FUNNY ransomware removal instructions

What is FUNNY?

Discovered by Jakub Kroustek, FUNNY is another ransomware virus belonging to the Dharma malware family. When a computer is infected with this virus, most files are encrypted and renamed with the ".FUNNY" extension added. For instance, "1.jpg" is renamed to "1.jpg.FUNNY". All encrypted files become unusable. FUNNY ransomware displays a ransom demand pop-up window and places the "FILES ENCRYPTED.txt" text file on the desktop.

If your computer is infected with the FUNNY ransomware-type virus, you will encounter a pop-up window with a message informing you that all files have been encrypted due to a 'security problem' with your computer. Cyber criminals provide an email address that should supposedly be used to contact them to restore the encrypted files. It is not known which cryptography algorithm (symmetric or asymmetric) is used, however, it is likely that the files can only be restored using a specific decryption key generated individually for each victim. To receive this key, victims are encouraged to pay a ransom (in Bitcoins). The size of the ransom is unknown, however, according to FUNNY's developers, this depends on how quickly they are contacted via the email address. To gain the victim's trust, they offer free decryption of one file, however, they advise against trying to decrypt locked files using the help of any third parties. According to FUNNY ransomware developers, these attempts will only increase the cost of decryption or cause data loss. Note that cyber criminals cannot be trusted. Typically, they continue to ignore victims even if they meet their demands/pay the ransom. Paying the ransom does not deliver any positive result and users are scammed. Do not make any payments. Unfortunately, there are no tools that are capable of cracking FUNNY encryption (restoring data) free of charge. The best option in this case is to restore lost files using an existing backup.

There are many similar or identical ransomware-type viruses. Examples include Vanss, GusCrypter, and Betta. They might be developed by different cyber criminals and have different names, but most have similar behavior. Typically, they encrypt data and make ransom demands. The main differences are size of a ransom and type of encryption algorithm used to lock the files. The cryptographies used generate individual (unique) decryption keys, and thus manual decryption (without involvement of cyber criminals) is virtually impossible, unless the virus is not fully developed or contains bugs/flaws. The existence of these ransomware-type viruses make a strong case to maintain regular backups. These should be stored on remote servers and/or unplugged devices, otherwise cyber criminals might be able to encrypt them with other regular data.

How did ransomware infect my computer?

The exact method used to promote FUNNY ransomware is unknown, however, in most cases, these viruses are distributed using spam email campaigns, trojans, fake software updaters, and various untrustworthy/unofficial software download sources. Spam email campaigns contain malicious attachments, usually Microsoft Office document files. Once opened, these attachments infect computers by downloading and installing malware. Another way systems become infected by malware is through trojans. Trojans are viruses used to proliferate other viruses - so-called chain infections. Unofficial software download sources such as P2P (peer-to-peer) networks, eMule, torrents, and so on usually present malicious software as legitimate. By using these channels, cyber criminals trick users into downloading and installing malware. Another common way to proliferate these viruses are via fake software updaters. They exploit bugs and flaws of outdated software, or download (and install) malware rather than software updates and fixes.

Threat Summary:
NameFUNNY virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

To eliminate FUNNY virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Regular users are often responsible for computer infections. To keep computers safe from these infections, be cautious when browsing the web and downloading, installing, or updating software. The links or attachments presented in emails sent from unknown/suspicious addresses should never be opened or clicked. Software should be downloaded using official and trustworthy sources only, but not via third party downloaders, installers, and so on. Some of these include rogue applications that might cause computer infections. Installed software should be updated, but only using implemented functions or tools provided by official developers. Finally, have reputable anti-virus/anti-spyware software installed and to keep it enabled at all times. If your computer is already infected with FUNNY, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 FUNNY 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 FUNNY 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 FUNNY 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 FUNNY, 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 FUNNY 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.
