About This Breach

Attackers used compromised credentials from a third-party vendor to breach the corporate network, deploying custom RAM-scraping malware across thousands of Windows-based point-of-sale (POS) self-checkout registers. The undetected intrusion compromised approximately 56 million payment card numbers and 53 million unique customer email addresses, resulting in over $160 million in legal settlements and security remediation costs.
