signature malleability in 60 seconds in the EC DSA algorithm you generate R and S values the R value is the x coordinate of a randomly generated public key that is used in the signing process the s-value corresponds to the R value and is related by this equation youamp;#39;ll notice however that in an elliptic curve there are two points that have the same x value there is a second s value that satisfies this equation for the same message from the same signer in this contract an attacker can observe the owneramp;#39;s original message with the VR and S signature and manipulate these values to provide a second valid signature and double spend from the smart contract
