I don't know why I always have the feeling that most of these hacks are done by the developers of these wallets. I can be wrong but I think there is always an insider in all these as it is easier for the developers to find any loopholes than an outsider.
Thinking of it like a back job from the developers themselves, right? That gut feel could be right but it will remain as a gut feel as we can't prove that.
If you love your funds, I will advise you stay away from that wallet because this is a very bad signal. One of the ways to avoid regrets is in this digital space is to be sensitive to red flags such as we have seen in atomic wallet.
There have been bad news about that wallet and that's why it's best to avoid it while you can. There are people that are hard hearded that despite knowing the news about them, they don't bother and just continued using it.
