1. What is alt.privacy.spyware?
---
alt.privacy.spyware is an unmoderated newsgroup for the discussion of
internet privacy and spyware issues. This newsgroup was formed in
April of 2000.
--------------------------------------------------------------------------------
2. Who can post here?
---
alt.privacy.spyware is open to anyone who wishes to post, provided
they remain on-topic and observe established standards of netiquette.
Please note that this is a *discussion* group. Unsolicited commercial
posts, also known as spam, are not welcome and will be reported to the
offender's ISP.
--------------------------------------------------------------------------------
3. What is spyware?
---
Spyware refers to any software capable of collecting or reporting
information that might compromise your privacy.
--------------------------------------------------------------------------------
4. Can you give me some more details on the types of spyware that
exist?
---
Spyware can be found in many forms, such as an application program,
installation utility, ActiveX control, Browser Helper Object,
"cookies", (Java)script, Java applet, the HTML code found on some web
sites, or any combination of the above. In short, ANY form of
executable code and/or user-to-host data exchange can potentially be
used to implement "spyware" functionality.
Some of the more common types of spyware (but by no means a complete
list) are:
a. Keyloggers: Small programs which run silently in the background,
recording every key-press and mouse-click. The data can either be
recorded to a log which, when later "played back", will then provide a
complete step-by-step record of exactly what the user did on the
computer, or it can be sent via a network connection to another
computer where the usage of the primary system can be monitored
directly. Although widely considered to be blatant "trojan horse"
programs, keyloggers and similar utilities are also often marketed
under the guise of "parental control tools" in an attempt to
legitimize their functionality.
b. Ad trackers: Programs, scripts, etc., which attempt to collect data
on who and/or how often a given ad has been viewed, and/or "clicked
on," thus indicating a specific interest in that product or service.
Ad trackers can be as benign as simple statistical counters, or as
insidious as full-blown "E-pending" -i.e. the correlation of your
personal data (name, street address, e-mail address, age, gender,
income, credit history, etc.) with precisely which ads you have viewed
and/or clicked on, when, and from what source.
c. Usage trackers: Programs, scripts, etc., which attempt to collect
data on the usage of a specific program or function (for example,
tracking which .MP3 files you download with file-sharing programs like
KaZaa; or your usage of a particular application program on a
particular machine, such as is done by such DRM tools as C-Dilla). In
most cases, the collected data is either sent to a third party
(generally without the user's fully informed consent or knowledge) to
be used later for any of a wide variety of purposes, and/or used
directly to determine or alter the functionality of the host
application program.
--------------------------------------------------------------------------------
5. How is spyware different from, or similar to, adware?
---
The term "adware" is sometimes used to describe a class of
spyware.However, the terms are NOT interchangeable. Some spyware is
also adware; but some (cf. keyloggers and usage trackers, above) is
not. Similarly, any given example of adware may or may not also be
spyware, depending on how it operates. In its purest and simplest
form, the term "adware" only denotes applications which are in some
way supported by advertising (typically, as you use the program, part
of your screen is used to display one or more advertisements). If,and
ONLY if, the application also engages in some sort of data
logging/reporting (such as by "phoning home", i.e., reporting
information or otherwise making information available to a third party
such as the vendor or advertiser, usually via a surreptitious network
connection) can it rightly be called "spyware".
See Q15 below for a more detailed discussion; but in short, to be
considered acceptable, adware MUST be implemented in such a way as to
ensure the true consent of the user/owner AND not impinge on the
user's/owner's security and/or privacy.
--------------------------------------------------------------------------------
6. Why/How is spyware a problem?
---
Even in its least objectionable form, spyware exploits web users for
someone's financial or informational profit. The installation of
unsolicited commercial software is generally done in a sneaky,
misleading or unannounced manner. This compromises the security and
privacy of affected users,usually without their knowledge or consent.
(Also see Q15, below)
Many varieties of spyware will create unnecessary additional demands
on the victim's memory and bandwidth resources, resulting in reduced
computer performance. Generally speaking, the older or less powerful
one's system, the greater the performance degradation one can expect
to see as a result of spyware infections.
How significant these additional demands will be vis-a-vis any given
system will vary on a case-by-case basis; but, in general, even
minimal-impact spyware can represent a noticeable additional load. In
some cases, the basic functionality of the infected system is severely
impacted. The user may no longer have a choice of desktop items,
browser toolbars, web browser home page, or of which applications may
be used for what task.
