Relevant signatures for those who wants to give it a go. There's nothing similar about the signature, which is common for reuse r values. Johoe posted it here[1] years back. And for this, AFAICT, isn't vulnerable with the reuse r values. Guess you're just trying to steal some coins?

Yeah, these signatures aren't reusing R at all, or it would be glaringly obvious.

It's even stated in the thread that the owner of the compromised addresses ( keys) should sign for this address, because this one isn't compromised.

@OP what are you doing? Where did you get this address from?

But I dont know how find msghash1 mshhash2 what is it?in ruby script,I already entered sig1 hex sig2 hex,it is r1 r2
if a signature is in DER format, you can decode it like this

Code:
30450221009caa9cfc1d305536b1144e1e90b01212f1d68101b9f6a5738bb8a3bbc48a587702203c225b31571ae1ef20d544be97566c0e09d44adc4199ef684e1313a31cf11ee701
Code:
30 <length> 02 <r length > <rhex> 02 <s length> <s hex>
so for the above sig,
