2 most common vulnerabilities are repetitions of K for the same private key and weak K
We have only 2 signed messages and their signature r does not match, only the weak K remains.
I checked 02/03838db77b981db321faf527a830461cfda01aed50d85c345a7b0a8f4e5e4fd3fc in the 80-bit range it is not there.
sha256 from the message also does not reveal r, as well as double hashing.
The rabbit hole is too deep. I'm tired))
