			<content:encoded><![CDATA[<p>Since I couldn&#8217;t find an all-in-one guide anywhere out there, I&#8217;m going to write up a short post on how to enable smart card logon in a Microsoft Active Directory environment.</p>
<p>It&#8217;s short since I&#8217;m a little bit lazy in documenting every step (these are mainly notes for myself), but if enough people request, I&#8217;ll expand this post to include more details.</p>
<p>Requirements:<br />
- Active Directory (Windows 2003 and up). You cannot have smartcard login without some sort of directory service &#8211; that defeats the purpose of PKI.<br />
- Smart card, smart card reader, and its middleware / drivers installed wherever you will be logging into the domain.</p>
<p>Phases:<br />
I. Install Certificate Services on a server that is part of the domain, configure a root CA, enable the Smartcard Logon certificate template<br />
II. Create an GPO that auto-enrolls domain machines so that all your domain machines get a certificate &#038; can renew them automatically. Make sure computers and all domain controllers have a certificate.<br />
III. Logon to a domain machine, open Certificates snap-in for the current user, request new certificate, select &#8220;advanced options&#8221;, pick the CSP for your smartcard and complete the request.<br />
IV. Test logins <img src='http://darwin-mach.net/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>You remember about all those scams I was posting about? (Then stopped posting about since I got lazy).</p>
<p>Now there&#8217;s a new discovery: A Russian hacker who says he&#8217;s in New Zealand is selling the username &#038; passwords of Facebook accounts ranging from $35 to $65, depending on how many friends each account has. He claims he has 1.5 million account credentials, 700,000 of which has already been sold.</p>
<p>Here&#8217;s the link to the article&#8217;s source: <a href="http://www.nzherald.co.nz/connect/news/article.cfm?c_id=1501833&#038;objectid=10640757">http://www.nzherald.co.nz/connect/news/article.cfm?c_id=1501833&#038;objectid=10640757</a>.</p>
<p>Again, please be very careful when you are using Facebook!</p>

			<content:encoded><![CDATA[<p>I recently broke out my Netgear WNDA3100 adapter that I bought a while ago to replace my old Netgear WG111 that I used to use for cracking wireless networks. Granted, the WG111 was reliable, but the reasons for the replacement are obvious: the WNDA3100 is dual-band and supports 802.11n. But for beginners who don&#8217;t want to shell out as much money nor spend extra time getting a wireless card to work properly, the WG111 is still the best choice.</p>
<p>Spend extra time to get the WNDA3100 to work properly? Yes, it didn&#8217;t quite readily work with BT4 (and probably not with other distros running the same kernel version). After doing some searching, I found a <a href="http://www.backtrack-linux.org/forums/backtrack-howtos/1042-how-get-ar9170-chipset-usb-adapter-working.html">thread</a> on backtrack-linux.org&#8217;s forum that allows my new adapter to work, with full monitor mode &#038; packet injection capabilities. For a matter of record &#038; for easy searching, I&#8217;ll document the directions below.</p>
<p>These instructions work for any Atheros AR9170 based cards:</p>
<p>    * Arcadyan &#8211; WN7512<br />
    * Atheros &#8211; 9170<br />
    * Atheros &#8211; TG121N<br />
    * AVM &#8211; FRITZ!WLAN USB Stick N<br />
    * AMV &#8211; FRITZ!WLAN USB Stick N 2.4<br />
    * Cace &#8211; Airpcap NX<br />
    * D-Link &#8211; DWA 160A1<br />
    * D-Link &#8211; DWA 160A2<br />
    * IO-Data &#8211; WNGDNUS2<br />
    * Netgear &#8211; WNDA3100<br />
    * Netgear &#8211; WN111 v2<br />
    * Planex &#8211; GWUS300<br />
    * Sphairon &#8211; Homelink 1202<br />
    * TP-Link &#8211; TL-WN821N v2<br />
    * Z-Com &#8211; UB81 BG<br />
    * Z-Com &#8211; UB82 ABG<br />
    * Zydas &#8211; ZD1221<br />
    * Zyxel &#8211; NWD271N</p>
<p>IMPORTANT: please note that the hardware revisions matter, especially for the WNDA3100 that I&#8217;m working with. The WNDA3100v2 uses a Broadcom chipset instead, which has some other issues &#038; corresponding remedies I won&#8217;t be discussing here.</p>
<p>Anyways&#8230;</p>
<p>1.) Download the patched firmwares <a href="http://www.kernel.org/pub/linux/kernel/people/mcgrof/firmware/ar9170/ar9170.fw">ar9170.fw</a>, <a href="http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=blob_plain;f=ar9170-1.fw;hb=master">ar9170-1.fw</a>, and <a href="http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=blob_plain;f=ar9170-2.fw;hb=master">ar9170-2.fw</a> and place them into /lib/firmware.</p>
<p>2.) Download <a href="http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.32/compat-wireless-2.6.32.3.tar.bz2">compat-wireless-2.6.32.3.tar.bz2</a> and untar it to your favorite location.</p>
<p>3.) Run the following in the terminal:<br />
<code>cd compat-wireless-2.6.32.3<br />
make<br />
make install<br />
make unload</code></p>
<p>*If you get a &#8220;No such file or directory&#8221; error when you run make, run:<br />
