BlackCat ransomware group claims the hack of Seiko network

Pierluigi Paganini August 21, 2023

The BlackCat/ALPHV ransomware group claims to have hacked the Japanese maker of watches Seiko and added the company to its data leak site.

On August 10, 2023, the Japanese maker of watches Seiko disclosed a data breach following a cyber attack.

“Seiko Group Corporation (hereinafter referred to as “the Company” or “we”) has confirmed that on July 28th of this year, the Company suffered a possible data breach. It appears that some as-yet-unidentified party or parties gained unauthorized access to at least one of our servers. Subsequently, on August 2nd, we commissioned a team of external cybersecurity experts to investigate and assess the situation.” reads a notice published by the company. “As a result, we are now reasonably certain that there was a breach and that some information stored by our Company and/or our Group companies may have been compromised.”

Threat actors gained access to the network of the company and stole some data from its systems.

Now the BlackCat/ALPHV ransomware gang has added Seiko to the list of victims published on its data leak site.

The group published samples of some data allegedly exfiltrated from the company network, including passport scans and projects of new watches.

It is still unclear if the hackers have stolen company secrets or intellectual property, such as patented technologies used for its products.

The ransomware group states that the company has low security of its networks and products.
