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.
Accenture, one of the world's largest IT consulting firms, has confirmed a data breach after a threat actor advertised stolen data for sale on a hacking forum. The seller claims to have taken about 35GB of source code along with RSA keys, SSH keys, Azure access tokens and storage keys, and configuration files, and shared a screenshot appearing to show them cloning an internal Azure DevOps repository. Accenture confirmed the breach but did not comment on the amount or type of data involved. If the stolen keys and tokens are valid, they could give attackers a path into Accenture's development systems or cloud infrastructure.
Medtronic has begun notifying about 3.8 million people that their data was exposed in the breach of its corporate IT systems earlier this year, giving a concrete scale to the ShinyHunters attack it first disclosed in April. The exposed information includes names, contact details, dates of birth, Social Security numbers, and health-related data, a more sensitive set than the company initially detailed. The intrusion, which the extortion group claimed involved around nine million records, was limited to corporate systems, with Medtronic saying its products, patient safety, and device networks were not affected. Affected individuals are being offered credit monitoring, and several class-action lawsuits have followed.
A Ransom-ISAC case study, built from a leaked negotiation chat and the blockchain trail, reconstructs how a US government entity quietly paid about $1 million to an extortion group called Kairos to keep stolen files from being published. Notably, Kairos never encrypted anything: there was no locker and no decryption key, just theft and the threat to leak, with special pressure applied to a folder of prosecutors' records. The month-long negotiation fell from a $3 million demand to a $1 million payment. The case reflects a broader shift, with roughly half of recent extortion now skipping encryption entirely, since data theft alone provides enough leverage.
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.
The US Department of Homeland Security has confirmed a breach of the Homeland Security Information Network, an unclassified but sensitive platform that federal, state, local, and private-sector partners use to share threat information and coordinate operations. The intrusion is believed to have happened between late May and early June, and according to reporting, the attackers targeted HSIN servers and an associated SharePoint collaboration system. DHS says it isolated the affected systems, that classified networks were not touched, and that the platform remains operational, but it has not attributed the attack or confirmed whether documents were stolen. Even without confirmed theft, compromising this coordination hub is operationally significant.
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.
Aflac Life Insurance Japan, a subsidiary of the US insurance giant Aflac, says attackers broke into its policyholder portal and stole personal data belonging to about 4.38 million customers and agents. The intruders accessed systems repeatedly between June 15 and June 25, when the breach was detected through a surge in traffic, and the company suspended affected systems in response. Exposed data includes names, addresses, phone numbers, dates of birth, gender, and insurance account details, plus premium payment account information for roughly 230,000 people; no credit card data was taken. Aflac says the incident is limited to its Japan systems and does not affect its US operations.
Nissan has disclosed that current and former employees' data was stolen after attackers exploited a zero-day flaw in Oracle PeopleSoft, the software it uses to manage payroll, tax, and personnel records. In a filing with California's attorney general, Nissan said Oracle informed it that the personnel records of hundreds of companies may have been taken. The attacks, tied to the extortion group ShinyHunters, exploited PeopleSoft vulnerability CVE-2026-35273 as a zero-day between late May and early June, primarily hitting education organizations, before Oracle issued mitigations. ShinyHunters has begun leaking stolen data, with Nissan joining victims that include the University of Nottingham and a US insurance regulator group.
Japanese telecom giant KDDI has disclosed a breach of an email platform it operates for itself and several internet service providers, potentially exposing the email addresses and passwords of up to 14.22 million mailboxes. KDDI detected the intrusion on June 17, blocked the attacker the same day, and traced the entry to a vulnerability in unnamed third-party software used by the email system. Six ISPs are affected, including JCOM, Nifty, and Biglobe, and the figure covers current, former, and inactive accounts. KDDI says some passwords were hashed or encrypted but has not said how many were stored in plaintext, and is urging all affected users to change their passwords.
