The Unc0ver tool works on all versions of iOS from 11 to 13.5, the current release.
OVER THE YEARS, Apple has made it prohibitively difficult to install unapproved software on its locked-down devices. But on Saturday, a hacker group called Unc0ver released a tool that will “jailbreak” all versions of iOS from 11 to 13.5. It’s been years since a jailbreak has been available for a current version of iOS for more than a few days—making this yet another knock on Apple’s faltering security image.
Unc0ver says that its jailbreak, which you can install using the longtime jailbreaking platforms AltStore and Cydia (but maybe don’t unless you’re absolutely sure you know what you’re doing), is stable and doesn’t drain battery life or prevent use of Apple services like iCloud, Apple Pay, or iMessage. And the group claims that it preserves Apple’s user data protections and doesn’t undermine iOS’ sandbox security, which keeps programs running separately so they can’t access data they shouldn’t.
“This jailbreak basically just adds exceptions to the existing rules,” Unc0ver’s lead developer, who goes by Pwn20wnd, told WIRED. “It only enables reading new jailbreak files and parts of the file system that contain no user data.”
Early public reactions to the jailbreak, including from researchers who tested it before its release, indicate that it works as intended. But the community hasn’t yet had time to fully assess the jailbreak or Unc0ver’s claims about its security protections. And the tool isn’t open source, which means it will be more difficult to analyze.
“It’s very in line with the early jailbreak spirit.”
