I think that they have to validate the contract before putting it in production and that it has to be approved by maybe 3 programmers?
Because it seems that anybody can create a contract and may be able to modify it if there is no owner? How could there be no owner as someone create this contract?
I don't know how contract programming work.
More information about the hack/bug:
https://www.ethnews.com/unknown-actor-kills-parity-library-contract-freezes-over-500k-etherI would say that it is a bug and not a hack.
Parity has a lot of bug, So many bug in parity. I think every ethereum users should try to avoid the parity wallet. I've seen a lot of the vulneralibity in the code. that seems the parity wallet's credibility already broken. too many hacked case on parity. This why i just try to save my amount into the wallet that has a better code and less bug than parity.
