First, do not panic
A fake invoice QR code arrives inside a bill that looks like it came from a supplier, utility, or service you use. The invoice may carry your name and a plausible amount, but the QR code routes payment to someone else.
If you already scanned, the next few minutes matter more than the scan itself. What you do now can limit the damage, and most of the steps below take only a few minutes each.
Contain it right now
1. Stop the payment if it has not cleared, and contact your bank at once about recalling it.
2. Do not enter further credentials on any page the QR code opened.
3. If you entered account details, change the password from a clean session and alert your finance team.
4. Keep the invoice and the payment confirmation for the bank and any report.
What to check next
- Reconcile recent payments to the same supplier and look for other invoices with altered details.
- Tell the supplier that its name is being used, so it can warn other customers.
- Report the invoice to your bank fraud team and to local police if money was sent.
- Record the new payment instructions so the same change is not accepted again without verification.
Reporting helps the next person
Reporting is not just paperwork. It helps the impersonated organisation warn other customers, helps platforms remove the fake page, and helps investigators connect one scam to others. Report promptly, and include the time, the place or message, and what you entered. You do not need to feel embarrassed about reporting. These scams are built to fool busy people, and a fast report protects everyone who comes after you.
Putting this into practice
Work through the steps in order: contain, check, then report. Start with the highest-risk exposure first. If money is involved, the bank comes before everything else. If credentials are involved, change the password from a clean session and review active sessions and linked devices. Write down what happened while it is fresh, including the page address, the payee name, and the time, because those details make reports and disputes easier.
Common mistakes to avoid
One mistake is trying to fix things by scanning the code again or following more links from the fake page. Another is assuming nothing happened because nothing looks wrong yet. A third is delaying the report out of embarrassment, which gives the attacker more time to use what was taken. Act on the exposure you had, not on whether you can see damage yet.
Quick checklist
- Close the fake page and do not follow further links from it.
- Change any exposed password from a clean session.
- Review active sessions, linked devices, and recent activity.
- Contact your bank at once if money or card details were involved.
- Report the code to the impersonated organisation and the platform.
- Keep a written record of what happened and when.
