ProxyTunnel is a program that connects stdin and stdout to a server somewhere on the network, through a standard HTTPS proxy. We mostly use it to tunnel SSH sessions through HTTP(S) proxies, allowing us to do many things that wouldn't be possible without ProxyTunnel.


Password cracking utility for zip files


SSLScan queries SSL services, such as HTTPS, in order to determine the ciphers that are supported. SSLScan is designed to be easy, lean and fast. The output includes prefered ciphers of the SSL service, the certificate and is in Text and XML formats.


Tunnels TCP over UDP packets. Runs in user space on Linux, Solaris, Cygwin (with IPv6 extension), and native Win32.


PBNJ is a suite of tools to monitor changes on a network over time. It does this by checking for changes on the target machine(s), which includes the details about the services running on them as well as the service state. PBNJ parses the data from a scan and stores it in a database. PBNJ uses Nmap to perform scans.


iodine lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed.


ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.


This is a command-line tool that scans for open NETBIOS nameservers on a local or remote TCP/IP network, and this is a first step in finding of open shares. It is based on the functionality of the standard Windows tool nbtstat, but it operates on a range of addresses instead of just one. I wrote this tool because the existing tools either didn't do what I wanted or ran only on the Windows platforms: mine runs on just about everything.

Hping 3

hping is a free packet generator and analyzer for the TCP/IP protocol. Hping is one of the de-facto tools for security auditing and testing of firewalls and networks, and was used to exploit the Idle Scan scanning technique now implemented in the Nmap port scanner. The new version of hping, hping3, is scriptable using the Tcl language and implements an engine for string based, human readable description of TCP/IP packets, so that the programmer can write scripts related to low level TCP/IP packet manipulation and analysis in a very short time.


Vulnserver is a Windows based threaded TCP server application that is designed to be exploited. The program is intended to be used as a learning tool to teach about the process of software exploitation, as well as a good victim program for testing new exploitation techniques and shellcode.
