FBI Warns of Time-Traveling Hackers

The Federal Bureau of Investigation (FBI) has issued a warning about a sophisticated cyberattack technique used by hackers to bypass security measures. The attackers, reportedly affiliated with the Medusa ransomware gang, are using a "time-traveling" method to manipulate a system's internal clock and exploit expired security certificates.

This attack is not literal time travel, but rather a clever way for hackers to gain unauthorized access to devices and steal sensitive information. By altering the system date on a targeted device to a time when security certificates were still valid, malicious software signed with these outdated certificates can be recognized as legitimate by the system.

Imagine a situation where an attacker sets your device's clock back in time to 2019, allowing them to use outdated drivers or software that was once considered trustworthy. This technique has been used in recent Medusa ransomware attacks, which have targeted critical infrastructure and affected over 300 critical targets.

The FBI is urging organizations to take immediate action to protect themselves from this type of attack. To stay safe, they recommend turning on two-factor authentication (2FA) everywhere, especially for important services like webmail and VPNs. Additionally, it's essential to have strong endpoint protection, clear security policies, and to monitor system settings for any unusual changes.

5 Ways to Stay Safe from Medusa Malware

Here are five ways to protect yourself from the Medusa malware:

  • Use strong antivirus software: A robust antivirus program can detect phishing links, block malicious downloads, and stop ransomware before it takes hold.
  • Enable two-factor authentication (2FA): The FBI specifically recommends enabling 2FA across all services, especially for high-value targets like webmail accounts, VPNs, and remote access tools.
  • Use strong, unique passwords: Many ransomware groups rely on reused or weak passwords. Make sure to use a password manager and choose complex, unique passwords for each account.
  • Keep systems updated and patch known vulnerabilities: Regularly install updates for your OS, applications, and drivers to stay protected from exploits.
  • Monitor system settings and flag unusual configuration shifts: Use tools that can log and flag configuration changes, such as those made by the attackers using this "time-traveling" technique.

The Medusa Attack: A Shift in Cyber Tactics

The Medusa attack is an example of how cybercriminals are evolving their tactics to bypass traditional security measures. By targeting the basic logic that systems depend on to function, hackers like the ones using this "time-traveling" method can gain unauthorized access to devices and steal sensitive information.

Supporting Individual Users in Protecting Their Data and Devices

Technology companies can better support individual users by providing clear instructions and tools for staying safe online. This could include easy-to-use antivirus software, simple setup guides for 2FA, and regular updates with security patches.