In the more extreme instances, trojans and other types of spyware can
do serious damage: They can gather information about e-mail addresses
and use an e-mail application's address book in order to propagate.
Passwords, financial information, and credit card numbers can be also
compromised by this type of program.
Advertising-supported software in general falls under a slightly
different category. However, it can and must be presented in such a
way as to get the true consent of the user and not impinge on security
and privacy.
Monitoring spyware, such as a keylogger, which is installed on
business machines by an employer, also falls into a different
category. The ethics of snooping by employers is a subject that
continues to receive a lot of attention and debate. However, if you
are using your employer's computer, it's a good idea to do so only for
uses authorized by your employer.
Note that the above represent a general outline of some of the
problems related to spyware, and is not an exhaustive or definitive
list of all possible issues or concerns. There can also sometimes be
mitigating circumstances where some degree of spyware-like behavior is
actually legitimate and acceptable. For example:
- Some applications have an option to turn the spyware feature off.
For example, "SuperCookies" in Windows Media Player, although WMP is
rife with other, more general, security issues.
- Some applications phone home for potentially benign reasons, such as
an auto-update.
If features like these default to "off," that's usually not a problem.
If they come up with an alert box clearly and fully disclosing all
relevant information and asking the user for permission to connect,
that's usually not a problem. If, however, their default setting is to
phone home without specific and explicit user approval, that should be
presumptively considered spyware, as the user has no way to know what
information will be actually up/downloaded, to whom, when, or why.
--------------------------------------------------------------------------------
7. Are there any posting restrictions, rules or guidelines?
---
Unless requested, do not post the URL where you suspect you obtained
your adware / spyware / malware / parasite infection. Instead, alter
the URL in some way so as to make it human-readable but NOT clickable,
such as "h**p://www.example.com". Why? Unsuspecting or inexperienced
lurkers might just click on the URL and get unwittingly hijacked. Note
that this request applies only to suspect URLs, and is not meant to
discourage the posting of information about possibly rogue web sites.
Please DO tell us about them; just do so safely.
--------------------------------------------------------------------------------
8. How reliable is the information I might get?
---
Reliability varies and depends on many factors. Just like in any other
unregulated/unmoderated forum, anyone can post their opinion, offer
their expertise, and give advice. You never know who might have what
ulterior motives, who might only have partial information, or who is a
veritable expert on the issue they choose to address. Our
recommendation is to take everything with a grain of salt and lurk for
a while, before deciding to take *anyone's* advice. Lurking will give
you an opportunity to be introduced to the regulars and to form your
own opinion about the reliability of a poster's advice.
--------------------------------------------------------------------------------
9. How can I identify, prevent and eliminate spyware in my computer?
---
There is not one fail-safe, guaranteed method of keeping a system
spyware-free. There are too many variables, such as what programs you
commonly use, what your browser of choice is, how you connect to the
internet, etc. In most cases a combination of tools will help reduce
your system's susceptibility to spyware.
Spyware applications can infect a computer in many ways. The potential
for infection while browsing is only one of them. Sometimes spyware is
clandestinely bundled with freeware or shareware programs which are
downloaded from the Internet, included in regular programs that you
buy at a retail store, might come aboard during the use of
file-sharing applications, and so on.
Uninstalling a program which carries offending lateral spyware is
usually only part of the solution. In order to clean up spyware
remnants from the original installation, you will probably need some
software, or at least some expert advice. There are various programs,
a lot of them free, which will help you do that.
The best way to check a computer for infections is to use one or more
of many "spyware sniffer" applications, and to become familiar with
basic firewall terminology. Managing block lists and Hosts files will
protect a computer against infection while browsing the Internet. Keep
in mind that not all spyware eliminator programs are entirely
legitimate. Asking for feedback in this NG will help you choose
programs which are safe.
See Appendix 1 for a list of some applications that are frequently
discussed and used in this NG. (Posting a question here should result
in considerable suggestions and comparisons by regulars.) We recommend
that you do *not* use an adware uninstaller from an adware vendor -
since it could and probably would compound your problem(s)."
Overall, remember that "an ounce of prevention is worth a pound of
cure."
--------------------------------------------------------------------------------
10. Why didn't (X anti-spyware program) find (Y spy program or file)
on my computer?
---
Because new spyware is being developed all the time, some of it
purposely designed to avoid existing spyware detectors.
