Have I Been Pwned has added 368,418 accounts from a breach of JCPenney, after the extortion group ShinyHunters claimed in mid-June it stole data from the retailer and several sister brands under Catalyst Brands and Authentic Brands Group. ShinyHunters says the haul includes highly sensitive employee and customer data: Social Security numbers, dates of birth, W-2 tax forms, payroll records, and scans of government-issued IDs. Unlike passwords, these identifiers cannot simply be reset, raising long-term identity-theft and tax-fraud risk. JCPenney has not confirmed the full scope, and the group has not published samples, but the data types make this a serious exposure.
Cybernews researchers found an unprotected Elasticsearch database holding 24 billion records and over 8 terabytes of data, most of it infostealer logs: stolen usernames, passwords, and the services they unlock. The collection also pulls from Telegram channels and older breach dumps. Oddly, it included thousands of records tracking CVE vulnerabilities, breach news articles, and social-media posts about cyber incidents, with content as recent as 2026, suggesting the owner is actively curating and refreshing the stash with new leaks. The researchers could not determine how many records are duplicates, how old the data is, or who owns it.
Nintendo of America has confirmed that attackers stole internal employee data through TinyPulse, a third-party employee-survey service run by WebMD Health Services, after a threat actor calling itself SHADOWBYT3$ posted the haul and demanded a $2 million ransom. Nintendo says its own systems were not breached, no customer or financial data was touched, and the exposure is limited to internal survey content for a small subset of employees, mostly several years old. The attacker, however, claims to hold more, including bank statements and tax forms. The incident is a textbook third-party vendor breach affecting a major brand.
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.
Have I Been Pwned has added 248,235 accounts from the March breach of CFGI, a US accounting and financial-advisory firm that works closely with corporate finance teams at mid-market and Fortune 500 companies. The extortion group ShinyHunters claimed the intrusion, posting hundreds of thousands of records including names, emails, phone numbers, and home addresses, along with internal corporate documents and identity-system metadata. Because CFGI sits inside its clients' finance functions, the stolen contact and relationship data is unusually useful for convincing business email compromise and client-impersonation scams aimed at authorizing fraudulent payments.
iRhythm, the US digital-health company behind the Zio wearable heart monitor, has told regulators that attackers stole patient data in a breach it considers material. In an SEC filing, the company said it detected unauthorized activity on June 8 in third-party-hosted business applications, accessed through a social-engineering attack, and received an extortion demand the next day from a threat actor claiming to hold proprietary data, protected health information, and other personal data. iRhythm says its clinical systems, medical devices, patient safety, and operations were not affected, with no payment-card or financial data involved. No ransomware group has publicly claimed the attack, and the number of affected people is not yet known.
Breach-tracking service Have I Been Pwned has added a fresh batch of stealer logs covering 56,278,397 accounts, harvested by infostealer malware from infected computers. Unlike a single company breach, stealer logs are credentials and session data scraped directly from victims' devices, often capturing the exact website-and-password pairs a person types, plus browser cookies that can let attackers skip login entirely. Because the data comes from malware on individual machines, exposure cuts across countless unrelated services. The scale is a reminder that infostealer infections, frequently spread through cracked software, malicious ads, and fake downloads, remain one of the biggest sources of credential theft.
Breach-tracking service Have I Been Pwned has confirmed that 305,216 accounts were exposed in the March attack on Berkadia, a large US commercial real estate finance firm that handles mortgage banking and investment sales. The extortion group ShinyHunters claimed the intrusion, saying it stole millions of Salesforce records containing personal and internal corporate data, around 27GB compressed, and threatened to leak them after the company did not meet its deadline. The breach is part of a broad ShinyHunters campaign this year against companies' Salesforce environments, typically entered by socially engineering employees or help desks rather than exploiting a software flaw.
Have I Been Pwned has confirmed 137,123 accounts exposed in a breach of Infinite Campus, a widely used K-12 student information system in the US. The extortion group ShinyHunters claimed the attack back in March, posting that it had stolen personal data and internal corporate information. Because student information systems hold sensitive records on minors and their families, exposed data raises the risk of identity theft and highly targeted phishing aimed at parents, students, and school staff. The incident fits the same ShinyHunters data-theft pattern seen across the education sector this year, including the much larger Canvas breach.
The Iran-linked group Handala claims it breached California Water Service (Cal Water), one of the largest US investor-owned water utilities, and published a 5GB sample to prove it. Analysts say the attackers reached a customer billing database holding personal data (names, addresses, account and payment details) and an internal GPS-correction server, leaking administrative credentials in the process. Handala framed the attack as retaliation for US actions against Iran and boasted it could disrupt water supply, but researchers stress the evidence does not support that claim, neither system controls water treatment, and the group is known to exaggerate. Cal Water has not yet publicly confirmed the incident.
