What is Spyware?
According to Microsoft
Spyware is a general term used to describe software that performs certain
behaviors such as advertising, collecting personal information, or changing the
configuration of your computer, generally without appropriately obtaining your
consent first.
Spyware is often associated with software that displays advertisements
(called adware) or software that tracks personal or sensitive information.
Let's Talk About Spyware
Why would someone write spyware?
lets say you have a web site and you want to
drive more people to that website. You go surfing on the net trying to
find out how to get more people to visit your site and you come across one of
the thousands of adds that reads something like. "1 million visitors
guaranteed to visit your site for only $29.99" You think "this is
what I've been looking for! and for that price if only 1 person buys out of the
1 million people I'll make my money back easy!"
So you click the link and you fill out the information they ask
for and you pay your $29.99!
when the seller gets your order he needs to figure out just how
he is going to get 1 million people to come visit you! How does he do
this? He writes spyware!
We have all seen spyware sites in action! Some of us simply
don't know we are seeing them!
have you ever got a pop up that opens a web site on your
computer that you didn't want to go too? (You just helped someone fulfill
his 1 million visitor order)
keep in mind that the people who buy this kind of advertising
and promote spyware are not the average business looking for more hits.
Why?
have you ever got a pop up? what's the first thing
you do? you close the popup! most of you don't even look around you
get annoyed that your being set someplace that you don't want to go and you
close the site. so the 1 million hits that were bought and paid for have
done little more then upset the visitors! This simply is not the way
you go about selling things on the net. UNLESS you
offer something that will catch the eye of a visitor quick. maybe
-
You are selling porn
-
You are a Gambling site
-
You are selling MORE spyware cures
-
You are selling a pop up blocker
-
Illegal software sales
"there are many other types of sites that use spyware to drive
traffic the above are just the ones I would put at the top of my list."
The Spyware Infection
Trick
Another way people make lots of money writing spyware is to
infect your system and then tell you that your infected and that they have
the cure. (for a price)
First they get you infected (we will talk about how in a bit)
Once your infected you will notice a few things pretty fast!
-
Your Computer will slow down
-
Internet connection will
start acting up. Oh they won't stop you from using the internet 100%
simply because they need you to stay connected so they can sell you "the
cure."
-
Within a few days you will start
getting some neat new message that tells you that you are infected and that
there is a cure.
-
In some cases your computer will
become locked and the only thing that works is the link to "the cure"
If they manage to get you to buy "the cure"
it will (in most cases) Fix your computer! Well the truth is what it does
is flag you as a "sucker" Within a few weeks (maybe days) a new
infection will hit you computer and a new cure all will be offered to you! (for
a price) and this will go on and on and on...
The other thing that spyware does is it
invites friends to join it. if you get infected with one
piece of spyware there is a great chance that it will open the ports on your
system that it needs to invite in more spyware.
We have seen computers that have had over 20,000 infected files
on them! It's kind of funny in a strange way because the spyware will
start fight itself for running time on your computer. What not funny
is that system this far infected seldom get it's speed back and they tend to
land on a technicians desk and bring a high cost to repair home with them.
Note: There are MANY other types of spyware but they are all
pretty much made to drive traffic or sell you a cure of some type.
How Do they Infect You?
Lets go with the top 5 (there are many, many others)
-
Email with links or attachments that lead to infected sites
-
Visiting infected sites
-
Downloading infected files (more on this below)
-
Security settings not set up right on your system
-
Not keeping your Microsoft OS updated
Sites that are well known for infecting computers with spyware
-
Porn sites! By far
#1 on the list.
If your an adult that wants to look at adult things I get it!
However if you are so inclined do yourself a favor and keep your local computer
repair company on speed dial! there are safe sites no question
however there are 100 infected sites for every good (none infected ones)
your playing a guessing game and it's going to bite you sooner or later.
2. Gambling
Sites
It's not playing the games that gets you most of the time.
It's the advertisements that they offer that lead to the infected sites.
