GitHub Supply Chain Attack: SpotBugs Access Token Theft Identified

TL;DR

The GitHub supply chain attack, which initially targeted Coinbase and users of the “tj-actions/changed-files” GitHub Action, has been traced back to the theft of a personal access token (PAT) related to SpotBugs. This article explores the attack’s origins, its impact, and the broader implications for cybersecurity.

Introduction

The recent supply chain attack on GitHub, which initially targeted Coinbase and later affected users of the “tj-actions/changed-files” GitHub Action, has been traced back to the theft of a personal access token (PAT) related to SpotBugs. This attack highlights the vulnerabilities in modern software development pipelines and the critical importance of securing access tokens.

The Attack Vector

The attackers gained initial access by exploiting the GitHub Actions workflow of SpotBugs, a popular open-source tool for static code analysis. By stealing a personal access token, the attackers were able to infiltrate the supply chain and compromise multiple targets. This incident underscores the need for robust security measures in open-source projects and the broader software development ecosystem.

Impact and Implications

The theft of the SpotBugs PAT had cascading effects, impacting not only Coinbase but also a wider range of users who relied on the “tj-actions/changed-files” GitHub Action. This incident serves as a reminder of the interconnected nature of modern software development and the potential for supply chain attacks to have far-reaching consequences.
