Source of attack: Russian nuclear facility?

[Bryan Willett <bryan () XLORD DUNSINANE NET>]

I created a php based gaming site: www.merchantempires.net.

An unknown person with IP addresses used by iate.obninsk.com,
is currently hacking the site.  He/she is using some method
to cheat in the game through altering the database.  I haven't
figured out if its a simple php bug or other vulnerability.

As to why someone who works for a nuclear facility would
spend their time hacking my site, I can't say.  It seems
a little alarming.

I ftped over to the origin IP and discovered that their
is a large warez collection.

Who do you contact in situations of foreign based intrusion
such as this?
