  Polymorphic Shellcodes vs. Application IDS's
------------------------------------------------------------------------

SUMMARY

An article on Polymorphic Shellcodes (shellcodes that utilize methods to
hide the fact they are of binary form, and contain malicious code), and
how IDSs can possibly detect them has been published by NGSec.

DETAILS

A document written by NGSec focuses on how IDS, under certain
circumstances, can detect Polymorphic shellcodes. The document then goes
through the three main parts of a polymorphic shellcode and analyzes IDSs'
common problems to detect them.

ADDITIONAL INFORMATION

The document (white paper) can be downloaded from:
