BsdScan is a light-weight port-scanner designed for the BSD operating system. It currently supports scanning single hosts, subnets, logging results, scanning ports in a random order, specifying a port range, and a speed option to only scan commonly used ports.

Nutcracker is a simple, fast, and effective password cracker for UNIX and Linux systems. It is faster than the other crackers available. Disabled accounts and accounts with no password are detected. Results are shown in a nicely-formatted table. A sample password file and dictionary file are included, although you can use any word list you wish (including the file '/usr/dict/words' included with most Linux distributions). Nutcracker will work with '/etc/passwd' or '/etc/shadow' files.

Inspired by ColorLogs, acl (Advanced Color Logs) has advanced parsing capabilities, including multiple search strings and negative search strings (matches if the string is not found in the line). It's very useful for highlighting important or non-standard messages from daemons, while not highlighting standard status messages from the same daemons.

Internet Explorer 5.01 under Windows 95 and 5.5 under WinNT 4.0 (suppose other versions are also vulnerable) allows circumventing "Cross frame security policy" by accessing the DOM of "old" documents using IMG SRC="javascript:..." and a design flaw in IE. This exposes the whole DOM of the target document and opens lots of security risks. This allows reading local files, reading files from any host, window spoofing, getting cookies, etc. Demonstration available here.
