The culprit of this attack is Frederick Brennan aka Hot Wheels.
He was openly talking about doing this very thing to us back in November 2019 via a cyber attack tool he called Tesseract. It involved captha cracking.
He did it.
IIRC Hot Wheels is based in North Hollywood right now (by his own admission).
Someone needs to “send some swat his way” if you know what I mean.
