The NightSpire ransomware operation claimed to have breached Hyatt, offering a free download of 48.5 GB of data allegedly stolen from the Hyatt Place Chelsea New York hotel. Reported sample files include invoices and expense reports containing employee names, contact details, signatures, and partner information; researchers suggested the material may have been taken from an internal CMS and warned that any associated credential compromise could enable broader internal access and lateral movement.
Separately, Indian music streaming service Raaga reportedly suffered a breach affecting ~10.2 million users, with the dataset advertised for sale on underground forums and flagged via Have I Been Pwned. Exposed data reportedly includes names, emails, demographic/location fields, and passwords stored as unsalted MD5 hashes, increasing the likelihood of password cracking and downstream credential stuffing. Other items in the set are not incident-specific and instead cover general industry sentiment and reporting on privacy/attack-surface priorities (polling and commentary), as well as healthcare/ambulance-service breach statistics and crypto-scam reporting that reference breaches in passing rather than detailing a single, shared event.

The NightSpire ransomware operation allegedly claimed it breached the Hyatt Place Chelsea New York hotel and offered a free download of 48.5 GB of purportedly stolen data. Analysis of sample files indicated the leak included invoices and expense reports with employee names, contact details, signatures, and partner company information, possibly from the hotel's internal CMS.
After the Raaga compromise, the stolen database was reportedly advertised for sale on an underground hacking forum or cybercrime marketplace. Have I Been Pwned reportedly detected the breach after threat actors posted the alleged dataset.
Indian music streaming platform Raaga reportedly suffered a breach in December 2025 that exposed personal information tied to about 10.2 million users. The compromised data reportedly included roughly 10 million unique email addresses, names, demographic and location data, and passwords stored as unsalted MD5 hashes.
SOCRadar said the NightSpire ransomware group emerged in March 2025 and has mostly targeted organizations in the United States since then. This provides the campaign context for its later Hyatt claim.

Multiple organizations disclosed or were linked to **ransomware/data-extortion** activity with material operational or privacy impact. **Air Côte d’Ivoire** confirmed a cyberattack affecting parts of its information systems after **INC ransomware** claimed theft of **208 GB** and threatened to leak data, while the airline said it engaged the national CERT and external experts to contain impact and maintain flight operations. In the US healthcare sector, **University of Mississippi Medical Center (UMMC)** reported a ransomware incident that forced statewide clinic closures and disrupted access to **Epic** electronic medical records, prompting engagement with the **FBI** and **CISA** and use of downtime procedures to sustain patient care. Separately, **Conduent**’s earlier ransomware-linked breach continued to expand in scope, with breach notifications indicating at least **~25 million** people affected across multiple states and exposure of sensitive PII (including **SSNs** and health/insurance data). **Wynn Resorts** also confirmed an unauthorized party accessed and stole employee data after being listed by the **ShinyHunters** extortion group, with the company stating the actor claimed the data was deleted and that guest operations were not impacted. Other items in the set describe distinct, unrelated security events and broader threat research rather than the same incident: alleged data leaks involving **Burger King France** and **Wendy’s UK**; **Qilin** ransomware claims against a New York City transit union; Russian cyber operations against Ukraine’s power grid focused on intelligence collection; and a New Zealand healthcare application (**MediMap**) taken offline after apparent unauthorized access and **patient record tampering** (e.g., records marked deceased). Additional references cover threat research and trends (airline brand impersonation domains, edge-device exploitation telemetry, MuddyWater’s *Operation Olalampo*, Google Ads cloaking via **1Campaign**, freight/logistics phishing by “Diesel Vortex,” and various governance/AI/5G/quantum commentary), which provide context on the threat environment but do not substantively report on the same specific breach event.

Multiple organizations reported **unauthorized access and data exposure events** affecting large populations, with several incidents tied to third-party systems or business associates. The Minnesota Department of Human Services notified nearly **304,000** people after a user associated with a licensed healthcare provider accessed demographic records in the *MnChoices* system (managed by vendor **FEI Systems**) beyond what was authorized; most impacted records were demographic data, with a smaller subset including some medical information and, for some, the last four digits of SSNs. Monroe University reported a **December 2024** intrusion with data exfiltration affecting about **320,973** individuals, with exposed data potentially including SSNs, government IDs, financial account information, and health/insurance data; notification letters began in early January 2026. Separately, Mid Michigan Medical Billing Service disclosed a **March 2025** cyberattack that exposed PHI for **28,185** individuals across healthcare clients, and VillageCareMAX reported a breach involving business associate **TMG Health** (details referenced as part of a broader business-associate breach update). Other items in the set describe distinct, unrelated security stories rather than the same incident: an underground-market sale of **Raaga** user data (10.2M records, including passwords stored as **unsalted MD5 hashes**), a settlement in litigation tied to the **Veradigm** breach (over 2M patients; **$10.5M** class-action settlement), and a **ransomware** incident at **Valley Eye Associates** where a group identified as **Qilin** claimed exfiltration (139 GB) and published data. Additional references include commentary on UK government handling of an **Afghan data breach** (spreadsheet emailed outside the MoD and use of an injunction) and broader analysis of healthcare breach trends and UK ambulance-service breach reporting; these provide context but do not describe the same specific event as the Minnesota DHS or other named incidents.

Rome’s **La Sapienza University** shut down network systems as a precaution after a cyberattack caused widespread disruption and left its website offline; Italian media attributed the incident to a suspected ransomware operation linked to pro-Russian actor **Femwar02**, with reported tradecraft resembling **Bablock/Rorschach**-style fast encryption. Separately, Romania’s national oil pipeline operator **Conpet** reported a cyberattack that disrupted corporate IT and took down `www.conpet.ro` while leaving **OT/SCADA** and pipeline transport operations unaffected; **Qilin** claimed responsibility, alleging theft of nearly **1TB** of data and posting sample documents (including financial data and passport scans) to support extortion claims. In the U.S., government services contractor **Conduent** faced expanding breach impact from its January 2025 ransomware incident, with notifications indicating exposure potentially reaching **dozens of millions**; reported affected data includes **names, Social Security numbers, and medical/health insurance information**, with at least **15.4M** impacted in Texas and **10.5M** in Oregon per state disclosures. Additional healthcare-sector disclosures included a ransomware-linked intrusion at **Insightin Health** (unauthorized access in September 2025; **Medusa** claimed exfiltration of **378GB**) and a separate compromise at **Clinic Service Corporation** (August 2025 access window), while **Central Ozarks Medical Center** reported a criminal cyberattack affecting **11,818** individuals with exposure of PHI/PII (including SSNs and financial/insurance data). Other items in the set were not incident-specific: an **HHS-OIG** audit describing web application security weaknesses at a large hospital, and general guidance/education pieces on the value of medical records to attackers and **CISA** insider-threat guidance.
