Mrida

An opensource antivirus implementation - Successor of CyberGod KSGMPRH

Mrida is an open source antivirus implementation which uses YARA and LSH to detect malicious programs. It is programmed using C++ 14.

Requesting to scan a file with YARA signatures:

import requests
r = requests.post("http://127.0.0.1:5660/scan_file_for_yara", data={"file": "D:/test.eicar", "target": "windows"})
r.json()

OUTPUT:

{
  "detections": [
    {
      "author": "Visweswaran",
      "description": "BOT",
      "name": "bot"
    },
    {
      "author": "UNKNOWN AUTHOR",
      "description": "EXAMPLE - 1",
      "name": "example"
    }
  ],
  "message": true
}

Getting List of packers:

import requests
r = requests.post("http://127.0.0.1:5660/scan_file_for_packer", data={"file": "D:/git-bash.exe"})
r.json()

OUTPUT:

{
  "detected": [
    "Microsoft_Visual_Cpp_80_DLL"
  ]
}

Getting Shannon Entropy for file:

r = requests.post("http://127.0.0.1:5660/shannon_entropy_for_file", data={"file": "D:/git-bash.exe"})
r.json()

OUTPUT:

{
  "entropy": 4.221405214084764
}

Check whether a domain is blocked or not

http://127.0.0.1:5660/is_domain_blocked?host=www.test.com

OUTPUT:

{
  "message": false
}

Perform virustotal scan on all running process:

r = requests.post("http://127.0.0.1:5660/proc_scan", data={"type": "gui", "api": "[YOUR KEY]"})

Getting the tlsh similarity distance for two hashes

r = requests.get("http://127.0.0.1:5660/get_tlsh_distance?hash_one=B0648D22F7D290B5D063033049BCA2BAA67FFDBFD920825BB3C4631E4DB0791AE35F56&hash_two=B0648D22F7D290B5D063033049BCA2BAA67FFDB55920825BB3C4631E4DB0791AE35F56")
r.json()

OUTPUT:

{
  "message": 6
}

Check the threat database for matching hash. If nothing is matched will return -1

r = requests.get("http://127.0.0.1:5660/check_threat_db?tlsh=FC55ADF47998802EC02A4437B961A6D96B307C975C865813FEA8BB1D3CEF160FD09677&min_size=3500&max_size=3543005&type=application/x-msdownload")
r.json()
