Isn't it strange this exchange didn't have a limit in place so to safe guard against them withdrawing the entire amount from the account before the original account knew and could of stopped the second withdraw from happening? Atleast the hacker wouldn't have been able to drain the account completely of their funds.
It might be an inside job, let's see if filing the lawsuit will result in anything. I don't want to give the victims some bad news but base on the Korean movie that I saw (Master), they have a problem with their authorities. politicians, prosecutors and most of the high ranking officials, are connected to this kind of scam. they receive some payment from the suspect. they have done it clean so that no one can expect them to be controlled by the suspect.
This is the case with the movie, when something like this is happening right now the case is not far from reality, right?
So how will they get back their funds? when everything is already planned including the lawsuit.
And of course we all know that movies and reality are one and the same. Specially in Korea, where the meaning of drama must lie hidden in the name somewhere...
Politic fiction dramas aside, online wallet liability should indeed be a thing. But it is more complex than that, user side security is also a big issue. Not saying online wallet operators often are negligent but a proper investigation is needed.
In reality its usually both, as the whole idea of users using insecure practices and software, trust "online" because they feel incapable of securing funds by themselves. In that case you are using a service so a third party has your money safe, and such service would be breaking their part of the contract if they fail to do so (that is why you were paying them in the first place).
Exchange is but one type of typical online wallet operator (there are a few exchanges where you can use your own wallet instead). This is pretty much a type of bank (full reserve bank) and could perhaps receive the same (or better) type of regulations.
This mess only exists because of the need to exchange fiat to crypto, else people could all just keep things in their own wallet unless they don't want to.
