GitHub has reportedly been hacked. A group called TeamPCP claims it gained unauthorized access to GitHub’s internal systems and stole data from around 4,000 private and internal repositories, including source code and company files. They are now trying to sell this stolen data for more than $50,000 on underground forums and have said they will release it for free if no one buys it. GitHub is investigating the unauthorized access and says it has found no evidence so far that customer data, organizations, or customer repositories were affected.
