Over 5,500 GitHub Repositories Infected in ‘Megalodon’ Supply Chain Attack
More than 5,500 GitHub repositories were infected with malware in a supply chain attack that relies on automated commits, security researchers warn.
The campaign, dubbed Megalodon, relies on GitHub Actions workflows containing a payload designed to steal credentials, keys, tokens, and other secrets.
The workflows, SafeDep says, were injected through over 5,700 malicious commits pushed to the impacted repositories within a six-hour window, on May 18.
According to the cybersecurity firm, the attackers deployed two payloads as part of the attack. One was designed to add a new workflow that would be triggered on every push and pull request, and another that replaced existing workflows with specific triggers, creating dormant backdoors.
