Suno AI Music Generator Data Leak
A data leak at the AI music generator Suno, which occurred in November 2025, became public in July 2026. The breach exposed data from over 55 million unique email addresses and, for users who registered with their phone numbers, those numbers as well. A small portion of the dataset also included payment processor Stripe data, leading to the leak of names, physical addresses, purchase amounts, and certain credit card details (card type, expiration date, and last four digits) for tens of thousands of users. Suno confirmed it does not have access to full credit card numbers via Stripe.

SR Bancorp's Internal Audit Provider, Mercadien, Experiences Data Security Incident
Mercadien, P.C. CPAs, an internal audit service provider for SR Bancorp and Somerset Regal Bank, reported a data security incident on July 10, 2026. An unauthorized actor accessed and acquired files from Mercadien's servers containing sensitive customer data belonging to Somerset Regal Bank. The compromised data included customer names, Social Security numbers, account numbers, identification documents, and dates of birth. Importantly, SR Bancorp confirmed that its own business systems, payment systems, customer access to accounts, and core information technology infrastructure were not affected by the incident. The bank is coordinating with Mercadien to provide notifications to affected customers as required by federal and state laws and regulatory guidance. While the incident exposes customers to potential identity theft and fraud, SR Bancorp currently assesses the financial impact as immaterial to its consolidated financial condition or results of operations. This incident highlights the significant risks associated with third-party vendors handling sensitive customer information.
SR Bancorp Discloses Data Security Incident at Internal Audit Provider Mercadien, Exposing Somerset Regal Bank Customer Data
SR Bancorp, Inc. reported a data security incident on July 10, 2026, involving its internal audit service provider, Mercadien, P.C. CPAs. An unauthorized actor accessed and acquired files from Mercadien's servers that contained sensitive customer data belonging to Somerset Regal Bank. The compromised information included customer names, Social Security numbers, account numbers, identification documents, and dates of birth. Importantly, SR Bancorp confirmed that the bank's own business systems, payment systems, customer access to accounts, and core information technology infrastructure were not directly impacted or disrupted by this incident. The company is coordinating customer notifications through Mercadien as required by applicable federal and state laws and regulatory guidance. While the incident exposes SR Bancorp to regulatory notification requirements, reputational risk, and potential legal liability, the company has initially assessed the financial impact as immaterial to its consolidated financial condition or results of operations. However, this assessment could change if the data is published or misused, or if further cybersecurity incidents occur. This event highlights the inherent risks associated with third-party vendors handling sensitive customer information.

Xsolis Data Breach Exposes 1.4 Million Patient Records Across Eight Health Systems
A targeted phishing attack on healthcare AI company Xsolis has exposed the data of at least 1.4 million patients across eight U.S. health systems. Xsolis develops utilization management and care coordination technology widely used by hospitals and health systems. This breach now ranks among the most significant healthcare vendor cyberattacks of 2026. The U.S. Department of Health and Human Services (HHS) confirmed the patient impact figure on June 22, after Xsolis filed its breach report on June 5. Moreover, legal action over the incident has already been filed in at least one case, signaling growing accountability pressure on AI vendors handling sensitive patient data. The breach did not begin with the disclosure. Instead, the unauthorized access occurred months earlier. On January 20, 2026, an unidentified actor accessed portions of Xsolis’s IT environment. The attacker then acquired a limited number of files from within the system. Xsolis did not report the incident to HHS until June 5 — roughly four and a half months after the initial intrusion. This delay has drawn scrutiny. Furthermore, Hendrick Health in Abilene, Texas, faced a separate lawsuit specifically citing delayed patient notification as a key concern. Xsolis has stated the company is not currently aware of any misuse of the stolen data. However, the company has declined to specify which types of patient information were exposed. A spokesperson confirmed Xsolis is notifying affected individuals but is not commenting beyond its June 5 public statement. The following health systems have confirmed involvement in the Xsolis data breach : Rochester Regional Health — Rochester, N.Y. Together, these eight organizations collectively serve patients across six states. Consequently, the