			<content:encoded><![CDATA[<p>[lang_fr]L&#8217;edition Janvier / Février du magazine <a href="http://www.ed-diamond.com/index_misc.php">MISC</a> est sortie, si vous ne connaissez pas c&#8217;est une revue qui paraît tous les 2 mois et qui traite uniquement de sécurité informatique sur tout type de plateforme.<br />
Dans ce premier numéro de 2010, il y a un article très intéressant sur l&#8217;injection de code dans Mac OS X, mais ce qui est particulièrement cool, c&#8217;est que les injections sont faites en 64-bit, et non en 32-bit comme on a l&#8217;habitude d&#8217;en voir <img src='http://whine.fr/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /><br />
L&#8217;article présente 2 méthodes d&#8217;injection, la classique injection de lib, et l&#8217;autre moins courante, le <strong>Thread Hijacking</strong>.<br />
Je ne vais pas reprendre l&#8217;artcile mais je vous invite à le lire si ces techniques vous intéressent.</p>
<p>Parmis les autres articles on retiendra le dossier qui parle de la lutte antivirale et de ses limites.[/lang_fr]<br />
[lang_en]MISC is a french magazine which talk about security.<br />
For the first edit of 2010 there is a very interesting article on Mac OS X code injection, it&#8217;s not something new, but what is really cool is that all the injection are 64-bit, and that&#8217;s pretty unusual <img src='http://whine.fr/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /><br />
The article presents 2 different methods, the first one is classic, it&#8217;s a simple dynamic library injection, but the second is much more interesting because it uses <b>Thread hijacking</b>.[/lang_en]</p>

			<content:encoded><![CDATA[<p>Y a toujours des boulets qui perdent leur mot de passe de session, du coup on voit souvent des questions du type <i>Comment réinitialiser son Mot de Passe</i>.<br />
La réponse est simple, peut-être trop d&#8217;ailleurs, on boot sur le DVD d&#8217;install et on le réinitialise, ouais mais le problème c&#8217;est que les boulets ils perdent aussi le DVD d&#8217;install, du coup ça devient un peu plus relou.<br />
La solution, on boot en <b>Single User (Pomme + S)</b>, Attention, le clavier est en <b>QWERTY</b>.<br />
Première chose à faire, on monte le disque en écriture :</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #000000; font-weight: bold;">/</span>sbin<span style="color: #000000; font-weight: bold;">/</span><span style="color: #c20cb9; font-weight: bold;">mount</span> <span style="color: #660033;">-uw</span> <span style="color: #000000; font-weight: bold;">/</span></pre></td></tr></table></div>

<p>Ensuite on peut changer le mot de passe :</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">passwd</span> NOM_DU_LOGIN</pre></td></tr></table></div>

<p>Vous rentrez le nouveau mot de passe 2 fois (rien ne s&#8217;affiche quand vous tapez, c&#8217;est normal..)<br />
Voilà le tour est joué, y a plus qu&#8217;à reboot.</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;">reboot</pre></td></tr></table></div>

<p>Hop on peut se re-logger, même si le plus simple c&#8217;est de ne pas perdre son password, mais bon&#8230;</p>
<p>see u.</p>

			<content:encoded><![CDATA[<p>Je me baladais sur google en cherchant des infos sur <a href="http://www.ntfs-3g.org/">ntfs-3g</a> pour Snow Leopard lorsque je suis tombé sur un <a href="http://forums.macrumors.com/showthread.php?t=785376">sujet</a> fort intéressant sur macrumors.<br />
Il y a un moment que l&#8217;on peut lire le NTFS sur Mac OS X, mais pour ce qui est de l&#8217;écriture il fallait passer par un driver tierce du style ntfs-3g ou <a href="http://www.paragon-software.com/fr/home/ntfs-mac/">Paragon NTFS</a>.<br />
Avec Snow Leopard il n&#8217;y a plus besoin de drivers en plus, vous pouvez écrire sur du NTFS de base, seulement par défaut l&#8217;option n&#8217;est pas activée.<br />
On va donc aller l&#8217;activer, pour ce faire, on a juste besoin du Terminal.<br />
<span id="more-216"></span><br />
Dans un premier temps si vous avez un driver pour l&#8217;écriture sur du NTFS installé, désinstallez le.</p>
<p>Ensuite on va récupèrer l&#8217;UUID du disque sur lequel on veut écrire :</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;">diskutil info <span style="color: #000000; font-weight: bold;">/</span>Volumes<span style="color: #000000; font-weight: bold;">/</span>NOM_DU_DISQUE</pre></td></tr></table></div>

