Data from a breach at cancer-screening company Exact Sciences, now part of Abbott, was indexed by Have I Been Pwned with about 10.9 million unique email addresses. The extortion group ShinyHunters claimed the intrusion, saying it reached internal legacy systems and then pivoted from a corporate single-sign-on account into connected cloud services such as Microsoft 365, Salesforce, and others to steal data. It is part of a wider ShinyHunters wave hitting medical-technology companies. Abbott is investigating and disputed the attacker's characterization of some data. The pattern, one stolen sign-on unlocking many linked services, is now a recurring route to large healthcare breaches.
Analog Devices, a major US semiconductor maker, confirmed in a securities filing that an unauthorized party accessed some internal systems and exfiltrated files in a June intrusion, while saying operations were not affected. The company has not named who was responsible. Days before the filing, an extortion group calling itself ExfilSquad listed Analog Devices on its leak site and claimed to hold about 570,000 customer records with personal information and home addresses, but Analog Devices has not linked the June breach to that group, and the claim is unverified. The filing also noted a second, separate security issue unrelated to the June intrusion.
Dental benefits administrator DentaQuest, part of Sun Life, is notifying more than 23 million people that their personal and health information was stolen in a May 2026 network intrusion. The company found unauthorized access on May 20 and determined attackers were in its network between May 17 and 20. Exposed data includes names, addresses, Social Security numbers, member, Medicaid, and Medicare identifiers, and dental and vision health details such as diagnoses, treatments, and billing. The extortion group ShinyHunters claimed responsibility and leaked roughly 234GB. DentaQuest has confirmed at least 15 million affected, with independent analysis putting the figure above 23 million, and is offering two years of monitoring.
Mount Royal University in Calgary has confirmed that attackers breached its network in June, stole data from its file storage systems, and then deleted the files to hinder recovery, as the hackers now publicly claim the attack. The intrusion, detected around June 18, disrupted phones, the university website, and other systems. The affected storage held academic material such as assignments and research, but the university acknowledges some students and staff may have kept personal information there, and a separate departmental drive was also wiped. Mount Royal is notifying affected individuals and offering credit monitoring to current and recent employees, though not to students.
The extortion group ShinyHunters has published data stolen from Moody Bible Institute, a Chicago-based Christian college, after a "pay or leak" campaign. Have I Been Pwned indexed more than 2.3 million unique email addresses along with names, physical addresses, phone numbers, and dates of birth belonging to students, alumni, donors, and supporters. ShinyHunters claimed a much larger haul spanning enrollment, donor, payroll, and communications systems, and some reporting ties the intrusion to the same ShinyHunters campaign that exploited an Oracle PeopleSoft flaw. Most of the leaked email addresses had already appeared in earlier breaches, raising the risk of credential stuffing and targeted phishing.
Medical device maker Medtronic has begun notifying customers that their personal data was exposed in a breach of its corporate IT systems earlier this year, an attack claimed by the extortion group ShinyHunters. Medtronic noticed unusual activity in mid-April and its investigation found that an unauthorized actor had access between April 13 and 19. ShinyHunters claimed to hold roughly nine million records containing personal and internal corporate data, and Medtronic did not pay, with its listing later removed from the group's leak site. The company says its products, patient safety, and the networks running its medical devices were not affected, crediting separation between corporate and clinical systems.
Food distribution giant Sysco was hit by the extortion group ShinyHunters in a "pay or leak" attack, and after the company did not pay, the stolen data was published. Have I Been Pwned has indexed 2,691,852 unique email addresses belonging to staff and customers, alongside what is described as largely corporate contact information. The breach fits ShinyHunters' sweeping 2026 campaign against large enterprises, which has typically relied on social engineering and compromised SaaS integrations rather than software exploits. Exposed business contact data is useful for convincing, targeted phishing aimed at Sysco's staff, customers, and partners.
The extortion group ShinyHunters has published data stolen from Madison Square Garden Sports, owner of the New York Knicks and Rangers, after the company did not pay. Have I Been Pwned indexed 9,796,738 unique email addresses spanning staff and customers, alongside extensive personal, employment, and customer-relationship records including names, addresses, phone numbers, and some dates of birth. Reporting on the leak describes an internal "Talent" file profiling former players, executives' family members, and celebrities, in some cases with so-called threat assessments. The intrusion reportedly began with voice-phishing of staff, the same social-engineering pattern behind ShinyHunters' wider 2026 campaign against large enterprises.
Tata Electronics, the Indian manufacturer that assembles roughly a third of Apple's iPhones in India, has confirmed a cyberattack affecting part of its IT systems after the extortion group World Leaks began leaking stolen data. The group claims to have taken around 200,000 files, including confidential Apple and Tesla manufacturing and component design documents, internal emails, years of event logs, and copies of employee passports, some belonging to foreign nationals. Researchers say the data has been on the dark web since at least June 10, and a ransom was demanded. World Leaks, a rebrand of the Hunters International group, also claimed breaches at Nike and Dell.
Eastman Kodak has confirmed that an unauthorized third party gained temporary access to a limited amount of company data, after the extortion group ShinyHunters listed the firm on its dark-web leak site. ShinyHunters claims it stole more than 2.2 million records containing customer personal information and internal corporate data, and set a leak deadline of June 18, though it has released no proof and Kodak has not verified the figure. Kodak, now mainly a B2B manufacturing and technology company, says it engaged outside experts and law enforcement and sees no threat to operations. The breach fits ShinyHunters' prolific 2026 data-theft campaign.
