<h2>Description<a class="headerlink" href="#description" title="Permalink to this heading">¶</a></h2>
<p>The purpose of FastFind is to check for the presence of known indicators on large installed bases.</p>
<p>Since FastFind aims to analyze thousands of systems, it requires minimal interaction.
To achieve this goal, FastFind uses an XML configuration file embedded as a resource to specify the indicators to look for.
FastFind can leverage a collection of indicators to enable sophisticated indicator search.</p>
<p>FastFind can</p>
<ul class="simple">
<li><p>look up mounted file systems for known files using multiple indicators,</p></li>
<li><p>look up registry hives from known signature (keys, values, …), and</p></li>
<li><p>look up Windows object directory for known objects (Pipes, Events, …).</p></li>
</ul>
<p>FastFind does <strong>not</strong></p>
<ul class="simple">
<li><p>find sophisticated rootkits,</p></li>
<li><p>collect data for ulterior analysis, and</p></li>
<li><p>find traces of any other system compromise (i.e. it only searches for specific known threats).</p></li>
</ul>
<p>FastFind is a standalone executable: it does not require any installation prior to execution. It is currently supported by the following Windows versions:</p>
<ul class="simple">
<li><p>Windows XP SP2 (Win32, x64),</p></li>
<li><p>Windows Server 2003 SP3 (Win32, x64),</p></li>
<li><p>Windows Vista SP1, SP2 (Win32, x64),</p></li>
<li><p>Windows Server 2008 SP1, SP2 (Win32, x64),</p></li>
<li><p>Windows Server 2012 (Win32, x64),</p></li>
<li><p>Windows 7 RTM, SP1 (Win32, x64),</p></li>
<li><p>Windows 8 RTM (Win32, x64),</p></li>
<li><p>Windows Server 2012 NTFS volumes (Win32, x64),</p></li>
<li><p>Windows 8.1 RTM (Win32, x64),</p></li>
<li><p>Windows Server 2012 R2 (x64),</p></li>
<li><p>Windows Server 2016,</p></li>
<li><p>Windows Server 2019, and</p></li>
<li><p>Windows 10 RTM … 1903 (Win32, x64).</p></li>
</ul>
<p>FastFind is using the same MFT parser as NTFSInfo but specifically targets indicator lookup.
For details on the MFT parser, please refer to <a class="reference internal" href="fs_implem_details.html"><span class="doc">MFT parser configuration for details</span></a>.</p>

<section id="output">
<h2>Output<a class="headerlink" href="#output" title="Permalink to this heading">¶</a></h2>
<p>Upon successful execution, FastFind outputs the result of its findings in an XML file, with one element per file system, registry or Windows object match.
It can also output up to two CSV files: one for the file system matches and one for the object matches.</p>
<p>Here is a sample XML output from the tool:</p>

</ul>
<p>The MFT parser can be configured to include deleted records. This option can provide information about recently deleted file system entries.
This can, by design, incur unpredictable results (as we are using unreliable or partially deleted information).
One can generally assume that resident attributes for those entries are valid unlike nonresident attributes that are most likely quickly invalidated after the entry deletion.
Use the option value <code class="docutils literal notranslate"><span class="pre">resident</span></code> to limit parsed deleted entries to resident ones.</p>
