If the signer's private key is kept secret from attackers, no known forgery attacks work against a properly secured implementation of ECDSA. X9.142 specifies a digital signature algorithm, the ECDSA.

The research team discovered that an ECDSA key was stored unencrypted in the file of ClipUp, a program that converts Windows 8 store licenses, genuine tickets, and product keys into digital licenses.
