What is Crypted034?

Discovered by Racco42, Crypted034 is a new variant of Scarab ransomware. After successful infiltration, Crypted034 encrypts data and renames it by generating a random filename and adding the ".crypted034" extension to each affected file. For instance, "sample.jpg" becomes "fhs40-45.crypted034", etc. Once encrypted, files become unusable and indistinguishable. Furthermore, this infection blocks Task Manager so that the encryption process cannot be terminated.  It also places the "HOW TO RECOVER ENCRYPTED FILES.TXT" text file, a ransom-demand message, in every folder that contains encrypted files.

According to the information provided in the ransom demand message, this virus has encrypted files due to 'security problems' with the computer. An ID number is given to identify yourself when contacting Crypted034 developers via one of the email addresses provided (dou876sh@tuta.io or dou876sh@mail.ee). The exact ransom amount due is unknown, however, payment in Bitcoins is stipulated. The cost supposedly depends on how quickly the ransom demands are met. Crypted034 ransomware developers offer free decryption of up to three files as a 'guarantee' that they can be trusted. The files must be no larger than 10MB, non-archived, and should not contain valuable information (databases, backups, large excel sheets, etc.). Victims of this ransomware-type virus are also urged not to rename or try to decrypt files using third party software. Apparently, these actions might increase the cost of decryption or lead to permanent data loss. Note that most ransomware developers (and other cyber criminals) cannot be trusted - they often ignore victims and provide none of the promised decryption keys or tools (even if their demands to pay the ransom are met). Unfortunately, at time of writing, there were no tools capable of decrypting Crypted034-encrypted files free of charge. The only free solution at the moment is to restore them using an existing backup.

There are many examples of ransomware-type viruses, including Bear, BlackHat, and Epoblockl. Most infections of this type are very similar, encrypt files and make ransom demands. The main differences are size of ransom and the cryptography algorithm used to decrypt files. It is not known whether Crypted034 developers use symmetric or asymmetric cryptography. In any case, a unique decryption key is generated for each victim. All keys are stored on a remote server controlled by cyber criminals. In this way, they can blackmail victims for release of the keys. To prevent future data loss, maintain regular data backups and store them on unplugged devices or remote servers.

How did ransomware infect my computer?

The exact method used to proliferate Crypted034 ransomware is not known, however, developers are likely to proliferate it using spam email campaigns, trojans, fake software update tools, and untrustworthy software download sources. Cyber criminals use spam campaigns to proliferate various infections using malicious attachments. Typically, they attach a Microsoft Office document, archive file, PDF, executable, or other file to an email sent to many recipients in the hope that some will download and open it. Once opened, these attachments download and install viruses. Trojans, on the other hand, must already be installed. When installed, they cause chain infections - these malicious programs proliferate other viruses. Fake software updaters cause infections by downloading and installing viruses rather than the updates, or exploiting outdated software bugs or flaws. Various free file hosting and freeware download websites, peer-to-peer networks (for instance, eMule, torrent clients, etc.), and other third party software download sources are used by cyber criminals who present infected files as legitimate. In this way, they trick people into installing viruses.

Free scanner checks if your computer is infected. To remove malware, you have to purchase the full version of Spyhunter.

How to protect yourself from ransomware infections?

Manage emails carefully, and avoid opening attachments or links in received from unknown/suspicious addresses. If you suspect that an email is irrelevant, do not open any included attachment or click the link. Download software using direct links, trustworthy and official sources only. Avoid using third party downloaders, installers - these sources are used to proliferate rogue applications that might cause computer infections or other problems. Update software using tools or implemented functions that are provided by official software developers only. We strongly advise you not to use third party updaters. Finally, have reputable anti-virus/anti-spyware installed and keep it enabled at all times - this software can stop infections before they proliferate. If your computer is already infected with Crypted034, 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 Crypted034 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 Crypted034 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 Crypted034 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.

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 Crypted034, 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 Crypted034 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.
