Reporting a Malicious QR Code Properly
A report that says 'there was a bad QR code' cannot be acted on. A useful report answers six questions: what the code contained, where it was, when it was found, what it did, what was done about it, and what evidence survives. This builder structures those answers so a security team, a venue owner, or a platform can act without coming back for the missing detail.
What to preserve before you report
Photograph the code in place before removing it — the photo proves the context and shows whether it was a sticker over a legitimate code. Save the decoded payload exactly as scanned, and screenshot the page it opened if it is safe to do so. Do not rescan the code on a personal device to gather more evidence, and do not enter any credentials on the page.
Who should receive the report
- The venue or business owner, if the code was on their premises or packaging.
- Your security team or IT helpdesk, if the code targeted staff or customers.
- The platform hosting the destination, if it is a phishing page.
- The domain registrar, if the domain is impersonating a brand.
If anyone entered credentials or payment details after scanning, treat that as a separate incident: change the affected password, review the account, and note it in the actions-taken section.
