I also noticed the BNB hack today because i wanted to recompound one of my investments but i could not do that because the whole BNB chain was paused for quite a while after the hack has happened, so that definitely was a pretty big incident in my opinion. As of now everything seems to be working again. As far as i know the hacker got away with BNBat least worth 100 Million $. Also it seems like hacks on the BNB chain seem to happen at least once a year which is a little much for my personal liking. Therefore i am pretty surprised that the price of BNB only went down a little after that news became public.
