Re: Blocking phishing URL's

While not the most efficient way to do it, it has worked for large majority of the phishing we get.  I create a zone in 
DNS, and set the hostnames in the URL to point to 127.0.0.1.  It won't work for stuff housed at say Google Docs,  but 
it's been pretty effective here.

A downside to this (or any method at the edge), is there is no way to block them when someone accesses their mail 
remotely (ie web based mail)

Subject: [SECURITY] Blocking phishing URL's

Greetings!

I've been asked to investigate what other institutions are doing to block access to URL's at the edge (i.e. block 
connections when people click on a URL, despite virtual hosting or fastflux DNS).

Feel free to respond privately.  Thanks.

Best,
Cathy
