    Twitter hhsecwatch Hamish from spikes:
We were very grateful for Vitor's notification. He was quick to respond to our email and confirmed the type of vulnerability he had discovered. Our application was already undergoing a paid pen test, and the issue that Vitor found matches what our pen testers found, which is reaffirming.
@michaeljkranz     7 December, 2017
    Twitter michaeljkranz Michael Kranz from Simons Foundation:
Vitor not only caught the bug, but quickly responded to our request for more information. Our site (Spectrum - was designed and built by an external firm, so I wasn't familiar with every possible problem. However, this vulnerability was pretty significant and we're very grateful for the help, which came completely out of the blue.
