INCIDENT: REvil Ransomware Shut Down Multiple Plants at Asteelflash

Asteelflash, a leading French electronics manufacturing services company, has suffered a cyberattack by the REvil ransomware gang who is demanding a $24 million ransom. While Asteelflash has not publicly disclosed an attack, BleepingComputer found this week a sample of the REvil ransomware that allowed access to the Tor negotiation page for their cyberattack. LeMagIT, a French cybersecurity news portal, reported an Asteelflash representative stated that "the incident is being evaluated." Neither BleepingComputer nor LeMagIT could confirm whether the attack was successful in encrypting files on affected systems.

The company's press release states: "Asteelflash has detected a cyber security incident during a routine check by its IT teams. We immediately took action to contain the REvil-type ransomware and limit its spread. We have not been in touch with the Hackers" There are no details about the company's intentions regarding the ransom.
