WikiLeaks releases new #Vault7 documents on apparent CIA programme for hacking Apple products
New documents from WikiLeaks point to an apparent CIA programme to hack Apple's iPhones and Mac computers using techniques that users could not disable by resetting their devices.
The CIA has not commented on the authenticity of this and earlier WikiLeaks revelations, but has previously said it complies with a legal prohibition against electronic surveillance "targeting individuals here at home, including our fellow Americans".
The leaks on Thursday come about two weeks after WikiLeaks published thousands of alleged CIA documents describing hacking tools it said the US government employed to break into computers, mobile phones and even smart TVs from companies such as Apple, Google, Microsoft and Samsung.
The latest disclosures are much more focused and consist of just 12 documents, all involving Apple products.
The documents describe techniques for rewriting devices' firmware in ways that would maintain a hacker's access even if a user resets a phone or computer to factory settings.
Doing so wipes out all apps and the operating system and installs a clean version; it is an extreme measure sometimes used to deal with technical problems, but is also the sort of step that someone suspicious of surveillance might take when getting a brand new phone.
A December 2008 document describes NightSkies, a tool apparently designed to target the iPhone 3G; the document claims it can retrieve files such as contact lists and call logs and execute other commands.
WikiLeaks suggested in a press release that the "CIA has been infecting the iPhone supply chain of its targets since at least 2008".
However, the document describes only how to install the malware on a "factory fresh" version of the 3G - specifically, the iPhone 3G running the 2.1 version of Apple's operating system, both of which are now nine years old.
Johannes Ullrich, director of the Internet Storm Centre at the SANS Institute, said NightSkies might not even be a current project given that the document was last updated in 2008, while the leaks appear to have come in 2016.
Other documents released describe similar exploits for Mac computers.
One hides in the firmware of Apple's Thunderbolt-to-Ethernet adapter and requires someone to plug in that adapter to install the malware.
Another targets a specific Mac model, the MacBook Air with the Leopard version of the Mac OS system - current at the time, but now seven generations old.
Apple did not respond to a request for comment.
