/ 1 min read
🗝️ Medusa ransomware emerges as a significant threat in 2023. Medusa is a ransomware-as-a-service (RaaS) platform that primarily targets organizations running Windows, exploiting unpatched systems and utilizing initial access brokers (IABs) to gain unauthorized access. The ransomware encrypts sensitive files, appending the .MEDUSA extension, and threatens to publish stolen data if ransoms are not paid. Notable victims include Minneapolis Public Schools and various cancer centers, with the majority of attacks occurring in the U.S. and the U.K. To protect against Medusa, organizations are advised to implement secure backups, maintain updated security solutions, use strong passwords, and educate staff on cyber threats. Medusa also operates a dark web leak site and a public Telegram channel to publicize its attacks.
