[nsp-sec] Packet love to AS9192

	Good day,

	AS9192 has been getting lots of love in the form of large UDP packets 
(above 1 KB) to 194.149.73.156 and 194.149.73.80, both machines from IRC 
Hispano.

	As a mitigation measure, they have withdrawn the entire /24 from BGP.

	Unfortunately their netflow is broken so they can't tell any more 
details. The attack began a few hours ago.

	If your flows show something large towards those IPs now (i.e., more 
than normal DNS resolution attempts), you have most likely identified a 
bot. Any intel you can share will be much appreciated.

	More info if and when it comes.
