Easy to accuse North Korean government since their people couldn't read these news. I bet they'd react not true if they ever got access to the news. They've been isolated since the world isolate them as well but they do have friends like Russia and China.
Everyting is still an accusation though, even in the past they were also accused but nothing happened. So if even an exchange wants to steal the money from the users, they can always say they are hacked and accuse the Lazarus and they are off the hook of the responsibilities but blame North Korean government.
The thing that is feared should not happen, namely that many people make North Korea an accusation for a case that is being covered up... I am not accusing the Bybit team of committing fraud and then using North Korea's status as their shield, but this could be a negative thing in the future... the team and staff can always easily manipulate their money because in general centralized exchanges always keep their financial conditions secret in detail...
As long as it is still an accusation, there is indeed a possibility that North Korea is the main perpetrator, but it is also possible that North Korea is only used as a victim of the accusation. The FBI does have good performance, but we know that this US product also has a conflict with North Korea, so we can see news that is distorted at any time regarding the feud between these countries.
