I dont know what happened with the last one I did but thanks for the help.
Can someone explain the process AFTER the first Base64 encoding?
Here is the original footer.php:

Using a 64 encoder I get the following:

and
| Code: | | $lll=0;eval(base64_decode("JGxsbGxsbGxsbGxsPSdiYXNlNjRfZGVjb2RlJzs="));$ll=0;eval($lllllllllll("JGxsbGxsbGxsbGw9J29yZCc7"));$llll=0;$lllll=3;eval($lllllllllll("JGw9JGxsbGxsbGxsbGxsKCRvKTs="));$lllllll=0;$llllll=($llllllllll($l[1])<<8)+$llllllllll($l[2]);eval($lllllllllll("JGxsbGxsbGxsbGxsbGw9J3N0cmxlbic7"));$lllllllll=16;$llllllll="";for(;$lllll<$lllllllllllll($l);){if($lllllllll==0){$llllll=($llllllllll($l[$lllll++])<<8);$llllll+=$llllllllll($l[$lllll++]);$lllllllll=16;}if($llllll&0x8000){$lll=($llllllllll($l[$lllll++])<<4);$lll+=($llllllllll($l[$lllll])>>4);if($lll){$ll=($llllllllll($l[$lllll++])&0x0f)+3;for($llll=0;$llll<$ll;$llll++)$llllllll[$lllllll+$llll]=$llllllll[$lllllll-$lll+$llll];$lllllll+=$ll;}else{$ll=($llllllllll($l[$lllll++])<<8);$ll+=$llllllllll($l[$lllll++])+16;for($llll=0;$llll<$ll;$llllllll[$lllllll+$llll++]=$llllllllll($l[$lllll]));$lllll++;$lllllll+=$ll;}}else$llllllll[$lllllll++]=$llllllllll($l[$lllll++]);$llllll<<=1;$lllllllll--;}eval($lllllllllll("JGxsbGxsbGxsbGxsbD0nY2hyJzs="));$lllll=0;eval($lllllllllll("JGxsbGxsbGxsbD0iPyIuJGxsbGxsbGxsbGxsbCg2Mik7"));$llllllllll="";for(;$lllll<$lllllll;){$llllllllll.=$llllllllllll($llllllll[$lllll++]^0x07);}eval($lllllllllll("JGxsbGxsbGxsbC49JGxsbGxsbGxsbGwuJGxsbGxsbGxsbGxsbCg2MCkuIj8iOw=="));eval($lllllllll); |
It is from here, that I am stuck
If its too much of a hassle to explain I understand and thanks for the help.

You were almost there  You shouldn't decode the $o string though. Just gotta follow the PHP code you get by decoding the second string. The easiest way is to simply change the last eval() into highlight_string(). If you'd decode the file manually you'd see the variables change until you get to that last eval(), which actually displays the page. So a simple highlight_string() would reveal the PHP code  |

| It's a bit confusing with the different 11... variables, I admit But that's the intention of the creaters of this encoding scheme, to make it harder to decode |

1. Basic PHP knowledge (google)
2. eval()
3. base64_decode() & base64_encode()
4. highlight_string()
is about all you need |
