The WPS vulnerability was independently discovered by Craig Heffner of Tactical Network Solutions but Stefan was the first guy who reported the vulnerability and released the information about it to US-CERT.

After the Tactical Network Solutions released reaver, he also released his PoC Brute Force Tool which is faster than reaver but but will not work with all Wi-Fi adapters.
