Microsoft has become rather tight lipped in its security bulletins. Some time ago the company would provide readers with data regarding the soon-to-be-patched flaws. However, now the Redmond company seems to be under a thick cloud of secrecy and would rather keep its publicly disclosed info to a minimum.
It look be a way to keep at least some hackers from taking advantage of a certain exploit, but it’s hard to believe that such measures are actually effective.
Hopefully, the company will talk some more after the patch is released.
