Japanese watchmaker Seiko breached by BlackCat ransomware gang

The BlackCat/ALPHV ransomware gang has added Seiko to its extortion site, claiming responsibility for a cyberattack disclosed by the Japanese firm earlier this month.

Seiko apologized to the potentially impacted customers and business partners and urged them to be vigilant against email or other communication attempts potentially impersonating Seiko.

Today, the BlackCat ransomware group claimed to be behind the attack on Seiko, posting samples of data that they claim to have stolen during the attack.

Most worryingly, the threat actors have leaked samples of what they claim are confidential technical schematics and Seiko watch designs.

BleepingComputer has contacted Seiko for additional comments on the threat actor’s claims, but we have not received a response by publication time.
