At a time when cybersecurity is making headlines almost daily, here's a story that's truly out of the ordinary: After France which did the same thingTHE FBI has just finalized a particularly daring operation, namely legally hacking more than 4,200 computers… to protect them!

At the heart of this matter is PlugXA malware particularly sneaky initially developed in 2008 by front companies linked to the Chinese Ministry of State Security. This little digital monster has a chilling peculiarity: it spreads via USB ports, a bit like those viruses that passed from floppy disk to floppy disk in the 90s. Except that here, we're talking about a data protection tool. ultra-sophisticated espionage capable of taking total control of your machine.

The group behind this malware, called Mustang Pandaworks directly for the Chinese government. Their specialty is infiltrating the systems of government organizations, private companies and activist groups around the world. Thus, since 2014, they have notably targeted European shipping companies, several European governments, Chinese dissident groups and numerous Asia-Pacific countries.

Faced with this threat, the FBI mounted an international operation in collaboration with American justiceFrench justice and French cybersecurity experts from Sekoia.io. The French company played a crucial role in identifying between 90,000 and 100,000 unique infected IP addresses in more than 170 countries.

The operation took place in several phases:

  1. Phase 1 : Identification of infected machines via their communication with the cybercriminals' control server
  2. Phase 2 : American side, obtaining 9 successive judicial mandates in August 2024
  3. Phase 3 : Development of a malware self-removal command
  4. Phase 4 : Remote cleaning of infected systems without disrupting their normal operation

This operation marks a turning point in the fight against state cybercrime since the FBI and the American Department of Justice have demonstrated that it is possible to intervene directly on infected machines, while respecting a strict legal framework and ensuring the transparency of their actions.

And the owners of the cleaned computers were informed via their Internet service providers. This proactive approach perhaps represents the future of cyber defense, where authorities no longer simply observe and alert, but actively intervene to protect citizens.

Well, even if the FBI cleans up, it's better to be safe than sorry. Here are some essential tips to avoid this kind of thing:

  • Beware of USB drives : Do not plug any USB media into your computer.
  • Keep your system up to date : Security updates are crucial.
  • Use a powerful antivirus :And keep it updated!
  • Enable your firewall : Essential protection against intrusions.
