Crytp0lock Ransomware – Distribution Means

The most common way of Crytp0lock ransomware distribution is spam email campaigns that contain its malicious sample. The emails allow hackers to impersonate legitimate sources known to users and quickly convince them to interact with the presented content. The malicious ransomware payloads can be distributed in email attachments that once opened on the PC trigger the attack or compromised URLs that download the ransomware unnoticeably when clicked.

These malicious ransomware files may also be distributed via popular social networks like Twitter, Facebook, Reddit, WhatsApp, etc.

Crytp0lock Ransomware – Detailed Overview

Crytp0lock ransomware name is based on the malicious executable file that triggers the infection – KeyMaker.exe. The file is used to start and control the attack. And once it is running on the system it initiates a sequence of system settings modifications to ensure its stable presence on the infected host. For the purpose Crytp0lock ransomware changes and creates values in Windows Registry keys. The most frequent changes caused by ransomware infections like Crytp0lock affect the Run and RunOnce registry keys. Both keys manage currently running processes as well as all processes that are set to run automatically each time the Windows operating system starts. Thus by using them, the ransomware can set its self-starting on each bootup. Another application of malicious registry modifications concerns the automatic display of its ransom message READ_IT.txt at the end of the attack.

Being based on the open-source code of HiddenTear ransomware, Crytp0lock or KeyMaker crypto virus is considered to run a specific command line in the Command Prompt panel:

→vssadmin.exe delete shadows /all /Quiet

The ransomware utilizes this command to erase all Shadow Volume Copies created in the Windows OS, thus eliminating one of the ways to recover .CryptedOpps files.

In order to complete all malicious activities and infect the system efficiently, Crytp0lock ransomware may create additional malware files or connect a server controlled by hackers to drop all necessary files. Some but not all malicious files may be situated in the following folders:

  • %Temp%
  • %Roaming%
  • %UserProfile%
  • %Temp%
  • %AppData%

Crytp0lock Ransomware – Data Encryption Process

The threat is designed to encipher text documents, photos, music, videos, databases, archives, presentations, projects, and spreadsheets. Or all file types that are frequently used to store valuable information. The encryption process is done with the strong AES cipher that modifies the original file code of all target data and generates a unique decryption key. The key is then sent to hackers who extort ransom payment of $200 in Bitcoins for it.

Once all target files are encrypted they receive the malicious extension .CryptedOpps and remain unusable until the decryption key is applied to the decrypter. At the end of the attack Crytp0lock, crypto virus drops a file called READ_IT.txt and displays it on the PC screen. The file contains a ransom message that reads the following:

Opps all your files have been encrypted with crytp0lock
You can unlock your files by paying 200 dollars in Bitcoin
Send payment too bitcoin address 17Dndl5gV6mMn4Rm3FNHXtwYeXk9ZUikbE you can also contact us at Wecanhelp@protonmail.com for other payments or questions.
You have 2 days to PAY before timer starts deletion of files.

It is highly advisable to avoid any contact and negotiations with cyber criminals and better not trust their promises. Beware that paying the ransom doesn’t guarantee that .CryptedOpps files will be decrypted. First, the ransomware code can be broken thus not generating working decryption keys. Second, cyber criminals can ignore you and don’t send the key even after a ransom payment.

Remove Crytp0lock Ransomware from Your PC and Restore .CryptedOpps Files

If your computer got infected with the Crytp0lock ransomware virus and you choose to take the manual removal approach, you should have a bit of experience in removing malware. Beware that you should get rid of this ransomware as quickly as possible otherwise you cannot safely use your PC.

After the removal, look at step “Restore files encrypted by Crytp0lock” to find out how you can restore .CryptedOpps files, but don’t forget to back up all encrypted files before taking any actions.
