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:
- Regular Backups
- Security Software
- Email Safety
- Software Updates
- Network Security
- 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.
