Remove Cryptobot and Restore the Encrypted Files

Computer SecurityCryptobot is a piece of ransomware that has the same functionality as many other file encrypting threats. Once activated, Cryptobot encrypts valuable information on the affected machine and demands payment in order to decrypt it. Cryptobot has a Trojan component that can allow backdoor access to the compromised PC and be employed by cyber criminals for a variety of malicious activities.

Cryptobot Ransomware – Distribution and Behavior

The Trojan is delivered via spam email message that contains a malicious attachment. Once it is downloaded, the malicious script is launched, and the threat is activated. Cryptobot starts encrypting files with the following extensions:

→.jpg, .pdf, .jpeg, .cdr, .doc, .docx, .zip, .xls

Then the victim is presented with a ransom note in Russian language containing information about the already finished file-encrypting process, payment details and decryption options.

In order to launch the threat with every system startup, Cryptobot creates a registry key in the following location:

→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

This means that any newly created documents might get encrypted as well the next time the victim starts the computer.

The malicious files created by the ransomware are located in:

→C:\Users\AppData\Local\Temp\ directory

Experts recommend against paying the required sum because there is no guarantee that the users will have their files restored. Competent anti-malware tools are capable of eliminating the threat, but the encrypted files can only be restored from a recent backup.

We recommend trying to restore the damaged files from the Shadow Volume Copies in case they were not affected by Cryptobot.

To do so, follow the instructions below.

Remove Cryptobot and Restore the Encrypted Files

Stage One: Remove Cryptobot

1. First and most important – download and install a legitimate and trustworthy anti-malware scanner, which will help you run a full system scan and eliminate all threats. donload_now_250

2. Run a second scan to make sure that there are no malicious software programs running on your PC. For that purpose, it’s recommended to download ESET Online Scanner.

Your PC should be clean now.

Stage Two: Restore the Encrypted Files

Option 1: Best case scenario – You have backed up your data on a regular basis, and now you can use the most recent backup to restore your files.

Option 2: Try to decrypt your files with the help of Kaspersky’s RectorDecryptor.exe and RakhniDecryptor.exe. They might help you in the process but keep in mind that they were not specially designed to encrypt information that was decrypted by this particular ransomware.

Option 3: Shadow Volume Copies

1. Install the Shadow Explorer, which is available with Windows Vista, Windows 7, Windows 8 and Windows XP Service Pack 2.

2. From Shadow Explorer’s drop down menu choose a drive and the latest date you would like to restore information from.

3. Right-click on a random encrypted file or folder then select “Export”. Select a location to restore the content of the selected file or folder.
