death of usenet, film at 11 (was: Massive cancel attack report)

hi all

da spielt mal wieder jemand mit cancel-messages, diesmal in der dimension
von ca. 30000 stueck. ich habe gerade die ausfuehrung (nicht propagation) der
cancel-messages bei meinem inn disabled (mit dem flag '-C'), vielleicht genau
das, was diese leute erreichen wollen. ich suche nach einem weg, die cancels
der net-abuse-moderatoren selektiv zuzulassen, wer weiss was ?

> Over the weekend, someone using sophisticated cancel-generating software
> posted nearly 30,000 cancels forged in the name of the original posters.
> The cancels purport to be legitimate spam/advisory cancellations, but,
> it is clear that they weren't.  It appears that someone ran a program
> that simply listened into inbound Usenet on a server, and generated
> cancels for every article it saw in the groups it was listening to.  The
> cancels were labeled with "tags" indicating why they were cancelled, but
> these tags were simply labels assigned to the groups the program
> was listening to.  If it was a alt.sex group, it got "twatcancel".
> If it was a comp.* group, it got "geekcancel".
> In essence, then, in the jargon of news.admin.net-abuse.misc, a Usenet-wide
> UDP (cancel every article in usenet) was operating for a time.
> The purpose of this attack is simple:  to stir up trouble and defame the
> effort to control spam (such as the Make Money Fast plague we're
> seeing).  The purpose is clear simply because of the choice of tags - to
> maximize insult and anger.
> This isn't the first time this has happened, there was a "ellisd" cancel
> attack several months ago.  The ellisd incident wasn't quite as massive
> or indiscriminate as this one.
> The origin of this attack is a little obscure at the moment, but it is
> being actively pursued.  The initial few thousand cancels had galstar.com
> in the path, attempting to capitalize on a discussion in
> news.admin.net-abuse.misc about galstar's admins.  The remaining thousands
> were injected through UUNET's open port.
> It appears, due to some references I've seen in the relevant mailing
> lists, that these cancels were all issued from galstar (and/or a
> customer called "cottagesoft.com"), from an account paid for in cash by
> persons as yet unknown.  Either directly into galstar's NNTP server, or
> via NNTP directly to UUNET's open port.  In essence, then, someone saw
> the discussions on news.admin.net-abuse.misc and saw it as an
> opportunity to take advantage of and obtained a difficult-to-trace
> account with cottagesoft.  According to reports, the account[s] have
> been terminated, and people are still actively investigating.
> It's not as hopeless as it sounds, for the number of likely suspects
> is actually quite small.  But the evidence is thin.  At the moment.
> Therefore, I believe that galstar/cottagesoft were innocent victims
> of this attack, just the same as those cancelled.
> In attempt to reduce the damage of this attack, I am am attempting to
> repost everything that was fraudulently cancelled.  The remainder of this
> report provides some statistics of the problem, and what I've done to
> help assuage the damage.
> news.admin.net-abuse.misc has several discussions going on this event,
> which have full copies of cancels so you can see the methods the
> perpetrator attempted to use to maximize confusion.
> Total cancels on this server, indexed by "tag".  Even the tags were
> carefully selected to insult and inflame as much as possible.
