What is Supportfiless24?

Supportfiless24 is a high-risk virus, a variant of Scarab ransomware. It is designed to infect systems and encrypt stored data so that affected people cannot use it until ransom demands are met. Supportfiless24 ransomware encrypts files using the RSA-2048 cryptography algorithm. It changes the encrypted filenames by applying a random sequence of letters, numbers, and symbols, and adding the ".supportfiless24@protonmail.ch" extension. For example, after encryption "sample.jpg" might be renamed a filename such as "9UXF5ee0ct+=lA.supportfiless24@protonmail.ch". Therefore, encrypted files become unusable and indistinguishable. This virus also places the "HOW TO RECOVER ENCRYPTED FILES-supportfiless24@protonmail.ch.txt" text file in each folder containing encrypted files.

According to the message in the text file, the victim's files are encrypted and only cyber criminals who developed this virus can decrypt them. To decrypt their files, users who are affected are encouraged to contact Supportfiless24 developers via the email address supportfiless24@protonmail.ch provided. If there is no response, the fastsupport@xmpp.jp email address or Jabber can be used. There is no information regarding the ransom amount, however, it is likely that this information is provided when cyber criminals are contacted. Supportfiless24 developers urge victims to contact them to pay the ransom within two days, otherwise they will not provide decryption keys required to unlock the encrypted files. Do not contact them - most cyber criminals ignore victims whether victims meet ransom demands or not. Unfortunately, there are no tools capable of cracking the encryption free of charge. The only way to retrieve files is to use an existing backup and restore them from there.

Supportfiless24 ransomware is similar to many other viruses of this type, such as Ox4444, Dharma-tron, Maria, etc. All of these viruses serve an identical purpose: to encrypt files and keep them locked until the ransom is paid. The ransom sum and cryptography algorithm used are the only differences. Generally, it is impossible to decrypt files manually, unless the virus contains bugs or is in the development stage. Therefore, ransomware victims are encouraged to contact cyber criminals to recover their files (this is not recommended). Therefore, maintain regular backups and store them on a remote server or unplugged device (otherwise, the backups might also be encrypted).

How did ransomware infect my computer?

It is not known exactly how cyber criminals proliferate the Supportfiless24 ransomware-type virus, however, there are several common methods including trojans, spam email campaigns, untrustworthy third party software downloaders, and fake software updating tools. Trojans are malicious programs that, once installed, proliferate other viruses, including ransomware-type viruses. Spam campaigns are used by cyber criminals who send emails containing malicious attachments. The point of these campaigns is to trick people into opening the attachment that downloads/installs malware. The attachments are usually Microsoft Office documents, executable files, archive files, and so on. By using third party software download sources, cyber criminals present malicious executables as legitimate files and trick people into installing malware. Some examples of untrustworthy download sources are peer-to-peer (P2P) networks, torrents, free file hosting websites, freeware download sites, and so on. Fake software update tools usually infect computers by downloading malicious software rather than the promised updates, or exploiting outdated software bugs/flaws.

How to protect yourself from ransomware infections?

Be careful when opening attachments or links that are presented in emails received from unknown/suspicious addresses. If you believe that the attachment or link is irrelevant, do not open it. Choose your software download sources carefully - use official, trustworthy sources and direct links only. Do not use third party downloaders such as torrents, eMule, dubious websites, and so on - these channels are used to proliferate rogue applications that might cause computer infections or other issues. It is important to keep software updated, but use tools or implemented functions that are provided by official developers only. To prevent computer infections, have reputable anti-virus/anti-spyware software installed and enabled. If your computer is already infected with Supportfiless24, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 Supportfiless24 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 Supportfiless24 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 Supportfiless24 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 Supportfiless24, 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 Supportfiless24 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.
