Signature - rsz - private key - ECDSA - calc - public key

[WCX-SCAM]

Hello! I have 2 signatures offline with the same private key and I would like to know if my private key is at risk.
The attacker knows the difference between k-d of the 2 signatures

signature 1

k-d = 0x99efbe8ab7519fb46bf1f6dd4fedf30a7677ccec3c241e72fb2abff5313c779b

r   0x74fd78ede0ab694817af40f20d560ff9f6c87aa251e5c55970fef4e178d09caa

(s1*r2-s2*r1) %N = 0

these signatures have the same root so you can't break them.

Q: I have 2 signatures offline with the same private key and I would like to know if my private key is at risk

A: Yes

They were generated without internet access, the device was destroyed and the private key is encrypted

I don't think it's risky. RIGHT?
