Bear (.bear26) Ransomware

Warning: The Bear ransomware encrypts files and demands payment for a decryption key you may never receive. Acting quickly and safely is critical.

Bear Ransomware – Quick Threat Summary

How Did Bear Ransomware Infect My System?

Bear ransomware is part of the MedusaLocker family, a widespread group of crypto‑extortion malware. The operators typically rely on social engineering and stealth infection chains:

• Email attachments with malicious macros
• Fake installers or cracked software downloads
• Compromised advertisements (malvertising)
• Untrustworthy torrent or file-sharing sites

Once a user executes the malicious file, the ransomware silently installs and begins encryption.

What Bear Ransomware Does to Your Files

After execution, Bear will:

1. Scan the system for files — documents, photos, databases, media, etc.
2. Encrypt each with strong cryptography (RSA & AES)
3. Rename encrypted files by appending .bear26 (or similar)
4. Replace your desktop wallpaper
5. Drop a ransom note (READ_NOTE.html) demanding payment for decryption
6. Modify system settings to persist until removed

This process immediately locks out access to your data. Attempting to rename or tamper with encrypted files can make recovery impossible.

Should You Pay the Ransom?

No. Paying cybercriminals rarely results in decryption, and it incentivizes further criminal acts. Even if communication appears possible via the emails listed in the ransom note, there’s no guarantee of receiving a working decryption key — and your data could be permanently lost.

Instead:

• Restore files from known clean backups (offline or cloud)
• Use professional data recovery services if necessary
• Report the incident to law enforcement
• Improve network defenses to avoid repeat infections

Bear Ransomware Ransom Note — What It Says

The ransom note dropped by Bear claims:

Your network has been compromised and all files encrypted with RSA/AES.
Attempts to use third-party tools to restore files will corrupt them.
Contact us to negotiate a decryption key, but the ransom increases if you delay.

Bear threatens to publish stolen data if ransom isn’t paid.

How to Remove Bear Ransomware from Windows

1. Isolate the infected system – Disconnect from the internet and network immediately
2. Boot into Safe Mode – Prevent the ransomware from running on startup
3. Scan with reputable security software – Use updated antivirus/anti-malware tools to detect and remove Bear
4. Quarantine and clean infected files – Follow the security software’s guidance for safe removal
5. Don’t reinstall the ransomware – After removal, ensure no remnants remain that could re-encrypt files

While removal stops further encryption, it does not restore your encrypted files — that requires backups or professional recovery tools.

Prevention and Future Protection

• Backup regularly to offline or cloud storage
• Keep systems updated
• Use strong, unique passwords and MFA
• Educate users on phishing and safe downloads
• Deploy endpoint protection and network monitoring

Investing in layered security greatly reduces the risk of future ransomware incidents.

Conclusion

Bear ransomware is a dangerous file-encrypting malware that can cripple access to important data. It spreads through common vectors like email attachments and malicious downloads, encrypting files and demanding payment for a decryption key you likely won’t receive.

Focus on removal, recovery from backups, and security improvements rather than paying attackers.

Manual Ransomware Removal Process

Important: Manual removal is recommended only for experienced users, as incorrect actions can lead to data loss or incomplete removal of the ransomware. If unsure, consider the SpyHunter Removal Method for a guided, automated solution.

Step 1: Disconnect from the Internet

1. Immediately disable Wi-Fi or unplug the Ethernet cable to prevent the ransomware from communicating with remote servers.
