How many

  • Customers whose information, including credit card data, may have leaked 9 people
  • Of these, customers who completed payment 4 people
  • Of these, customers who left the order without completing payment 5 people

Who is affected

  • Customers who entered information on the order confirmation page

Cause

A vulnerability in part of the system used by the site was exploited, administrator privileges were obtained without authorization, and a malicious program may have been running. Information entered on the order confirmation page while it ran is affected

Timeline

  1. Malicious program started running
  2. Malicious program stopped running
  3. Service suspended
  4. First disclosure
  5. Update: cause announced, with 9 affected customers whose data, including card data, may have leaked

Response

  • Service stopped
  • Forensic investigation

Temporarily closed the site and continues an investigation by an outside specialist firm. Reported to the card companies, the payment processor and the Personal Information Protection Commission. Asked customers to check their card statements

What you should do

  1. Call your card issuer, reissue the card, check statements daily and turn on alerts
  2. Don't open links in emails from this company. The apology email itself may be fake
  3. Treat refund or apology calls and texts as scams. Call back only on the number from the official site
  4. Watch for unexpected mail or invoices; your address is hard to change
  5. 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. Don't keep ID or bank data: delete after checks or use a KYC provider
  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
