Ok, so how can I retrieve the keys of addresses that share a nonce with a compromised address? I want to check if they follow a specific pattern to identify the ones that interest me in this case.
I can help you if there are addresses that have been compromised before and share the same K value with the target address you want to calculate the private key for. All you need is a compromised address and the same K value between the two addresses. This is the only condition that must be met, a compromised address and the target address must share a K value.
