What you should do
- Scammers who know your account number pose as refund staff. No bank or company asks for your PIN
- Don't open links in emails from this company. The apology email itself may be fake
- Treat refund or apology calls and texts as scams. Call back only on the number from the official site
- Watch for unexpected mail or invoices; your address is hard to change
- Check the company's notice to see if you're affected
Lessons for companies
- Passkeys or MFA for every account; monitor leaked credentials and rotate API keys
- Don't keep ID or bank data: delete after checks or use a KYC provider
- Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
- Run red teaming and AI-assisted hardening, and publish how much you invest
