Blocked all access to the related servers; closed the Charm main store and stopped order taking and shipping; reported to the PPC and JIPDEC; individual notices planned; password-change instructions to follow. Helpline 0120-89-4828 (8:00-17:00, every day)

What you should do

  1. Change this password and every account that reused it now. Weak passwords crack even when hashed or encrypted. Switch to a passkey where offered
  2. Don't open links in emails from this company. The apology email itself may be fake
  3. Treat refund or apology calls and texts as scams. Call back only on the number from the official site
  4. Watch for unexpected mail or invoices; your address is hard to change
  5. Check the company's notice to see if you're affected

Lessons for companies

  1. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  2. Run red teaming and AI-assisted hardening, and publish how much you invest
