Developers beware: GitHub Actions vulnerable to hidden malicious code threat

TLDR:

• GitHub Actions is vulnerable to typosquatting, exposing developers to hidden malicious code.
• Malicious actors can create organizations and repositories with names similar to popular GitHub Actions to trick developers.

Article Summary:

Threat actors have been exploiting typosquatting to target unsuspecting users, and now they are leveraging this technique to target developers using GitHub Actions. By creating organizations and repositories with names similar to popular GitHub Actions, malicious actors can trick developers into running malicious code without their knowledge. This can lead to tampering with source code, stealing secrets, and delivering malware. The attack is possible because anyone can publish a GitHub Action, and if a developer makes a typo that matches a typosquatter’s action, the malicious code can be executed.

A security researcher from Orca shared that search results revealed numerous files that incorrectly invoke certain actions, putting projects at risk. This low-cost, high-impact attack could compromise multiple downstream customers of affected projects. To prevent such attacks, users are advised to double-check actions, stick to trusted sources, and regularly scan CI/CD workflows for typosquatting issues.

The impact on private repositories remains unknown, highlighting the importance of vigilance and best practices in preventing supply chain compromises. By being cautious and following recommended security measures, developers can protect their projects from these types of attacks.