--------------------------------------------------------------------------------
11. Am I being spied upon?
---
Imagine that every time you go online, a commercial internet
application verifies its registration number against a licensing
server. Is it spying on you?
Well, it depends: If all the server does is check the number against a
list and send back a go/no-go signal then it isn't spying, at least
not in the blatant, for-profit sense we usually mean in this group.
However, perhaps the server has a GUID (="Global Unique Identifier,"
your registration number) which is tied to your registration info, and
it has your IP, and it knows when you're online. Let's say you fire up
your browser, visit a website, the website sends your IP to the
licensing server, and the server returns your name and address, etc.
to the website. *Now* that internet application is spyware.
--------------------------------------------------------------------------------
12. What are third party cookies and what do they have to do with
spyware?
---
Cookies are a standard way for your browser to exchange information
with the visited site. But, there is a privacy issue with third-party
cookies: When you go to site A, which includes content from site B,
site B gets to know a little about what you are doing at site A. If
there are *many* site As --for example, if site B is a big advertising
network-- this can be used to build a profile of your web usage.
--------------------------------------------------------------------------------
13. How can I keep track of what another person in the household is
doing on a computer?
---
This is not the proper NG for this type of question. You will find
here mostly people who are very serious about the sanctity of personal
freedoms and, naturally, privacy. Most of the regulars believe that
communication, honesty and full disclosure are the greatest tools in
order to avoid ever having to ask a question like this.
--------------------------------------------------------------------------------
14. Is privacy the same as anonymity on the Internet?
---
No. Being anonymous in the Internet is not impossible, but it's very
challenging. At any rate, anonymity is not the focus of this NG.
However, the abusive behavior of spyware vendors upon the user's
presumed lack of anonymity *is* an issue.
A company derives value from something they take from you without your
knowledge or consent. That meets the standards of most people's
definition of theft.
Spyware exploits the "lack of anonymity" for profit and returns
nothing to the victim. Under normal circumstances, there is no value
derived from the tracks one would leave around the net: They are a
by-product. The corporate world has created a value/potential
profit-maker in your surfing habits that was never intended and you
did not agreed to.
--------------------------------------------------------------------------------
15. How is the issue of consent important when it comes to spyware?
---
As mentioned previously, spyware typically sneaks into a user's
computer without their explicit or informed consent. Being fully aware
that something is spyware, and choosing to install it nevertheless,
does not change the fact that it's spyware. However, since most
spyware is designed to function clandestinely, we believe that terms
like "informed" and "coerced consent" are important: I am about to
install a program. Does it contain spyware? Am I fully informed?
Informed should mean informed. Not "You should have read the EULA and
deciphered it." EULAs can be intentionally ambiguous, and
unfortunately you don't get a screen during the installation that says
"This software monitors what websites you visit, keywords you search
for, and reports it back to ____________. Do you accept this?" Chances
are that there are "phone home" violations, among others, whenever you
see operative words like "opt-in", "opt-out", and "GUID." Licensing
agreements that accompany software downloads sometimes warn the user
that a spyware program will be installed along with the requested
software, but the licensing agreements may not always be read
completely because they are often couched in obtuse, hard-to-read
legal disclaimers. A great deal of software users routinely click on
the "I agree" button of a EULA without bothering to read it very
carefully or thoroughly. Most of us feel that this click does not
truly constitute consent.
Spyware can also be an application which is installed by coerced
consent: For example, a user may be required to accept a EULA before
they can install an essential update to a program they've come to
depend on and this agreement might include consent to accept spyware.
Or, a user may have already paid for an application only to find out
too late for a refund that they have "explicitly agreed" to the
installation of spyware.
--------------------------------------------------------------------------------
16. How can I be spyware-free without all this hassle?
---
Using an open-source operating system and strictly open-source
applications downloaded from reliable sources will minimize the risk.
However, as open-source becomes more popular, it seems inevitable that
there will be spyware which targets it. Some source code is difficult
to comprehend and could mask spyware. Also, there is much freeware
that is safe. Od course, checking with others before
downloading/installing is sensible advice.
--------------------------------------------------------------------------------
17. Do different types of programs exhibit different degrees of
vulnerability to spyware?
---
As mentioned in a previous question, the spyware "machine" mutates and
evolves based on market conditions. The primary concern of a spyware
manufacturer is volume of users. The more people who use a certain
program, or a certain version of a program, the greater the chances
are that it has become a more attractive target for spyware.
