Evil Locker ransomware removal instructions

What is Evil Locker?

Evil Locker is a ransomware-type virus discovered by malware security researcher, Jakub Kroustek. After stealthily infiltrating the system, Evil Locker encrypts most stored files and appends filenames with the ".[evil@cock.lu].EVIL" extension. For example, "sample.jpg" is renamed to "sample.jpg.[evil@cock.lu].EVIL". Once compromised, data immediately becomes unusable. Following successful encryption, Evil Locker generates a text file ("!_HOW_RECOVERY_FILES_!.txt") and places a copy in all existing folders.

As with most ransomware, Evil Locker's text file contains a message stating that data is encrypted and can only be restored using a certain decryption tool. To receive it, victims must contact Evil Locker's developers via an email address provided. Furthermore, they are permitted to attach up to three encrypted files, which are restored and returned as a 'guarantee' that decryption is possible. The text file gives no additional information and, therefore, it is currently unknown which cryptography (symmetric or asymmetric) Evil Locker uses. Nevertheless, decryption requires a unique key (generated individually for each victim). All keys are stored on a remote server controlled by Evil Locker's developers. To receive the key (or rather, a decryption tool with key embedded within), victims must pay a ransom. All information regarding payment is provided via the email. Therefore, we cannot ascertain the exact cost. In most cases, however, the size of ransoms fluctuates between $500 and $1500 in a type of cryptocurrency (Bitcoins, Monero, or other). No matter what the cost, do not pay. Cyber criminals often ignore victims after payments are submitted. Therefore, these people can never be trusted - never attempt to contact them and certainly do not pay any ransoms. Unfortunately, there are no tools capable of cracking Evil Locker's encryption and restoring data free of charge. The only solution is to restore everything from a backup.

Evil Locker is virtually identical to ANIMUS, BitPaymer, Nozelesn, and dozens of other ransomware-type viruses. All are developed by different cyber criminals, and yet their behavior is identical - all encrypt data and make ransom demands. There are just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Most of these viruses employ algorithms such as RSA, AES, and others, that generate unique decryption keys. Therefore, unless the virus is still in development or has certain bugs/flaws, restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Ransomware is one of the main reasons why you should maintain regular data backups, however, store them on an unplugged storage device (Flash drive, external hard drive, or other) or remote server (i.e., Cloud), otherwise backups are encrypted with regular data.

How did ransomware infect my computer?

Ransomware is typically proliferated using spam emails (infectious attachments), trojans, fake software updaters, P2P networks (torrents, eMule, etc.), and third party software download sources (freeware download websites, free file hosting sites, etc.) Malicious attachments are usually delivered in the form of JavaScript files or MS Office documents. Once opened, these files run scripts that stealthily download and install malware. Trojans open "backdoors" for other malware to infiltrate the system. Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. P2P networks and other unofficial download sources present malicious executables as legitimate software, thereby tricking users into downloading and installing viruses.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing/updating software. Carefully analyze all received email attachments. Files that seem irrelevant or have been received from a suspicious/unrecognizable email address should never be opened. Download your programs from official sources only, using direct download links. Third party download/installation tools should never be used, since developers monetize them by promoting rogue applications. In addition, keep installed apps up-to-date. To achieve this, however, use implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also essential. If your computer is already infected with Evil Locker, 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 Evil Locker 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 Evil Locker 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 Evil Locker 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 Evil Locker, 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 Evil Locker 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.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
