DNS poisoning at Google?

Wed Jun 27 04:24:26 UTC 2012

Running Apache on three Solaris webservers behind a load balancer. No MS Windows!

Not sure how malicious software could get between our load balancer and Unix servers. Thanks for the tip!

Is it possible that some malicious software is listening and injecting a redirect on the wire?  We've seen this before with a Windows machine being infected.

We have thoroughly examined our root .htaccess and httpd.conf files and are not redirecting to the problem target site. No recent changes either.

We ran some NSLOOKUPs against various public DNS servers and intermittently get results that are NOT our servers.

We believe the DNS servers used by Google's crawler have been poisoned.

Can anyone shed some light on this?
