We've been using OpenDNS to block known phishing hosts. We then immediately
report the site to phishtank.org as well as Google and usually it gets
blocked within a couple of hours if enough legitimate reports are received.

I'm including a google docs link from a recent phish here to illustrate
how we handle this problem.  I expect there will be a warning about the
mischief possible with google docs inserted by our spam filter above my
message.  In that way, we can still allow the relatively rare legitimate
use of google docs to proceed.

By the way, this particular google docs link is still live this morning,
even thought I reported it to google last Friday.   If you follow the link
and submit some bogus data, you will find on the thank you page a link to
review the database.  Phishers don't often leave that option in, but it did
allow me to collect nearly 300 addresses and send out a warning to them, in
hopes they see the message before the phisher accesses their account.

  I agree that user education is the preferred method to avoid any
security incident, not just phishing. I have a question to the list members
who have seen positive effects from user awareness training. Do you have
any requirement for user awareness training, such as a required annual
training for all affiliates? If you do outreach, do you cover all
departments or select high value targets, such as finance?



I am wondering whether Oxford does any user security training? Blocking
Google docs seem like overkill, especially since they admit that the
business impact was higher than expected. But allow me to speculate here;
maybe options are limited in terms of outreach and blocking seems like a
way to limit damage, but possible also has the benefit of making users
aware that Google docs can be used as a vehicle for security incidents.
Maybe something along the lines of awareness training by impact. In our
environment, as other have mentioned already for their universities,
blocking Google docs would not work, not even for the timeframe mentioned
in the article.
