One month ago, I was part of a coordinated attack on blockchain executives. (I am one of the co-founders of https://provide.services). It was shockingly easy for them to take over my accounts, despite being security conscious. They attacked dozens of others around the same time across T-Mobile, AT&T and likely others.

I hope this story and the lessons learned helps you protect your crypto!
