What is PRISM ransomware? And how does it execute its attack?

PRISM ransomware is a making a comeback as it was spotted recently in the web. It first emerged many years ago and is designed to lock an infected computer, preventing users from accessing their compromised computers. This dangerous ransomware threat also works as a scam and it’s named PRISM as it seems to come from the Reveton Trojan family.

PRISM ransomware contains a scamming message that presents false claims about illegitimate copyright, software usage and children pornography activities and for users to avoid prosecution, they have to pay a fine of $300 via MoneyPak within the given 48 hours. Once it infiltrates a system, PRISM ransomware drops several of its malicious components into system folders in order to execute its attack and keep it from getting detected by any program that might interfere with its attack. It also makes modifications in the Windows Registry to allow it to run on every system boot and achieve persistence. Shortly after the modifications are applied, it immediately locks the computer’s screen with an image that contains FBI’s logo and a message that states:

“NSA Internet Surveillance Program.

PRISM.

Computer Crime Prosecution Section.

Your Computer has been locked!

Your computer has been locked due to suspicions of illegal content downloading and distribution.

Your case can be classified as occasional/unmotivated, according to 17 (U.S Code)

Thus it may be closed without prosecution.

Your computer will be unblocked automatically.

In order to resolve the situation in an above-mentioned way you should pay a fine of $300 (MoneyPak)”
