NorthBay Healthcare Notifies 569K Individuals About February 2024 Data Breach
NorthBay Healthcare Corporation, a nonprofit healthcare system that operates two hospitals – NorthBay Medical Center & NorthBay VacaValley Hospital – and multiple primary care locations in California, has recently announced a data breach involving the personal and protected health information of 569,012 individuals. According to the notification sent to the Maine Attorney General, suspicious activity was identified within its network on February 23, 2024. An internal investigation was launched, law enforcement was notified, and third-party cybersecurity experts were engaged to assist with the investigation. The notification letter confirms that a threat actor gained access to its network on January 11, 2024, and the unauthorized access continued until April 1, 2024, more than 6 weeks after the security incident was detected. The notification letter does not explain why it took so long to eject the unauthorized third party from its network. The investigation confirmed that the threat actor had access to files containing patient data. The file review confirmed that...
2024 Healthcare Data Breach Report
Large healthcare data breaches continue to be reported to the Department of Health and Human Services (HHS) Office for Civil Rights (OCR) in high numbers. As of January 28, 2025, the OCR data breach portal shows 725 data breaches of 500 or more records in 2024, the third consecutive year that more than 700 large data breaches have been reported to OCR. That total could well change, as there is usually a delay in adding data breaches to the breach portal, as OCR conducts checks of all breach reports before adding them to the breach portal. The current figures indicate a slight (2.95%) year-over-year reduction in healthcare data breaches, 22 fewer data breaches than 2023’s record-breaking number of data breaches. As the above bar chart shows, healthcare data breaches have historically increased each year, with the biggest annual increases between 2018 and 2021, when large data breaches increased by 93.7%, primarily due to a sharp increase in hacking and ransomware incidents. Between January 1, 2028, and September 30, 2023, OCR reported a 278% increase in ransomware attacks, and...
Study Reveals 88% of Companies Experienced a Ransomware Attack Last Year
A recent survey conducted by the Ponemon Institute on behalf of Illumio, a zero-trust segmentation platform provider, revealed 88% of surveyed organizations had experienced one or more ransomware attacks in the past 12 months, highlighting the extent to which ransomware groups are running riot and the difficulty organizations have defending against attacks. The survey was conducted on 2,547 IT and cybersecurity professionals in the United States, United Kingdom, Germany, France, Australia, and Japan, including 7% of respondents from the healthcare and pharmaceutical sectors. The findings of the survey were published in Illumio’s Global Cost of Ransomware Report. On average, organizations spent almost one-third of their IT budget on ransomware defense, yet 88% still experienced a ransomware attack, showing it is not how much money is devoted to ransomware defense but how that information is spent that is important. Multifactor authentication, automated patching, intrusion prevention/detection systems, email security, and segmentation/micro-segmentation were the most common...
Mulkay Cardiology Consultants Agrees Settlement to Resolve Ransomware-related Lawsuit
In Early November 2023, Mulkay Cardiology Consultants in New Jersey announced it had fallen victim to a ransomware attack that involved unauthorized access to the protected health information of up to 79,582 individuals. Legal action was taken by victims of the breach and a settlement has been agreed to bring the litigation to an end. The forensic investigation determined a threat actor had access to its network from September 1 through September 5, 2023, and exfiltrated files containing patient data. The stolen data included names, addresses, dates of birth, Social Security numbers, driver’s license numbers or state IDs, medical treatment information, and health insurance information. The NoEscape ransomware group claimed responsibility for the attack and started leaking the stolen data on its dark web data breach site, although the listing was later removed. Multiple class action lawsuits were proposed in response to the breach which were consolidated into a single lawsuit – Wilkins, et al. v. Mulkay Cardiology Consultants at Holy Name Medical Center PC, et al – which was...
More Than 1.7 Billion Individuals Had Personal Data Compromised in 2024
There was a slight fall (1%) in data compromises in 2024, although only 44 fewer than last year’s record-breaking total. There was not a corresponding fall in the number of victims of data compromises, with victim notices increasing by 312% from 419 million notices in 2023 to 1,728,519,397 in 2024, according to the 2024 Annual Data Breach Report from the Identity Theft Resource Center (ITRC). The vast majority of data compromises (80%) in 2024 were caused by cyberattacks, with those incidents accounting for 93% of breach notices, followed by system and human error, supply chain attacks, and physical attacks. The massive increase in victim notices was largely due to a handful of mega data breaches. In 2024, 6 data breaches were reported that each involved more than 100 million records. While the data breach at Change Healthcare was the largest healthcare data breach in history, involving 190 million compromised healthcare records, it only ranked in third place last year due to two colossal data breaches. A breach at Advance Auto Parts Inc. took second spot with 380 million consumer...
