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. Expect targeted phishing posing as HR or interview contacts
  4. Check the company's notice to see if you're affected

Lessons for companies

  1. Two-person review and pre-release tests for sharing and cache changes; monitor cloud config (CSPM)
  2. Report to the PPC: preliminary in 3–5 days, final in 30 (60 if malicious)
  3. Run red teaming and AI-assisted hardening, and publish how much you invest
