2026 Hallmark Cards / Hallmark+ — ShinyHunters Salesforce leak (multi-million records; Apr)
Data compromised
Customer contact fields, support/ticket context per analyses
Technical writeup
April 2026 trade coverage tied Hallmark Cards and Hallmark Plus to ShinyHunters activity involving a large Salesforce-oriented dataset, with public estimates ranging from roughly 1.7–2 million unique emails in Have I Been Pwned–style summaries up to higher row counts in forum marketing. Exposed fields in analyses included names, emails, phones, addresses, and customer-service context. Extortion and post-deadline leak narratives mirrored other ShinyHunters retail campaigns; independent reconciliation of row counts versus unique individuals may differ.
