Millions of software program repositories on GitHub are likely vulnerable to an attack named RepoJacking, a new review has discovered.
This involves repositories from corporations these types of as Google, Lyft, and several other individuals, Massachusetts-centered cloud-indigenous security firm Aqua said in a Wednesday report.
The provide chain vulnerability, also recognised as dependency repository hijacking, is a course of attacks that helps make it possible to choose in excess of retired organizations or person names and publish trojanized variations of repositories to operate malicious code.

“When a repository operator variations their username, a connection is developed concerning the previous title and the new identify for any person who downloads dependencies from the aged repository,” researchers Ilay Goldman and Yakir Kadkoda mentioned. “However, it is achievable for everyone to produce the outdated username and crack this connection.”
Alternatively, a comparable circumstance could come up when a repository possession is transferred to yet another person and the first account is deleted, hence permitting a poor actor to generate an account with the outdated username.
Aqua stated a risk actor could leverage web-sites like GHTorrent to extract GitHub metadata involved with any public commits and pull requests to compile a list of exceptional repositories.
An investigation of a subset of 1.25 million repositories for the month of June 2019 revealed that as a lot of as 36,983 repositories had been susceptible to RepoJacking, denoting a 2.95% achievement charge.
With GitHub made up of a lot more than 330 million repositories, the conclusions advise that tens of millions of repositories could be vulnerable to a very similar attack.
One this sort of repository is google/mathsteps, which was beforehand beneath the possession of Socratic (socraticorg/mathsteps), a enterprise that was acquired by Google in 2018.

“When you obtain https://github.com/socraticorg/mathsteps, you are staying redirected to https://github.com/google/mathsteps so eventually the consumer will fetch Google’s repository,” the researchers claimed.
“Nonetheless, for the reason that the socraticorg organization was readily available, an attacker could open up the socraticorg/mathsteps repository and people subsequent Google’s guidelines will clone the attacker’s repository alternatively. And due to the fact of the npm install this will guide to arbitrary code execution on the customers.”
This is not the initially time such considerations have been raised. In October 2022, GitHub moved to near a security loophole that could have been exploited to produce malicious repositories and mount supply chain attacks by circumventing common repository namespace retirement.
To mitigate these threats, it can be advisable that users periodically inspect their code for one-way links that may perhaps be retrieving methods from exterior GitHub repositories.
“If you improve your group identify, ensure that you nevertheless personal the previous title as effectively, even as a placeholder, to protect against attackers from building it,” the researchers mentioned.
