ZDnet has this article today of an ebay auction for information on a Microsoft Excel vulnerability that the auction-seller had notified Microsoft of.
An online auction of a “brand new vulnerability” in Microsoft Excel had reached about $60 when eBay pulled the item late Thursday.
A seller using the name “fearwall” started the auction Wednesday evening at 1 cent. It was up to $56 on Thursday afternoon with 21 bids placed, and eBay quashed the auction soon after that.
