SHELLCODE: Metasploit JavaScript Obfuscation
This signature detects the use of the Javascript String's Replace function as a method of creating obfuscated Javascript to avoid content inspection/filtering systems. Such scripts are commonly used by Metasploit to avoid IPS detection, but can also be used by ad-ware for similar reasons.
