V (Dharma) Ransomware Silently Does A Lot Of Damage

Understanding V (Dharma) Ransomware

V (Dharma) Ransomware is a file-locking program belonging to the Dharma family, a notorious group of threats that have been encrypting data for years. Once it infiltrates a system, it modifies files by appending a unique victim ID, an email address, and the ".V" extension. The ransomware also leaves behind a ransom note in the form of a pop-up message and a text file named "info.txt."

Victims are informed that their files are inaccessible and instructed to email the attackers to negotiate a decryption process. The ransom note warns against renaming files or attempting to use third-party decryption tools, claiming these actions could cause permanent data loss. The attackers even offer to decrypt up to three small files for free as proof of their ability to restore data.

The Goal Behind the Encryption

Like other ransomware, V (Dharma) is designed to extort money from its victims. The attackers demand payment, usually in Bitcoin, in exchange for a decryption tool. If no response is received within 12 hours, the ransom note directs victims to a secondary email address for further contact. The inclusion of multiple contact methods suggests that the attackers want to ensure communication remains open, increasing the likelihood of payment.

Despite these promises, paying the ransom is never a guaranteed solution. In many cases, victims who comply with the demands never receive decryption keys, leaving them without both their data and their money.

Here's what the ransom note says:

All your files have been encrypted!
Don't worry, you can return all your files!
If you want to restore them, write to the mail: vijurytos@tuta.io YOUR ID -
If you have not answered by mail within 12 hours, write to us by another mail:vijurytos@cyberfear.com
Free decryption as guarantee
Before paying you can send us up to 3 files for free decryption. The total size of files must be less than 3Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)

Attention!
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam

How V (Dharma) Ransomware Operates

Once inside a system, V (Dharma) searches for and encrypts files stored on local and network drives. It also takes steps to prevent easy recovery, such as disabling firewalls and deleting shadow copies of files, which are often used for restoration. The ransomware embeds itself in the system by copying its code to the "%LOCALAPPDATA%" folder and modifying the Run registry keys, ensuring that it remains active even after a reboot.

Interestingly, some ransomware variants avoid encrypting data in specific locations. This behavior suggests that attackers may be targeting particular regions or organizations while avoiding others.

Ransomware and Its Larger Implications

Ransomware programs, including V (Dharma), are among the most disruptive digital threats. By locking critical data, they can paralyze businesses, organizations, and individual users alike. Since attackers demand cryptocurrency as payment, tracking and recovering funds is extremely difficult.

While paying to retrieve encrypted files may seem like the only option, doing so fuels the ransomware economy, encouraging cybercriminals to continue their attacks. Law enforcement and cybersecurity professionals advise against making payments, as there is no guarantee that attackers will follow through on their promises.

How V (Dharma) Ransomware Spreads

Dharma ransomware is often distributed through weak Remote Desktop Protocol (RDP) connections. Attackers use brute force or dictionary attacks to guess login credentials, gaining access to systems with poor security measures. Once inside, they manually execute the ransomware, locking files within minutes.

Threat actors also spread ransomware through phishing emails, malicious attachments, and compromised websites. Fraudulent advertisements, pirated software, and software vulnerabilities provide additional opportunities for attackers to infiltrate systems. Even seemingly legitimate download sites can unknowingly host ransomware-laden files, making it essential for users to verify the authenticity of any download.

Preventing Ransomware Infections

Given the destructive nature of ransomware, prevention is the best strategy. Users should be cautious when handling emails, especially those from unknown senders. Suspicious attachments and links should be avoided, as they could trigger an infection upon opening.

Software should always be downloaded from reputable sources, such as official vendor websites and trusted app stores. Avoiding pirated programs and third-party installers minimizes the risk of unintentionally downloading harmful files. Additionally, businesses should secure RDP access by using strong passwords and implementing multi-factor authentication to reduce unauthorized access.

The Importance of Backups

Backing up important data is one of the most effective defenses against ransomware. Regular backups stored on external or cloud-based systems ensure that files can be restored without needing to comply with ransom demands. It is crucial to keep backups disconnected from primary devices to prevent ransomware from encrypting them as well.

Final Thoughts

V (Dharma) Ransomware exemplifies how file-encrypting threats continue to evolve, making data protection more critical than ever. Since attackers use various methods to distribute ransomware, awareness, and proactive security measures play a key role in preventing infections. By staying vigilant, avoiding suspicious downloads, and keeping secure backups, users and organizations can significantly reduce the impact of ransomware attacks.
