  • Engineer — Act: Active hot wallet draining is confirmed on outdated BTCPay Server instances; if you run BTCPay Server for crypto payment processing, update to the latest release immediately and audit wallet transaction history for unauthorized withdrawals.
  • SOC/IR — Learn: Active exploitation is confirmed but the item provides no IOCs, TTPs, or log patterns to hunt with; file for awareness pending a technical follow-up with indicators.
  • Leader — Plan: If your organization accepts cryptocurrency payments via self-hosted BTCPay Server, confirm which version is running and assign ownership of the update; hot wallet draining is a direct financial-loss risk, not just a security posture issue.
