Injection attacks: adbnr.ru

adbnr.ru seems to be the latest domain to be used by the bad guys in this current round of injection attacks. The injected code to look for is adbnr.ru/ads.js (obviously don't visit that page unless you know what you are doing). That leads to a heavily obfuscated piece of Javascript which I haven't dissected yet.. but really there is no doubt that it is going to try to do something very bad to your computer!

Both the telephone number and email address have been connected with malware attacks before.

Looks like it is using a fast flux botnet for hosting, but blocking adbnr.ru should be effective.
