How many

  • Name, address, water usage and charges for about 500 people ~500 people

Who is affected

  • Water customers

Cause

While the meter reader was away from home, someone broke a window, entered and stole the meter-reading device

Timeline

  1. Break-in through a window while the meter reader was away
  2. Intrusion stopped
  3. Security NEXT report date; the organization's own announcement date was not confirmed

Response

  • Notified individuals

Apologized to affected customers; will determine water usage in a way that does not affect them

What you should do

  1. Watch for unexpected mail or invoices; your address is hard to change
  2. Check the company's notice to see if you're affected

Lessons for companies

  1. Don't keep ID or bank data: delete after checks or use a KYC provider
  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
