GandCrab decryption keys and protection guide against ransomware

What happens when malware retires? The whole world learns your secrets. Good news for today: decryption keys for multiple versions of GandCrab are out. Keys were released soon after the announcement from GandCrab developers that they were shutting everything down and retiring after earning, more than $150 million in 18 months GandCrab.

Releasing of the kyes made all strains of GandCrab less dangerous but cybersecurity researchers are warning that new strains, with new encryption keys, will surely be developed in the future.

Remember everything can be hacked. In order to stay away from any threats related to the cyber world, we recommend the install of antivirus for Windows or antivirus for Mac on every device that you own, depending on which OS your device is running. If you are a company, it is also recommended to hire every year a specialized cybersecurity company that will run annual tests on your company’s network. These tests include penetration testing and ethical hacking tests;

Here are the Master Decryption Keys:

Protection guide against GandCrab and all :
1. Train personnel to identify phishing attempts and how to respond to them.
2. Implement a strong patch management system and enable automatic patching.
3. Implement auto-updates for antivirus software.
4. Implement the principle of least privilege and strictly manage privileged accounts.
5. Implement a robust backup system and store backups offline.
6. Implement strong authentication requirements for the remote desktop protocol (RDP).

We would continue to monitor the cybersecurity world. Meanwhile, users should keep a keen eye out for any cyber-attacks.
