[Dshield] interesting little snippet

It looks to me like a piece of PHP code to open a remote file on an IP
assigned to fh-aalen.de in read mode as a binary file - even though it has a
".txt" extension.

I googled for "muschi.txt" and found 12 hits - all in Germany.  They all
appear to be p0rn-related, and when I opened up one of them (on a
sacrificial system) it fired off about a gazillion p0rn pop-ups.

Looking up the source IP, I found the following at RIPE:

inetnum: -
descr:        Educational institution connected to SEKTORNET
descr:        the Router Network for the Ministery of Education in Denmark

My guess from all of this is that some skoolkiddie was looking for an open
proxy to use for viewing p0rn, maybe.

Something rotten in the state of Denmark?
