at least a couple of sentences about the tools?

  • I used the tools for malware analysis. And these tools have given successful result. But I like sems more than pafish. May 4, 2017 at 20:20
