If you've paid any attention to my past diaries, you know that I like to collect tools that are useful for packet analysis, malware analysis, memory analysis, log analysis, etc.  Here are a few of the new/interesting/different/updated tools or resources that I've looked at or heard about over the last several months since I last posted on the topic.

• PyFlag - Dr. Michael Cohen's python forensic and log analysis system (he even recently got it, at least partially, running under Windows).  Be sure to also take a look at the Volatility-PyFlag DFRWS Forensic Challenge submission.
• http://packetlife.net/ (an interesting blog) and especially http://packetlife.net/cheatsheets/
• psad - an interesting tool for attack detection using iptables logs
• Harlan Carvey had a post on his blog last month about analyzing browser artifacts that I thought was very good and pointed to some other tools.
• Cert.org had a nice blog post about ping sweeps in IPv6
• webFileScanner.pl - a pen test tool from 0x0e

Enjoy.
