They address precisely the topic of “do you store my code or not?”. To start, we have a few very positive points in Codecov’s design for security: Source: Bleeping Computer Other possible attack vectorsīy reading Codecov’s documentation and surveying possible additional attack vectors, we’re going to extract a few more lessons to take home.

This basically means a really bad day to a whole lot of people. The git remote information (URL of the origin repository) of repositories using the Bash Uploaders to upload coverage to Codecov in CI. The official security update states the following impact because the bash uploader was also used in CI providers:Īny credentials, tokens, or keys that our customers were passing through their CI runner that would be accessible when the Bash Uploader script was executed.Īny services, datastores, and application code that could be accessed with these credentials, tokens, or keys. Not to mention - access to the source code at hand. It would be a hub of sensitive access actions, and so, a great place to look for access details, credentials, and more. And the ROI is clear: as CI providers often host jobs for integration, end-to-end testing, data access, and more. So the motive here would be to see how to side-step into the more interesting area – the CI provider. The impact is more massive than it should have been.

Since we’re now in the CI realm (and Codecov is not a CI provider but has integration with these providers via this bash script). There was also a blast radius here, because that meant, according to the official security update, that these were affected too:Ĭodecov-actions uploader for Github, the Codecov CircleCl Orb, and the Codecov Bitrise Step (together, the “Bash Uploaders”). The actor gained access because of an error in Codecov’s Docker image creation process that allowed the actor to extract the credential required to modify our Bash Uploader script. On Thursday, April 1, 2021, we learned that someone had gained unauthorized access to our Bash Uploader script and modified it without our permission.

Optionally, make sure to “tuck in” some metadata if the coverage vendor product is offering some more “extras” such as drilling down to code, or pinpointing uncovered lines with their surrounding contextįrom the official Codecov security update we learn that this tool is indeed their bash upload script:.

Upload a coverage report to a central server, locally or from a CI provider.

“The tool” probably means Codecov’s uploaders, for various programming languages, and what it does is similar to any coverage SDK - understand all outputs of popular coverage formats and: These are actions we can take to protect ourselves and our code as soon as tomorrow morning.Īccording to Reuters: “Codecov makes software auditing tools that allow developers to see how thoroughly their own code is being tested, a process that can give the tool access to stored credentials for various internal software accounts.”

Lessons learned: Immediate and key takeaways for all of us.

Let’s squeeze some more juice out of the lemon, and see what more we can learn.

Impact and forensics: An analysis of what was or could be the attack vectors as it stands right now.

Interest, motive, and ROI: What could be in it for an attacker? This helps figure out how attackers think.

To get the best value of our analysis, We’re going to look at: Our goal? To extract actionable insights anyone can apply in order to avoid being the next victim or collateral damage of such a breach. With only limited facts at our disposal (the breach report on Codecov’s blog and press release by Reuters), we’re going to try and analyze the breach. we used to put code coverage on a local Jenkins in the old days), is entrusted with an external, cloud-based vendor adding it to the supply chain of value to the end-user. In this specific case the value of code coverage analysis (which used to be local to an organization i.e.
