Authenticity check — no account, no upload
Does this really come from us?
Two out of three cyber reports in Switzerland are not hacking attacks — they are fraud. The most common trick is the most boring one: an invoice that looks genuine. So we keep a public registry of everything we issue.
Everything from us is in the registry. If it is not in there, it is not from us.
Drag a file here
or click to choose one
The file stays on your device. The calculation happens in your browser; nothing is uploaded.
Try it
Download this file, save it somewhere, then drag it into the box above — that is what a match looks like:software-abos-a.png. For the counter-test, use any file of your own: we do not know it, and that is exactly what we will tell you.
How this works
Every file has a fingerprint — a long number derived from its content. Change a single character and the fingerprint changes completely. Your browser computes it and compares it against our registry. We never see the file itself.
Whoever can produce the fingerprint already has the file. That is why we may show details on a match without giving anything away. The file is the key.
What this cannot do
An invoice from a sender who never registered anything cannot be checked here. This registry answers exactly one question —is this from AnalytikData — and answers it completely. It currently holds 208 entries.
