Although some may see this as responding to the attacker and
hence making it worse, I've had a look and some other uk groups
have experienced attacks recently and thought I'd post my
observations:

- They seem to start soon after 9am and end around 5pm.

- The attacker will be monitoring posts and modifies his/her bot
to get around message rules (keywords/message length/size etc)

- The from field seems to repeat so it may be possible to block
senders successfully to reduce the volume (although he/she may
add more)

- news.individual.net seems to quickly block messages on their
server so disruption is kept to a minimum

- the attack seems to last for 2/3 days, so expect more
disruption

By the looks of it if this ng 'toughs it out' the attack will
end.

p.s Does anyone know of a good filter add on for OE users?

FYI:
these are Hipcrime bots flooding the newsgroup.

It's possible the headers are forgeries.

Who is Hipcrime?

HTH.

If the flood originates in the EU, is there anything the
authorities can do?

It's hard to say *where* they are originating from, & what
authorities are you referring to?



UK Police.... (*Computer misuse act ) - not sure how it covers
spam, but this seems more of a DOS attack (in that it's making the
ng unusable for some)



Perhaps the server to which he posted (wherever that was) might know
the real IP of the sender, but that assumes the operators of said
server cared, keep a log of connections, is in a place covered by
misuse laws, etc. etc.


Again, I'm no expert but wouldn't ISPs have to keep logs in the UK?
(granted, the spammer could be anywhere in the world).
