220 million traveler records exposed in Vietnam-linked APIS leak
Vietnam-linked APIS Elasticsearch leak exposed 220 million passenger and crew records with passport numbers and flight details spanning 2017 to 2026.
Kinryū Labs discovered an exposed Elasticsearch cluster named 'pax-info' holding 210,318,069 passenger records and 10,465,631 crew records (roughly 107 GB across 29 indices) hosted in Viettel-assigned IP space in Hanoi. The database, apparently operated by a Vietnamese organization, was reachable via a chain of two misconfigurations: a cloud-based path that bypassed an HTTP 401 block and acceptance of default credentials. Exposed data included names, dates of birth, nationalities, passport numbers, and detailed flight information for travelers of many nationalities from January 2017 to April 2026. Access was remediated on June 8 after Kinryū Labs notified Vietnamese authorities, airlines, and CERTs, with Singapore Airlines' security team helping coordinate the response; it remains unknown whether any data was copied by malicious actors.

Hacker claims millions of records stolen from corporate Azure tenants
Threat actor TheHatman claims millions of employee records stolen from Azure tenants of nine Fortune 500 firms, including McDonald's, Vodafone, Kyndryl, and TCS.
A threat actor known as TheHatman posted large internal employee directories on cybercrime forums over the past week, claiming each was pulled directly from the victim organization's Azure tenant. McDonald's tops the list at roughly 1.7 million records, followed by TCS (~800,000), Vodafone (~425,000), and HCL (~250,000), with IHG, Kyndryl, Gap, Hexaware, and Wyndham also named. Hudson Rock found samples consistent with standard Azure directory exports and suspects infostealer-derived credentials rather than a systemic Azure zero-day. TCS filed a statement with the Bombay Stock Exchange saying it found no credible evidence of a breach and the data appears over four years old.

Chess.com Leak Exposes 7.3 Million Users — Evidence Points to Scraping
A free 15.5 GB leak exposed 7.3 million Chess.com user records; analysis suggests large-scale scraping via find-friends rather than a server breach.
A 15.5 GB dump containing 7,337,395 Chess.com records appeared on leak forums posted by user V0idix at no cost. Ransomnews confirmed the data is genuine by validating embedded v1 UUID timestamps against registration dates, but found daily-batch collection over nine days and ~7.4% duplicate records, pointing to scraping. The schema includes emails, ratings, subscription tiers and internal Google Ad Manager audience segments not exposed in the public API, and contains no passwords or payment data. Chess.com reported a similar 828,000-record 2023 leak from find-friends abuse and said then that it was not a breach.

Massive Vietnam-Linked APIS Database Exposes Passport and Flight Data
Exposed Vietnam-linked APIS database held 220.8 million passenger and crew records with passport and flight data from January 2017 to April 2026.
Kinryū Labs discovered an exposed Elasticsearch cluster named 'pax-info' containing 220.8 million passenger and crew records, about 107 GB across 29 indices, hosted on IP space assigned to Viettel in Hanoi. The records include names, birth dates, nationalities, passport numbers, and detailed flight information from airlines across Asia-Pacific, Europe and the Middle East. Researchers reported the exposure on June 3 and the database was secured by June 8 with Singapore Airlines coordinating; no evidence of theft was found, but missing server logs mean access cannot be ruled out.

McDonald’s Employee Data Appears in Leak, Seller Claims 1.7M Records Stolen
A seller offers 1.7 million McDonald's employee records allegedly taken from its Azure tenant via compromised credentials; an 8,000-row sample verifies as genuine.
A forum seller named TheHatman posted an 8,000-row sample of McDonald's employee directory data, claiming a 1.7 million-record haul pulled directly from the company's Azure tenant using compromised credentials. Ransomnews analysis found authentic Entra ID export artifacts, including genuine domains, tenant-internal addresses, encoding errors, and truncated HR fields, but could not verify the data's age or the 1.7 million figure. The same seller listed nine datasets in 16 days covering about 3.6 million records across McDonald's, Vodafone, Gap, hotels, and IT outsourcers, suggesting infostealer-driven credential resale. No passwords or hashes appear in the sample, so the primary risk is social engineering.
