<p>And this is very easy. Just run the command</p>
<pre><code>!misc last --regexp m/(.*\w){512}/</code></pre>
<p>where ! is the prefix character.</p>
<p>Misc is loaded by default and cannot be unloaded without modifying the config.</p>

<p>Everyone can also make the bot count an equation, which brings it and the host computer down.</p>
<p>For example:</p>
<pre><code>!math calc factorial(999999)</code></pre>

<p>I don't have example command for this, but it happens by nesting &quot;format cut&quot; and &quot;misc tell&quot;.</p>
<p>What does this mean? Anyone can tell the bot to ghost someone else on same account, take over a channel by telling the bot to give flags (if it has correct flags), change password of the account and everything else what you do with network services.</p>

<p>This doesn't mean only things like CTCP actions (also known as /me), but known problems with old routers ( FF ? DCC SEND “ff???f??????????????” 0 0 0 ) which make them reconnect to the internet.</p>
<p>Usage:</p>
<pre><code>!web title &lt;malicious.page.here&gt;
!web fetch &lt;malicious.page.here&gt;</code></pre>
<p>Note that web fetch is disabled by default.</p>

<p>The first issue has been also used to take down some of <a href="https://wiki.ubuntu.com/IRC/Bots">Ubuntu IRC bots</a> several times. At least UbotX (I don't remember the number) and meetingology.</p>

<p>Some of them are fixed in git repository, but most people aren't using it.</p>
<h2 id="how-to-avoid-them">How to avoid them?</h2>
<p>You can add anticapability for these commands using &quot;owner defaultcapability&quot;, but that is only a temporary solution. There can also be other issues.</p>
<p>There are also two active Supybot forks, known as <a href="https://github.com/ProgVal/Limnoria">Limnoria</a> and <a href="http://sourceforge.net/apps/mediawiki/gribble/index.php?title=Main_Page">Gribble</a>, which are actively developed and have fixed these issues. If you want permanent solution, you should install either of them.</p>
<p>I recommend <a href="https://github.com/ProgVal/Limnoria">Limnoria</a>, because it seems to be more active (activity of <a href="http://sourceforge.net/apps/mediawiki/gribble/index.php?title=Main_Page">Gribble</a> isn't announced anywhere) and it has additional commands, translations and new plugin called <a href="https://github.com/ProgVal/Limnoria/tree/master/plugins/PluginDownloader">PluginDownloader</a>, which makes installing of 3rd party plugins easy. Ohloh supports comparing different projescts, <a href="https://www.ohloh.net/p/compare?project_0=Limnoria&amp;project_1=Gribble%3A+Support+Bottie&amp;project_2=Supybot">here is comparsion of Limnoria, Gribble and Supybot</a>.</p>
<p><strong>If you use Debian/Ubuntu or any Debian based distribution, you can get <a href="http://builds.progval.net/limnoria/limnoria-master-HEAD.deb">stable version of Limnoria here</a> or <a href="http://builds.progval.net/limnoria/limnoria-testing-HEAD.deb">testing version here</a>.</strong></p>
<p>The links above should always be the latest version of Limnoria and they are updated daily.</p>

Add GA. I am interested in seeing does anyone ever even look at these pages, but most of Supybot users who are on their channels have probable opted out of analytics or have extension to do that.
