Re: Discovering and Stopping Phishing/Scam Attacks

I agree that checking by referer addresses is a powerful way to detect
phishing sites, but such logs can easily be adverted?

Doesn't some anti-popup software remove referer fields?

Simple use of javascript can allow a page to fetch anything without
showing up in referer logs.

While we are on the subject, has anyone come across commercial and/or
government websites being (illegally?) mirrored?

For example, I recently came a website located on a (Asian?) hosting
provider where the content of the website was EXACTLY that of a well-known
US govt website. (It appeared that they ran the equivalent of a recursive
"wget" on the real site and hosted the files). It appeared to be several
layers deep.

Why would anyone want to do that?
