Foop virus file extension – are your files encrypted with it? If so, then your system has been attacked by a severe crypto infection – another iteration of the infamous STOP ransomware. This article will provide you with instructions on what to do, once your files have been encrypted with the .foop extension.
Foop Virus
The Foop virus encrypts personal data via a strong encryption algorithm. Once this process is finished, you can’t operate with your files until they are decrypted. They all have the extension .foop appended to their names. At the end of the attack the Foop ransomware drops a ransom message file, _readme.txt, on the infected system to blackmail you to pay a ransom fee for the alleged decryption of their files.

Foop Ransomware Overview
Foop virus is part of the STOP ransomware family which has appeared on the malware scene before a few years. This last STOP/Djvu iteration acts in the same way as its predecessors Rezm, Lokd and Mmnn.
Soon after Foop ransomware virus is started on a computer system, it creates a bunch of malicious files that will support all subsequent operations. By executing these files in a strictly defined order, the threat evades the detection of all active security measures and passes through several attack stages.
Current ransomware variants are usually more sophisticated than older ones, and they can perform various malicious activities that seriously disrupt the operating system. To become persistent the Foop ransomware adds malicious values under specific registry keys. Such a key is the RUN registry key.
Once the Foop virus affects the key RUN, it can start its malicious files on each system reboot. Thus, the best advice we can give you is to check your system’s registries and clean malicious entries while also removing Foop ransomware from your system.
Long story short, the sole purpose of all malicious stages of the ransomware operation is the encryption of your files. For the encryption to take place, the Foop virus launches a built-in cipher module after it scans specific folders for certain file types typically utilized for storage of personal data.
Each time the module detects a target file, it applies changes that alter the original code of the file to encrypt it. Then the encrypted file receives the extension .foop and remains inaccessible until its code is reverted back to the original state.
Security researchers have managed to find weaknesses in its code and released a free decryption tool. However, at the moment, the free decryption tool does not support decryption of .foop files. As soon as we notice security researchers’ announcement about an update that supports the decryption of Foop ransomware, we will update this article with the latest information.
As for the distribution of the Foop virus, it is believed to be happening via malspam (malicious spam).
Malspam campaigns let cybercriminals reach a large userbase which in turn has proven to be efficient. Malicious emails usually contain malicious code hidden in commonly used file types, such as documents and archives attached to the email message. In most cases, such malicious emails pretend to be send by legitimate sources, such as largely known organizations and companies.
NOTE. You should know that files which should activate the Foop virus on Windows can be:
- Invoice coming from reputable sites, like PayPal, eBay, etc
- Document that appear to be sent from your bank
- An online order confirmation note
- Receipt for a purchase
- Tax bill
Once the encryption stage is finalized, the virus drops the _readme.txt ransom note, which should say the following:
ATTENTION!
Don’t worry, you can return all your files!
All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key.
