.cdrpt Files Virus – How Did I Get Infected
The main method which is used by the .cdrpt ransomware to infect the computers of unsuspecting users Is via malicious spammed e-mails that are sent to you as if they come from a company. The e-mails are oriented towards russian-speaking users and they aim to convince that there is an issue and you need to open an attachment to see what exactly is. The issues usally imitated are a problem with our bank account, suspicious activity on your social media profile and even fake order receipts. Here is how such e-mails may appear:
But this is not the only way via which this ransomware virus could enter your computer. The malware may also come as a result of being uploaded on wesbites, pretending to be an installer of a program, a fake license activator, like game patch, crack and other seemingly legitimate programs and also pose as portable program as well.
.cdrpt Files Virus – Further Information
After having clicked on the malicious attachments of this ransomware, it may begin to infect your PC by connecting it to a remote location and using it to download it’s payload files. The virus files are the following:
- An .exe file, likely responsible for the encryption.
- Another .exe file, responsible for creating mutexes, obtaining administrative permissions and triggering scripts.
- Image with the ransom note which is set as a wallpaper.
- Key.res file.
- A ransom note file.
The files are usually in different folders of Windows, whereas the key.res file and the “read me” files are located in the %Documents% directory of your profile directory and the main executables may be in the following Windows system folders:
- %Local%
- %Temp%
- %LocalLow%
- %AppData%
- %Roaiming%
It has not yet been officially confirmed, but the .cdrpt files ransomware may also extract other files which could be with random names and be located in the system folders of Windows. The payload of the ransomware may be downloaded from a third-party domain which is usually from the Tor-network.
The cyber-criminals also drop their ransom note file, which roughly translates to the following ransom note:
“Your files are encrypted using the RSA-2048 algorithm.
If you want to return them, send one of the encrypted files and key.res file to e-mail:
unlckr@protonmail.com
If you do not receive a reply within 24 hours or the letter is returned with an error, then download from the site www.torproject.com browser TOR and with his help go to the site
n3r2kuzhw2h7x6j5.onion – there will be specified a valid mailbox.
Attempts to repair files yourself can irrevocably ruin them!”
The ransom note file may look similar to the previous version of the Unlock92 ransomware:
The ransom note leads victims to a Tor-based page where further instructions can be located. At the moment, the web page displays another e-mail for contact:
→ un92@protonmail.com
On the e-mail it is believed that the victim can negotiate the ransom payoff with the criminals and send them files to decrypt to see that the procedure is working. Nonetheless, paying the ransom is not advisable if you are planning on doing it.
The Unlckr variant .cdrpt may also delete the shadow volume copies of the ifnected omputer by executing Windows Command Prompt as an administrator and within it, triggering the following commands without you even noticing:
→ vssadmin.exe delete shadows /all /Quiet
bcdedit.exe /set {current} bootstatuspolicy ignoreallfailures
bcdedit.exe /set {current} recoveryenabled no
