News is everywhere. Sony's latest CD installs a rootkit which hides itself from Windows OS. A few days ago Mark Russinovich wrote about his ingenious investigation and reveal of the rootkit in his blog. Apparently, rootkit was hiding any files that started with $Sys$. Fire caught up and in two days time Sony felt to pressure and responded with the "somewhat sloppy" fix.
SysInternals has a free utility called RootkitRevealer that I would suggest everyone to use as RootKits are much more dangerous that Viruses and Worms. You may never know you have it in your system to begin with! Congrats Mark, you are my hero :)
