  1. Apple accidentally unpatched a vulnerability it had already fixed, making current versions of iOS vulnerable to hackers. Apple has mistakenly made it a bit easier to hack iPhone users who are on the latest version of its mobile operating system iOS by unpatching a vulnerability it had already fixed. Hackers quickly jumped on this over the weekend, and publicly released a jailbreak for current, up-to-date iPhones—the first free public jailbreak for a fully updated iPhone that's been released in years. Security researchers found this weekend that iOS 12.4, the latest version released in June, reintroduced a bug found by a Google hacker that was fixed in iOS 12.3. That means it’s currently relatively easy to not only jailbreak up to date iPhones, but also hack iPhone users, according to people who have studied the issue. “Due to 12.4 being the latest version of iOS currently available and the only one which Apple allows upgrading to, for the next couple of days (till 12.4.1 comes out), all devices of this version (or any 11.x and 12.x below 12.3) are jail breakable—which means they are also vulnerable to what is effectively a 100+ day exploit,” said Jonathan Levin, a security researcher and trainer who specializes in iOS, referring to the fact that this vulnerability can be exploited with code that was found more than 100 days ago. Pwn20wnd, a security researcher who develops iPhone jailbreaks, published a jailbreak for iOS 12.4 on Monday. For years, jailbreaks have been held closely to the chest by security researchers, because the ability to jailbreak an iPhone means the ability to hack it. As we've reported several times, exploits for the iPhone can sell for millions of dollars, which means that no one has been willing to release jailbreak code publicly because Apple will quickly patch it. A security researcher who hacks iPhones for a living, and who spoke on condition of anonymity because he wasn’t authorized to speak to the press, said that organizations that have the expertise to target iPhones can now use a bug in Safari, for example, to “ hack any up to date iPhone.” While it’s still not trivial to hack an iPhone remotely—even with the availability of this bug—the barriers to entry are now much lower. Apple did not immediately respond to a request for comment. Ned Williamson, who works at Google Project Zero, confirmed that the jailbreak works on his iPhone XR. “A user apparently tested the jailbreak on 12.4 and found that Apple had accidentally reverted the patch,” Williamson told Motherboard. The researcher told Motherboard that “somebody could make a perfect spyware” taking advantage of Apple’s mistake. For example, he said, a malicious app could include an exploit for this bug that allows it to escape the usual iOS sandbox—a mechanism that prevents apps from reaching data of other apps or the system—and steal user data. Another scenario is a hacker including the exploit in a malicious webpage, and pairing it with a browser exploit, according to the researcher. “It is very likely that someone is already exploiting this bug for bad purposes,” Pwn20wnd said. Several iPhone users on Twitter claimed to have successfully jailbroken their up to date iPhones with Pwn20wnd jailbreak. iPhone security experts are warning users to be careful what apps they download. “I hope people are aware that with a public jailbreak being available for the latest iOS 12.4 people must be very careful what Apps they download from the Apple AppStore,” Stefan Esser, a well-known researcher who teaches iOS hacking, wrote on Twitter. “Any such app could have a copy of the jailbreak in it.” Source
  2. We can all be friends — You can now jailbreak an iPhone with an Android phone Jailbreak exploit Checkra1n now runs on Linux, which means it runs on Android, too. Enlarge / Android teaches a young iPhone all about privilege escalation. Stblr / Reddit 7 with 7 posters participating We all have our differences in the tech world—PC versus Mac, Android versus iOS, Emacs versus Vim. Occasionally, though, we can reach out to our friends across the aisle and realize that, at the end of the day, we're not all that different. Today's uplifting message of unity comes from the two main smartphone factions sharing in the joys of privilege escalation: it's now possible for a rooted Android phone to jailbreak iOS. As first spotted by XDA Developers, Reddit user Stblr put the jailbreak puzzle pieces together when iOS jailbreaking exploit "Checkra1n" gained Linux support, which means it can also run on Android. If you have a rooted phone, you can plug your Android phone into your iPhone, run a few terminal commands, and break out of the Apple sandbox. Checkra1n is the first jailbreak compatible with iOS 13, and it works on the iPhone 5 to iPhone X, running iOS 12.3 and up. It's only a temporary jailbreak, though, and will get wiped out once the phone reboots. This makes an ultra-portable device that can kick your iPhone back over into jailbreak mode pretty handy, and—for now at least—Android phones are still a bit smaller than laptops. Checkra1n exploits iOS via the Device Firmware Upgrade (DFU) mode. This