<p>Cherchez la ligne contenant l&#8217;UUID et copiez le.</p>
<p>On continue en regardant si le fichier <b>/etc/fstab</b> existe :</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">ls</span> <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span> <span style="color: #000000; font-weight: bold;">|</span> <span style="color: #c20cb9; font-weight: bold;">grep</span> fstab$</pre></td></tr></table></div>

<p>Sur une installation par défaut le fichier n&#8217;existe pas, mais si vous possédiez un driver il est probable qu&#8217;il existe, si oui faites en une copie de sauvegarde.</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">cp</span> <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>fstab ~<span style="color: #000000; font-weight: bold;">/</span>Desktop<span style="color: #000000; font-weight: bold;">/</span></pre></td></tr></table></div>

<p>Enfin on va éditer le fichier <b>/etc/fstab</b>, le créer pour ceux qui ne l&#8217;ont pas.<br />
Je parle bien du fichier <strong>fstab</strong> et non <strong>fstab.hd</strong> !</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">nano</span> <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>fstab</pre></td></tr></table></div>

<p>On ajoute cette ligne :<br />
<b>UUID=uuid_du_disque none ntfs rw</b><br />
Si vous n&#8217;avez pas l&#8217;UUID du disque vous pouvez ajouter cette ligne à la place (possible sur un disque externe) :<br />
<b>LABEL=nom_du_disque none ntfs rw</b></p>
<p>On sauvegarde, <b>CTRL+X</b> suivi de <b>Y</b> (Pour ceux qui ont edité avec nano).</p>
<p>Dernière étape, le reboot.<br />
Voilà, vous devriez maintenant pouvoir écrire sur votre disque NTFS sans driver tierce <img src='http://whine.fr/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /><br />
On notera la réactivité de la chose, meilleur que ntfs-3g et la gestion de quelques attributs, notamment les fichiers cachés.</p>
<p>A noter que cette astuce n&#8217;est valable que pour Mac OS 10.6 et fonctionne indifféremment en kernel 32-bit ou 64-bit.</p>

