hello,

today Feb 24 between about between 10 and 11 UTC,
some hosts on 130.237.157.* where the subject of a
rather heavy ddos attack, a large part thereof against
130.237.157.246, udp ports 8812 and 8818.

Below are the most notable source ip:s. Note of course
that this is UDP, source ip:s could be faked, but hopefully
someone could detect the bot/c&c:
