I have been following his thread on Twitter and it’s scary what he discovered. Apparently there were some people whose cold storage and hardware wallet funds were also drained. And he still can’t find the flaw.
Many ETH ICO tokens which were never moved were also stolen and these were OG unlike new retail users. Only thing I can think of is the last pass hack and they kept their seed hosted there. Since the hacks started around that time.
This is very terrible, if it's like this there is no safe place to store the assets that we have.
When storing on a centralized exchange, sometimes there are also feelings of anxiety because large exchanges cannot guarantee that our assets are safe either.
