Why MS10-046 mentions my name

Some people have asked me why Microsoft credits me in MS10-046 (a.k.a. the patch for the lnk bug). In version 1.0 of the original advisory they only mentioned .LNK files as an attack vector. When playing around with the bug and the published exploit code, I discovered the vulnerability could also be exploited with .PIF files (MS-DOS shortcuts). This was the case even after applying the workaround (disabling the display of icons on lnk files). So I contacted the MSRC, they updated the workaround and were kind enough to credit me for the additional attack vector.
