/in /tarafından

A cyberattack on UnitedHealth Group’s (UNH.N) technology unit, Change Healthcare, last year affected 192.7 million people, according to the U.S. Department of Health and Human Services (HHS). The company had previously estimated the breach impacted 190 million individuals.

Disclosed in February 2024, the attack—identified as the largest healthcare data breach in U.S. history—was carried out by hackers claiming to be part of the “Blackcat” ransomware group. The breach caused widespread disruptions in claims processing and affected patients and healthcare providers nationwide.

A UnitedHealth spokesperson confirmed, “The final total number of individuals impacted by the Change Healthcare cyberattack is approximately 192.7 million,” noting that state-by-state figures may vary.

Compromised data is believed to include health insurance member IDs, patient diagnoses, treatment records, social security numbers, and provider billing codes. The breach is now listed in HHS’s official database of healthcare data breaches maintained by its Office for Civil Rights.

Norway Attributes April Dam Cyberattack to Russian Hackers

Norway’s counter-intelligence chief has officially blamed Russian hackers for a cyberattack on a dam in Bremanger, western Norway, in April. During the incident, hackers briefly took control of the dam and opened a flood gate, releasing 500 litres (132 gallons) of water per second for four hours before authorities intervened. No injuries were reported.

Beate Gangaas, head of Norway’s PST security agency, said the attack is part of a rising pattern of operations by pro-Russian cyber actors aimed at causing fear and chaos among the population. She emphasized that the public disclosure is intended to raise awareness and prevent further attacks.

The Russian embassy in Oslo dismissed the claims as “unfounded and politically motivated.” Norway, a NATO member and major gas supplier, shares an Arctic border with Russia and has previously warned about threats to its energy infrastructure.

US Federal Judiciary Reports Sophisticated Cyberattacks on IT Systems

The Administrative Office of the U.S. Courts announced on Thursday that federal judiciary IT systems have been targeted by “recent escalated cyberattacks of a sophisticated and persistent nature.” The disclosure follows a Politico report claiming that the judiciary’s electronic case filing system was compromised in a sweeping hack, potentially exposing sensitive court data across several states.

According to Politico’s sources, the breach affected the federal case management system, including the Case Management/Electronic Case Files (CM/ECF) platform used by legal professionals to upload and manage documents, and the Public Access to Court Electronic Records (PACER) system, which provides public, paid access to certain case data.

While the Administrative Office’s statement did not confirm the full extent of Politico’s findings, it stressed that the judiciary is focusing on enhancing security measures and collaborating with courts to reduce the impact on litigants. The nature of the attacks and the actors behind them have not yet been disclosed.
