CISA Shares Vulnerabilities and Misconfigurations Exploited by Ransomware Gangs
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) maintains a Known Exploited Vulnerabilities (KEV) Catalog, which includes a list of all common vulnerabilities and exposures (CVEs) that are known to have been exploited by malicious actors. In January, CISA launched its Ransomware Vulnerability Warning Pilot (RVWP) program, under which critical infrastructure organizations are warned when Internet-accessible devices and systems are discovered on their networks that have unpatched vulnerabilities that could be exploited by ransomware actors. Organizations cannot address vulnerabilities on their networks that they are unaware of. The RVWP program aims to shine a light on security blind spots to allow organizations to take action and address the vulnerabilities before they are exploited in ransomware attacks. Under this program, CISA has already issued warnings to more than 800 organizations about unpatched vulnerabilities on their networks. Last week, CISA published two new resources to help network defenders combat ransomware campaigns. The KEV Catalog has been...
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...
