I have got a Joomla site that got hacked and I am looking at the server logs and I see something like:

GET /bind.php ho=mx01.1and1.es&po=25&ma=cristina%40bpmlighting.com&lo=cristina&pa=cristbpm2013&mt=johnkarpan%40yahoo.com&fn=Dr.+Sue+Metts&or=docswgacm&eh=bpmlighting.com&sd= 80 - HTTP/1.0 - - - mywebsite.com 500 0 64 0 544 308

I guess that is a hit on bind.php - I am not sure what the "ho=" stands for. Can anyone clarify?

I believe that's the Request URI, or the page that was loaded from your server. It gave a 500 error (which means nothing was executed), but it looks like an attempted hack of some kind. Give me a few minutes, and I'll URL decode the string and see what they were trying to do and tell you if you really need to worry or not.

UPDATE: I'm not entirely sure what they were trying t do, but it looks like they were looking for general vulnerabilities. I'd recommend that you:

  1. immediately check that particular file for any lines like eval(base64_decode(Long string of seemingly-random text));. This is usually a PHP shell, and gives anybody full access to your server. They can be clever about hiding it, so do a search in your program for the phrase eval( and let the program find it for you.

  2. Make sure you have no SQL injection vulnerabilities. Make sure you've sanitized your inputs.

  3. Make sure that any files you load where the name i specified with a PHP GET variable will not load external files. Also make sure it doesn't accept values containing ../ or anything starting with / as a value because this will allow a malicious person to run any file on your server.

Note that even if your server is secure, people will still look for vulnerabilities. If you're confident in your server's security, don't worry about it.
