Threat Database Ransomware Watz Ransomware

Watz Ransomware

Ransomware is harmful software that encrypts data until a ransom is paid. This cyber threat is increasingly prevalent, targeting individuals and organizations to extort money by compromising their critical data.

During a detailed analysis of malware threats, cybersecurity researchers uncovered a new variant known as the Watz Ransomware. This particular strain encrypts files and appends the extension '.watz' to the filenames. For example, it renames '1.png' to '1.png.watz' and '2.pdf' to '2.pdf.watz.' Additionally, the Watz Ransomware leaves behind a ransom note named '_readme.txt' to instruct victims on how to pay the ransom.

Researchers have identified Watz as part of the notorious STOP/Djvu Ransomware family. This connection indicates a significant risk that cybercriminals might also deploy other unsafe software, such as RedLine or Vidar, on the compromised devices to steal sensitive information.

The Watz Ransomware Extorts Victims by Locking Their Data

The ransom note from the Watz Ransomware claims that all files, including pictures, databases, and documents, have been enciphered using a strong encryption algorithm. It asserts that the only way to recover the encrypted files is to purchase a decryption tool and an exclusive key from the attackers.

The note offers to decrypt one file for free as proof of their ability to restore the data and provides contact information: and It states that the private key and decryption software are priced at $999, but offers a 50% discount if the victim contacts the cybercriminals within 72 hours.

The STOP/Djvu Threats Have Remained a Prevalent Danger on the Cyber Scene

The STOP/Djvu Ransomware threats execute their attacks through multiple stages, starting with the deployment of several shellcodes and culminating in the encryption of files. To evade detection by security systems, the ransomware employs techniques to extend its running time, thereby reducing the likelihood of being detected.

Initially, these threats use dynamic API resolution to access necessary tools without arousing suspicion. Following this, the malware employs a tactic known as process hollowing, where it creates a duplicate of itself disguised as a different process, effectively concealing its malicious activities.

Most ransomware variants operate in a similar fashion. They encrypt data and leave ransom notes demanding payment, typically in cryptocurrency. These ransom notes often warn victims that their files will be permanently lost if the ransom is not paid. Unfortunately, decrypting the files without the attackers' assistance is rarely possible.

How to Ensure the Safety of Your Devices and Data?

To ensure the safety of your devices and data, follow these essential practices:

  • Regularly Update Software: Keep your operating system, applications, and security program up to date to protect against the latest threats and vulnerabilities. Enable automatic updates when available to ensure you don't miss important patches.
  • Use Strong, Unique Passwords: Create strong passwords for all your accounts and devices, and use a different password for each one. Consider using a dedicated password manager to help generate and store complex passwords securely.
  • Enable Two-Factor Authentication (2FA): Enhance the security of your accounts by enabling 2FA, which requires a second form of verification, such as a text message code or authentication app, in addition to your password.
  • Backup Your Data: Regularly back up your essential data and files to an external hard drive or a cloud-based service. Ensure backups are performed automatically and periodically test your backups to verify they can be restored.
  • Be Wary of Phishing Tactics: Be cautious of unsolicited emails, messages, or websites asking for personal information. Verify the authenticity of any source before clicking on links or downloading attachments.
  • Use Anti-Malware Software: Install reputable anti-malware products on your devices to detect and block unsafe activities. Schedule regular scans to identify and remove threats.
  • Secure Your Network: Safeguard your home or office network by using a strong and unique passwords for your Wi-Fi. Consider enabling network encryption (WPA3) and concealing your network's SSID to make it less visible to outsiders.
  • Limit Access and Permissions: Only grant necessary permissions to applications and services. Adjust and review the privacy settings on all of your devices and accounts to limit the amount of shared personal information.
  • Educate Yourself and Others: Stay informed about the latest cybersecurity threats and best practices. Share this knowledge with family members and colleagues to help them protect their devices and data as well.
  • Monitor for Suspicious Activity: Regularly review your account statements, credit reports, and device activity logs for any signs of unauthorized access or unusual behavior. Report any suspicious activity immediately.

By following these steps, users are likely to significantly minimize the risk of cyberattacks and ensure the safety of their data and devices.
