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 is one of the world's largest and most historic watchmakers, with roughly 12,000 employees and an annual revenue that surpasses $1.6 billion.
On August 10th, 2023, the company published a notice of a data breach informing that an unauthorized third-party gained access to at least a part of its IT infrastructure and accessed or exfiltrated data.

The ransomware group known as BlackCat and ALPHV has now taken credit for the attack and has started leaking files apparently taken from Seiko systems after the victim refused to respond to its extortion attempts. The cybercriminals claim to have stolen 2 Tb worth of files, including employee information, production technology details, video and audio recordings of management meetings, emails, and copies of passports belonging to employees and foreign visitors.

The ransomware group has published screenshots to demonstrate that they have obtained contracts and other corporate documents, confidential technical documents, passport copies, and emails. One screenshot seems to show that they still had access to Seiko email systems on August 14. The hackers are threatening to either sell or leak the information stolen from Seiko if the company refuses to meet their demands.
