There are high-level attacks that target large platforms and well-known services, causing the loss of millions, and then come low-level attacks carried out by these scammers who are ready to steal any amount from users, even if it is $1.
Yes, there is no one that can not be targeted. The low level hacks are targeting individuals. But as you call them low leverage, soke of the hackers are every rich people and they are in other type of scam also just for money to be main illegal, they do not care.
I tried to search if there are people who already fell for that scam, I couldn't find any reports. So I guess people have already matured now, those who are using exchanges are likely not gonna fall for this obvious scam. Especially since Binance had made a timely warning as well.
Only a fool will fall for it because Binance has been saying nobody will lose money. People can not be very wise like that, they will remain being people. Some will be wise and some will not be wise.
