Cloud-based code hosting platform GitHub described the recent attack campaign involving the abuse of OAuth access tokens issued to Heroku and Travis-CI as “highly targeted” in nature.
“This pattern of behavior suggests the attacker was only listing organizations in order to identify accounts to selectively target for listing and downloading private repositories,” GitHub’s Mike Hanley said in an updated post.
The security incident, which it discovered on April 12, related to an unidentified attacker leveraging stolen OAuth user tokens issued to two third-party OAuth integrators, Heroku and Travis-CI, to download data from dozens of organizations, including NPM.
