Experiencing computer trouble? Any crashes lately?
It could be Gremlins. No seriously, it could! And the one
we're talking about today comes with a name and a reputation
that makes spam seem nothing more than a minor headache. We're
talking… SPYWARE. Sounds a little spooky, doesn't it?
Though it can come to us maliciously, it's usually a bit more
subtle and hard to detect. Maybe that's why it also uses
something a bit more innocuous and pleasant sounding such as
the word, cookies. Before you start smelling the lovin' from
the oven, let's take a look at what we're talking about. For
certain, these are not the cookies you remember from home.
Cookies
are small packets of information placed on your computer by
web sites you visit. They may contain and provide identifying
information about you to the web sites that place them on your
computer, along with any other information the site wants to
retain about your visit. To an extent, cookies allow us to
traverse the internet with greater convenience and speed as it
personalizes the visit. Passwords, preferences and personal
information are stored and sent from your computer to the web
site.
How are
cookies used?
Typically, when shopping online, a
product is selected and placed in the cart. Before completing
the sale, the user may decide to price comparison shop at
other sites. The online store can choose to save information
about the products in the cart on the user's computer, so when
they access the site later, they can finish the sale if they
choose.
In the
next example of how cookies are used, keep in mind this is
where we lose consensus about the innocuous cookie, because
the information gained about our preferences can be used for
online targeting ads. It's rationalized that web sites must
generate revenue to pay for its overhead expenses in order to
continue to service users. Additionally, untargeted and
obtrusive ad campaigns don't carry the same money making
umph as targeted and directed campaigns. Though they
may or may not know my name and address, they certainly know
from watching where I've been and what I buy that I like Ray
Charles--and they profit from this information. Garnering this
information without my expressed permission is spyware.
John C.
Dvorak, PC Computing, reported in his October 11, 2004 article that the House of
Representatives had just passed the Internet Spyware
Prevention Act. The proposed federal law will eventually make
it illegal for companies to install spyware of any kind - in
all its forms. I agree; it's convenient when my password pops
up when accessing a site, but as Mr. Dvorak also underscores
in his article, "Whose idea was this anyway?" A better
solution exists. According to Ari Schwartz, Associate Director
of the Center for Democracy and Technology, a privacy-advocacy
group, "failure to properly address spyware and users will not
want to use the Internet for commerce, for government
services, for interaction with other people. We'll lose the
great potential of the Internet."
What is
Spyware?
Steve Gibson, Gibson Research
Company, is to Spyware developers what Ralph Nader is to
those that profit from polluting the environment. Steve's
definition of spyware is the best I've read by far: "Spyware
is any software which employs a user's Internet connection in
the background (the so-called "backchannel") without their
knowledge or explicit permission. Silent background use of an
Internet "backchannel" connection must be preceded by a
complete and truthful disclosure of proposed backchannel
usage, followed by the receipt of explicit, informed, consent
for such use. Any software communicating across the Internet
absent these elements is guilty of information theft and is
properly and rightfully termed: Spyware." Here's a few more
examples of awful Gremlin names: Adware, Spies, Cookies, Key
Loggers, Parasites, Trojans, Worms, Dialers, Browser Hi-jacks,
etc.
Symptoms of computers infected by Spyware
America Online and the National Cyber Security
Alliance conducted a study where spyware was found on 80
percent of participants' computers. According to Tim Lordan,
staff director of the Internet Education Foundation, "Often,
you don't just have one. You might have a half-dozen or even a
dozen that can bring your computer to a screeching halt."
Since Earthlink began offering subscribers free spyware scans,
they found in the first 3 months of the offer, "scans of more
than one million hard drives found an average of 28 spyware
installations per PC." The most common type of spyware is
known as adware and its main goal is to generate annoying
pop-up ads. Another malicious type actually hijacks your
browser setting and directs it to dubious search engines from
which these developers derive commissions.
Symptoms:
--Endless pop up
windows
--Browser is redirected to unwanted web
sites
--Unexpected toolbars in your web browser
--New
icons in your task tray
--The tab key may fail to work
--Random Windows error messages appear
--Computer
crashes frequently
--System seems slow and sluggish to
simple tasks
This
general list was taken from http://www.spywareonline.org/ and provides
you an idea of what to look for the next time you feel
Gremlins have invaded. Before you take an ax to your CPU
consider: spyware programs are often poorly written and
contain bugs and are ever hungry for more of your systems'
resources. So, what to do?
Protect
yourself and be aware of the freebies
It holds true
after all, there's no such thing as a free lunch. Spyware
programs are creative and often look like our system files.
The most common ways to pick up adware/spyware is to download
file sharing software, screen savers, games, music and other
free programs. Honestly, how many of you out there actually
read the End User License Agreement and how many of you just
click through it? Now you'll be encouraged to read carefully
for certain. Otherwise, you may actually grant permission for
the gremlin to enter by accepting the agreement that contains
third party software may be installed wording. Be aware and
suspicious anytime anything prompts you to download. Be sure
to keep your antivirus updates current and ensure the program
is running before you traverse through the Internet. And
regularly update and run your spyware scans.
Gremlin
search and destroy
Steve Gibson highly recommends Lavasoft who
developed a freeware spy removal utility as well as offers a
fully featured version by the name of Ad-aware. This was
personally recommended to me a long time ago by my ISP's
expert tech help at bluetie.com. There are tons of free
spyware programs out there now--be careful which ones you
choose--check them out first. Blue Tie's excellent customer
assistance led me to the tucows.com site for the free
download. It rates 4 cows! Here's the link to Lavasoft's
free Ad-aware removal utility: http://www.tucows.com/preview/236049.html I
know I said free and you should be aware, but
tucows.com enables you to see who the freeware manufacturer is
and provides a link to their site. You are your first line of
defense. Check out the company and decide for yourself the
level of risk you're willing to accept for the benefit of
freeware and who it is you're willing to trust and at what
cost. Ethical and business is not necessarily an
oxymoron.
The
spyware developers sure have created quite a market for clean
and sweep programs. They know you're filtering and you can bet
they're staying updated on the latest filters and changing
their code accordingly. We have no choice but to remain
vigilant until the Federal Laws catch up with technology. Even
when change finally occurs, we are still our own first line of
defense and nothing can take the place of vigilance, staying
on top of the issues, good judgment and common sense.
