ShinyHunters leaks DentaQuest archive after failed extortion
Reporting on June 7 said ShinyHunters published a 234 GB archive allegedly stolen from DentaQuest after extortion talks failed. DentaQuest said on June 2 that it had contained unauthorized access to a limited part of its network and was working with cybersecurity experts, forensic investigators, and law enforcement. Coverage says the leak could affect about 2.6 million people and includes names, dates of birth, contact details, addresses, health insurance information, and some Medicaid IDs.
Why it matters
The incident combines large-scale health-data exposure with public extortion, increasing identity-theft and compliance risk for millions.

Security Affairs coverageNYC Health + Hospitals faces breach lawsuit
A proposed class action filed in Manhattan federal court alleges NYC Health + Hospitals exposed data on millions of patients, staff, and family members after unauthorized system access. The complaint says the exposure window ran from Nov. 25, 2025, to Feb. 11, 2026, and that the hospital system realized an actor had accessed systems on Feb. 2 before taking remediation steps. Plaintiffs say exposed data may include Social Security numbers, medical records, credit card information, geolocation, fingerprints, government IDs, diagnoses, prescriptions, and insurance details.
Why it matters
The case could force more disclosure on the scope and handling of one of the year's largest alleged healthcare exposures.

Roosevelt Island Daily coverageMandiant details Silent Ransom Group law-firm campaign
Mandiant said the Silent Ransom Group, also tracked as UNC3753, Luna Moth, and Chatty Spider, targeted dozens of U.S. legal and professional-services organizations from January through May 2026. The campaign used invoice-themed phishing emails followed by phone calls impersonating IT staff to push employees into remote-support sessions on Teams, Zoom, Quick Assist, or Terminal Services. Attackers then installed remote-management tools, searched for sensitive documents, and often issued ransom demands within about 30 minutes, with threats to contact employees and clients.
Why it matters
It shows a fast-moving social-engineering playbook aimed at high-value data stores in sensitive professional firms.
