Cradle ransomware removal instructions

What is Cradle?

Cradle is a ransomware-type virus discovered by malware security researcher, Michael Gillespie. Once infiltrated, Cradle encrypts various files and appends the ".cradle" extension to the name of each encrypted file. For instance, "sample.jpg" is renamed to "sample.jpg.cradle". Following successful encryption, Cradle creates an HTML file ("_HOW_TO_UNLOCK_FILES_.html") containing a ransom-demand message, and places it on the desktop. Note also that, in dark forums, Cradle is offered as a RaaS (Ransomware as a Service).

Cradle's HTML file contains a message stating that files are encrypted and can only be restored using a unique key. It is currently unknown whether Cradle uses symmetric or asymmetric cryptography. Unfortunately, in either case, decryption without a unique key is impossible. Cyber criminals store this key on a remote server and victims are encouraged to pay a ransom of .25 Bitcoin (currently, 1 Bitcoin is equivalent to ~$1200) to receive it. It is also stated that the ransom must be paid within seven days, otherwise the cost will double. If the payment is not submitted within 14 days, the key is permanently deleted, making it impossible to restore encrypted files. Bear in mind, however, that you should never trust cyber criminals. Research shows that these people often ignore victims, once payments are submitted and it is highly probable that you will be scammed. We strongly advise you to ignore all requests to pay a ransom or contact these people. Unfortunately, there are currently no tools capable of restoring files encrypted by Cradle and you can only restore your files/system from a backup.

There are dozens of ransomware-type viruses virtually identical to Cradle including, for example, Cerber, Salsa, AngryKite, Happydayzz, and BTCWare. These viruses have identical behavior - they encrypt files and make ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Research shows that ransomware is often distributed via spam emails (malicious attachments), third party software download sources (peer-to-peer networks, freeware download websites, free file hosting websites, etc.), fake software updaters, and trojans. Therefore, be cautious when opening files received from suspicious emails, and when downloading software from unofficial sources. Furthermore, keep your installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Be aware, however, that criminals employ fake updaters to proliferate malware - updating installed applications via third party tools is risky.

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 Cradle 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 Cradle 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 Cradle 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 Cradle, 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 Cradle ransomware.

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