How many

  • Customers who used the contact form 4 people

Who is affected

  • Customers who used the form

Cause

Unauthorized access exploiting a vulnerability in software used on the site; part of the site was altered

Timeline

  1. Intrusion began
  2. Intrusion stopped
  3. First disclosure

Response

  • Data deleted
  • Patched
  • Notified individuals

Removed the planted malicious files and restored the tampered parts; fixed the vulnerability; contacting affected customers individually

What you should do

  1. Don't open links in emails from this company. The apology email itself may be fake
  2. Treat refund or apology calls and texts as scams. Call back only on the number from the official site
  3. Check the company's notice to see if you're affected

Lessons for companies

  1. Patch internet-facing servers, VPNs and admin panels first. Exploits follow disclosure within days
  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
