    A new one. I've never seen a .PLS used as bait.

    A new one. I've never seen a .PLS used as bait.

    Interesting, a .pls file was a playlist file used in Winamp. Not sure if any other media players used it.

    Another interesting thing about that one. Although the .pls file registers as 59B in the mail header, the actual file is 0B.

    Looking at the raw message:

    Looks like this is sneaky attempt to launch a remote .php file.

    I also did not realize that the header contents could be obfuscated with UTF-8 prefixes:

    Buggers.

    Yes.. now I remember those.

    Meanwhile, while the header in my email program indicated that the .pls was 59B, it was actually 0B when I saved it.

    The email standard has really gone down the tubes as far as allowing crap like that.

    Hello Daniel Path!

    i'm wondering what's inside the pls...

    It turns out to be nothing. The "trick" was to make it look
    like there was a 59Byte attachment, when indeed there was
    nothing!

    The real vector to deliver the payload was this line:

    X-PHP-Script: crystal.net.in/mat/metoo.php for 20.52.179.36
    ^^^^^^^^^
