Spain arrests 34 cybercriminals who stole data of 4 million people (


Following 16 targeted searches, the Spanish National Police have arrested 34 individuals believed to have been behind a criminal organisation that stole and monetised the data of millions. Alongside firearms and hand weapons, four high-end cars, and 80,000 euros in cash, the police raids discovered a computer database containing the information of 4,000,000 people. Spanish police have stated that the arrested individuals have been linked to numerous email and SMS phishing scams; without a fixed modus operandi.

Following thousands of complaints and a common pattern of trickery, the investigation into the group's activities began in early 2023. The total profit that the group has made from reselling stolen data is believed to be €3,000,000. With those identified as the gang's leaders already behind bars, there will be an effort over the next few months to identify even more of the gang's affiliates. (Bleeping Computer)

Seiko's most recent statement has confirmed that the total number of compromised user records was 60,000, with stolen data including Seiko Watch Corporation (SWC) user data, contact details, employee application information, and details of current and former employees at both Seiko Group and Seiko Watch Corporation.

Fortunately, credit card information remains secure, and Seiko has now implemented improved security controls, such as EDR and MFA. A Seiko statement read "“We sincerely apologise for any inconvenience this attack on our data servers may have caused or may yet cause. We have begun reaching out to each of the affected parties individually, and if any further leaks are discovered, we will, to the best of our ability, continue to respond to each affected party on an individual basis.”
