Fping

Fping : A parallel ping scanning program
fping is a ping(1) like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping. Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion. If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

VMware

VMware : Multi-platform Virtualization Software
VMware virtualization software lets you run one operating system within another. This is quite useful for security researchers who commonly need to test code, exploits, etc on multiple platforms. It only runs on Windows and Linux as the host OS, but pretty much any x86 OS will run inside the virtualized environment. It is also useful for setting up sandboxes. You can browse from within a VMware window so the even if you are infected with malware, it cannot reach your host OS. And recovering the guest OS is as simple as loading a “snapshot” from prior to the infection. VMware player (executes, but can’t create OS images) and VMWare Server (partitions a physical server machine into multiple virtual machines) were recently released for free. Another interesting virtualization system (Linux focused) is Xen.

Honeyd

Honeyd : Your own personal honeynet
Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses on a LAN for network simulation. It is possible to ping the virtual machines, or to traceroute them. Any type of service on the virtual machine can be simulated according to a simple configuration file. It is also possible to proxy services to another machine rather than simulating them. It has many library dependencies, which can make compiling/installing Honeyd difficult.

cheops / cheops-ng : Gives a simple interface to many network utilities, maps local or remote networks and identifies OS of machines
Cheops provides the functionality of many network utilities through a comfortable, powerful GUI. It has host/network discovery functionality as well as OS detection of hosts. Cheops-ng has the ability to probe hosts to see what services they are running. On some services, cheops-ng is actually able to see what program is running for a service and the version number of that program. The original Cheops program is currently not being developed or maintained so users are advised to use cheops-ng.

ClamAV

ClamAV : A GPL anti-virus toolkit for UNIX
ClamAV is a powerful AntiVirus scanner focused towards integration with mail servers for attachment scanning. It provides a flexible and scalable multi-threaded daemon, a command line scanner, and a tool for automatic updating via the Internet. Clam AntiVirus is based on a shared library distributed with the Clam AntiVirus package, which you can use with your own software. Most importantly, the virus database is kept up to date.

Fport

Fport : Foundstone’s enhanced netstat
Fport reports all open TCP/IP and UDP ports on the machine you run it on and shows what application opened each port. So it can be used to quickly identify unknown open ports and their associated applications. It only runs on Windows, but many UNIX systems now provided this information via netstat (try ‘netstat -pan’ on Linux). Here is a PDF-Format SANS article on using Fport and analyzing the results.

Arpwatch

Arpwatch : Keeps track of ethernet/IP address pairings and can detect certain monkey business
Arpwatch is the classic ARP man-in-the-middle attack detector from LBNL’s Network Research Group. It syslogs activity and reports certain changes via email. Arpwatch uses LibPcap to listen for ARP packets on a local ethernet interface.

LSoF

LSoF : LiSt Open Files
This Unix-specific diagnostic and forensics tool lists information about any files that are open by processes currently running on the system. It can also list communications sockets open by each process. For a Windows equivalent, check out Process Explorer from Sysinternals.

Google

Google : Everyone’s Favorite Search Engine
While it is far more than a security tool, Google’s massive database is a good mind for security researchers and penetration testers. You can use it to dig up information about a target company by using directives such as “site:target-domain.com” and find employee names, sensitive information that they wrongly thought was hidden, vulnerable software installations, and more. Similarly, when a bug is found in yet another popular webapp, Google can often provide a list of vulnerable servers worldwide within seconds. The master of Google hacking is Johny Long. Check out his Google Hacking Database or his excellent book: Google Hacking for Penetration Testers.

Sam Spade

JraNil — Sun, 05 Apr 2009 08:49:14 +0000

Sam Spade : Freeware Windows network query tool
Sam Spade provides a consistent GUI and implementation for many handy network query tasks. It was designed with tracking down spammers in mind, but can be useful for many other network exploration, administration, and security tasks. It includes tools such as ping, nslookup, whois, dig, traceroute, finger, raw HTTP web browser, DNS zone transfer, SMTP relay check, website search, and more. Non-Windows users can enjoy online versions of many of their tools.
