What is PC-FunHACKED!?

PC-FunHACKED! is one of many ransomware-type programs online. This example is a new variant of Jigsaw ransomware and was discovered by Michael Gillespie. Like most programs of this type, it is designed to encrypt data and make ransom demands. It displays a ransom message within a pop-up window, generates an "Address.txt" text file, which contains a Bitcoin wallet address, and a random "dr" file. In the version we tested, PC-FunHACKED! ransomware did not change the filename extension of encrypted files, however, in other cases, it has added the ".PC-FunHACKED!-Hello" extension tens of times. For example, "1.jpg" might be renamed to "1.jpg.PC-FunHACKED!-Hello.PC-FunHACKED!-Hello.PC-FunHACKED!-Hello...", and so on.

According to the ransom message displayed in the pop-up window, the program encrypted all data and will delete everything unless victims comply. It states that some files will be deleted an hour after encryption (the pop-up window includes a countdown timer). According to these cyber criminals, files are deleted permanently and the number of deleted files increases daily. For example, on the first day it will delete just a few, then one hundred the next day, and so on. According to PC-FunHACKED!'s developers, turning off the computer will result in the immediate loss of 1000 files. To prevent data loss, users are encouraged to transfer $100 (equivalent in Bitcoins) to a wallet address provided. They also mention that only they can provide the tool required for decryption. Unfortunately, this is probably accurate. Most ransomware developers use cryptography algorithms (symmetric or asymmetric) that generate unique decryption keys. Cyber criminals store them on remote servers accessible only by them. In this way, they can blackmail victims and make ransom demands. There are no tools currently capable of decrypting PC-FunHACKED!'s encryption free of charge. If your computer is infected with this ransomware, the best (free) way to retrieve files is to use an existing data backup and restore everything from there.

As mentioned, there are many ransomware-type programs. Some examples of other infections of this type are Dharma-Gif, GandCrab 5.1, and Obfuscated. Most ransomware infections are very similar: they encrypt data and blackmail victims by making ransom demands (to purchase a decryption tool). Common differences are cryptography algorithm used to encrypt data and ransom amount (cost of decryption). Unfortunately, most cyber criminals use cryptographies that are impossible to 'crack', unless the program is still in development or contains bugs/flaws. To avoid data loss, maintain regular backups and store them on remote servers or unplugged storage devices.

How did ransomware infect my computer?

The specific method used to proliferate PC-FunHACKED! ransomware is unknown, however, cyber criminals often use spam email campaigns, fake software updaters, dubious software download sources, and Trojans. Spam campaigns infect computers through malicious attachments, which are often Microsoft Office documents, archive files such as ZIP, RAR, and so on, executable files, PDF documents, and various other files. The main goal is to trick people into opening these malicious attachments. Once opened, they cause download and installation of malware. Fake software updaters infect systems by exploiting flaws/bugs of outdated software or by downloading and installing malicious programs rather than the promised updates. Untrustworthy sources such as P2P (peer-to-peer) networks (torrents, eMule etc.), third party downloaders/installers, freeware download websites, free file hosting web pages and other similar channels are used by cyber criminals who present computer infections as legitimate files. Trojans are programs that cause chain infections. If a trojan is installed, it is likely to proliferate (download and install) other infections.

How to protect yourself from ransomware infections?

To prevent computer infection with ransomware-type and other malicious programs, be careful while downloading, installing, updating software, and opening attachments (or web links) that are included in received emails. Avoid opening attachments and websites if they are presented in emails received from unknown, suspicious addresses. These are usually irrelevant but presented as 'important'. Use official and trustworthy sources when downloading software. Unofficial websites, third party downloaders and installers, and other dubious tools should not be used. Update your software using implemented functions or tools provided by the official software developers only. Do not use other tools. Have reputable anti-virus/anti-spyware software installed (and enabled). This software can detect and remove computer infections before they can do any damage. If your computer is already infected with PC-FunHACKED!, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Text presented in PC-FunHACKED! ransomware pop-up window:

I want to play a game with you. Let me explain the rules:
Your personal files are being deleted. Your photos, videos, documents, etc...
But don't worry! It will only happen if you don't comply.
However, I've already encrypted your personal files, so you cannot access them.

Every hour I select some of them to delete permanently,
therefore I won't be able to access them, either.
Are you familiar with the concept of exponential growth? Let me help you out.
It starts out slowly then increases rapidly.
During the first 24 hour you will only lose a few files,
the second day a few hundreds, the third day a few thousand, and so on.

If you turn off your computer or try to close me, when I start next time
you will get 1000 files deleted as a punishment.
Yes you will want me to start next time, since I am the only one that
is capable to decrypt your personal data for you.

Now, let's start and enjoy our little game together!

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the PC-FunHACKED! ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining PC-FunHACKED! ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of PC-FunHACKED! are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by PC-FunHACKED!, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as PC-FunHACKED! ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
