Cook County Health Patients Affected by Cyberattack at Medical Transcription Firm
Cook County Health, which operates John H. Stroger, Jr. Hospital and Provident Hospital in Chicago, IL, has been informed by one of its business associates, Perry Johnson & Associates, Inc., (PJ&A) that patient data has potentially been compromised in a cyberattack. PJ&A provides medical transcription services to Cook County Health and has access to patients’ protected health information. PJ&A notified Cook County Health on July 21, 2023, that it was investigating a cyberattack, and confirmed on July 26, 2023, that the personal information of Cook County Health patients was stored on the compromised parts of its network. The forensic investigation confirmed that an unauthorized third party accessed the systems where patient data was stored in April 2023. It has been more than two months since Cook County Health was informed about the attack; however, PJ&A has yet to provide a final list of the affected patients and the compromised data, so notification letters have yet to be mailed. Cook County Health said the information likely compromised in the incident...
McLaren Health Facing Multiple Class Action Lawsuits over Ransomware Attack
Multiple lawsuits have been filed against McLaren Health over its August 2023 ransomware attack. The 15-hospital Michigan health system was attacked by an affiliate of the ALPHV/BlackCat ransomware group in August 2023, who claims to have exfiltrated the sensitive data of approximately 2.5 million patients. McLaren Health was added to the group’s data leak site on September 29, 2023, and threats were issued to publish the stolen data if the ransom is not paid. The threat actor also boasted about having an active backdoor into McLaren Health’s computer systems. The HIPAA Journal has confirmed that the group’s data leak site included patient names, patient ID numbers, genders, dates of birth, ages, addresses, Social Security numbers, race, language spoken, religion, pregnancy status, physician names, and other sensitive data. The attack prompted Michigan Attorney General Dana Nessel to issue a warning to current and former patients advising them to secure their medical and financial accounts and monitor for any attempted misuse of their personal information. “This attack shows, once...
CISA and FBI Update AvosLocker Ransomware Cybersecurity Advisory
The Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have issued an update on AvosLocker ransomware, which includes known indicators of compromise (IOCs), tactics, techniques, and procedures (TTPs), and detection methods associated with the AvosLocker ransomware variant. AvosLocker is a relatively new ransomware-as-a-service operation that was first identified in July 2021. While the group is not as prominent as LockBit Clop, and ALPHV (BlackCat), AvosLocker ransomware affiliates have compromised organizations across multiple critical infrastructure sectors. The group engages in exfiltration-based extortion, requiring the payment of a ransom to prevent the release of stolen data and for the keys to decrypt files. AvosLocker affiliates use legitimate software and open source tools during their ransomware operations. The group has been observed using Splashtop Streamer, Tactical RMM, PuTTy, AnyDesk, PDQ Deploy, and Atera Agent as backdoor access vectors, the open source networking tunneling tools Ligolo and Chisel, Cobalt Strike...
7 Ways AI Can be Used by Hackers to Steal Healthcare Data
Artificial Intelligence (AI) is transforming the delivery of healthcare in the United States. It is also responsible for one of the biggest threats to the delivery of healthcare in the United States – the theft of healthcare data. AI has been described as a double-edged sword for the healthcare industry. AI-based systems can analyze huge volumes of data and detect diseases at an early and treatable stage, they can diagnose symptoms faster than any human, and AI is helping with drug development, allowing new life-saving drugs to be identified and brought to market much quicker and at a significantly lower cost. However, AI can also be used by cybercriminals to bypass security defenses and steal healthcare data in greater volumes than ever before – potentially disrupting healthcare operations, affecting health insurance transactions, and preventing patients from receiving timely and effective treatment. This article discusses seven ways AI can be used by hackers to steal healthcare data and suggests ways that healthcare organizations can better prepare for future AI-driven and...
Why AI Will Increase Healthcare Data Breaches
Due to a lack of reporting transparency, it is difficult to accurately determine the true scale of healthcare data breaches and why they happen. Nonetheless, security experts are in agreement that the adoption of artificial intelligence (AI) by cybercriminals will lead to an increase in healthcare data breaches. To find out the scale of healthcare data breaches and why they happen, researchers tend to review the Department of Health and Human Services’ (HHS) Data Breach Portal – a database of data breaches affecting 500 or more individuals reported by healthcare providers, health plans, healthcare clearinghouses, and business associates subject to the requirements of the HIPAA Breach Notification Rule. However, according to the most recent HHS report to Congress, the data breaches that appear in the portal are just the tip of the iceberg. In calendar year 2020, the HHS’ Office for Civil Rights received 609 notifications of data breaches affecting 500 or more individuals, but there were 63,571 reports submitted to OCR about data breaches affecting fewer than 500 individuals....
