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.
Data from a breach of American Tower, one of the largest wireless communications infrastructure companies, has been indexed by Have I Been Pwned, which added 216,601 affected accounts. The extortion group ShinyHunters is linked to the incident, consistent with its sweeping 2026 campaign that has used social engineering against staff to reach corporate systems and exfiltrate data at major enterprises. American Tower operates critical telecom infrastructure, making any exposure of employee or partner data a concern for follow-on phishing and targeted attacks. Exposed contact details are commonly reused for convincing phishing against affected individuals and the organization.
Have I Been Pwned has added 139,903 accounts from a breach of fashion brand Ralph Lauren, which the extortion group ShinyHunters claimed as part of its sweeping 2026 campaign against retail and luxury names. ShinyHunters says it took around 220 GB of data, including customer personal information, purchase histories, and financial transaction details, along with unreleased product and strategy plans. The group typically breaks in not through a brand's core systems but via connected platforms like Salesforce or customer-service tools. Exposed purchase and contact data is prime material for convincing phishing and fraud aimed at the retailer's customers.
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.
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.
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.
Have I Been Pwned has added BCD Travel - one of the world's largest corporate travel-management companies - to its breach corpus with 396,313 unique email addresses. BCD Travel arranges business travel for large enterprises and government clients worldwide, so the exposed dataset likely skews toward corporate and frequent-traveler accounts. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Affected travelers should anticipate travel-themed phishing - itinerary updates, booking confirmations, loyalty-program lures - and should rotate any reused passwords and enable MFA.
Have I Been Pwned has added US dental-benefits provider DentaQuest to its breach corpus with 2,553,599 unique email addresses. DentaQuest is one of the largest dental and vision benefits administrators in the United States, serving Medicaid, Medicare, and commercial members. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Healthcare and insurance data carries elevated risk: affected members should anticipate benefits-themed phishing, claim-status lures, and identity-theft attempts, and should rotate any reused passwords. It is among the larger US healthcare-adjacent breaches surfacing recently.
Have I Been Pwned has added the US automotive marketplace Edmunds to its breach corpus with 177,860 unique email addresses. Edmunds is a widely used car-research and shopping platform offering pricing, reviews, and dealer listings. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Affected users should anticipate car-buying-themed phishing such as financing offers, dealer-contact lures, or vehicle-quote follow-ups, and should rotate any reused passwords. The addition continues a steady run of mid-size US consumer-platform breaches surfacing in HIBP.
HIBP has confirmed 4.9 million unique accounts (4,851,517 email addresses) were affected by the Charter Communications breach disclosed earlier this week. The ShinyHunters extortion gang initially claimed 42 million records exfiltrated from Charter's Salesforce instance via voice-phishing of a Microsoft Entra account on April 1; the unique-account count is lower because individuals appeared on multiple records (customer + business + plan-info). Charter publicly denies that CPNI (Customer Proprietary Network Information) or sensitive personal data was taken. The HIBP entry refines the scope to a defender-actionable figure and lets customers and IR teams check exposure across their workforce.
