freead.name / mybar.us / toolbarcom.org / adsnet.biz

A slightly novel attack, found injected into a Javascript library and using freshly-registered domains. The attack uses obfuscated Javascript to send visitors to one of the following domains: myads.name, adsnet.biz, toolbarcom.org, mybar.us, freead.name, and to the front of this is appended a subdomain of vagi., vain., vale., vars., vary., vasa., vaut., vavs., viny., viol., vrow., vugs., vuln.

Despite all the combinations (a list is at the bottom of the post if you want to paste it in somewhere), there are only a small number of IP addresses involved:

66.221.212.92
66.221.212.94
66.221.212.96
66.221.212.98
66.221.212.99
69.13.73.203
69.13.73.205
69.13.73.248
69.13.73.250
69.13.154.250
69.13.154.251

All of those IPs belong to C I Host, some seem to have legitimate sites hosted on them.

One one domain (mybar.us) is not anonymised:

Registrar URL (registration services):       www.publicdomainregistry.com
Domain Status:                               clientTransferProhibited
Registrant ID:                               DI_11638984

Registrant Application Purpose:              P1

Although the address and phone number are no doubt fake, the email address of dday.rabbit@gmail.com is known.

The next hop uses a subdomain of a legitimate domain registered at GoDaddy that appears to have been phished: out.outdoorkitchendistributors.com - this site is hosted on 94.75.243.31.. it's just worth pausing to note that the legitimate domain specchart.com also appears to have been hijacked via a GoDaddy phish and moved to this server.

The endpoint is a Java exploit on a server at 79.135.152.194 belonging to microlines.lv (AS2588 / 79.135.128.0/19) which appears to be a pretty evil network. How the hell they got a /19 is a mystery when I can't see any verifiably legitimate sites.
