What is AnoymouS ransomware?

.AnonymouS virus – HiddenTear-based ransomware built for money extortion

AnoymouS ransomwareAnoymouS ransomware is a data locking malware that encrypts files and holds them hostage until ransom is paid

On October 23, 2020, new malware has arisen – AnonymouS ransomware. Like most ransomware, this one also infects victims' computer systems, encrypts all personal files, and demands a ransom to unlock their data. After encryption is done, all non-system files receive a file extension .AnonymouS, hence the name of the virus. The malware lands on the users' system via an executive file (.exe) – GTA V Setup.exe, although other samples might be using different names. It is also became apparent that the virus stems from one of the most prominent open-source ransomware known as Hidden Tear.

NAME AnonymouS
CLASIFICATION Malware, Ransomware, Cryptoware
RANSOM NOTE Message_Important.txt appears in affected folders. The text file contains ransom details in two languages – French and English.
DISTRIBUTION Spam emails and their content, torrent websites
INFECTION AFTERMATH Victims' files are encrypted and receive a new file extension – .AnonymouS, rendering the files inaccessible
REMOVAL STEPS To remove malware infection from your computer, you should scan your machine with anti-malware. If needed, access Safe Mode with Networking – we explain how below
SYSTEM FIX Ransomware can pose a significant danger not only to personal but also system files. If your computer is crashing and experiencing other stability issues, you can attempt to fix them with FortectIntego or other repair software

Users find text files (“Message_Important.txt”) in contaminated folders with a ransom demanding message inside (see the whole message below this paragraph). It's presented in two languages – French and English. Perpetrators define that users' data was encrypted using two cryptographic algorithms – RSA-2048 and AES-128.[1] Unlike in most ransom notes, the cybercriminals behind the .AnonymouS virus aren't warning the victims not to try and alter the files by renaming them or trying to decrypt with third party tools.

The developers just tell that the decryption is only possible with their “private key and decryption program.” Then they're presenting the instructions on how to pay the ransom. As always, the cybercriminals cannot be trusted, so we strongly advise you not to meet their demands, because usually, the victims not only lose their data but their money too.

Ransom note in the Message_Important.txt reads as follows:


1) French Version :

  • Malwarebytes – Ransom.HiddenTear
  • Panda – Trj/GdSda.A
  • Symantec – Ransom.HiddenTear!g1

AnoymouS ransomware encrypted filesAnoymouS ransomware prevents all access to the personal files

We strongly advise you to use SpyHunter 5Combo Cleaner for detection and FortectIntego for system restoration after the .AnonymouS ransomware removal is completed. Otherwise, your PC might suffer from various crashes, errors, BSODs,[2] and other issues post-termination.

Keep in mind that you should copy all the encrypted files before you remove AnonymouS ransomware if you have no backups to restore data from. Otherwise, you might permanently damage files, and they might become corrupted due to malware elimination of the usage of third-party tools.

Ransomware distribution methods

Malware spreads in many different ways – file-sharing platforms, spam emails,[3] to name just a few. Instead of downloading what the user thought he was getting, he might obtain some mischievous software from the file-sharing platforms without knowing about it. People should always download software only from reliable sources, e.g., from the developers.

While conducting a spam campaign, cybercriminals send out thousands of infected emails to computer users all over the world. The emails might look like an official letter from your company, your bank, etc., but beware of the attachments and unnatural looking links. The attachments might contain malware that would attack your data by encrypting or stealing it. And one might never know what you could find at the other end of the phony link, but in most cases – some sort of virus.

Recommended AnonymouS ransomware removal tools

To prevent the criminals from success in their line of work, firstly it is recommended to use powerful antivirus software (such as SpyHunter 5Combo Cleaner or Malwarebytes) and keep it updated at all times. To add more security to your data – keep backups of it in separate locations, such as the cloud, servers, removable drives.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
