  • Respondents to magazine reader surveys

A third party breached the web server and may have stolen reader-survey data from its database

  4. Disconnected from the internet
  5. Security NEXT report date; the company's own announcement date was not confirmed

Response

  • Blocked the entry point
  • Notified individuals
  • Forensic investigation

Investigated with help from group companies; notifying affected readers in writing where contact details exist; will restore service on a new, hardened environment

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. 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
