Software

Lock NT Domain Accounts

A Denial-of-Service (DoS) attack could be launch aginst NT Domain accounts with policy to lock out account forever after certain number of attempts. See a simple proof-of-concept script lockNT.zip and a small article.

Mail Forgery Test

Mail_Forgery.zip is a simple SMTP client written in PERL to perform Mail Forgery (Spoofing) Test. See more about Mail Forgery.

Dictionary Attack against basic authentication over SSL (HTTPS)

Simple PERL script ssl_dic.pl to perform a dictionary attack against basic HTTP authentication over SSL (HTTPS).

Assess Windows NT/2000 Passwords

Assess_PASSWORDS.zip is simple batch script used to assess and report strength of user passwords without revealing username-password combinations. It utilizes John the Ripper tool on Win 32 to perform password cracking and GNU SED for analysis and reporting.  See README.txt for details.

C-style Include for HTML

A PERL script prep.pl to perform C-style include into a HTML file using directive <!-- #include "include_file" --> for HTML preprocessing. Allows to separate a content from page feel and look. Mini version of Website Meta Language (WML).

Measure host's Availability

Unlike the usual UNIX uptime command the PERL script uptime.pl measures actual host availability even after reboot. It keeps up/down time information in the /etc/uptime.db file.
The script uptime_report.pl will generate an HTML availability report.

Development Projects

Network Profiler

A PERL script to import information collected by tools such as NMAP, NBTSTAT, SNMPWAL, etc. to a MS Access database for better network configuration analysis.

Get the latest non-stable version: profiler-0.2.tgz

Simple Firewall

A set of IPTABLES management scripts on a RedHat 9.0 Linux router/gateway to simplify Network Access management. More efficient than RedHat build-in firewall management.

Features:

• Dynamic external IP address, helps for ISP with DHCP
• Supports internal network and DMZ
• Opens incoming ports only when service such as HTTPD or SSHD started
• Allow dynamic block/unblock a specific IP address

Get the latest stable version: dwn-firewall-1.0.tgz

Simple Host IDS

A simple host based Intrusion Detection System (HIDS) for RedHat 9.0 Linux. Allow to detect misbehavior such as failed basic HTTP authentication attempts or repetitive attempt to access non existing documents and block source IP address using script from DWN-FIREWALL.

Supports Apache HTTPD and uses MySQL as a backend.
