Shortly after Wikileaks released a cache of documents revealing details on CIA programs aimed at hacking popular mobile operating systems such as Android, Chrome, and iOS, Google said that many of the vulnerabilities highlighted in the leak have already been fixed.

“As we’ve reviewed the documents, we’re confident that security updates and protections in both Chrome and Android already shield users from many of these alleged vulnerabilities,” said Heather Adkins, Google’s Director of Information Security and Privacy.

As for the remaining vulnerabilities, Adkins noted, “our analysis is ongoing and we will implement any further necessary protections.”

Apple also issued a similar statement: “While our initial analysis indicates that many of the issues leaked today were already patched in the latest iOS. Apple will continue work to rapidly address any identified vulnerabilities.”