			<content:encoded><![CDATA[<p>Un petit point sur Snow Leopard après 10 jours d&#8217;usage.<br />
Comme lors de la sortie de tout nouvel OS, il y a son lot de problème, et Snow Leopard n&#8217;a pas été epargné, pour preuve hier soir est sortie une première mise-à-jour, seulement 15 jours après la sortie de l&#8217;OS.<br />
<a href="http://support.apple.com/kb/HT3810?viewlocale=en_US">Liste des corrections</a><br />
<span id="more-215"></span><br />
On rajoute à cette liste la dernière version de flash, chose qui a fait parlé puisque 10.6 embarquait une version de flash antérieure à celle de Leopard&#8230; Mais que fait donc Apple ?<br />
Je n&#8217;ai personnellement pas eu de problèmes avec ce nouvel OS, mais au vu du nombre de problèmes constatés sur divers forums, on peut se demander si Apple n&#8217;a pas un peu baclé la sortie de son OS, juste pour devancer Windows 7, pas très glorieux.<br />
Pour limiter le nombre de problèmes il me paraît toutefois judicieux de faire une installation &#8216;propre&#8217; plutôt qu&#8217;une MaJ.</p>
<p>Bon je ne vais pas faire que whiner, vu que y a pas mal de trucs positifs aussi.<br />
- Premièrement, la réactivité et la fluidité de l&#8217;OS sont vraiment plaisantes.<br />
- Deuxièmement, le léger accent sur la sécurité, on a pu lire sur différents sites que 10.6 intégrait un pseudo anti-virus, il ne s&#8217;agit en réalité que d&#8217;un fichier .plist contenant la définition de 2 trojans, <b>OSX.RSPlug.A</b> et <b>OSX.Iservice</b>.<br />
Ce fichier semble être mis-à-jour uniquement lors des mises-à-jour systèmes, donc c&#8217;est un peu léger, surtout quand on sait que pleins de personnes ne font pas leur mises-à-jour.. et que de toutes façons Apple ne sortira pas une MaJ instantanément après la découverte d&#8217;un malware.<br />
<a rel="lightbox" href="http://whine.fr/wp-content/uploads/2009/09/xprotect.png"><img class="aligncenter" src="http://whine.fr/wp-content/uploads/2009/09/xprotect_thumb.png"/></a><br />
Autre petit plus, la protection des applications par défaut, en effet plus moyen de modifier / supprimer une application par défaut sans demande de mot de passe admin, même en étant logger en tant qu&#8217;admin.<br />
- Pour les devs, l&#8217;ajout du compilateur <a href="http://clang.llvm.org/">Clang</a>, l&#8217;ajout au C des closures (blocks).</p>

			<content:encoded><![CDATA[<p>Je vais vous présenter une nouvelle fonctionnalité de Snow Leopard dont on a peu entendu parler, la correction automatique de texte.<br />
Depuis 10.6, dans le panneau <b>International</b> des Préférences Système un nouvel onglet est apparu, <b>Texte</b>.<br />
Prenons un exemple simple, parfois lorsque l&#8217;on tape du texte il arrive que l&#8217;on inverse 2 lettres sur un mot assez fréquemment, c&#8217;est assez relou vu qu&#8217;il faut effacer la faute et retaper le texte.<br />
Ceux qui se servent de Word connaissent peut-être cette fonction qui permet de remplacer le mot qui contient la faute par le bon mot, l&#8217;onglet <b>Texte</b> sert exactement à ça.<br />
Admettons que je fasse souvent une faute sur le mot <i>perl</i>, et que je l&#8217;écrive <i>prel</i>.<br />
Dans l&#8217;onglet <b>Texte</b> j&#8217;ajoute le mot erroné, je lui fais correspondre le bon mot et le tour est joué.<br />
Lancez TextEdit faites la faute et vous verrez que le mot est automatiquement remplacé, plutôt pratique.<br />
Bien sûr ça ne marche que sur TextEdit, donc si vous ne l&#8217;utilisez pas vous ne pourrez bénéficier de cet agrément :/<br />

			<content:encoded><![CDATA[<p>Snow Leopard est sorti, Apple se targue d&#8217;avoir un système pleinement 64-bit (enfin..) et pourtant, seulement quelques machines peuvent booter avec un kernel 64-bit, les machines &#8216;pro&#8217;.<br />
Pour les personnes ayant une machine 64-bit et un EFI 64, il peut être frustrant de ne pas profiter d&#8217;un Kernel 64-bit, ce qui est mon cas.<br />
Il est néamoins possible d&#8217;outrepasser cette limite, ça relève un peu de la bidouille donc ne vous lancez pas tête baissée dedans, d&#8217;autant que pour l&#8217;utilisateur lambda il n&#8217;y a que peu d&#8217;intérêt.</p>
<p>Comment Apple a fait pour prévenir d&#8217;un boot en 64 ?<br />
Il y a juste une valeur hard-codée dans le fichier boot.efi qui empêche le boot en 64 selon le modèle de votre machine.<br />
Il va donc falloir modifier ce fichier pour permettre le boot en 64-bit, notez que je ne fais pas de SAV en cas de problème.<br />
<span id="more-209"></span><br />
Bon on va y aller pas à pas, de quoi avez vous besoin :<br />
- Un proc 64-bit toute la famille des c2d.<br />
- Un EFI 64, pour vérifier si votre EFI l&#8217;est, voir ci-dessous.</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;">ioreg <span style="color: #660033;">-l</span> <span style="color: #660033;">-p</span> IODeviceTree <span style="color: #000000; font-weight: bold;">|</span> <span style="color: #c20cb9; font-weight: bold;">grep</span> firmware-abi</pre></td></tr></table></div>

