How to remove WeRus Ransomware and decrypt .werus files

What is WeRus Ransomware

WeRus Ransomware is a malicious software program that targets user data by encrypting files and demanding a ransom for their decryption. This nefarious ransomware appends a .werus extension to the filenames of the encrypted files, which makes accessing the data without the decryption key impossible. For instance, a file named document.docx would be renamed to document.docx.werus after encryption. The encryption mechanism employed by WeRus is robust, often involving sophisticated cryptographic algorithms that ensure only the attackers can provide the necessary decryption key. Once the encryption process is completed, WeRus changes the desktop wallpaper and drops a ransom note named Readme_[victim’s_ID].txt across the victim’s desktop environment. This note informs the victims of their encrypted files and demands a hefty payment, typically in Bitcoin, within a specific timeframe, warning that failure to comply might result in permanent data loss.

Despite the pressure to pay the ransom, it is crucial to note that there are currently no known decryption tools available for WeRus ransomware, mainly due to its secure encryption methods which can render decryption infeasible without the attackers’ cooperation. Therefore, decrypting .werus files without a backup is generally impossible and attempting to do so without a proper tool could lead to permanent data loss. Unfortunately, even complying with the ransom demand does not guarantee recovery of the encrypted files, as cybercriminals may not provide a functional decryption tool. Consequently, the best approach for users is to focus on preventive measures, such as regularly backing up data on multiple offline and cloud platforms, and maintaining a robust security system to thwart potential infections. In the event of an infection, it is advisable to disconnect the affected device from any network immediately to prevent the ransomware from spreading further.

How WeRus Ransomware infects computers

WeRus Ransomware infiltrates computers primarily through deceptive tactics such as phishing emails and social engineering schemes. Typically, cybercriminals disguise malicious files as seemingly legitimate attachments or links in emails, prompting users to download them. Once opened, these files trigger the ransomware’s payload, initiating the encryption process. Additionally, WeRus can spread through compromised websites that host drive-by downloads, where simply visiting the site can infect a user’s system. It may also exploit software vulnerabilities or use malicious advertisements (malvertising) to distribute its payload. Furthermore, WeRus can be bundled with pirated software or dubious updates, making it critical for users to exercise caution and ensure their systems are fortified with up-to-date security measures.

Dr.Web Rescue Pack

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .werus files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

If you are infected with WeRus Ransomware and removed from your computer, you can try to decrypt your files. Antivirus vendors and individuals create free decryptors for some crypto-lockers. To attempt to decrypt them manually, you can do the following:

How to protect computer from viruses, like WeRus Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

ZoneAlarm Anti-Ransomware Dashboard

ZoneAlarm Anti-Ransomware Alert

ZoneAlarm Anti-Ransomware Blocked

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. WeRus Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
