EMAIL, SPAM and PHISHING
E-Mail - While
we all get infected from time to time (even systems that travel in the best
circles do...) there are some pretty basic steps to minimize the risk. As a
general rule don't open attachments unless you know who sent it and in some
cases even then its questionable as some contain viruses and others contain not
a virus but a virus hoax that don't do any real damage but wastes our time and
effort nonetheless.
Next check your anti virus programme to make sure its'
e-mail scanner is turned on. Frequently its off, especially if you are on a dial
up connection because it sometimes causes headaches when downloading your mail
and your email programme times out. That means it gets turned off. The problem
is, sometimes it doesn't get turned back on. If you decide that you DO want
to open the attachment labeled "Aunt Martha's Birthday then make a copy
of the file and manually run your virus check on it first.
Spam -
Meanwhile, one of the most annoying aspects of email may well be
the increasing number of unwanted messages you get every day. This problem
is close to epidemic with even home users facing the daunting prospect of hours
of work wading
through dozens or even hundreds of spam a day. In the corporate world its even
worse with some estimates suggesting the problem cost 50 billion
dollars globally back in 2005 and the situation doesn't seem to be improving
much. For interest sake, Canada's total was somewhere around 1.6 billion and in
the U.S. it was close to 17. The bottom line here is that not only is spam
annoying but its expensive too, especially if you are in business.
So what do we do?
Well there are some
fairly effective tools for minimizing (you'll never actually eliminate them) the
number of messages that make their way to your inbox. One of the simplest won't
cost you a cent.
Set up a 'utility' email
account. One that you can use when you get to those web-pages and services that
simply won't work unless you have a working email account. There are lots of
them, Windows Live (Hotmail), Google (Gmail), Yahoo, and AOL (AIM) to name just
a few. The idea here is that if your email address finds its way to the spammers
(and it will) at least you can filter out the junk without cluttering up your
system or your email client (Outlook, Outlook Express, Thunderbird, et al). That
leaves your regular email address (usually courtesy of your internet provider)
pretty much spam free as long as you only give it to people you trust.
Then there are a variety
of so called spam filters, eliminators and killers. Your internet provider
almost certainly uses one but sometimes its too effective and can send
legitimate messages into the "Junk Mail" folder for future deletion. Remember,
it doesn't have a copy of your address book and can't always tell the difference
between Aunt Martha's message and the latest ad for cheap prescriptions, knock
off watches or announcements you've won a non-existent lottery somewhere
in Europe. So that means there's usually some work to do at the local
level.
You can do that with a
utility designed to catch the spammers when they do manage to get through. A
search for spam utilities reveals dozens of choices, some free, some paid. These
include Spamfighter, Mailwasher, Spamcatcher and others. We've looked at some of
them but which ones are best, we'll leave up to you. That said though, the ones
mentioned earlier are the most popular and you'll find links to them on our
security tools page. (See the link below)
Finally, no matter which tool you use
make sure you have the latest version to ensure the most effective protection
and remember they have to be trained and except for some well known spam which
is automatically deleted, you'll still have to go through the motions with some
messages. The plus here though, is that you'll only have to do it once.
Phishing -
This is a
specialized type of spam that in a word is outright fraud. The messages
are designed to trick you into revealing confidential information
including usernames, passwords, credit card information to an unknown
3rd party. Most common are messages that pretend to be from legitimate
institutions like banks, trust companies and other institutions such as
retailers, Ebay, AOL or Paypal.
These attempts to
steal your information frequently come in the form of a request to
verify usernames, account numbers and/or passwords and usually include a
threat to close or suspend your account if you don't comply.
What's important
to remember is that no reputable company will ask you for such
information and have elaborate safeguards in place to make sure that
your personal data isn't revealed to anyone, even the employees of that
particular bank or company.
If you
happen to get one of these requests ignore it and delete the message
without opening it. We also suggest that you report the attempt to
organizations like
www.phonebusters.com
in Canada
or
reportphising@antiphishing.org and
spam@uce.gov in the United States.
