Additional Microsoft Defender tools and services that provide security across various platforms and environments
James,
Form what I found you've managed to dredge up something related to the Microsoft Anti-Virus Reward Program from November 5, 2003 regarding those behind the 2003 MSBLAST.A Virus.
Here's the original Press release and a quote that mentions this specific malware as the first reward offered for that program.
"As part of the Reward Program, Microsoft announced the first reward in the amount of a quarter-million dollars (U.S.) for information leading to the arrest and conviction of those responsible for unleashing the MSBlast.A worm."

So, whatever you had found was either dredging up ancient history or more likely was just another article that referenced this initial press release as well.
