CryptFuck virus Removal Guide

What is CryptFuck ransomware virus?

CryptFuck ransomware makes fun of its victims

It seems that creativity of cyber criminals is simply endless. However, CryptFuck virus proves that they definitely know how to make nasty jokes, too. This malicious crypto-ransomware virus seems to be an improved version of FSociety virus since both viruses appear to be created by a person who loves Mr. Robot TV series. The virus encrypts all files that if finds on the computer system and plugged-in drives and also appends .URfucked file extensions to them. Then it creates and saves README_CRYPTFUCK.txt file, which is the ransom note. The ransom note includes such information:

You have been attacked by the CryptFuck RansomWare v [version]

[Identification keys here]
If you lose your identifier, any chance of getting back your data is flushed in the toilet!!
Keep in mind that you have 72 hours to perform the payment, after that, your encrypted password would be deleted permanently!
If your browser does not open any webpage, visit this page to learn how to get back your files:

As you can see, the ransomware author asks to access the payment site for details on how to decrypt the data. The virus asks to pay up within 72 hours; otherwise the “encrypted password” will be deleted for good. This offensively-named ransomware variant is just another virus that seeks to swindle money from computer users who do not have data backups and haven’t taken precautions to protect their computers from ransomware attack in the past. We encourage users not to pay the ransom and remove CryptFuck malware instead. The best way to carry out CryptFuck removal is to use a program capable of uninstalling numerous malware variants, for instance, you can use the FortectIntego program.

Consequences after CryptFuck ransomware attacks the computer

How did I get infected with this virus?

This malicious threat is based on EDA2 ransomware and spreads using typical ransomware distribution techniques. Just like any other ransomware-type virus, it is being distributed via malicious email campaigns and malvertising. You can install this malware by clicking on a malware-laden email attachment or a bogus advertisement online. To keep your computer protected, stay away from such content. Crooks put efforts into crafting professional-looking email messages, inviting users to see what’s attached to them or to open links included in the message. If the victim allows his/hers curiosity win, such malware can quickly activate itself once it gets into the computer system and corrupt victim’s data for good. We also highly recommend staying away from websites that keep showing advertisements urging to install some kind of software or update supposedly outdated Java or Adobe software. Judging from our experience, we can say that modified versions of such reputable software often include malicious attachments, trojans, ransomware executive files, and so on. It is a good idea to create data backups and move them to removable storage devices so that you can use them in case a ransomware attacks your computer.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
