This Week’s Top Story
Twitter gets subpoena to find source code leak
Twitter asked the U.S. District Court for the Northern District of California to issue a subpoena to GitHub in an attempt to find information on a particular user that leaked portions of Twitter’s source code, ArsTechnica reported. A court clerk signed off on the subpoena this past Tuesday, giving GitHub until April 3 to share details about the user, known as “FreeSpeechEnthusiast.” This user posted Twitter’s source code back in January, not long after Elon Musk bought the company and laid off thousands of its employees. Twitter does suspect that this user is one of its ex-employees who was laid off that same month.
On March 24, Twitter not only asked for the subpoena, but also filed a Digital Millennium Copyright Act (DMCA) notice to GitHub, which prompted GitHub to take down the leaked source code from its platform. Twitter’s DMCA notice also requested information on FreeSpeechEnthusiast, but GitHub did not share those details with Twitter immediately. Thanks to the issued subpoena, Github only has until this Monday to share this user information with Twitter.
According to the now-issued subpoena (PDF), GitHub will need to provide all identifying information on FreeSpeechEnthusiast, including the names, addresses, telephone numbers, email addresses, social media profile data, and IP addresses associated with the user’s account. GitHub will also have to provide this same information for any user that posted, downloaded, uploaded or modified the data in any way.
Twitter’s reasoning behind the subpoena, according to company executives, is that there is concern “that the code includes security vulnerabilities that could give hackers or other motivated parties the means to extract user data or take down the site.” Twitter also did not know about the leaked source code until months after it was posted on GitHub.
