Gitcolombo - Extract And Analyze Contributors Info From Git Repos


OSINT tool to extract info about persons from git repositories: common names, emails, matches between different (as it may seems) accounts.

Using

  1. Install git

  2. Run:

    repos by nickname ./gitcolombo.py --nickname LubyRuffy">
     # from any git url
    ./gitcolombo.py -u https://github.com/Kalanchyovskaia16/newlps

    # from directory, recursively
    ./gitcolombo.py -d ./newlps -r

    # from all GitHub personal/org repos by nickname
    ./gitcolombo.py --nickname LubyRuffy

For batch cloning from Gitlab and Bitbucket group repos you can use ghorg.


Output:

  • verbose persons info

    • name
    • email
    • number of appearences as author/committer
    • other persons that person can be
  • emails used for the same name

  • different names for the same person

  • general statistics

What's the difference between git author and committer?

TL;DR

  • author wrote the code (make the patch)
  • commiter commit it to the repo (rewrite history, make pull/merge requests...)

Nice explanation: https://stackoverflow.com/questions/18750808/difference-between-author-and-committer-in-git

Very often developers make inaccurate commits with the one name/email (e.g. work account), then change to the right (e.g. personal account) and make git commit --amend, but forget to change the author of the commit. This way we can use it for OSINT as match of names/emails from git history.

TODO

  • Total statistics for repos in a directory
  • Check different names for every email
  • GitHub support: clone all repos from account/group
  • GitHub support: api pagination
  • GitHub support: extract links to accounts from commit info
  • Exclude "system" accounts (e.g. [email protected])
  • Probabilistic graph links based on same names/emails and Levenshtein distance
  • Other popular git platforms: Gitlab, Bitbucket and also
