StMichael is a LKM that attempts to detect and divert attempts to install a kernel-module backdoor into a running linux system. This is done by monitoring the init_module and delete_module process for changes in the system call table. This is a experimental version, and a spin off from the Saint Jude Project.

Advanced NT Security Explorer (ANTExp) is an application for Microsoft Windows NT, Windows 2000 and Windows XP system administrators for finding holes in system security. It analyses user password hashes, and tries to recover plain-text passwords. If it's possible to recover the password in a reasonable time, the password should be considered to be insecure. ANTExp is very fast - tries about 900,000 passwords per second on a Pentium-III/450 CPU. Tested on Windows 95, Windows 98, Windows ME, Windows NT 4.0, Windows 2000, Windows XP.

Has an interactive mode and a web mode for greater functionality and options, shows network traffic sorted according to various criteria, displays traffic statistics, shows IP traffic distribution among the various protocols, analyses IP traffic and sorts it according to the source/destination, displays IP Traffic Subnet matrix (who's talking to who?), reports IP protocol usage sorted by protocol type.

Ngrep is a powerful network sniffing tool which strives to provide most of GNU grep's common features, applying them to all network traffic. ngrep is a pcap-aware tool that will allow you to specify extended regular expressions to match against data payloads of packets. It currently recognizes TCP, UDP and ICMP across Ethernet, PPP, SLIP, FDDI, and null interfaces, and understands bpf filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
