security question : is it possible in any way for a hacker to deploy a contract to an already existing contract address / in order to overwrite the functions and hijack external calls to this contract?

even in the meantime it is being deployed, it can't "take the place" of the existing code? just to be sure

i saw some exploit that looked like that, where a factory kept testing deploying address until the address matched a lottery win criteria, but i understand that's a different scenario

No, but if there is something at that address and gets selfdestructed yes

I see. Tx

But hacker can't call selfdestruction method without private key of deployed, is it right?

No, depends on how the contract is written

Ok then probably I read that bad the first time who cares

I read you said they needed to implement a function called selfdestruct
