In October 2005, Windows expert Mark Russinovich broke the news about a truly underhanded copy-protection technology that had gone horribly wrong. Certain Sony Music CDs came with a program that silently loaded itself onto your PC when you inserted the disc into a CD-ROM drive. Extended Copy Protection (or XCP, as it was called) stymied attempts to rip the disc by injecting a rootkit into Windows . The concept of the rootkit isn't a new one, and dates back to the days of Unix. An intruder could use a kit of common Unix tools, recompiled to allow an intruder to have administrative or root access without leaving traces behind. Rootkits, as we've come to know them today, are programs designed to conceal themselves from both the operating system and the user The link for this article located at InformationWeek is no longer available. . Rootkit development has evolved alongside tech advancements, becoming complex systems that infiltrate OS deeply. This article reviews 6 effective rootkit detection tools.

After scanning two million images from eBay without finding any hidden messages, we extended the scope of our analysis. A detailed description of the detection framework can be found in Detecting Steganographic Content on the Internet. This page provides details about the analysis of one million images from the Internet Archive's USENET archive. Processing the one million images with stegdetect results in about 20,000 suspicious images. We launched a dictionary attack on the JSteg and JPHide positive images. The dictionary has a size of 1,800,000 words and phrases. The disconcert cluster used to distribute the dictionary attack has a peak performance of roughly 87 GFLOPS. . .

The presentation I gave in Washington, D.C., at Black Hat Federal Conference in January 2006. It's about new generation of stealth malware, so called Stealth by Design (SbD) malware, which doesn't use any of the classic rootkit technology tricks, but still offers full stealth! The presentation also focuses on limitations of the current anti-rootkit technology and why it’s not useful in fighting this new kind of SbD malware. Consequently, alternative method for compromise detection is advocated in this presentation, Explicit Compromise Detection (ECD), as well as the challenges which Independent Software Vendors encounter when trying to implement ECD for Windows systems. .

As cyber threats evolve, Stealth by Design malware poses significant detection challenges for security teams, necessitating advanced behavior-based approaches..
