GitHub on Tuesday said it's investigating unauthorized access to its internal repositories after the notorious threat actor known as TeamPCP listed the platform's source code and internal organizations for sale on a cybercrime forum.
"While we currently have no evidence of impact to customer information stored outside of GitHub's internal repositories (such as our customers' enterprises, organizations, and repositories), we are closely monitoring our infrastructure for follow-on activity," the Microsoft-owned subsidiary said.
The company also noted that it will notify customers via established incident response and notification channels if any impact is discovered.
The development comes after TeamPCP, a threat actor behind a string of software supply chain attacks targeting open-source packages, listed GitHub's source code for sale for an asking price of no less than $50,000. The alleged data dump is said to include about 4,000 repositories.
"As always, this is not a ransom," the group said in a post, according to screenshots shared by Dark Web Informer. "We do not care about extorting GitHub, 1 buyer and we shred the data on our end, it looks like our retirement is soon so if no buyer is found, we leak it for free."
