Publisher review:IIS-ipblocker helps you to stop automated brute force attacks against your IIS web server. Reason for this script: To help stop automated brute force attacks and vulnerability scans. Are you tired of seeing: www.yourdomain.com......cmd.exe etc... in your web server logs?
Since IIS doesn't normally use .htaccess there is no easy way to automate the process of banning IP addresses via IIS.
This script uses a custom 404 page that logs the IP address and amount of times it has loaded the 404_error.pl .
If someone loads the 404 page 3 times in succession their IP address is logged to the banned_ip_list.log file. Every 60 seconds build_deny_list.pl opens the banned_ip_list.log file and gets the IP address to block.
It then generates some C# code, adds that banned IP to the C sharp code, compiles the C code into an executable binary. This C sharp program is actually what adds the IP to the IIS deny list. After the build_deny_list.pl generates and executes the binary, it deletes the original source and executable file. Requirements: · Microsoft.NET version 1.1.4322+ · Active State Perl
