In this article, you will find more information about Wrar virus as well as a step-by-step guide on how to remove malicious files from the infected system and how to potentially recover encrypted .wrar files.
.wrar Virus File
When you see the extension .wrar appended to the names of all your valuable files then your computer is infected with a strain of Dharma ransomware. Apparently the threat Wrar virus is named after the malicious extension it uses. Like a typical data locker ransomware, Wrar virus sneaks into computer systems with the goal to encode personal files and extort a ransom fee for their recovery.
During the attack, it implements a large number of malicious changes that seriously disrupt the security of the infected system. For the Wrar Dharma ransomware attack to begin, the executable file xxx.exe should be started on the system. Afterward, the threat becomes able to scan the system for target files and encodes them with strong cipher algorithms like AES and RSA. Finally, the ransomware drops a ransom message to extort a ransom payment.

Dharma Ransomware (.wrar File) – Distribution and Impact
A strain of Dharma ransomware that uses the suffix .wrar for files it encrypts has been detected in the wild. The infection files that trigger an attack with the so-called .wrar virus file are likely to be lurking across the web disguised as fake software installers, spam emails with malicious components, phishing websites, malicious advertisements, scam pop-ups, etc.
Malspam is likely to be the most preferred one as it enables hackers to spread the threat on a large scale. This spread technique is realized via email spam messages that attempt to deliver malicious code on targeted PCs. The emails that are part of these campaigns usually attempt to trick you to load a corrupted web page in the web browser or open a file attachment with embedded malicious code on your PC system. The senders of these emails are often stated to be representatives of well-known services and institutions. The email addresses are often spoofed as well.
The moment .wrar virus’s activation file is started on the computer system, it triggers a long sequence of malicious operations that first enable the threat to evade detection and then help it to corrupt the whole system. The ransomware misuses system functionalities by executing malicious files. For example, it creates files that access the Registry Editor on the background of all other processes and adds malicious values there. As a result, the ransomware becomes able to load automatically malicious files every time you start the operating system. So don’t forget to clean your registries when removing the threat from your infected PC.
As a strain of Dharma ransomware family, .PBD virus encrypts target files by utilizing the strong cipher algorithm AES. The encryption process is realized with the help of a built-in cipher module. Once activated this module scans all drives for target types of personal files so it can apply changes to their code.
The primary goal of Wrar virus is to scan system drivers for common files that are likely to store valuable personal information and encrypt these files without being detected. For the encryption process, this Dharma ransomware strain uses strong cipher algorithms like AES and RSA. That’s why it leaves encrypted files completely inaccessible. In addition, it marks the files with several extensions. One of these extensions is the hackers’ associated email supp37@cock.li and another is the .wrar
So here is how a file encrypted by Dharma Wrar ransomware appears:
Following data corruption, the Wrar ransomware will demand a ransom fee for a recovery tool. Unfortunately, you may not be able to view the information stored by the following files of yours:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Below you can see the content of the ransom message that appears when the infection process ends:
All FILES ENCRYPTED “RSA1024”
All YOUR FILES HAVE BEEN ENCRYPTED!!! IF YOU WANT TO RESTORE THEM, WRITE US TO THE E-MAIL supp37@cock.li
IN THE LETTER WRITE YOUR ID, YOUR ID 1E857D00
IF YOU ARE NOT ANSWERED, WRITE TO EMAIL:supp37@cock.li
YOUR SECRET KEY WILL BE STORED ON A SERVER 7 DAYS, AFTER 7 DAYS IT MAY BE OVERWRITTEN BY OTHER KEYS, DON’T PULL TIME, WAITING YOUR EMAIL
