Ernst and Young says client tax documents were stolen from a support platform

Ernst & Young is notifying clients of a breach at a third-party IT service management platform used by staff supporting its tax practice. Support tickets submitted through the platform could include attached documents containing client tax information, and the firm says an unauthorized third party accessed the platform between March 28 and April 12 and downloaded documents belonging to a number of clients. EY detected the activity on April 23, roughly two weeks after it stopped, and filed breach notifications with the California Attorney General in July. The exposed data includes personal and financial information used to prepare tax filings.

Check
EY tax clients should watch for a notification letter, monitor financial accounts and credit, and treat unexpected messages referencing their tax filings or the firm as likely phishing.
Affected
EY tax clients whose documents were attached to support tickets; personal and financial information used to prepare tax filings was downloaded, which supports identity theft and convincing targeted phishing.
Fix
Affected clients should consider a credit freeze and monitor accounts. Organizations should limit what sensitive data staff attach to helpdesk tickets, set retention limits on attachments, and assess vendor security.

Coca-Cola's Fairlife halts US dairy production after a ransomware attack

Coca-Cola disclosed in a securities filing that a ransomware attack on its Fairlife dairy subsidiary has disrupted operations and temporarily suspended production across the United States. The company said Fairlife detected unauthorized access to some systems, including production-related systems, and that it activated incident response and business continuity plans, brought in outside experts, and notified law enforcement. It says product quality and safety were not affected, and Canadian operations continue. The full impact is still being investigated, and no ransomware group has been named. Ransomware at food and beverage producers has caused weeks-long shutdowns and empty shelves in past incidents.

Check
Manufacturers should review their ability to keep production running during a cyberattack, confirm that business and production systems are segmented, and test backups and incident-response and continuity plans against a ransomware scenario.
Affected
Manufacturers and food and beverage producers whose production depends on connected systems; a ransomware attack can force a full production halt even when product safety is unaffected, as with Fairlife's US suspension.
Fix
Segment production and business networks, maintain tested offline backups, enforce phishing-resistant MFA on remote access, rehearse recovery, and prepare business-continuity plans that keep critical operations running during a systems shutdown.

Lidl notifies online shop customers of breach at a service provider

Discount supermarket chain Lidl has notified online shop customers in Germany, Belgium, and the Netherlands of a data breach that stemmed from a hack at one of its service providers rather than Lidl's own systems. According to the company, the exposed information involves customer contact and order-related details, while payment card data was not affected. The incident is another example of third-party or supply-chain risk, where attackers compromise a vendor to reach a larger brand's customer data. Even without financial data, the exposed details can fuel convincing phishing and scams that impersonate Lidl, especially messages referencing real orders to make fraudulent requests look legitimate to shoppers who recently used the online shop.

Check
Lidl online shop customers in the affected countries should watch for the notification, be wary of messages referencing Lidl or their orders, and avoid clicking links or sharing details in unsolicited messages.
Affected
Lidl online shop customers in Germany, Belgium, and the Netherlands whose contact and order details were exposed through a hacked service provider; payment card data was not affected.
Fix
Treat Lidl-themed messages with caution and verify through official channels. Organizations should assess vendors' security, limit the customer data third parties hold, and require breach-notification and security commitments in supplier contracts.

Glendale College breach exposes data on 793,000 students and applicants

Glendale Community College has had data on roughly 793,000 people exposed after the extortion group ShinyHunters stole files from its student information systems. Have I Been Pwned indexed 793,925 accounts, and the attackers claim to have taken more than 62GB across roughly 304,000 files, including student records with personal identifiers, financial aid exports, immunization logs, admission checklists, and transcripts dating back to 2020. The theft came from the college's PeopleSoft Campus Solutions environment, tying it to the wider ShinyHunters campaign against Oracle PeopleSoft that has hit numerous universities and companies. The breadth of academic and personal data raises the risk of identity theft and targeted phishing against students, applicants, and staff.

Check
People connected to Glendale Community College as students, applicants, or staff should watch for a breach notice, check Have I Been Pwned, monitor financial accounts, and be alert to college-themed phishing.
Affected
Around 793,000 Glendale Community College students, applicants, and staff whose personal, academic, financial aid, and health-related records were exposed; the depth of data supports identity theft and convincing targeted phishing.
Fix
Affected people should consider a credit freeze and monitor accounts. Organizations using Oracle PeopleSoft should apply its mitigations, review access logs, and enforce phishing-resistant MFA against this ongoing campaign.