<p>- Etre admin de la machine.<br />
- Un editeur hexadecimal (<a href="http://www.versiontracker.com/dyn/moreinfo/macosx/10658">HexEdit</a> par exemple)<br />
- 2 ordis, ce n&#8217;est pas ogligatoire, mais en cas de problème si votre machine ne boot plus c&#8217;est mieux.</p>
<p>Première étape, on modifie le fichier de préférences <b>com.apple.Boot.plist</b> en ajoutant le flag <b>arch=x86_64</b></p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">nano</span> <span style="color: #000000; font-weight: bold;">/</span>Library<span style="color: #000000; font-weight: bold;">/</span>Preferences<span style="color: #000000; font-weight: bold;">/</span>SystemConfiguration<span style="color: #000000; font-weight: bold;">/</span>com.apple.Boot.plist</pre></td></tr></table></div>

<p>Ensuite on fait une copie du fichier <b>boot.efi</b> et on la renomme en boot-64.efi.</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1

<p>Voici le tableau contenant les valeurs qui nous intéressent (<a href="http://osxbook.com/blog/">Source</a>)</p>
<table border="1">

</table>
<p><br/><br />
Ouvrez boot-64.efi avec l&#8217;editeur hexadecimal et changez la ligne correspondant à votre machine.<br />
Pour ma part, étant sur un MacBook voici la ligne que j&#8217;édite :<br />
<i>0x266E0</i>:	38 47 01 00  00 00 00 00  <b>04</b> 00 00 00  00 00 00 00</p>
<p>Enregistrez et copiez le fichier boot-64.efi dans CoreServices.</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">cp</span> boot-64.efi <span style="color: #000000; font-weight: bold;">/</span>System<span style="color: #000000; font-weight: bold;">/</span>Library<span style="color: #000000; font-weight: bold;">/</span>CoreServices<span style="color: #000000; font-weight: bold;">/</span></pre></td></tr></table></div>

<p>Dernière étape, changer les informations de boot, pour cela on utilise la commande <a href="http://www.manpagez.com/man/8/bless/">bless</a>, après avoir changé les droits et les flags du fichier.</p>

<p>On reboot, si tout c&#8217;est bien passé, vous devriez être en 64-bit, vous pouvez le vérifier à l&#8217;aide de la commande <i>uname -a</i> ou dans les informations système.</p>
<p>Si votre machine ne boot plus, j&#8217;ai envie de dire owned&#8230; Plus sérieusement ré-utilisez la commande bless afin de rétablir le boot original, c&#8217;est là que le deuxième ordinateur devient utile.</p>

			<content:encoded><![CDATA[<p>Snow Leopard viens juste de sortir, et certaines personnes se demandent peut-être comment activer l&#8217;utilisateur root car cela diffère de Léopard.</p>
<p>En effet sous Leopard il suffisait de lancer l&#8217;application &#8216;Utilitaire d&#8217;annuaire&#8217;, mais cette application a disparue du dossier utilitaire sous 10.6.<br />
Elle a simplement changé de place, elle se trouve désormais dans le dossier /System/Library/CoreServices/<br />
A partir de là c&#8217;est comme sous Léopard, authentifiez vous et activez root, le tour est joué.</p>
<p>Il y a un autre moyen, dans Préférences Systèmes / Comptes, allez dans les options et cliquez sur le bouton joindre, là vous aurez la possibilité d&#8217;ouvrir Utilitaire d&#8217;Annuaire, voici les screens (mon OS est en anglais)</p>

