Is Mayday safe?

Low risk

Mayday lets any webpage with a spoofed trusted origin trigger ticket data to its recommendation API.

Its content script runs on all sites and accepts automation messages when the message body names a whitelisted origin, rather than checking the page's real origin. When accepted, it sends the message's raw ticket payload, such as form-style subject or description fields, to Mayday's custom-event recommendation endpoint.

Where it sends data

Destinations our analysis observed Mayday contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

    Mayday sends data to api.mayday.fr. No other extension we have analysed sends data here.
