The REvil ransomware gang has removed Apple’s schematics from their data leak site. Earlier this month, the gang conducted an attack on Quanta, a Taiwan-based original design manufacturer (ODM) that helps manufacture the Apple Watch, Macbook Air, and the Apple Macbook Pro. After not receiving a ransom payment, REvil began posting data for Apple Macbooks on the site. As part of this leak, the group warned Apple that they should buy back the data by May 1st or more data would be leaked.
