Is there any chance for our private keys getting stolen when we import them in a possible rogue BitcoinABC wallet?
Yes. However, sticking to the official links posted by the OP should be OK, especially since the OP is a bitcointalk staff member. Plus, I don't think Bitmain, who backed the development of this coin, would sacrifice their reputation on releasing a trojan. But you never know in this crazy cryptocoin community.
it actually is a possibility! bitcoinABC is not exactly being released by bitmain. it is a source code on Github with these people (
https://github.com/Bitcoin-ABC/bitcoin-abc/commits/master) who we don't even know are making the changes and commit them to the code.
the code is not even the fork of bitcoin! which means it is impossible for us to go through all of the code, line by line to check where the shenanigans are. if it was simply forked from bitcoin there were a link under the name indicating this and then you could simply compare the two repositories to see only the changes.
see the SegWit2x (btc1) repo, you will understand what i mean. it is simple and fast to check all the changes they have made to the code of bitcoin core.
long story short, i would not trust this client at all unless i can understand the code. which i don't have the time for.
p.s. it doesn't even have to be a trojan to leak your private keys. (just an example:) imagine if the way you make the transactions with their code has a bug in it that produces weak signatures and leaks your private keys when you sign a raw transaction and broadcast it!
