AutoScan-Network is a fast graphical network scanner. Useful for detecting unauthorized network access as well mapping known network devices. AutoScan has been ported to run on OSX, Linux, and Windows among other operating systems.

• Fast network scanner
• Automatic network discovery
• TCP/IP scanner
• Wake on lan functionality
• Multi-threaded Scanner
• Port scanner
• Low surcharge on the network
• VNC Client
• Telnet Client
• SNMP scanner
• Simultaneous subnetworks scans without human intervention
• Realtime detection of any connected equipment
• Supervision of any equipment (router, server, firewall...)
• Supervision of any network service (smtp, http, pop, ...)
• Automatic detection of known operatic system (brand and version), you can also add any unknown equipment to the database
• The graphical interface can connect one or more scanner agents (local or remote)
• Scanner agents could be deployed all over the network to scan through any type of equipment (router, NAT, etc)
• Network Intruders detection (in intruders detection mode, all new equipments blacklisted)
• Complete network tree can be saved in a XML file.
• Privileged account is not required


Kismet is a pretty decent tool to have in your wireless arsenal.
It's mostly used for identifying wireless networks in the area and gaining as much information about them as possible even if the information is not supposed to be available.
This helps drastically when you start to actually attack the network/device with aircrack or something similar, you already have all the information you need.

Feature set:
802.11b, 802.11g, 802.11a, 802.11n sniffing
Standard PCAP file logging (Wireshark, Tcpdump, etc)
Client/Server modular architecture
Multi-card and channel hopping support
Runtime WEP decoding
Tun/Tap virtual network interface drivers for realtime export of packets
Hidden SSID decloaking
Distributed remote sniffing with Kismet drones
XML logging for integration with other tools
Linux, OSX, Windows, and BSD support (devices and drivers permitting)


I believe, ettercap was a tool used a lot more often before things like wireshark and cain and abel came out or at least "got big".
It has support for a lot of different platforms, but it's main job is sniffiing the network and manipulating where the traffic goes or how it gets there thus allowing you to perform MiTM attacks easily. It features filtering just like wireshark and is able to dissect protocols just as well.

Winsock Packet Editor (WPE) Pro

Winsock Packet Editor (WPE) Pro is a packet sniffing/editing tool which is generally used to hack multiplayer games. WPE Pro allows modification of data at TCP level. Using WPE Pro one can select a running process from the memory and modify the data sent by it before it reaches the destination. It can record packets from specific processes, then analyze the information. You can setup filters to modify the packets or even send them when you want in different intervals.


Scapy is a packet manipulator used for crafting packets, sending packets, sniffing them etc. Also runs on Linux and Windows.

Cain and Abel

Windows password cracker, capable of cracking a variety of hashes, as well as arp poisoning, sniffing the network, etc.. to obtain those password hashes in the first place.
