Yes its an old trick that still works till date ,the most dangerous ones now is backlogger malware and phishings ,you have to thread carefully in crypto space or you will lose all you've worked for
There are so many tactics these scammers use from time to time, and I sometimes suspect these hackers to be among some of these projects we are participating in because I wonder how a scammer can easily spot me out to have wanted to hack into my crypto mail, to the extent of trying to hack my local exchange account.
We really need to be very care in this crypto space and make sure all our coins are always in a wallet and probably get a hard ware, for my keys, I have decided not to keep them online, what I did was to print all my keys out in a paper, keep one copy of it in my bank safe and another copy of it in my personal safe, lets see the hacker that will go to my back or come to my house to break my safe.
