Pakistani Hacker Posted Authentic Snapchat Source Code on GitHub – Snapchat’s source code is stolen…can there be a bigger news than that? Perhaps there is!
Not only that the source code has been stolen but also posted on Microsoft-owned GitHub of all the platforms. Reportedly, the hacker hails from a small village in Pakistan and uses the alias ‘i5xx’.
It is alleged that the hacker obtained the source code when the company released an iOS update in May 2018. As expected, Snapchat filed a takedown request under the Digital Millennium Copyright Act (DMCA) and GitHub readily complied by removing it in-time.
