cookietools is comprised of three pieces. First, the cookiesniffer, which is a simple and powerful cookie sniffer that recognizes (through heuristics) and reconstructs (through libnids) new and existing HTTP connections, parsing any valid or partially valid HTTP message. The output is a set of files containing the gathered information with time-stamps in a format that can be trivially searched and parsed with standard UNIX tools such as grep, awk, cut and sed. It supports wireless (AP_DLT_IEEE802_11) networks. Second, there is a set of bash scripts that are used to quickly analyze the logs of cookiesniffer. In addition to this, there is the cookieserver that allows you to impersonate the cookies of someone else in your browser using the logs of cookiesniffer. This attack is also called "side-jacking", "cookie replay attack" and "HTTP session hijacking".
