They are asking for $350,000 in cryptocurrency to delete or buy back sensitive data they allegedly stole from Nuxe labs.
Already suspected of being behind the offensive against the Corbeil-Essonnes hospital, hackers from the Lockbit 3.0 ransomware group claimed on their official blog - hosted on the Darkweb - a cyberattack against the French cosmetics group.
Nuxe admitted on Thursday that it had suffered a computer attack on some of its software, but "the immediate mobilization of the teams made it possible to restore their availability as soon as possible".
Russian-speaking cybercriminals claim to have got their hands on 29 GB of data, or nearly 16,000 computer files.
They release a sample with a grim 13-day countdown to full release if the demanded ransom is not paid.
The documents that we have been able to consult are laboratory analyzes of a cosmetic product developed by Nuxe.
The French brand claims to have filed a complaint and launched an investigation “in order to determine the complete origin of this event, with the assistance of experts specializing in cybersecurity”.
Lockbit hackers have posted their blackmail attempt online.
The most active hacker gang of the moment, Lockbit rents, against a percentage of the money extorted, the 3rd version of its powerful data encryption software.
After breaking into the victim's servers, the hackers will steal the data before encrypting it, ie making it unreadable.
They will then negotiate their return in exchange for a ransom.
But if the victim has backups, they threaten to make this confidential data public.
A phase of negotiations then begins between the bandits and their victims.

Some of the small hands of the group, however, have taken the bad habit of claiming short-lived and baseless attacks like the one against the Ministry of Justice.
