First observed in 2019, the Medusa ransomware (also known as MedusaLocker) operates as a ransomware-as-a-service (RaaS) business model. It mainly targets the healthcare and educational sectors, as well as enterprises that process high volumes of personal identifiable information (PII).

Medusa is a type of ransomware that encrypts files on a victim’s computer or network, rendering them inaccessible until a ransom is paid to the attackers.

The name “Medusa” comes from the mythological creature with snakes for hair, which could turn people into stone with a single look. Similarly, this ransomware “freezes” files, making them unopenable.

Ransomware attacks typically follow a pattern:

  • Infection
  • Encryption
  • Ransom Note
  • Payment

To protect against Medusa and other ransomware attacks, it’s crucial to follow these cybersecurity best practices:

  1. Regular Backups
  2. Security Software
  3. Email Safety
  4. Software Updates
  5. Network Security
  6. User Education

Remember, the best defense against ransomware is prevention and preparedness. Regularly update your knowledge about cybersecurity threats and best practices to stay one step ahead of cybercriminals.
