The cyberiminals continue to create new variants based on the STOP/Djvu family. It is essential to note that threats from this family are frequently accompanied by additional malicious payloads. For instance, attackers may deploy infostealers such as Vidar or RedLine on compromised devices.
The Qarj Ransomware works by running an encryption algorithm that uses an unbreakable cryptographic algorithm to lock files stored on the targeted device, rendering them inaccessible to the user. The ransomware modifies the file names by adding a new extension, '.rigd,' to the original name of each encrypted file. In addition, the Qarj Ransomware drops a ransom note in the form of a text file named '_readme.txt.' The note demands that victims make a ransom payment in exchange for the potential decryption of the affected files.

Cybercriminals Take the Victim’s Data Hostage via the Qarj Ransomware
The ransom note of the Qarj Ransomware bears a striking resemblance to the instructions given by other variants from the STOP/Djvu family. The note informs victims that they must pay $980 in ransom to receive the decryption key and tool from the attackers. However, there is an opportunity to reduce this amount by half. To do so, victims must contact the attackers via the email addresses provided within 72 hours of the Qarj Ransomware infection.
The email addresses listed in the note are 'firstname.lastname@example.org' and 'email@example.com.' To prove their ability to restore the victims' data, the attackers offer to unlock a single encrypted file for free, which victims can attach to their message. However, the file should not contain any valuable information.
It is crucial to note that the Qarj Ransomware is not the only variant of the STOP/Djvu family to demand ransom in exchange for the decryption key and tool. Victims should exercise caution and avoid paying the ransom if possible, as there is no guarantee that the attackers will fulfill their end of the bargain. Moreover, paying the ransom may encourage cybercriminals to continue with their illegal activities, and the victims' personal and sensitive data may still be at risk even after paying the ransom.
Make Sure that Your Devices and Data Are Sufficiently Protected
Ransomware is malware that can encrypt a user's files, turning them inaccessible unless a ransom is paid to the attacker. Here are some ways users can protect their devices and data from ransomware attacks:

- Use strong passwords: Use strong, unique passwords for all online accounts and avoid using the same password across multiple accounts.
- Avoid suspicious links and attachments: Do not accesssuspicious links download attachments from unknown sources, as they may contain malware.
- Enable two-factor authentication: Use two-factor authentication whenever possible, as it provides an additional layer of security to the login process.
- Backup important data: Regularly backup important files and store them on a separate device or in the cloud. This makes it certain that data can be recoved in the event of a ransomware attack.
- Install reputable security software: Install reputable anti-malware software and keep it up to date.
- Be wary of social engineering tactics: Attackers may utiliuze social engineering tactics to trick users into clicking on links or downloading attachments. Be suspicious of unexpected messages or requests, even if they appearseem to come from a trusted source.
By implementing these precautions, users can help protect their devices and data from ransomware attacks. If an attack does occur, it is important not to pay the ransom, as there is no guarantee that the cybercriminals will provide the decryption key or tool.