3. Free
Music Sites
A piece of spyware and or a virus are in simply terms "a program
that is made to install something on your computer that does damage or sends you
to an infected site". Can you think of a better place to hide such a
program then adding it to the most popular music on the net?
4. Cheat
code sites
Why is it that a kid with spend $50.00 on a game and then go get
a cheat code that allows them to beat the game in 10 minutes anyway? Most
people that run cheat sites make there money from the ads they put on there
sites, many of these ads lead to infected sites. Other allow you do
download saved games and "add on" programs to modify your game. many
of them are infected.
5. Direct Connect
sites
Sites that allow direct connection from your computer to another
computer for the purpose of sharing files. (music, games, and web cams are the
first to come to mind)
Remember when you connect with a computer on the net you have no
idea who is on the other end of that connection. It could be a 10 year old kid
or a 100 year old adult. You also have no idea what they are running on
there computer or what is infecting there computer. When you make that
connection if they are infected chances are a well written piece of spyware will
find you and infect you. You also have no clue how many other computers
they have connected with.
So how do I Protect
Myself from Spyware?
1.)
Keep your Windows updated!
- Go to Start > Windows Update or navigate to
http://windowsupdate.microsoft.com,
and install ALL Critical security updates listed (you will need to
use Internet Explorer to do this). If you're running Windows XP, that of
course includes Service Pack 3 (SP3)!
- It's important always to keep current with the latest security fixes
from Microsoft. This can patch many of the security holes through which
attackers can infect your computer.
Please either enable Automatic Updates
under Start > Control Panel > Automatic Updates, or get into the habit of
checking for Windows updates regularly.
2.)
Watch what you download!
- Many "freeware" programs come with an enormous amount of bundled spyware
that will slow down your system, spawn pop-up advertisements, or just plain
crash your browser or even Windows itself.
- Peer-to-peer (P2P) programs like Kazaa, BearShare, Grokster, Imesh, and
others are amongst the most notorious. If you insist on using P2P software,
please read
this article
written by Mike Healan of SpywareInfo. It is an updated and comprehensive
article about which P2P programs are "safe" to use. Another good reference
is
here.
- Note also that even if the P2P software you are using is "clean", a
large percentage of the files served on the P2P network are likely to be
infected. Do not open any files without being certain of what they are!
3.)
Avoid questionable web sites!
- Many disreputable sites will attempt to install malware on your system
through "drive-by" exploits just by visiting the site in your browser.
Lyrics sites, free software sites (especially ones that target young
children), cracked software sites, and pornography sites are some of the
worst offenders.
- Most of these drive-by attempts will be thwarted if you keep your
Windows updated and your internet browser secured (see below). Nevertheless,
it is very important only to
visit web sites that are trustworthy and reputable.
- In addition, never give out personal information of any sort online. And
never click "OK" to a pop-up unless it is signed by a reputable company and
you know what it is!
- Get a Router! D-link routers have a great little firewall built
into them that will deny many attacks before they get to your computer.
If you have a high Speed internet connection and don't have a hardware
firewall installed your taking a chance that you don't want to take.
(Microsoft firewall is NOT a hardware router)
- For more general information see the first section, "Educate yourself
and be smart about where you visit and what you click on", in
this tutorial
by Grinler of BleepingComputer.
Must-Have Software
*NOTE*: Please
only run one anti-virus program and one firewall on your system. Running more
than one of these at a time can cause system crashes and/or conflicts with each
other. The rest of the following programs can be run simultaneously and will
work together in layers to protect your computer.
4.)
Antivirus
- I will tell you that I am NOT
a fan of most of the free anti virus programs that are out there. I
recommend using Internet Security
by TREND MICRO over any other product on the
market. It has served me and my clients very well over the last 6
years. It is the # 3 best selling anti virus on the market. Thus many
of the spyware people that are writing programs that attack the top 2
sellers over look it.
- It's a good idea to set your antivirus to receive automatic updates so
you are always as fully protected as possible from the newest threats.
