Another day, another important security update for WordPress. Oh boy.

#2078 Satan ransomware: old name, new business model
Last month, we received a few queries asking about a strain of ransomware going by the name of Satan.

Those queries were along the lines of, “What do you detect it as?”

The simple answer is Troj/Ransom-ECZ, which is what we replied back then, but there’s a backstory to the Satan malware family that we thought was worth covering, too.

Cybercriminals have long used themes like the devil, the occult and what you might rather loosely call “the dark arts” as inspiration for malware names: Dark Avenger, Necropolis, Mydoom, Natas (which is Satan backwards) and SatanBug are just a few examples

But there’s one aspect of the Satan ransomware that isn’t old-school, and that’s what we’re looking at in this article: its business model.
#2077 Don’t let WikiLeaks scare you off of Signal and other encrypted chat apps
Of all the revelations to come out of the 9,000-page data dump of CIA hacking tools, one of the most explosive is the possibility that the spy agency can compromise Signal, WhatsApp, and other encrypted chat apps. If you use those apps, let’s be perfectly clear: Nothing in the WikiLeaks docs says the CIA can do that.

A close reading of the descriptions of mobile hacking outlined in the documents released by WikiLeaks shows that the CIA has not yet cracked those invaluable encryption tools.
#2076 WikiLeaks claims CIA could turn Samsung Smart TVs into listening devices
The CIA has developed a hacking tool named Weeping Angel that can turn Samsung smart TVs into covert listening devices.

This information came to the public's attention after WikiLeaks dumped today a treasure trove of documents, codenamed Vault 7, which the organization claims were taken from a "high-security network situated inside the CIA's Center for Cyber Intelligence."

The first part of the leak included only documentation files for hacking tools, exploits, zero-days, and malware, but no actual hacking tools. In total, WikiLeaks leaked 8,761 files, among which one stood out among the most.
