Prerequisite: A VirusTotal API key is required and must be set as an environment variable with a name of VT_API_KEY. Get a free public API key by completing the signup at https://www.virustotal.com/gui/join-us.

1. Download or clone the vtlookup repository
   git clone https://github.com/bradsec/vtlookup.git

2. Set the VT_API_KEY environment variable:

For Linux users -

VT_API_KEY="YOUR_VIRUSTOTAL_APIKEY"
export VT_API_KEY

For Windows users -

setx VT_API_KEY "YOUR_VIRUSTOTAL_APIKEY"

• Lookup using plain text hash (hashValue can be md5, sha1, or sha256) -
  python3 vtlookup.py -hash hashValue
  The below example will return detections:
  python3 vtlookup.py -hash a2f6b977b849ba588b88c81b68b4535c

• Lookup by getting the sha256 hash from a local file -
  python3 vtlookup.py -file specifyfilename.ext

• Offline debug using the included test.json file -
  python3 vtlookup.py -debug test.json
