TL;DR on the latest round of Wikileaks:
Literally nothing you do is safe from the CIA. There are numerous full-on spyware suites developed by them, mostly for iOS and Windows, but also targeting Android, Linux, OS X, and Solaris.
Apps thought to be secure (Telegram with encryption enabled, WhatsApp, Signal) were compromised (EDIT: This is incorrect, although the devices that these were on were compromsied) as well, as were a host of other devices (ie smart TVs).
THIS DOES NOT PERTAIN ONLY TO AMERICANS.
If you live in a Schengen area country, your country likely hosts several CIA backed cyberwar experts. They came in via the US consulate in Frankfurt. If you don’t, you likely do as well, but I can’t find anything without sifting through the files myself.
“I have nothing to hide, why does this matter?”: Because there are now multiple thousand “zero hour”- ie “developers get zero hours to fix”- vulnerabilities floating around that no one had any idea existed. The vulnerabilities themselves weren’t leaked, but it’s the fact that someone knew about these and didn’t say.
EDIT: These look to mostly be older, already used bugs, see this post
I hate to make this kinda clickbait-y thing, but this is honest to God one of the most important leaks in history. Our response to this is pretty much going to be life or death for privacy in the developed world. Be loud about this, be annoying about this, and do not shut up about this. Please reblog this and other posts relating to it.
