In spring 2019, the C3N Digital Crime Center in France received a warning saying that an e-mail virus had been used by cybercriminals to control computers without attracting the attention of the owners.
"We managed to track down where the command server was, the control tower for the "botnet" network of infected computers," C3N chief Jean-Dominique Nollet told France Inter radio.
The French Digital Crime Enforcement Police have uncovered a hacker network responsible for infecting 850,000 computers in more than 100 countries. The criminals themselves are still at large now, but their lead server was found and neutralized with assistance of the US FBI.
Computer infection was carried out by installing Retadup malware. Mostly, hackers attacked users who lived in Central and South America. The virus spread through mail or infected storage media (flash and hard drives for computers). Infected computers in stealth mode mined for hackers Monero cryptocurrency or sent personal data.
Hackers began their criminal activity back in 2016. C3N employees learned about the existence of the main server only in 2019. Over the past time, hackers not only infected more than 800,000 computers, which is enough to bring down a significant segment of the Network but also earned several million euros by conducting illegal operations.
