Very sad to hear that and this is definitely something happening in the cryptocurrency space including the Avalanche coin network.
It seems that this is indeed bad news from Vee Finance and it is time for Avalanche to improve themselves in their security system. This always my analysis .
I'm also sure that Vee Finance has a strong team who are experts in hacking and of course Avalanche also has a strong community but if there is an exploit like this then this is already bad news for Avalanche
