A revolutionary stealth root kit dubbed "Shadow Walker" that was demonstrated at the BLACK HAT security conference in Vegas this week, can waltz right in to you PC under the noses of even the most sophisticated anti-virus software.

The proof-of-concept, dubbed Shadow Walker, is a modification of Butler's FU rootkit, a kernel-level program capable of hiding processes and elevating process privileges. The rootkit uses DKOM (Direct Kernel Object Manipulation) to fake out the Windows Event Viewer to make forensics virtually impossible and can also hide device drivers

anti-virus scanners must "completely revamp" existing rootkit detection technologies