AssuranceAmerica breach exposes driver's license data of 6.9 million people

US auto insurer AssuranceAmerica has confirmed a breach affecting nearly 6.9 million people, the largest known exposure of Americans' driver's license data this year. The company detected the intrusion on March 17 after attackers compromised a single employee's credentials the day before and copied data files, but a lengthy review of the files was not finished until June 15, delaying notifications until now. The stolen data includes names, contact details, driver's license numbers, auto insurance policy and claims information, and, for some people, Social Security numbers. AssuranceAmerica has not detailed how the employee's credentials were taken, though such incidents are often tied to phishing or credential-stealing malware.

Check
People insured by AssuranceAmerica should watch for a breach notification, monitor bank and credit accounts and credit reports for fraud, and be wary of messages referencing their policy or claims.
Affected
Roughly 6.9 million AssuranceAmerica customers whose driver's license numbers, contact details, and insurance information were exposed, along with Social Security numbers for some; the data enables identity theft and convincing targeted phishing.
Fix
Affected people should consider a credit freeze given exposed license and Social Security numbers, monitor financial accounts, and treat insurance-themed messages cautiously. Organizations should enforce phishing-resistant MFA on employee accounts.

Mount Royal University confirms attackers stole and then deleted its files

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.

Check
Students and staff of Mount Royal University should watch for a notification, take up offered credit monitoring where eligible, and stay alert to phishing referencing the university or their information.
Affected
Mount Royal University students and staff whose academic and possibly personal data sat on the affected drives; the attackers both stole the data and deleted it, complicating recovery and raising extortion pressure.
Fix
Maintain tested, offline backups so deleted data can be restored, segment and monitor file storage, enforce phishing-resistant MFA, and prepare incident-response and communication plans for attacks that both steal and destroy data.

Accenture confirms breach as attacker offers source code and keys for sale

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.

Check
Organizations that work with Accenture or share infrastructure with vendors should watch for supplier notifications, and check how their own source code, keys, and cloud tokens are stored and rotated.
Affected
Accenture and, potentially, its clients; stolen source code, SSH and RSA keys, and Azure tokens could let attackers reach development systems or cloud infrastructure if the credentials are still valid.
Fix
Rotate any exposed keys and tokens, keep secrets out of source code and repositories, enforce short-lived credentials and least privilege for cloud and DevOps access, and monitor development systems for unauthorized use.

Medtronic breach notifications reach 3.8 million people with SSNs and health data exposed

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.

Check
People who have been customers, patients, or partners of Medtronic should watch for a notification letter, take up any offered credit monitoring, and stay alert to phishing that references Medtronic.
Affected
About 3.8 million individuals whose names, contact details, dates of birth, Social Security numbers, and health information were exposed in Medtronic's corporate IT breach; device networks and patient safety were not affected.
Fix
Affected people should enroll in the offered monitoring, consider a credit freeze given the exposed Social Security numbers, and treat medical-themed phishing with caution. Organizations should segment corporate IT from clinical systems.

Case study reveals US county paid $1 million to data-theft extortion group

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.

Check
Review whether you could detect the signs seen here: password-guessed logins, repeated failed logins, and large outbound transfers to burner file-sharing links, and confirm sensitive record stores are segmented and monitored.
Affected
Organizations holding sensitive records, especially smaller government bodies with limited resources; data-theft extortion needs no ransomware, only stolen files and the threat to publish, to force a large payment.
Fix
Enforce multi-factor authentication and alert on failed logins, segment and monitor sensitive record stores, watch for large outbound transfers, and treat any promise to delete stolen data as worthless.

ShinyHunters leaks Moody Bible Institute data on 2.3 million students and donors

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.

Check
People connected to Moody Bible Institute as students, alumni, donors, or staff should watch for a notification, be alert to phishing referencing the school, and check Have I Been Pwned.
Affected
Students, alumni, donors, and supporters of Moody Bible Institute whose contact details and dates of birth were exposed (over 2.3 million emails); the data supports credential stuffing and convincing phishing.
Fix
Affected people should reset any reused passwords, enable multi-factor authentication, and treat school-themed messages with caution. Organizations should secure SaaS and HR platforms, enforce MFA, and harden against social-engineering-driven data theft.
