Re: Google "Unusual traffic from your computer network" notification

We had a customer with this problem. They started with the assumption that
it was malware on the user network. After several days of hunting, they
abandoned that idea and tapped a different segment with Palo Alto (could
probably user your Sonicwall and Snort instead...or wireshark) and found
the offending google requests from a misconfigured reverse-proxy that was
allowing the world to use it. HTH.

Anyone happen to have a short term solution that could help find the
infected computer(s) such as traffic patterns that are being sent to
Google? Also a long term solution possibly an anti-malware appliance such
as FireEye that could help protect against these types of threats that our
Sonicwall IPS cannot? We have a Snort server, but that is more reactive
than proactive and there are just too many.





Thanks,



Michael
