A massive archive of TestFlight files was discovered on the Wayback Machine and the files were shared anonymously on X (the social network formerly known as Twitter). The exposure of the archive could cause a reappearance of thousands of classic iOS apps and games that are no longer available in the App Store.
Eurogamer reports:
The files, which include prototype and beta versions of apps and games, are from 2012 to 2015 and predate when Apple acquired TestFlight. It appears that the content may have come from a cloud storage server that had the wrong configuration, and it was actually uploaded in March 2015 from the old TestFlightApp.com website. Content went unnoticed until it was surfaced on Twitter.
The @teraleak account is sharing the game and app files that have been found in the archive. Some of the titles that have appeared include unreleased versions of Angry Birds, the canceled game Infinity Blade Dungeons, a Sonic Dash prototype, and more.
The leak will have the effect of seeing many apps and games that were removed from the App Store become available once more. It should be noted that the leaked games and apps likely won’t run on modern devices, although there may be workarounds.
