    odd GET s

    I was combing through my Apache logs, just checking up on things and I
    found something very odd that I've never seen before. These wierd
    accesses:

    index.php?=PHPE 9568F34-D428-11d2-A769-00AA001ACF42
    index.php?=PHPE 9568F35-D428-11d2-A769-00AA001ACF43


    I'm not sure what this is.

    This is what they do:

    The first one simply displays the Zend Optimizer logo, and the second
    one goes to my home page.

    The first one only occurs about 10 times, on the same page, from 2
    different IPs. The second occurs probably 50 times, on the same page,
    from 4 different IPs.


    Does anyone know what this is? If so, can it be useful to me, or is it
    simply a security hole.

    What does index.php do? Does it expect arguements in $_GET or $_POST
    ??? It might well be a hacking process crawling the web for php
    suffixed files and then sending some duff information to see if PHP
    would throw out an error (if it did, then I guess it might give the
    hacker something to work on).

    I can't see how youget the Zend Optimizer logo from the first link, and
    your home page on the second link. I think first time around, its
    reading it from your PCs cache - I'm not sure - I'm guessing...

    Hope that helps some,
    randelld

      The first request is a PHP "Easter Egg". In order to not show the logo, you
      need to set expose_php to off in php.ini. Someone may be trying to
      determine if your server is running PHP (for benign or malevolent reasons).
      The second request, as far as I know, is meaningless.

        I don't know the technical term for these type of strings, but they're
        completely harmless PHP control codes. They actually work on any
        webserver with expose_php enabled (see, for example,
        http://www.php.net/?=PHPE9568F36-D42...9-00AA001ACF42 ) If they
        make you nervous, though, you can set the expose_php in your php.ini
        file to Off.

        There are actually four codes that I know about (you can see their
        definitions in the php source within /ext/standard/info.h)

        ?=PHPE9568F34-D428-11d2-A769-00AA001ACF42
        Displays the PHP logo. (This provides a way for the phpinfo function
        to display a PHP logo).

        ?=PHPE9568F35-D428-11d2-A769-00AA001ACF42
        Displays the Zend logo. (Also used by phpinfo).

        ?=PHPE9568F36-D428-11d2-A769-00AA001ACF42
        Displays an "easter egg" image of a rabbit in PHP 5.0, a dog in PHP
        4.3.0, or some dude in 4.2.3

        ?=PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
        Displays the PHP development credits. (This page is linked to from phpinfo).

        I hope this helps.
