PaySystem.tech Data Breach

What happened

In mid-2022, data alleged to have been sourced from the Russian payment provider PaySystem.tech appeared in hacking circles where it was made publicly available for download. Consisting of 16M rows with 1.4M unique email addresses, the data also included purchases and full credit card numbers and expiry dates. The data could not be independently attributed back to PaySystem.tech and the breach has been flagged as "unverified".
