Ident Scan 0.1 Source [sig]

This program connects to an identd server and asks for the information. This is an unintended consequence of the design of the server.

Identd is an interesting program. It searches /proc/net/tcp for a matching entry. The input is easy enough for a human to input into telnet if they have the localport and the remoteport. We get the localport from getsockname() and the remote port is the port that we are connected to. This will give us the user that is running the command.

Although AltBot seems to be awesome and perfect, it is a very new project and has a long ways to go. There are a lot of improvements that would make AltBot quite excellent. Look for them coming soon.

MD5 Collision Parser 0.1 Source [sig]
MD5 Collision Data Example [sig]
MD5 Collision Generation Homepage

This program parses the output of an MD5 Collision Generation program. It creates two binaries with the same md5sum. Hopefully this will allow people to put MD5 into a deep grave with a dozen nails in the coffin.

I went for quick and dirty. This python program is not secure. In fact, a person should not use this until after looking at both the source and the data. The program uses an eval() call on the data.

Netmap2 Neg9 Project

The Network Mapping project (also known as Neg9 UW Network Project) plans to develop tools to report on the usage of public networks through active scanning of ports. The first two tools are known as netmap1. It uses Nmap to discover available hosts and discover open ports on the hosts. Netmap1 involves two tools that can be run as part of a script. parse_ping1.py and parse_port1.py are run by the script scan_full1.sh. The output of the script are a set of xml files and records in a MySQL database.
