BleepingComputer reports that Western Digital has begun notifying its customers regarding the theft of limited personal data following a cyberattack in March.
Threat actors were able to compromise on or around March 26 a Western Digital database copy with the online store customers' personal data, including their names, email addresses, billing and shipping addresses, hashed and salted passwords, and partial credit card numbers, said Western Digital in its data breach notification letter, which also noted the temporary suspension of online store account access, with restoration expected by the week of May 15.
Western Digital was reported by TechCrunch to have been attacked by an unnamed hacking operation, which claimed to exfiltrate 10TB worth of data and leveraged ALPHV/BlackCat ransomware group's data leak site for extortion purposes despite claiming that they were not affiliated with the gang.
While further threats of leaking Western Digital's data were made on April 28, attackers have not released more stolen data, indicating continued extortion efforts.
Western Digital: Customer data compromised in March attack
BleepingComputer reports that Western Digital has begun notifying its customers regarding the theft of limited personal data following a cyberattack in March.
Almost 75% of all reported cyberinsurance claims during the first half of this year were attributed to business email compromise attacks, ransomware incidents, and fund transfer fraud, with average ransomware claim losses totaling $353,000.
Such a development comes months after National Public Data admitted the exposure of a database stolen from a December 2023 breach beginning in April, which was then followed by civil penalties being sought by over 20 states as well as potential fines from the Federal Trade Commission.
Investigation into the incident revealed the exfiltration of personal data from Casio and its affiliates' permanent and temporary employees, business partners, customers, and interviewed prospects for employment, as well as contracts with business partners.
