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

It is from here, that I am stuck

If its too much of a hassle to explain I understand and thanks for the help.
Have a great day

You were almost there Smile 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 Wink

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

1. Basic PHP knowledge (google)
2. eval()
3. base64_decode() & base64_encode()
4. highlight_string()

is about all you need Smile