breach spans a wide geographic footprint — from the Pacific Northwest to the Southeast and Midwest. Xsolis took several steps after discovering the breach . First, the company reported the incident to HHS on June 5. Next, it began notifying affected patients directly. Additionally, Xsolis released a formal public statement through PR Newswire acknowledging the security incident. However, critics note that the five-month gap between the January intrusion and the June disclosure raises serious questions. Under HIPAA, covered entities and business associates generally must report breaches within 60 days of discovery. Health systems and regulators are now examining whether this timeline met legal standards. Why This Breach Matters for Healthcare AI This incident highlights a critical vulnerability in modern healthcare operations. Health systems increasingly rely on third-party AI vendors for functions like utilization management and care coordination. As a result, these vendors hold highly sensitive patient records — making them attractive targets for cybercriminals. Phishing attacks remain the leading method hackers use to gain unauthorized access. Notably, a single successful phishing email at a vendor like Xsolis can cascade into a breach affecting millions of patients at multiple health systems simultaneously. Third-Party Risk in Healthcare Is Growing Third-party vendor breaches now account for a rising share of healthcare data incidents. Therefore, health systems that outsource clinical and operational functions to AI companies must treat vendor cybersecurity as a direct extension of their own risk management. Regulators, including HHS’s Office for Civil Rights, actively scrutinize business associate agreements (BAAs) and breach timelines. Health systems found to lack adequate vendor oversight face fines and reputational harm alongside their vendors. Health system leaders should act quickly when a vendor breach occurs. First, they must verify whether their organization was part of the affected vendor’s client base. Next, they should request a full incident report from the vendor, including the timeline and scope of data access. Additionally, health systems must assess their own HIPAA obligations independently. Even when a vendor like Xsolis handles patient notifications, the covered health system retains compliance responsibility. Going forward, health systems should strengthen third-party risk programs. Key actions include conducting annual security assessments of all AI and health IT vendors, requiring vendors to carry cyber liability insurance, and including clear breach notification timelines in every BAA. Furthermore, phishing awareness training must extend beyond a health system’s own staff. Health systems should require vendors to demonstrate regular employee security training as a contract condition. Ultimately, a vendor’s security posture directly affects every patient record that vendor touches. Vendor breaches, regulatory shifts, and the governance gaps in between. Here's what happened this month in third-party risk management news. Financial institutions are legally accountable for what their vendors do with customer data. Outsourcing a function doesn't outsource the liability that comes with it — a principle that runs through GLBA Safeguards Rule requirements, state privacy laws, and open banking obligations under Part 1033. Vendor contracts need to do more than check a compliance box: they should specify permitted data uses, require breach notification within 24–48 hours, include audit rights, and address AI governance for any vendor using automated decision-making. Fourth-party risk also warrants explicit contract language requiring vendors to disclose and flow down obligations to their own subcontractors. A phishing attack on a healthcare AI vendor exposed 1.4 million patient records. Xsolis, which provides AI-powered utilization management to hospitals and health insurers, was breached through a single phishing email, exposing Social Security numbers, health insurance details, and medical treatment records across seven major hospital systems including Mayo Clinic. At least one organization — Rochester Regional Health — had ended its relationship with Xsolis in 2021, yet its patient data was still in scope at the time of the breach. Most of the 1.4 million affected had no idea the vendor held their information at all. Third-party vendor incidents now account for 58% of all healthcare data breaches, and this case is a concrete reminder that data deletion at offboarding is a risk control, not an administrative afterthought. The Klue breach reached LastPass customer data. Attackers used OAuth tokens stolen from Klue to access LastPass's Salesforce environment, exposing customer names, contact details, and support case records. Password vaults were unaffected, but the stolen data is enough to fuel targeted phishing. Fourth-party risk in practice: a vendor relationship several steps removed still produced direct customer harm. How to Avoid Common Third-Party Risk Management Mistakes