<p>Enfin pour les geeks comme moi, il reste le terminal :</p>

			<content:encoded><![CDATA[<p>Je vois souvent des gens (des Apple fanboys en fait) qui disent Mac OS X est 64-bit, pas comme windows ou y a 2 versions blablabla..<br />
Qu&#8217;en est-il réellement ? ouvrons le terminal, une commande très pratique existe : <a href="http://www.linux-kheops.com/doc/man/manfr/man-html-0.9/man1/file.1.html">file</a>, essayons la sur <em>/bin/ls</em> pour commencer.</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #7a0874; font-weight: bold;">&#91;</span>Nyxouf<span style="color: #000000; font-weight: bold;">@</span>nyx0ufs-macbook ~<span style="color: #7a0874; font-weight: bold;">&#93;</span>$ <span style="color: #c20cb9; font-weight: bold;">file</span> <span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span><span style="color: #c20cb9; font-weight: bold;">ls</span>

<span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/</span><span style="color: #c20cb9; font-weight: bold;">ls</span> <span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #000000; font-weight: bold;">for</span> architecture ppc7400<span style="color: #7a0874; font-weight: bold;">&#41;</span>:	Mach-O executable ppc</pre></div></div>

<p>On voit que le binaire contient du code pour 2 architectures, intel et PowerPC (Universal Binaries), pas de trace de 64-bit.</p>
<p>Bon maintenant, essayons sur un truc un peu plus sérieux :</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #7a0874; font-weight: bold;">&#91;</span>Nyxouf<span style="color: #000000; font-weight: bold;">@</span>nyx0ufs-macbook ~<span style="color: #7a0874; font-weight: bold;">&#93;</span>$ <span style="color: #c20cb9; font-weight: bold;">file</span> <span style="color: #000000; font-weight: bold;">/</span>mach_kernel
<span style="color: #000000; font-weight: bold;">/</span>mach_kernel: Mach-O universal binary with <span style="color: #000000;">2</span> architectures
<span style="color: #000000; font-weight: bold;">/</span>mach_kernel <span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #000000; font-weight: bold;">for</span> architecture i386<span style="color: #7a0874; font-weight: bold;">&#41;</span>:	Mach-O executable i386
<span style="color: #000000; font-weight: bold;">/</span>mach_kernel <span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #000000; font-weight: bold;">for</span> architecture ppc<span style="color: #7a0874; font-weight: bold;">&#41;</span>:	Mach-O executable ppc</pre></div></div>

<p>J&#8217;ai le regret d&#8217;annoncer aux fanboys que leur kernel n&#8217;a rien de 64-bit, et qu&#8217;au final y a pas beaucoup d&#8217;applications 64-bit, listons les applications dans /bin et dans /usr/bin en filtrant la sortie avec <em>grep</em> :</p>

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #7a0874; font-weight: bold;">&#91;</span>Nyxouf<span style="color: #000000; font-weight: bold;">@</span>nyx0ufs-macbook ~<span style="color: #7a0874; font-weight: bold;">&#93;</span>$ <span style="color: #c20cb9; font-weight: bold;">file</span> <span style="color: #000000; font-weight: bold;">/</span>bin<span style="color: #000000; font-weight: bold;">/*</span> <span style="color: #000000; font-weight: bold;">|</span> <span style="color: #c20cb9; font-weight: bold;">grep</span> <span style="color: #000000;">64</span></pre></div></div>

<p>Résultat : nada.</p>

<p>Ca nous fait environ 50 binaires compatibles 64-bit sur plus de 900 dans ce répertoire.</p>
<p>La même commande dans /Applications nous montre que la seule application d&#8217;Apple 64-bit est Chess.app.</p>

<p>NB : Tous les tests ont été réalisés sur un MacBook4,1 C2D 2,4Ghz tournant sous Mac OS X 10.5.7.</p>
