New Target added

Hey Everyone,

We hope your testing is going well. Here is an update that should make things a bit more interesting!

There have been some recent changes/updates to scope on the Trello program. We highly recommend you take a look at this additional attack surface – which hopefully means more vulnerabilities! Here is what’s new:

  • Trello Mobile App for Android
  • Trello Mobile App for iOS
  • Trelly Desktop Client

As always, please see the program brief for the full details around testing. If you have any questions, please reach out to

Get out there and lay claim to those bugs!
