Phishing |

Recently
I have received email from my bank/credit
Card Company, eBay & pay pal saying that
my account has possibly been compromised
and I need to confirm my details and password
in order to get continued access.
Spam email now has a new and more frightening
variant, it's called phishing and it has
been made by criminals and hackers who aim
at getting unwitting consumers to reveal
account numbers and passwords.
Usually after getting an email like the
ones mentioned above from reputable companies,
most of us would race to respond as quickly
as possible. However, in most cases you
will find that you won't be helping anyone
other then the criminal who wrote that email
and who has nothing to do with the actual
organizations.
What is Phishing?
It is when someone creates false email that
pretends to be from a bank or other authority,
but which is actually designed to collect
sensitive information such as passwords.
This process of stealing information used
for fraudulent purposes is the latest problem
to plague Internet users. It is a phenomenon
know as phishing i.e. emails 'fishing' for
important information.
Just like Spam, phishing mails are sent
to the widest possible audience so it's
not unusual to receive a message asking
you to confirm account details from an organization
you do not actually deal with. You may be
asked to fix up your eBay account when you
haven't even got one!
In addition to collecting sensitive information
many phishing messages try to install spy
ware, Trojans etc. allowing hackers to gain
backdoor entry into computers.
Types of Phishing Emails:
Some phishing emails ask for a response
by email.
Some emails include a form for collecting
details that you are told to fill out.
Some even include a link to a web site that
resembles the actual site you expect to
visit, but is actually a clone of the original
site.
Number of active phishing sites reported
in March, 2005: 2870
Number of brands hijacked by phishing campaigns:
78
Contains some form of target name in URL:
31%
Country hosting the most number of phishing
sites: United States of America

Phishing attacks can be really sophisticated.
Some time ago a flaw in Internet Explorer
allowed hackers to display a false address
while redirecting the user to an entirely
different site making it almost impossible
to distinguish a phishing attack from a
legitimate email.
Possible solutions:
New technologies can provide a better means
of countering phishers. One option being
explored by a lot of banks is the use of
a secure token, a small electronic gadget
that generates a unique password to be entered
each time a user logs onto the web site.
This would make a phishing attack useless
because without the physical possession
of a token it is impossible to access the
account. This approach is somewhat similar
to what is used at Automated Teller Machines
around the world where you need to have
both the card and the Pin number in order
to use the machine.
One option is to use a technology popularly
knows as PassMarks that effectively acts
as a second password. After entering the
user name a unique image pre selected by
the user is displayed before s/he is asked
for the password. If the proper image is
not displayed the user will come to know
that s/he is not on the authentic site.
Another option that a lot of organizations
are exploring is using text messages instead
of email messages. Text messages cost money
to send, so Spammers are less likely to
partake in the process making it easier
to distinguish between legitimate messages
and fakes.
