Libretro Github


A place to discuss all things libretro. Category Topics; Announcements. RetroArch is a frontend for emulators, game engines and media. Welcome to the Libretro/RetroArch Documentation!¶ RetroArch is the official reference frontend for libretro 'cores': applications that include emulators, game engines, and media players. Settings are also unified across cores with advanced features like shaders, netplay, rewinding, and more!

libretro (formerly libsnes) is an API designed mainly for games and emulators. It allows games and emulators to be compiled as dynamically linked libraries known as 'libretro cores', which can be used in a frontend that implements libretro, such as RetroArch.

In an announcement, the Libretro / RetroArch mentioned how the Libretro / RetroArch organization on GitHub was attacked by hackers and they managed to do quite a bit of damage.

While restoration is ongoing, some of it is going to be more difficult. In the announcement, they mentioned the scale of the damage that was done comes down to:

  • He accessed our buildbot server and crippled the nightly/stable buildbot services, and the netplay lobby service. Right now, the Core Updater won’t work. The websites for these have also been rendered inaccessible for the moment
  • He gained access to our Libretro organization on Github impersonating a very trusted member of the team and force-pushed a blank initial commit to a fair percentage of our repositories, effectively wiping them. He managed to do damage to 3 out of 9 pages of repositories. RetroArch and everything preceding it on page 3 has been left intact before his access got curtailed.

GitHub themselves have replied (source) to mentioned they can't help, so they're now relying on local backups and Git history from their developers to get it back to where it was online.

Some good news though: for users they said no Cores or RetroArch installs should be considered compromised, as the attacker was too busy with wiping things and being a nuisance. However, thanks to it the Core installer is offline as are the 'Update Assets', 'Update Overlays', 'Update Shaders' functions.

Also mentioned is how they didn't have automated backups of their buildbot, a service which helps to automate building the application and testing. Something that's generally vital for larger projects. They said it's due to funding, as they don't have enough for it with a note about supporting them on Patreon to help.

This is another reminder of: backups, backups—backups! More than that though, it's also an example of why two factor authentication is also vitally important. This little detail was left out of their announcement, but they didn't force 2FA which appears to be how the attacker actually got in. Speaking on Twitter, they mentioned how some developers felt it was 'too much of a pain' and they didn't want to lose those contributors. Well, was it worth it? Let's hope proper security will be implemented now.
