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)

"Hipcrime" abuse has been going on since 1996, & ther have been
numerous discussions in newgroups about it.

As I said before, it's unlikely this originated in the EU, let alone
the UK. Ergo Uk police forces wouldn't be interested IMHO.

Maybe so - I'm merely interested in the response should it be proved that it
originated in the UK.

It should
be up to Newsgoups providers to filter it,IMO.
OTOH, as you're using windows you can use Nfilter, though I don't
know how it works, or what it will kill on.


NIN seems to be doing it quite well - I'm certainly leaning toward paying
them when the free service expires!

If anyone reading this is using linux, I'm use Leafnode, which can
kill on virtually any header, including *any* part of the Path:
header. Because he's injecting (perhaps a bot telnetting) into the
path, you'll note an IP & "MISMATCH!" following. ATM I'm killing on
the ^Path:.*MISMATCH! part.

Can't use linux for work reasons unfortunately!
