FBI Warns 1.8 Billion Gmail Users of Medusa Ransomware Threat

The FBI has issued a warning to the 1.8 billion Gmail users about a significant ransomware threat posed by the Medusa ransomware group, which has already affected over 300 victims, particularly in critical sectors like healthcare and education. This group employs phishing tactics to exploit software vulnerabilities, allowing them to encrypt files and demand ransom payments that can reach millions. Users are urged to enable two-factor authentication (2FA) to enhance their security and are advised to keep their software updated with the latest security patches. Additionally, maintaining multiple backups of sensitive information is recommended, as well as filtering network access for organizations to prevent unauthorized intrusions. The FBI emphasizes that traditional passwords alone are inadequate for protection against these evolving cyber threats. The Medusa group's tactics include a double extortion model, where they threaten to leak stolen data if the ransom is not paid.
