The data dump, which includes CIA documents dating back to 2012, highlights how agents were able to infect Apple devices if they could gain physical access to them.
Agents could allegedly gain access to a Mac's firmware, for example, by using an Ethernet adapter that plugged into the computer's Thunderbolt port. They could also compromise "factory fresh" iPhones, according to the documents.
An Apple spokesperson sent Business Insider the following statement:
"We have preliminarily assessed the Wikileaks disclosures from this morning. Based on our initial analysis, the alleged iPhone vulnerability affected iPhone 3G only and was fixed in 2009 when iPhone 3GS was released. Additionally, our preliminary assessment shows the alleged Mac vulnerabilities were previously fixed in all Macs launched after 2013.
"We have not negotiated with Wikileaks for any information. We have given them instructions to submit any information they wish through our normal process under our standard terms. Thus far, we have not received any information from them that isn't in the public domain. We are tireless defenders of our users' security and privacy, but we do not condone theft or coordinate with those that threaten to harm our users."
The documents are the latest to come out of the "Vault 7" documents from Wikileaks. The first batch of the documents claimed that the CIA could break into Samsung smart TVs and the iPhone.
