Trust wallets are vulnerable to hacking because the key uses the pharse method, which has previously been hacked by guessing the phrases until they are correct. This should be a consideration for looking for alternative pad keys, for myself, for wallet security, it is more convenient to use the private key (myetherwallet)method.
That is not personally made neither, there are some bots that is designed to crack it, and phrases means that you could literally try all the worlds as a combination and yes that requires a powerful computer but you would be going insane if you saw some of the botnets that these people have.
I have seen as high as 10 thousand computers (not all used by hackers, some just hacked to be part of botnets) used for one purpose. That type of power is insane and could crack any type of password or phrase. It's always better to have 2fa type of protection because that would be ever changing, and wouldn't give the botnets time to crack into it, will be a brand new one each 5 seconds or so.
