Are You Being Watched?
If your computer is connected to a network (this includes the Internet)
you should be very concerned about security. You should be especially
concerned if you use your computer for accessing a bank account,
placing orders online, or if you have sensitive information on your
hard drive.
In recent months spyware
and trojans
have hit epidemic proportions...And now we are adding root
kits to the mix...Not only from hackers and virus writers...But
Sony
no less...
Some of my most frequently asked questions are: "Why do people
create these programs and how do I get this malware on my computer
to start with?" Let's start with why. In general there are
three main reasons:
- Remote control of your computer: These programs use your
computer to perform attacks on other systems, send spam, etc.
The hacker has complete anonymity, he is using your computer to
do the dirty work. I'll bet you didn't know that your computer
is part of a major child porn distribution network. The M.I.B.'s
(men in black) will knock on your door, not his.
- Advertising: The sole purpose is to blast you with unwanted
ads and pop-ups. Each one of those pop-ups is a hit on some company's
web site Marketers will guarantee to triple the traffic on your
web site for a small fee. They don't tell you that your site is
a pop-up that most of us hate.
- Tracking: Companies want to know where you are browsing...For
example, would any of you like a list of everyone in the county
that accessed the web to look for a new house in the last month?
These same trackers can be used to record anything that happens
on your computer: passwords, account numbers, email...every keystroke.
Now that we know why...how do these monsters get on our systems:
It is critically important that your system and network be setup
by a competent computer tech...The default install of Windows XP
is ridiculous, and the vendors aren't helping the problem, Dell
systems come with MyWay search installed. Any program (updater,
toolbar, chat, etc.) that talks to the network is a potential open
door to hackers.
- Laptops and wireless: Is you laptop a disaster looking
for a place to happen? Read
this.
- iPods and music downloads: Do you, one of your kids,
or someone on your network at work have an ipod? Read
this.
- Program security holes: Keep your programs updated with
the latest patches...Know what programs are accessing the network.
A good firewall will help in this area. Once infected these programs
are very difficult, if not impossible to remove. Many of these
programs can hide from the best adware and virus scanners. The
best defense against spyware and other unwanted software is not
to download it in the first place. Here are a few helpful tips
that can protect you from downloading software you don't want:
- Only download programs from websites you trust. If you're
not sure whether to trust a program you are considering downloading,
ask a knowledgeable friend or enter the name of the program
into your favorite search engine to see if anyone else has
reported that it contains spyware.
- Read all security warnings, license agreements, and privacy
statements associated with any software you download.
- Never click "agree" or "OK" to close
a window. Instead, click the red "x" in the corner
of the window or press the Alt + F4 buttons on your keyboard
to close a window.
- Be wary of popular "free" music and movie file-sharing
programs, chat programs, add-on toolbars, and be sure you
clearly understand all of the software packaged with those
programs.
- Operating
system security holes: There is little you can do about
this problem other than to be sure to stay updated with the latest
security patches, and to have a competent computer tech set up
your system...The default install on most brand new systems is
ridiculous. If you want to give it a shot yourself, here's
a good place to start. Keep in mind that what is going on
inside your computer, behind all the pretty icons, is bordering
the complexity of a living organism.
Sometimes the only way to tell if your computer is infected is
by erratic behavior and slowness of the machine in general. Here
are a few programs that will help if you want to try to check your
computer yourself.
Adaware:
A good freeware spyware detection program.
Cleanup:
A good freeware program to clean up the temp files on your computer.
Hijack
This: A good freeware program that gives you a startup list
from your computer. Be careful with this program, you can make system
changes with it. Do not make any adjustments that you do not completely
understand.
Rootkitrevealer:
A good freeware program for detecting some root kits. Do not make
any adjustments that you do not completely understand.
When given a choice between a computer that is secure and one that
is not, nearly everyone will say they would prefer the secure computer,
all else being equal. But things are not equal. Despite clients'
cries for more secure computers, when it comes to writing the check,
security and system administration often gets the short end of the
stick. When making the decision about setting up your system, remember
the old saying, "You never have the time (or money) to do it
right, but you always have the time (and money) to do it over."
