Windows Kernel Vulnerability Zero Day Found in Duqu Installer.

Vulnérabilité Zero Day du noyau Windows Trouvé

A malware attack Duqu exploits a zero-day vulnerability in the Windows kernel, according to security researchers (like cyber-surveillance Trojan).

The vulnerability has since been reported to Microsoft and Microsoft is currently working on a patch for the kernel vulnerability. Researchers from the Laboratory of Cryptography and System Security (CRYSYS) in Hungary confirmed the existence of the zero-day vulnerability and exploit in a brief note published on their website.

Our laboratory, the Laboratory of Cryptography and System Security (CRYSYS) has continued to analyze the Duqu malware and as a result of our investigation, we identified a dropper file with an MS 0-day kernel exploit inside. We immediately provided the competent organizations with the necessary information so they can take appropriate measures to protect users.

The installation file is a document Microsoft Word (.doc) that exploits a previously unknown kernel vulnerability, which allows code execution.

When the file is opened, the malicious code executes and installs the main Duqu binaries. The table above explains how exploiting in the Word document file eventually leads to the installation of Duqu.

Meanwhile, an expert Microsoft highlights the imminent arrival of Windows 8 (basically it is DTC for the 0-day flaw :93: )
