About This Record
According to CyberInsider’s June 11, 2026 report, the company said operations were unaffected but did not confirm a breach. The June 6 catalog date is the intrusion date claimed by the actor, not an independently verified date.
The report says screenshots and samples supplied by the actor appeared to show approximately 1.1 million account entries alongside contact and user databases. leaksear.ch separately reports 14,600 person-level contact, user and opportunity records in its narrower normalized index, which excludes standalone business-account rows and entries without an email deduplication key.
The sources report email addresses, names, phone numbers, physical addresses, countries, usernames, IP addresses, job titles, employer information and CRM context. They do not establish that all fields occur together in every record. The 1.1 million and 14,600 figures describe different scopes; neither is a confirmed unique affected-person count or a count imported into Leakdata.
Verification and editorial method
LeakData compares the incident name, date, affected-record count, and exposed data types with accessible sources. Unverified fields are not presented as facts, and records are updated when new evidence becomes available.