5.)
Internet Browser
- Many malware infections install themselves by exploiting security holes
in Microsoft Internet Explorer. It is strongly suggested that you consider
using an alternate browser.
- Both
Mozilla Firefox
and
Opera
are next-generation browsers that are more secure and faster than Internet
Explorer, immune to most known browser hijackers, and outfitted with
built-in pop-up blockers and other useful accessories.
6.)
Firewall
- It is critical that you use a firewall to protect your computer from
hackers. We don't recommend the firewall that comes built into Windows. It
doesn't block everything that may try to get in, it doesn't block anything
at all outbound, and the entire firewall is written to the registry. Since
most malware accesses the registry and can disable the Windows firewall,
it's preferable to install one of these excellent third party solutions. I
know that this is repeating myself but D-LINK
routers have a great Firewall built in and I seldom use anything else
7.)
Install Javacool's
SpywareBlaster
- This excellent program blocks installation of many known malicious
ActiveX objects. Run the program, download the latest updates, "Enable
All Protection" and you're done. Although it won't protect you from
every form of spyware known to man, it is a very potent extra layer of
protection.
- Don't forget to check for updates every week or so. Also see
this tutorial
by Grinler.
8.)
HOSTS file and IE-SPYAD
- Another good program is
MVPS HOSTS.
This little program packs a powerful punch as it blocks ads, banners, 3rd
party Cookies, 3rd party page counters, web bugs, and many hijackers.
- For information on how to download and install, please read
this
tutorial
by WinHelp2002.
-
IE-SPYAD
puts over 5000 malicious sites in your restricted zone, so you'll be
protected when you visit innocent-looking sites that aren't actually
innocent at all. See
this
tutorial
by Grinler.
Other Cleaning / Protection
Software
9.)
Ad-Aware and Spybot
- If you do not already have it,
Lavasoft's Ad-Aware
is a must-have free scanner. See
this
topic
for instructions on how to configure and run Ad-Aware.
-
Spybot Search & Destroy is another
must-have free scanner. See
this
topic
for instructions on how to run a scan with Spybot.
- Spybot has an "Immunize" feature which works roughly the same way
as SpywareBlaster above.
- Another feature within Spybot is the
TeaTimer
option. TeaTimer detects when known malicious processes try to start and
terminates them. It also detects when something wants to change critical
registry keys and prompts you to allow this or not. See
this tutorial
by Grinler for more information.
10.)
(Ewido) AVG Anti-Spyware
- An outstanding all-purpose anti-malware scanner and cleaner is
AVG Anti-Spyware.
Although this is commercial software, the 30-day trial version will continue
to work after the trial period expires in "free mode", with automatic
updates and real-time protection disabled. See
this topic
for instructions on how to run a scan with AVG Anti-Spyware.
11.)
Windows Defender
- Microsoft now offers their own free malicious software blocking and
removal tool,
"Windows Defender"
(Not compatible with Windows 98 and ME.) It also features real-time
protection.
12.)
Lock down ActiveX in Internet
Explorer
- Even if you plan to use an alternate browser, you will have to use
Internet Explorer for tasks like updating Windows or visiting any other site
that requires ActiveX. Also, since Internet Explorer is integrated into the
Windows core, keeping it locked down is very important.
Open IE and go to Internet Options >
Security >
Internet, then press "Default Level",
then OK.
- Now press "Custom Level."
In the ActiveX section, set the first two options ("Download signed and
unsigned ActiveX controls) to "Prompt",
and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".
- Now you will be asked whether you want ActiveX objects to be executed
and whether you want software to be installed. Sites that you know for sure
are above suspicion can be moved to the Trusted Zone in Internet Option >
Security.
- So why is ActiveX so dangerous that you have to increase the security
for it? When your browser runs an ActiveX control, it is running an
executable program, no different from double-clicking an exe file on your
hard drive. Would you run just any file downloaded off a web site without
knowing what it is and what it does?
