WikiLeaks said on Thursday morning it will release new documents it claims are from the Central Intelligence Agency which show the CIA had the capability to bug iPhones and Macs even if their operating systems have been deleted and replaced. From a report on Motherboard: "These documents explain the techniques used by CIA to gain 'persistenc'' on Apple Mac devices, including Macs and iPhones and demonstrate their use of EFI/UEFI and firmware malware," WikiLeaks stated in a press release. EFI and UEFI is the core firmware for Macs, the Mac equivalent to the Bios for PCs. By targeting the UEFI, hackers can compromise Macs and the infection persists even after the operating system is re-installed. The documents are mostly from last decade, except a couple that are dated 2012 and 2013. While the documents are somewhat dated at this point, they show how the CIA was perhaps ahead of the curve in finding new ways to hacking and compromising Macs, according to Pedro Vilaca, a security researcher who's been studying Apple computers for years. Judging from the documents, Vilaca told Motherboard in an online chat, it "looks like CIA were very early adopters of attacks on EFI."
