GitHub, the widely-used code hosting platform owned by Microsoft, has confirmed a significant data breach affecting around 3,800 internal code repositories. The breach was traced back to a compromised Visual Studio Code (VS Code) extension, which is a popular plugin among developers. GitHub stated that it has found no evidence indicating that customer information stored outside its internal repositories has been impacted, but the investigation remains ongoing. The hackers, identified as TeamPCP, have claimed responsibility for this breach and are reportedly selling the stolen data on a cybercrime forum. This incident underscores a worrying trend where hackers target popular open-source projects to gain access to a large number of developers' systems simultaneously. GitHub has not revealed the identity of the compromised extension or whether it has received any ransom demands from the attackers. This breach follows other high-profile attacks, including one against the European Commission, where hackers stole over 90 gigabytes of data, and another targeting OpenAI.
