Phishing
Techniques
Recent attempts
by Phishers target the customers of online payment services and banks. U.S. taxpayers received
Emails from scammers who appear as though they were from the
Internal Revenue Service, as a result these phishing attempts
have exposed
sensitive data. This allows phishers to possibly know which
banks or services customers/potential victims use. Senior
executives and high ranking individuals within the businesses have been
a recent target. The term "whaling" has been coined to describe these
kind of attacks.
Social networking websites (e.g. Myspace, Facebook) and other
community-based sites are a target of phishing because the personal
details in these websites can be used in identity theft. The success
rate of Phishing attempts on these sites are highly staggering.
Link manipulation
Phishing is mostly used to decieve users, it's designed to create links
recieved online (usually via email) seem as though they were from an
established, trustworthy company when in reality it is just a spoof for
the website it leads to.
These Phishing links take the form of misspelled URLS and also
subdomains.
Examples of
such links are http://VictimsBank.example.com/, this will
appear as if the link were normal and a part of the real website of
your back, but in truth directs to the phisher's domain which
in
the example is
" VictimsBank".
Another trick Phishers use is to make a link in an anchor text seem
valid, but the link actually fowards to the Phishers' website.
These can be very hard to spot with the untrained eye, which is why
websites such as Paypal.com recommends that you manually type-in their
website instead of following email links, which could be from phishers
who point a link to their domains. Such Fraud
links continue to populate the internet
Phone
phishing (aka Vishing)
Phishers are so deseprate to find unsuspecting
people,
so much so that they find means and ways of doing this without even
using websites. For example, a potential victim gets a message that is
"supposedly" from a bank, telling him or her to dial a phone number
pertaining to problems with their bank accounts. When the victim dials
in the phone number -- which is the phishers' number -- it
asks
for them to type in their PIN numbers, which results in victim exposing
such sensitive information to a scammer.
Other techniques used by Phishers include Filter evasion and forgery of Websites.
Filter evasion occurs
when phishers
try to use images instead of text in order to see if they can
manipulate anti-phishing filters which usually catch text used
in phishing.
In Website Forgery
victim is
deceived into visitng a fake website, few phishing scams employ the use
of JacaScript to change the address bar by inserting an image of a
legitimate URL atop the address bar. Or opening a new legitimate
address bar after closing the original. Scammers may even manipulate
holes inside a trusted site and use it against customers, "cross-site
scripting attacks" as it is called, directs users' to sign into their
accounts (bank or services) with everything appearing legitimate, when
in fact the link is created for one purpose: attack victims.