<code>ln -s /usr/src/linux /lib/modules/2.6.30.9/build</code></p>
<p>I didn&#8217;t get the error so I didn&#8217;t run it.</p>
<p>4.) Add &#8220;blacklist arusb_lnx &#8221; to the end of /etc/modprobe.d/blacklist. This will prevent the loading of the buggy/incorrect drivers and load the proper ones instead.</p>
<p>5.) On line 174 of /usr/sbin/airmon-ng, change &#8220;xar9170&#8243; to &#8220;xar9170usb&#8221;. This will tell airmon from the aircrack suite to use the new drivers.</p>
<p>6.) Save all files and reboot.</p>
<p>Test it using the following:</p>
<p>1.) Plug in your adapter (WNDA3100 in my case) and start the networking service.<br />
<code>/etc/init.d/networking start</code></p>
<p>2.) Run:<br />
<code>airmon-ng start <em>wlan0</em></code><br />
Replace <em>wlan0</em> with your wireless interface&#8217;s name. This will put your card into monitoring mode.</p>
<p>3.) Run:<br />
<code>aireplay-ng -9 wlan0</code><br />
The -9 parameter means &#8211;test for short. This should show you some output with the APs found, whether injection was successful, etc.</p>
<p>Enjoy!</p>
<p>These new firmwares and drivers are likely to be incorporated in a newer version of the kernel, and thus later releases of *nix distros, hopefully eliminating the need for a large portion of this hack.</p>

			<content:encoded><![CDATA[<p>Well you know about the previous Dell Facebook scam? (<a href="http://darwin-mach.net/blog/2009/12/10/dell-promotion-facebook-scam/">http://darwin-mach.net/blog/2009/12/10/dell-promotion-facebook-scam/</a>) This one&#8217;s worse, but uses the exact same code, which does the exact same thing.</p>
<p>The theme now is that it claims to install &#8220;Profile Spy&#8221;, to help you see who&#8217;s looking at your profile, etc, but THERE IS NO SUCH THING. There&#8217;s only a few apps that really do this, but it requires your visitors also install the app, for the sake of their own privacy.</p>
<p>So&#8230; about 900,000 people have joined the Facebook group as of writing, and I reported it to Facebook again. We&#8217;ll see how long it takes them.</p>
<p>Here&#8217;s the link to the most recent scam &#8211; http://www.facebook.com/group.php?gid=209645259791 (you have to click on the &#8220;read more&#8221; link).</p>
<p>There was also another previous one before this one, but after the Dell one, involving &#8220;Crimson Labs&#8221; and a giveaway of iMacs.</p>
<p>Please! READ EVERYTHING CAREFULLY BEFORE YOU SAY YES. If anything looks suspicious or doesn&#8217;t make sense, well&#8230; <img src='http://darwin-mach.net/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Hi all,</p>
<p>I just wanted to alert you on a new scam that is going around on Facebook. It comes in the form of an invite to a group called &#8220;Dell Laptop Giveaway (1 in 2 people win one Laptop)&#8221; at http://www.facebook.com/group.php?gid=355563360211</p>
<p>BEWARE! The instructions stated actually collects your entire friends list and spams them with this invite and in no way enters you into any sweepstakes. This is another classic example of a deal too good to be true. As of writing this post, about 47000 people have joined the group and likely fell for this trick.</p>
<p>Resolution: IGNORE the invite and help spread the word about it. Do NOT do what the instructions tell you to do.</p>
<p>EDIT (11:53 EST): Looks like Facebook took down that rather quickly after I reported it. But still a lesson to be learned about carefully reading what you see.</p>
<p><span id="more-6"></span>&#8212;</p>
<p>In depth explanation&#8230;</p>
<p>The stated instructions are as follows:</p>
<blockquote><p>Hello! This is a promotional offer from Dell (www.dell.com). In order to promote our activity on Facebook we have decided to give away 1 free Laptop (value of 450 dollars). For every one person (out of two people) who promotes this group will win 1 of 3 Dell Inspiron models. In order to be eligible you will have to complete the following:</p>
<p>1. Click &#8216;Invite People to Join&#8217;<br />
2. Paste<br />
javascript:elms=document.getElementById(&#8216;friends&#8217;).getElementsByTagName(&#8216;li&#8217;);for(var fid in elms){if(typeof elms[fid] === &#8216;object&#8217;){fs.click(elms[fid]);}}</p>
<p>Into your URL bar and press enter!<br />
3. Send invites!</p>
<p>Your insertion into the competition is automatic as you complete the steps above. Both winners and losers are contacted via private message if they win a free laptop.</p></blockquote>
<p>Let&#8217;s take a look step by step.</p>
<p>1.) Opens the invite window with a full list of all your Facebook friends.</p>
<p>2.) Runs a JavaScript code to obtain a list of all your friends</p>
<p>3.) Tells you to send this scam out.</p>
<p>I have not determined which browsers &amp; versions are affected by this exploit &#8211; just don&#8217;t do it, use your common sense.</p>
<p>If you have the urge to take an extra step to help silence this scam, please report it to Facebook <img src='http://darwin-mach.net/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
