Xplico is an IP traffic decoder that extracts data from an Internet traffic capture. From a pcap file, it can extracts each email (POP, IMAP, and SMTP protocols), all HTTP content, VoIP calls (SIP, RTP, H323, MEGACO, MGCP), IRC, MSN, and so on. It isn't a packet sniffer or a network protocol analyzer, but rather an IP/Internet traffic decoder or network forensic analysis tool (NFAT).
WTMParse is a script originally intended for use in forensic examinations which parses WTMP files from Unix-like operating systems and generates a CSS-styled HTML report containing the login terminal, username, log start date, and login time/date in a table. It's good for postmortem forensic examinations or as a way of getting "last"-like information when you don't have the ability to boot the machine in question but can grab the wtmp.
GrokEVT is a collection of scripts built for reading Windows® NT/2K/XP/2K3 event log files. The scripts work together on one or more mounted Windows partitions to extract all information needed (registry entries, message templates, and log files) to convert the logs to a human-readable format.
DFF (Digital Forensics Framework) is a simple but powerful tool with a flexible module system which will help you in your digital forensics works, including file recovery due to error or crash, evidence research and analysis, etc. DFF provides a robust architecture and some handy modules.
Picviz is a parallel coordinates plotter which enables easy scripting from various types of input (such as tcpdump, syslog, iptables logs, or Apache logs) to visualize your data and discover interesting results quickly. Its primary goal is to graph data in order to be able to quickly analyze problems and find correlations among variables. With security analysis in mind, the program has been designed to be very flexible, able to graph millions of events.
MASTIFF is a static analysis framework which automates the process of extracting key characteristics from a number of different file formats. To ensure the framework remains flexible and extensible, a community-driven set of plugins is used to perform file analysis and data extraction. While originally designed to support malware, intrusion, and forensic analysis, the framework is well-suited to support a broader range of analytic needs. In a nutshell, MASTIFF allows analysts to focus on analysis rather than figuring out how to parse files.
check_websites is a very simple virus scanner for Web sites. It checks a document root directory for files with the .js extension and for codewords which might be a hint of defacement or SQL injection. This tool is made to run as a cronjob. There's no output on the screen, but it generates a logfile and mails output.
