&#8211;<span style="color: #000000;">Avira</span><br />
&#8211;<span style="color: #000000;">Bitdefender</span><br />

&#8211;<span style="color: #000000;">ESET</span><br />
&#8211;<span style="color: #000000;">F-Secure</span></p>
<p>Rezultatele au fost prezentate la conferinta <a href="http://www.syscan360.org/en/" target="_blank"><span style="color: #000000;">SyScan 360</span></a> din Beijing din iulie. In prezentare, Koret ilustreaza cum din cauza previlegiilor administrative oferite AV-urilor pot aparea probleme de securitate. Probleme ce pot fi exploatate de catre virusi.</p>
<blockquote><p><em>“AV engines <span id="92bc656a-32c7-492f-8faf-ca373a165230" class="GINGER_SOFTWARE_mark"><span id="37763b6c-094b-4603-b892-2735298f53eb" class="GINGER_SOFTWARE_mark"><span id="b89cab9e-fa11-4a1b-9aa5-1d63e6cb05e1" class="GINGER_SOFTWARE_mark"><span id="2ba694cf-093c-42bb-9c5b-d51f6237cafc" class="GINGER_SOFTWARE_mark"><span id="1255e5e1-57fe-4d62-9255-45c249abc70c" class="GINGER_SOFTWARE_mark"><span id="187d7726-c4a0-4f12-bd96-6a68762e354f" class="GINGER_SOFTWARE_mark">makes</span></span></span></span></span></span> your computer more vulnerable with a varying degree of performance penalty. The AV engine is as vulnerable to zero day attacks as the applications it tries to protect from.”<br />
</em></p></blockquote>
<p>Deci cu cat o aplicatie AV are mai multe drepturi administrative cu atat aria problemelor ce pot fi exploatate de virusi se mareste.</p>
<blockquote><p><em>“If the application is local: your local attack surface increased. If the application is remote: your remote attack surface increased. If your application runs with the highest privileges, installs kernel drivers, a packet filter and tries to handle anything your computer may do<span id="549cddcb-0e4d-4da9-aaf6-97b87423a28f" class="GINGER_SOFTWARE_mark"><span id="dc630d1c-c27b-4138-9846-f5de936ae7bd" class="GINGER_SOFTWARE_mark"><span id="8c5cbe96-e282-4062-ab14-1fb29f01f029" class="GINGER_SOFTWARE_mark"><span id="9306dca6-0ab0-4008-908f-b61901104a90" class="GINGER_SOFTWARE_mark"><span id="755d6be7-8cb1-487e-a64f-abba484028a2" class="GINGER_SOFTWARE_mark"><span id="fc81f020-2555-4f74-9e6a-58837d6607ae" class="GINGER_SOFTWARE_mark">…</span></span></span></span></span></span>Your attack surface dramatically increased.”</em></p></blockquote>
<p>O importanta problema de securitate este considerata si partea de update-uri, mai exact modul cum se realizeaza acest demers. Update-urile de AV nu sunt semnate iar acest lucru poate fi exploatat.</p>
<p>Concluzia este destul de neagra si sansele ca lucrurile sa se schimbe in bine sunt destul mici iar Joxean Koret incheie prezentarea cu o concluzie destul de pesimista dar pe cat se poate de reala.</p>
<blockquote><p><em><span style="color: #000000;">“<span id="abc2c769-3112-4c0f-8ec1-b3ca611d5460" class="GINGER_SOFTWARE_mark">Some</span> AV companies don’t give a f**k about security in their products,” <span id="3384bc52-2240-4c1f-8248-4ce498563487" class="GINGER_SOFTWARE_mark"></span></span></em></p></blockquote>

<p>Urmeaza ca intr-un viitor articol sa incercam sa gasim variantele optime sa ne protejam de virusi cu sau fara ajutorul programelor de AV cu real-time detection. Ideea de baza din ce am scris mai sus sau ce ar trebuie sa va ramana voua din acest articol este sa nu stati linistiti pe motiv ca aveti AV instalat cu update-urile la zi ca degeaba il aveti. Am avut experiente nasoale cu majoritatea AV-urile enumerate mai sus si rezolvarile nu au venit din partea lor. Dar despre lucrurile astea o sa vorbim altadata.</p>
