Hackers Compromise Telecoms Providers Targeting Government Officials
A joint statement from the FBI and CISA addresses a nation state threat actor targeting telecommunications infrastructure with the objective of intercepting private communications of government officials. Threat actors “compromised networks at multiple telecommunications companies to enable the theft of customer call records data” which affected a small number of individuals who are involved primarily in government or political activities. They also stole “certain information that was subject to U.S. law enforcement requests pursuant to court orders.”
57 Million People Affected by Hot Topic Data Breach
HaveIBeenPwned (HIBP) added the retailer “Hot Topic” to their list of affected websites. Discovered in October 2024, the breach contains 56,904,909 compromised accounts with Dates of birth, Email addresses, Genders, Names, Partial credit card data, Phone numbers, Physical addresses, Purchases, Salutations.
The threat actor boasted on BreachForums that the data breach included 350 million customers information from Hot Topic, Torrid and Box Lunch and was attempting to sell the data for $20,000 as reported on BleepingComputer. But this proved to be an inflated number.
Idaho Hacker Sentenced to 10 Years for Extorting U.S. Healthcare Providers
Robert Purbeck, a 45-year-old from Idaho, was sentenced to ten years in prison for hacking 19 U.S. organisations and stealing personal data of over 132,000 people. Known online as "Lifelock" and "Studmaster," Purbeck bought access to servers on the darknet, stealing data from a medical clinic and a police department in Georgia. He extorted a Florida orthodontist in 2018, threatening to sell patient data. The FBI found data of over 132,000 people during a 2019 raid. Purbeck pleaded guilty to unauthorised computer access and will also serve three years of supervised release and pay over $1 million in restitution.
