What you should do

  1. Treat refund or apology calls and texts as scams. Call back only on the number from the official site
  2. Watch for unexpected mail or invoices; your address is hard to change
  3. Check the company's notice to see if you're affected

Lessons for companies

  1. Put security requirements, audit rights and reporting deadlines in vendor contracts
  2. Offline backups with restore drills; segment the network
  3. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  4. Run red teaming and AI-assisted hardening, and publish how much you invest
