Getting caught viewing child porn is a huge deal and instantly makes you an outcast in most western countries. Cybercriminals have cooked up a new way to blackmail people out of their money, both inside and outside the office.
The ransomware family is called Revoyem (aka Dirty Decrypt) and uses the worst possible strategy to get people to pay up.
It starts at a porn site that you have landed on, either on purpose or by accident. Then you are redirected by a malicious ad to an actual child porn themed page with very disturbing images. But while you are there, your PC gets infected with the Styx malware dropper which downloads ransomware and your computer gets locked.
The lock screen again shows disturbing images and now accuses you of watching child porn and what the penalties are. However, here comes your friendly ransomware to the rescue. Just pay the fine and you will not be prosecuted. They tell you to use either MoneyPak or PaysafeCard.
The attack is seen in the U.S., Canada and several Western European countries, is translated for each territory and uses the correct government law enforcement agency as a threat. This looks very much like an Eastern European Cybermafia operation.
WHAT TO DO: In an office environment, call the helpdesk and they will treat this as malware and remove it. At the house, call the police and file a complaint. It is likely the Police already know about it. Then take the PC to an expert and get the malware removed.
And stay away from unsafe areas on the Internet like gambling and porn sites! Here is how the lock screen looks:
