Rapid7 Source Code Exposed in Codecov Supply Chain Attack

Rapid7 says unauthorized third-party accessed source code, customer data during Codecov supply chain breach

Enterprise security vendor Rapid7 says it was among the victims of the Codecov software supply chain attack and warned Thursday that data for a subset of its customers was accessed in the breach.

Rapid7, widely known for its tools that automate security assessments, said an internal investigation found that “a small subset of our source code repositories for internal tooling for our MDR service was accessed by an unauthorized party outside of Rapid7.”

The company said the repositories contained internal credentials and alert-related data for a subset of its MDR (managed detection and response) customers. The credentials have all been rotated since the disclosure of the Codecov breach.

The supply chain hack on Codecov happened in mid-January and was discovered in the wild by a Codecov customer on the morning of April 1, 2021 when the company said it learned that someone had gained unauthorized access to the Bash Uploader script and modified it without permission, leading to exposed sensitive secrets like tokens, keys and credentials from organizations around the world.

In addition to Rapid7, Twilio and HashiCorp have publicly confirmed being caught in the CodeCov blast radius.

In a statement, Rapid7 said its use of Codecov’s Bash Uploader script was limited and set up on a single CI server used to test and build some internal tooling for its Managed Detection and Response (MDR) service. 

However, an investigation found some damage, and Rapid7 says it determied the following:

• A small subset of our source code repositories for internal tooling for our MDR service was accessed by an unauthorized party outside of Rapid7

• These repositories contained some internal credentials, which have all been rotated, and alert-related data for a subset of our MDR customers

• No other corporate systems or production environments were accessed, and no unauthorized changes to these repositories were made

Boston-based Rapid7 said it contacted the affected customers to ensure they take appropriate steps to mitigate any potential risk.   

The massive blast radius from the Codecov supply chain attack remains shrouded in mystery as security teams continue to assess the fallout from the breach but victims continue to publicly acknowledge possible exposure of sensitive developer secrets.
