Nikon's signature mechanism broken, vendor ignores the problem

According to this article, russian company ElcomSoft (well-known for the lawsuit in which Adobe attempted to attack the company for finding weaknesses in Adobe's DRM) managed to extract the private key from DSLR cameras, produced by Nikon. This allowed the designers to create fake pictures and make them look as real ones by digitally signing these pictures.

Nikon supposedly doesn't react on the problem, ignoring it. Ostrich position of Nikon is bad cause, as much as with ostrich, while protecting the head it leaves the back (and everything below) opened to attacks.
