Recently fileless malware is being discovered in computers across the world. What makes this so hard to detect is that it does not have a file or "artifact" on the computer to be found by antivirus software. Because it does not have to write anything to a computer, it can also run on any operating system, including unix.
So what are these programs mostly doing? they are executing scripts that encrypt their traffic, and farming clicks.
They are not keylogging, they are not configuring ports, they are farming clicks.
This raises tons of questions: Is it more profitable for a cybercriminal to farm clicks than do industrial espionage? Are the companies deliberately putting this on their computers, pretending to be hacked, then making extra cash on the side to change the narrative?
We left reddit because of the vote manipulation. We see all the bot twitter posts, but we never asked where they came from. We assumed it was from china, but if a shareholder where to sue twitter or reddit over paid vote manipulation, then the click farms in china would easily be discovered.
With the discovery of the file less malware thanks to the leaked NSA tools, we now have a more disturbing picture: Many computers are compromised, and are running hard to find botnets that solely generate site traffic and manipulate online marketing.

my recommendation is to run firefox or brave in firejail with apparmor. if you set up firejail with the overlay function, nothing is written to the disk and the program has no idea it has been jailed.

This was on multiple corporate networks: on unix AND linux machines.
We think FIN7 made it, because the new diagnostic tools think it was installed around April-May, around the same time they where fucking with chipotle and other companies.

Sounds like kovter and not fin7. Hashes, details, persistence mechanisms?

From what i understand, in one instance it was running powershell scripts that it read off of a text file.
It also had scripts that worked on other operating systems in other text files as well.
