Claim 0:
1. A system for detecting phishing websites, comprising:
a processor configured to:
access a first website comprising a first plurality of images, wherein the first website is known to be a phishing website that is attempting to impersonate a target website;
extract the first plurality of images from the first website;
for at least a first image from the first plurality of images, determine a first hash value for the first image, wherein the first hash value comprises a first serial number uniquely identifying the first image;
determine a first overall hash value for the first website, wherein:
determining the first overall hash value comprises hashing the first hash value; and
the first overall hash value represents a first signature associated with the first website;

access a second website comprising a second plurality of images;
extract the second plurality of images from the second website;
for at least a second image from the second plurality of images, determine a second hash value for the second image, wherein the second hash value comprises a second serial number uniquely identifying the second image;
determine a second overall hash value for the second website, wherein:
determining the second overall hash value comprises hashing the second hash value; and
the second overall hash value represents a second signature associated with the second website;

compare the second overall hash value with the first overall hash value;
determine whether the second overall hash value corresponds to the first overall hash value;
in response to determining that the second overall hash value corresponds to the first overall hash value, determine that the second website is associated with the phishing website; and

a memory, operably coupled with the processor, and operable to store the first plurality of images and the second plurality of images.
