Fierce domain scan was born out of personal frustration after performing a web application security audit. It is traditionally very difficult to discover large swaths of a corporate network that is non-contiguous. It's terribly easy to run a scanner against an IP range, but if the IP ranges are nowhere near one another you can miss huge chunks of networks.

First what fierce is not. Fierce is not an IP scanner, it is not a DDoS tool, it is not designed to scan the whole internet or perform any un-targeted attacks. It is meant specifically to locate likely targets both inside and outside a corporate network. Only those targets are listed. No exploitation is performed. Fierce is a reconnaissance tool. Fierce is a perl script that quickly scans domains (usually in just a few minutes, assuming no network lag) using several tactics.

Today, the Rob McMillen of the Honeynet project announced the release of a beta version of Honeynet on bootable CD. Honeynet works as a network security appliance to give detailed information about the state of your network. More information can be found from the Honeynet article titled "Know Your Enemy:Honeynets". The ISO images for this project can be downloaded here

Recently I was searching for a keylogger and stumbled upon an opensource project called Regload. Upon installation the program (regload) copies itself to the windows root directory and sets /currentversion/run to execute c:windowsregload.exe on boot. As soon as keyboard input is recieved regload copies the data to c:windowsregload.hlp which is just a simple text file. What's more is that the program is not detected as spyware or a trojan by Norton AV, Adaware, or spybot (search and destroy). The program is avalable for download at sourceforge.net. Also, various sources have combined the windows based BLAT smtp engine so that the regload.hlp is automaticly emailed to a specified email address. See more info here