is a recovery mode meant to send a new OS to the device over USB, and a few bugs in the DFU USB implementation can kick off a jailbreak exploit chain. Regular Android phones can run a Linux terminal just fine, and they have USB host capabilities, but you need root access for full control over Android's USB stack. Checkra1n does some dirty tricks like interrupting USB transfers mid-way, and there's no user-level API for that. Since this is a USB exploit, you'll need to run a wire from the Android phone to the iPhone, which usually means some way of going from Android's USB-C to the iPhone's Lightning Cable (when are those USB-C iPhones coming, Apple?). DFU mode won't turn on unless a cable is plugged in, and Stblr notes that not every USB-C to Lightning Cable out there has the right pins to put an iPhone in DFU mode (including first-party cables!). Stblr ended up using a Lightning to USB-A cable and then a USB-A-to-C adapter. Source: You can now jailbreak an iPhone with an Android phone (Ars Technica)
  3. New jailbreak tool works on Apple’s just-released iOS 13.5 The jailbreak tool was built by hacking group Unc0ver Illustration by Alex Castro / The Verge A new tool by hacking group Unc0ver can jailbreak iOS 13.5, the just-released version of Apple’s mobile operating system, Wired reported. The group says the jailbreak, which works on iOS 11 and higher, is built on a zero-day vulnerability, doesn’t drain a device’s battery life, and doesn’t affect the use of Apple services or undermine the iOS sandbox security, according to Wired. Unc0ver’s lead developer told Wired the jailbreak adds exceptions to existing rules, and “enables reading new jailbreak files and parts of the filesystem that contain no user data.” The jailbreak tool is not open source, and the group didn’t say which vulnerability in iOS it exploited to build the tool. Jailbreaking gives a user more control over a device’s OS, allowing customization and the installation of apps that Apple would otherwise restrict. It also can be used by would-be attackers to compromise a device’s security. In earlier versions of iOS, jailbreaking was relatively common. The practice has dwindled in recent years with Apple making it more difficult to pull off, resulting in some of the most prominent jailbreak-reliant app sources closing down.

  4. just installed the new uncover to jailbreak my iPhone XR ON 12.4.1 but when I press jailbreak it restarts my phone and nothing happens... no Cydia or jailbreak
  5. There may be multiple different players in the jailbreak community all looking to offer solutions, but we’ve always admired those who keep trying to produce great work for the benefit of device owners. That admiration is extended to CoolStar, most recently for his creation and publishing of the Electra jailbreak for iOS 11, and the fact that it’s been tirelessly updated. Well, there is now a new update available, and it’s one you’re going to want to take notice of as it features a very special addition. CoolStar and his band of highly-capable merry men have finally released the final 1.0.x version of Electra jailbreak, complete with Cydia Installer support built right in. This version of Electra jailbreak is deemed stable enough and hence is marked as 1.0 rather than any beta or RC. Just about anyone can go ahead and download it right now. For those who don’t know, Electra works with iOS 11.0-11.1.2 firmwares and is compatible with all 64-bit devices, including iPhone X, as long as those devices are running the aforementioned compatible firmwares. This is because Electra is based of Ian Beer’s exploit which was only applicable on iOS 11.0-11.1.2. Original released back as beta in January sans Cydia, this latest final version of the tool is the first jailbreak for iOS 11 which offers support for Cydia out-of-the-box. As for the jailbreak process, it pretty much remains exactly the same. Once the latest version of the Electra jailbreak is downloaded, and the IPA is sideloaded to the device, the jailbreak process will be exactly as it was previously, but this time with the added benefit of actually installing a usable version of Cydia to the device. And yes, that means that compatible tweaks and packages will be able to be installed through the Cydia interface. Here are important notes from changelog of Electra 1.0.x: An APFS snapshot is created of / so you may revert it at a later date if needed Substitute, Tweak Loader and Substrate Compatibility Layer available from Electra repo Many packages need to be updated for both Electra and iOS 11 (make sure they’re updated before installing as they may not work yet) It’s great news for device owners that CoolStar and his highly capable team have once again put the effort to the benefit of the jailbreak community even before Saurik could come up with his own “promised” jailbreak with iOS 11 Cydia update. Final version of Electra jailbreak for iOS 11 can be downloaded from coolstar.org/electra/. Once downloaded, you can follow our guide here on how to jailbreak your device using Electra: How To Jailbreak iOS 11.1.2 Using Electra With Cydia [Tutorial]. Redmondpie.com
