LocCheck : A Tool For Simplifying The Process Of Researching IOCs

LocCheck is a tool for simplifying the process of researching file hashes, IP addresses, and other indicators of compromise (IOCs).

Features

• Look up hashes across multiple threat intelligence services, from a single command or a few lines of Python.
• Currenty supports the following services:
  • VirusTotal
  • MalwareBazaar
  • Shodan.io
• Planned support:
  • URLhaus
  • OTX
  • InQuest Labs
  • MalShare
  • Malpedia
  • Maltiverse

Quickstart

pip install ioccheck

You can also run the code directly

git clone https://github.com/ranguli/ioccheck && cd ioccheck
poetry install

Using the API

Creating a hash

>>>from ioccheck import Hash
>>>from ioccheck.services import VirusTotal
>>>eicar = Hash(“275a021bbfb6489e54d471899f7db9d1663fc695ec2fe2a2c4538aabf651fd0f”)
>>> #what kind of hash is this?
>>>print(eicar.hash_type)
SHA256

Looking up a hash

>>> # With no arguments, check() tries all supported services. API keys grabbed from ~/.ioccheck by default.
>>>eicar.check()
>>> #Alternatively:
>>>eicar.check(services=VirusTotal, config_path=/foo/bar/.ioccheck)

Researching a hash

>>>Check the VirusTotal report to see if Sophos detects our hash
>>>eicar.reports.virustotal.get_detections(engines=[“Sophos”])
{‘Sophos’: {‘category’: ‘malicious’, ‘engine_name’: ‘Sophos’, ‘engine_version’: ‘1.0.2.0’, ‘result’: ‘EICAR-AV-Test’, ‘method’: ‘blacklist’, ‘engine_update’: ‘20210314’}}
>>> #What is this hash known as?
>>> print(eicar.reports.virustotal.name)
‘eicar.com-2224’
>>> # How many AV engines are detecting this hash?
>>> eicar.reports.virustotal.detection_count
60

>>> # Just show me the VirusTotal API response!
>>> eicar.reports.virustotal.api_response
