In response to purported CIA documents released by WikiLeaks, Apple said late Tuesday that its "initial analysis indicates that many of the issues leaked today were already patched in the latest iOS, we will continue work to rapidly address any identified vulnerabilities."

The leaked documents include thousands of pages detailing CIA hacking tools and methods that allegedly give the agency access to, among other tech devices, iPhones and Android phones, Samsung TVs, Wi-Fi networks, and Skype.

Despite initial confusing reports, the leaked documents don't contain information about the CIA's ability to break the encryption protocols used by messaging apps like Signal and WhatsApp. Instead, the released documents cover the CIA's ability to gain control of a device.

Open Whisper Systems, developer of Signal and its encryption protocol, said on Twitter: "The CIA/Wikileaks story today is about getting malware onto phones, none of the exploits are in Signal or break Signal Protocol encryption."

What should you do? Probably the best advice comes from Apple in its statement: "We always urge customers to download the latest iOS to make sure they have the most recent security updates."
