Cyber criminals always find new ways to scandal you, it is duplicating a government agency, creating a fake website or providing disguised malware as software updates. When you think that you have seen it all, they bring a new strategy.
Now, the FBI has issued a warning: hackers are using a “time-travel” technique to bypass your device’s protection systems. No, we’re not talking about the actual time travel (though it won’t be anything?). This is a sophisticated cybertack where hackers manipulate the internal clock of a system to snatch past protection defense.

The concept of “Time-Traveling Hackers” refers to a sophisticated cybettack technique not literally, but the hackers manipulate the internal clock of a system to bypass the security measures. The attack is reported to be bound to the Medusa Ranswireware gang.
In this type of attack, hackers change the system date on a target device and use security certificates when those credentials were still valid. For example, a protection certificate that expires, can be used again in the term of 2020 if the system’s watch comes back to 2019 This is the contaminated software signed with these old credentials can be recognized as valid by the system, effectively traveling back to “back” from the security perspective.
This technique was significantly used in the Medusa Ranswear attacks, which aimed at critical infrastructure and made a request FBI Cybercquirety Advisory (AA 25-071) in 2025 before. The promotion has influenced more than 300 critical infrastructure targets. The invaders combine this method with social engineers and use comparative weaknesses to make the threat wide.
The FBI warns that these national attacks create a significant risk, as they can disable modern protection protection like Windows Defender to drive the system to take old drivers or software.

What does the FBI recommend?
Dition like rigid robots and specialized cameras, such as detection and rescue equipment, often fight the disaster region. The cameras only follow the straight paths, forcing teams to simply see more ruins to see more ruigo rigot robots tight, weak in unstable places and expensive to repair after being damaged. And the risk of slow, exhausting and responsive protection of manual investigation.

5 ways to stay safe from Medusa Malware
1) Use strong antivirus software: A strong antivirus is not merely to catch old school viruses anymore. It can detect phishing links, block contaminated downloads and turn off the ransware before the foot. Since the Medusa Gang uses fake updates and social engineering to make users strategy, having strong antivirus software adds a critical level of protection against threats that you do not see. Pick me the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devicesThe
2) Enable Bi-Factor Authentication (2 FA): FBI specifically recommends To enable 2FA across all servicesEspecially for high-value goals such as webmail accounts, VPN and remote access tools. 2 FA Attacks make the attackers significantly stronger, even if they are able to steal your username and password through phishing or other techniques.
3) Use strong, unique passwords: Many Ranswear groups, including Medusa, depend on re -used or weak passwords to achieve access. Using a strong password (long, random and feel unique in each account) reduces that risk. A password manager can help you create and store complex passwords so you don’t have to remember them yourself.

4) Monitor to change the time of suspicious system: The key to this “time-transporting” attack is the clock manipulation: hackers come back to a device’s watch at a time when expired security certificates were still valid. It allows the old and potentially contaminated software to appear credible. Be careful about changing the unexpected system time and if you are operating an agency use the tools that use the flag and log this type of configuration shift.
5) Keep updated systems and patch the familiar weaknesses: There is a track record of absorbing unpaid systems in promoting the Medusa Ransomware. This means old software, old drivers and ignoring security updates can turn out to all entrance points. Regular Installing updates for your OS, app and drivers One of the most effective ways to be protected. Do not turn off these system notifications; They exist for a reason.

Curtain
Medusa attacks a good example of how cyber criminals are changing. Instead of relying on the traditional tidal approach such as brut forces or obvious exploitation, they continue to notice the basic logic that depends on the effectiveness of the systems. In this case, it is something as simple as the system clock. This national strategy challenges the way we think about protection. It’s not only about creating a strong defense, but also about the technology we use every day to question the default estimates created.
