What is SYSTEM FAILURE?

SYSTEM FAILURE is a high-risk ransomware infection discovered by Michael Gillespie. After successful infiltration, SYSTEM FAILURE encrypts most stored files and appends filenames with a random string  (e.g., "sample.jpg" might be renamed to a filename such as "sample.jpg.eB4wgUJ"). Encrypted data instantly becomes unusable. After successful encryption, SYSTEM FAILURE generates an HTML file ("DECRYPT-FILES.html") and stores a copy in every existing folder. Additionally, SYSTEM FAILURE ransomware changes the desktop wallpaper.

The new HTML file delivers a message stating that data is encrypted and that a unique decryption key is necessary to restore it. According to SYSTEM FAILURE's desktop wallpaper, data is encrypted using RSA-2048 - an asymmetric encryption algorithm. If this is the case, unique public (encryption) and private (decryption) keys are generated for each victim. Note that victims cannot access them, since developers store all keys on a remote server. The message states that, to receive their decryption key, each victim must pay a ransom, since restoring data without the private key is impossible. The cost is not specified - all details are provided after victims make contact with these people via an email address provided. Cyber criminals typically demand $500-$1500 in Bitcoins, Ethereum, Monero, DASH, or another cryptocurrency. Victims are also allowed to attach one selected file, which will supposedly be restored and returned as a 'guarantee' that decryption is possible and that these people can be trusted. Regardless of the cost, do not pay. Criminals often ignore victims, once payments are submitted. Therefore, they simply end up being scammed and their data remains encrypted. You should never attempt to contact these people or send any money. Unfortunately, SYSTEM FAILURE is undecryptable ransomware - there are no tools capable of cracking its encryption and restoring data free of charge. You can only restore everything from a backup, if one has been created.

SYSTEM FAILURE shares similarities with dozens of other ransomware-type infections such as yG, Qbtex, and Codnat. Most ransomware infections compromise data by encryption so that cyber criminals can make ransom demands for file recovery. In most cases, the only major differences are size of ransom and type of encryption algorithm used. The cryptographies used (e.g., RSA, AES, etc.) generate unique decryption keys. In such cases, manual decryption is impossible unless the virus is still in development or has certain bugs/flaws. Ransomware presents a strong case for maintaining regular backups, however, store them on a remote server or unplugged storage device, since locally stored backups are compromised together with regular data. We also recommend that you have multiple backup copies stored in different locations, in case the server/hardware is damaged.

How did ransomware infect my computer?

Ransomware infections are proliferated using spam email campaigns, third party software download sources, trojans, and fake software updaters/cracks. Spam campaigns are used to send hundreds of thousands of emails that contain malicious attachments (links/files), together with messages encouraging users to open them. The messages often present attachments as important documents (e.g., invoices, bills, receipts, etc.) in attempts to give the impression of legitimacy and trick users into opening them. Third party download sources are also used in a similar way. Criminals use peer-to-peer (P2P) networks, freeware download websites, free file hosting sites and other similar sources to present malicious executables as legitimate software. In this way, users are tricked into manually downloading and installing malware. Trojans are malicious applications that stealthily infiltrate computers and inject them with additional malware. Fake updaters infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than the /promised updates. Finally, fake software cracks have identical behavior as fake updaters. The purpose of cracking tools is to activate paid software free of charge, however, since criminals often use them to proliferate malware, users are much more likely to infect their computers than gain access to paid features. In summary, the main reasons for computer infections are poor knowledge and careless behavior.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, to prevent this situation, be very cautious when browsing the Internet, and downloading, installing and updating software. Handle received email attachments with care. Files/links that are irrelevant should never be opened. Attachments received from suspicious/unrecognizable email address should be ignored. Download software from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus these tools should never be used. Similar rules apply to software updates. Keeping installed applications and operating systems up-to-date is paramount. To achieve this, however, you should employ implemented functions or tools provided by the official developers. Be aware that software piracy is a cyber crime and the risk of infections is extremely high. Therefore, never attempt to crack installed applications. Having a reputable anti-virus/anti-spyware suite installed and running is also very important, since these tools can detect and eliminate malware before the system is harmed. If your computer is already infected with SYSTEM FAILURE, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

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 SYSTEM FAILURE 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 SYSTEM FAILURE 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 SYSTEM FAILURE 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 SYSTEM FAILURE, 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 SYSTEM FAILURE 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.
