Vulnerable Application

This post-exploitation module extracts clear text credentials from the Quassel IRC Client.

The Quassel IRC Client is avaialble from (https://quassel-irc.org/downloads).

This module extracts information from the quasselclient.ini file in the "AppData\Roaming\quassel-irc.org" directory.

This module extracts server information such as host name, port, account name, password and proxy password.

Verification Steps

Start MSF console
Get a Meterpreter session on a Windows system
use post/windows/gather/credentials/quasell_irc
Set SESSION 1
enter 'run' to extract credentials from all applications

Options

VERBOSE

By default verbose is turned off. When turned on, the module will show information on files which aren't extracted and information that is not directly related to the artifact output.

STORE_LOOT

This option is turned on by default and saves the stolen artifacts/files on the local machine, this is required for also extracting credentials from files using regexp, JSON, XML, and SQLite queries.

EXTRACT_DATA

This option is turned on by default and will perform the data extraction using the predefined regular expression. The 'Store loot' options must be turned on in order for this to take work.
