Apple issues Mac App Store patch for XARA exploits as additional fixes are ‘in progress’

A cross application resource attack (XARA) that researchers at Indiana University, Georgia Tech and China’s Peking University publicized last week seems to have been partially addressed as Apple issued a server-side fix on the Mac App Store to block malicious apps and secure app data.

Additional fixes are in the works for the XARA exploits on both iOS and OS X, a company spokesperson told iMore. XARA exploits allow malicious apps to steal iCloud credentials of a user, access private data in apps like 1Password and Evernote, hijack their iCloud Keychain passwords and more.
