Breach

After initially publishing data purportedly from Kadokawa in late June — which the firm confirmed to include internal corporate information and business partner details — BlackSuit was discovered by cybersecurity researcher HackManac to have updated its darknet site with additional stolen data on Tuesday.

Over 5.2 million files, or 6.6 TB of data, from ICBC London have been allegedly exfiltrated by Hunters International, which has threatened to expose all the stolen data on Friday should the bank refuse to fulfill its demands.

Russian state-sponsored threat group Coldriver has been suspected by the Free Russia Foundation of being behind the intrusion, which involved the targeting of several entities to exfiltrate internal documents, grant reports, and other correspondences in retaliation against pro-democracy Russians

While Avis has provided the total number of individuals affected by the incident in its filing with the Office of the Maine Attorney General, it has not specified the nature of the intrusion as well as its impact on employees.

The payment processing service said credit card information was accessed in June 2024.

Despite immediately acting to block the infiltration of the targeted business application, attackers' access between Aug. 3 and Aug. 6 enabled the exfiltration of individuals' names and other sensitive details.

Included in the information exfiltrated as part of the breach were individuals' names, birthdates, Social Security numbers, Medicare account numbers, addresses, and health insurance details, said the Centers for Medicare & Medicaid Services and the Wisconsin Physicians Service Insurance Corporation.

Immediate withdrawal and deposit takedowns, as well as notifications to the FBI's Internet Crime Complaint Center and the Singaporean police have been conducted by Penpie following the theft on Tuesday.
