"Apple marketing has done a great job convincing people that macOS is secure, and I think that this is rather irresponsible and leads to issues where Mac users are overconfident and thus more vulnerable," he added. I felt that users should be aware of the risks that are out there I'm sure sophisticated attackers have similar capabilities." "I don't mean that to be taken personally by anybody at Apple - but every time I look at macOS the wrong way something falls over. "As a passionate Mac user, I'm continually disappointed in the security of macOS," he said.
#MAC KEYCHAIN ACCESS VULNERABILITY PATCH#
He reported the bug to Apple earlier this month, "but unfortunately the patch didn't make it into High Sierra," he said, which was released Monday. "If I was an attacker or designing a macOS implant, this would be the 'dump keychain' plugin," said Wardle. That exploit could be included in a legitimate-looking app, or be sent by email. Wardle created a "keychainStealer" app demonstrating a local exploit for the vulnerability, which according to the video, can expose passwords to websites, services, and credit card numbers when a user is logged in.

#MAC KEYCHAIN ACCESS VULNERABILITY UPGRADE#
However, some users are unable to upgrade from Sierra to High Sierra until compatible versions of the applications they use are released, eg Adobe Illustrator.Īnd sometimes it appears that seemingly important security patches get thrown into the "too hard" basket – for example, the Broadpwn issue was only addressed in Sierra (and later), but it has been shown to affect Yosemite and El Capitan, and not all Macs running Yosemite can be upgraded to Sierra.3G shutdown is underway: Check your devices now The company's position - which can only be inferred from what it does and does not release - seems to be that if a newer version of an operating system has the same hardware requirements as its predecessor, it feels no compulsion to offer a patch for the latter. There is no indication from Apple that a fix will be forthcoming for those versions.
#MAC KEYCHAIN ACCESS VULNERABILITY UPDATE#
The update is available via the Mac App Store or from Apple's website.īut according to Wardle, macOS Sierra 10.12 is also vulnerable, and "El Capitan appears vulnerable as well". Non-security changes in the update "Improves installer robustness", "Fixes a cursor graphic bug when using Adobe InDesign", and "Resolves an issue where email messages couldn’t be deleted from Yahoo accounts in Mail". So if you did set a hint, then if anyone has had physical access to your computer after High Sierra was installed it might be wise to investigate changing the disk encryption password.
#MAC KEYCHAIN ACCESS VULNERABILITY PASSWORD#
If we're reading that correctly, it means that someone asking for the password hint was actually shown the password instead. This was addressed by clearing hint storage if the hint was the password, and by improving the logic for storing hints." The update also addresses another password-related issue in High Sierra: "If a hint was set in Disk Utility when creating an APFS encrypted volume, the password was stored as the hint.
This was addressed by requiring the user password when prompting for keychain access." The issue is described thus: "A method existed for applications to bypass the keychain access prompt with a synthetic click. At least it wasn't remotely exploitable, but over the years some Mac users have been taken in by various Trojans, so there was a practical route for exploiting the vulnerability.Īpple released macOS High Sierra 10.13 Supplemental Update overnight to patch the vulnerability, crediting Wardle as the discoverer. Just before High Sierra was released, security researcher Patrick Wardle disclosed the existence of a vulnerability that allowed an application to extract in plaintext form all the passwords stored in a keychain.ĭespite Wardle's detailed private notification, Apple went ahead and released High Sierra with this vulnerability.
