The files consist mostly of notes and documentation on the CIA’s hack attack tools – very specific tools used when the agency focuses on a very specific target. These aren’t just hoovering up everyone’s data like the lazy old NSA – this is what a modern Bond’s “Q” would use to go after a special someone, or someones.
As in, probably not you.
The attacks focus on operating systems, not on apps themselves. That bit you read about the CIA cracking Signal and WhatsApp was false. What this all shows, interestingly, is that encryption on those apps is tight enough that even the CIA hasn’t been able to break them and needs to pop old versions of iOS just to read some ambassador’s uncreative sexts.
There is literally no surprise here. The ubiquity of large systems having exploitable bugs, and the implications of this, have been reported on for decades.
Perhaps the nonstop cycle of social-media outrage has given us collective amnesia. What’s old is new, and suddenly everyone is shocked to hear that there are 0-days in Windows and Android, and people are taking advantage of exploits. We all jump on a chair and lift our skirts and cry “rat!” because someone, somewhere, hasn’t taken our advice about what to do with vulnerabilities.
The irony is that the best way to avoid these kinds of attacks is to update your system software when you’re supposed to, don’t get phished and try not to become a CIA target by, say, committing treason. Oh, and don’t stop using reputable encrypted apps. Especially not because some guy with a hard-on for the CIA told the press the apps were compromised.
