AI-powered malware hit 2,180 GitHub accounts in “s1ngularity” attack
Investigations into the Nx “s1ngularity” NPM supply chain attack have unveiled a massive fallout, with thousands of account tokens and repository secrets leaked. According to a post-incident evaluation by Wiz researchers, the Nx compromise has resulted in the exposure of 2,180 accounts and 7,200 repositories across three distinct phases. Wiz also stressed that the incident’s scope […]
Recent GitHub supply chain attack traced to leaked SpotBugs token
A cascading supply chain attack on GitHub that targeted Coinbase in March has now been traced back to a single token stolen from a SpotBugs workflow, which allowed a threat actor to compromise multiple GitHub projects. The popular static analysis tool SpotBugs was breached in November 2024, leading to the compromise of Reviewdog, which subsequently […]
Coinbase was primary target of recent GitHub Actions breaches
Researchers have determined that Coinbase was the primary target in a recent GitHub Actions cascading supply chain attack that compromised secrets in hundreds of repositories. According to new reports from Palo Alto Unit 42 and Wiz, the attack was carefully planned and began when malicious code was injected into reviewdog/action-setup@v1 GitHub Action. It is unclear how the breach occurred, but […]
GitHub Action supply chain attack exposed secrets in 218 repos
The compromise of GitHub Action tj-actions/changed-files has impacted only a small percentage of the 23,000 projects using it, with it estimated that only 218 repositories exposed secrets due to the supply chain attack. Despite the small number, the potential security repercussions are still significant as some repositories are very popular and could be used in […]
GitHub Action hack likely led to another in cascading supply chain attack
A cascading supply chain attack that began with the compromise of the “reviewdog/action-setup@v1” GitHub Action is believed to have led to the recent breach of “tj-actions/changed-files” that leaked CI/CD secrets. Last week, a supply chain attack on the tj-actions/changed-files GitHub Action caused malicious code to write CI/CD secrets to the workflow logs for 23,000 repositories. If those […]
Supply chain attack on popular GitHub Action exposes CI/CD secrets
A supply chain attack on the widely used ‘tj-actions/changed-files’ GitHub Action, used by 23,000 repositories, potentially allowed threat actors to steal CI/CD secrets from GitHub Actions build logs. The GitHub Action is a very popular automation tool designed for GitHub Actions workflows. It allows developers to identify files changed in a pull request or commit […]
GitHub Actions artifacts found leaking auth tokens in popular projects
Multiple high-profile open-source projects, including those from Google, Microsoft, AWS, and Red Hat, were found to leak GitHub authentication tokens through GitHub Actions artifacts in CI/CD workflows. Attackers stealing these tokens could gain unauthorized access to private repositories, steal source code, or inject malicious code into projects. The discovery by Palo Alto Networks’ Unit 42 […]
