Our products detect Medusa ransomware by File Threat Protection as variants of Trojan-Ransom.Win32.MedusaNg. Additionally, products with the Behavior Detection component detect even unknown variants of this malware proactively as PDM:Trojan.Win32.Generic.
With the help of our self-defense technology, our endpoint solution efficiently prevents malicious attempts to interfere with the normal operation of the product.
To keep your company protected against Medusa and other modern ransomware attacks, Kaspersky experts recommend:
- Do not expose remote desktop services (such as RDP) to public networks unless absolutely necessary and always use strong passwords for them.
- Promptly install available patches for commercial VPN solutions providing access for remote employees and acting as gateways in your network.
- Always keep software updated on all the devices you use to prevent ransomware from exploiting vulnerabilities
- Focus your defense strategy on detecting lateral movements and data exfiltration to the Internet. Pay special attention to the outgoing traffic to detect cybercriminals’ connections.
- Back up data regularly. Make sure you can quickly access it in an emergency when needed.
- Use the latest Threat Intelligence information to stay aware of actual tactics, techniques, and procedures (TTPs) used by threat actors.
- Use solutions like Kaspersky Endpoint Detection and Response and Kaspersky Managed Detection and Response service which help to identify and stop the attack in early stages, before attackers reach their final goals.
- To protect the corporate environment, educate your employees. Dedicated training courses can help, such as the ones provided in the Kaspersky Automated Security Awareness Platform.
- Use a reliable endpoint security solution, such as Kaspersky Endpoint Security for Business (KESB) that is powered by exploit prevention, behavior detection and a remediation engine that is able to roll back malicious actions. KESB also has self-defense mechanisms which can prevent its removal by cybercriminals.
