What is Cyspt?

Cyspt is a ransomware-type virus discovered by MalwareHunterTeam. Research shows that this ransomware is likely to be a new variant of another virus called AresCrypt. Following successful infiltration, Cyspt encrypts most stored files and appends filenames with the ".OOFNIK" extension. For instance, "sample.jpg" is renamed to "sample.jpg", and so on. Immediately after encryption, Cyspt opens a pop-op window containing a ransom-demand message.

The pop-up window contains a message stating that data has been encrypted and can only be restored with the help of Cyspt's developers. Unfortunately, this information is accurate. It is currently not known which cryptography (symmetric or asymmetric) Cyspt uses to encrypt data, however, in any case, decryption requires a unique key generated individually for each victim. All keys are stored on a remote server controlled by cyber criminals. Restoring data without the key is impossible. Therefore, victims are forced to pay a ransom in exchange for decryption. The cost is $40 and must be paid in the Bitcoin cryptocurrency. In most cases, cyber criminals demand $500-1500. As compared to other ransomware, Cyspt's cost of decryption is rather low, however, users are encouraged to pay the ransom within 24 hours after encryption, otherwise the cost will double. After 72 hours, decryption supposedly becomes impossible (criminals will probably delete the keys). Despite this, we strongly advise you to ignore all requests to submit payments. Research shows that ransomware developers often ignore victims, once payments are submitted. Therefore, victims send money and receive nothing in return. They simply end up supporting cyber criminals' malicious businesses. Unfortunately, there are no tools capable of cracking Cyspt encryption and restoring data free of charge. The only solution is to restore everything from a backup.

The internet is full of ransomware-type viruses similar to Cyspt. The list of examples includes (but is not limited to) Gorgon, GEFEST 3.0, XCry, and .vaca. As with Cyspt, these viruses also encrypt data and make ransom demands - most ransomware has identical behavior. These viruses typically have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most employ RSA, AES, and/or other similar cryptographies that generate unique decryption keys. Therefore, unless the virus is still in development or has certain bugs/flaws, manual decryption without the involvement of the developers (not recommended) is impossible. To prevent data loss, we strongly advise you to maintain regular data backups and store them on remote servers or external storage devices. Locally-stored backups are encrypted with regular data.

How did ransomware infect my computer?

It is currently not known exactly how cyber criminals promote Cyspt. In most cases, however, ransomware-type viruses are distributed using spam email campaigns, unofficial software download sources, fake software update tools, software cracks, and trojans. Cyber criminals send spam emails that contains malicious attachments and deceptive messages, encouraging users to open attached links/files. Opening them typically results in malware infiltration. Third party software download sources (P2P networks, free file hosting websites, freeware download sites, etc.) present malicious executables as legitimate software, thereby tricking users into downloading and installing viruses. Fake updaters infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. Software 'cracks' are also used to proliferate malware - users often hope to bypass software activation, however, rather than doing so, they infect their computers with high-risk viruses. Trojans are malicious applications that, once infiltrated, cause so-called "chain infections". Therefore, they download and install additional software into the system.

Threat Summary:
NameCyspt 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 Cyspt virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

To prevent this situation, be very cautious when browsing the internet and downloading, installing, and updating software. Think twice before opening email attachments. Files/links that are irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. Furthermore, download software from official sources only, using direct download links, since third party download/installation tools are often used to proliferate viruses. The same rule applies to software updates. It is important to keep installed programs up-to-date, however, this should be achieved only through implemented functions or tools provided by the official developer. Never use software cracking tools, since using pirated software is considered a cyber crime and you also risk infecting your computer. Have a reputable anti-virus/anti-spyware suite installed and running at all times - these tools can detect and eliminate malware before it does any harm. If your computer is already infected with Cyspt, 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 Cyspt 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 Cyspt 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 Cyspt 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 Cyspt, 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 Cyspt 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.
