[Full-Disclosure] Someone hacked anti-spam database. World bouncing email

[Michael Scheidell <scheidell@secnap.net>]

Some time before 11:30 AM Eastern time, the anti-spam database
socks.relays.osirusoft.com run by osirusoft.com seems to have been hacked.

Possibly thousands of innocent system admins then found that email their
users sent out was being bounced by uses of this database, even though
they never spammed, and never ran a 'socks' proxy, and were not in the
dialup database (the FTC uses this to protect their 'uce@ftc.gov'
address!)

I found bogus responses back on innocent ip addresses that seems to have
been 'stuffed' into osirusoft.com socks.relays RBL., or an * wildcard has
replaced the legit database.

(including the netscreen list at qorbit.net)

The TXT record that responds is: Please stop using relays.osirusoft.com

Looking at news:news.admin.net-abuse.email I see several warning about
using relays.osirusoft.com

This is not surprising, since they run the (popular or un-popular)
anti-spam database 'spews' and have been under DDOS and hacker attack for
months.

What appears to have happened, is maybe dns cache poising, DNS hyjacking,
or maybe someone directly compromised the dns server and edited the
database (or one of their secondaries) or, aliens in green suits decided
to block all email to anyone using the socks, dialups (and maybe spews)
databases?

Anyone have any more information on this?
