Caught on the Net: spying gets easier
Beware the messages you leave on the Net.
Your spouse, employer or kids may be watching.
by Julian Sher, jsher@journalism.com
The unwitting civil servant in Nova Scotia was delighted to discover
he could use his office computer to send personal messages over
the Internet to a Christian Bible chat group. He bared his soul
in more than 250 written postings. He talked about his faith in
God and Jesus and how the Ten Commandments are a sign of mankind's
need for help.
What he didn't know was that others besides God and his fellow
Christians were watching. Every posting could be easily traced according
to its government return address and read by CBC journalists on
an Internet training course in Halifax. The reporters were given
a simple exercise: Track how provincial employees were using office
equipment and time to carry on personal business on the Internet's
public billboards and chat forums.
"I was appalled", said the man, who asked to remain anonymous,
after learning his remarks had been meticulously catalogued on a
highly popular Web site called DejaNews. "I had no idea anything
like that was possible."
Call it the 11th Commandment: Watch what you say on the Internet.
Controversy over electronic privacy is nothing new. Seized electronic
mail has figured prominently in sensational investigations ranging
from the U.S. Iran-contra scandal to the current antitrust suit
against software giant Microsoft Corp. Many office workers by now
know that ostensibly private messages sent over corporate computers
are considered company property, and that those messages are routinely
backed up and stored to guard against data loss in the event of
a network failure.
What makes the above case different is the ease with which people
can now locate and read each other's public messages. Although the
E-mail postings in question were not strictly private (intended,
as they were, to be read by like-minded others in the Christian
chat group), it's now possible for anyone with an Internet connection
to pore over those public postings - indeed, over someone's entire
chat history - with the click of a button. That's because companies
with powerful Net-searching computers, most notably DejaNews and
the search service AltaVista, have begun harvesting bulletin-board
and chat-group messages and indexing them on their popular, advertiser-supported
Web sites. Simply visit the free site DejaNews, type in someone's
E-mail address and, instantly, you're presented with every public
remark or question that person has left on the Net for up to several
years.
The implications are staggering. Suspicious spouses can check if
their partners have been seeking on-line romance in any of the Net's
many singles chat groups. Suspicious employers can spy on disgruntled
workers who may be spreading critical messages about the boss or
company in, say, an environmental forum. Web-savvy children can
spy on their parent's favourite hobbies and chat topics, and vice
versa. Insurance companies can secretly monitor customer's lifestyle
interests.
And private detectives can hunt down fugitives. Canadian Web sleuth
Carla Edwards runs Datatrac, a tracing company out of Casper, Wyoming.
Most of her clients are private investigators and bail-bond agencies.
"Everyone who posts on the Internet leaves a trail that can
be followed", Edwards said.
She uses DejaNews to track a person's interests, psychological
profile, and even physical location. For example, "if a subject
posts a vehicle for sale, often you will pick up details such as
a telephone number in the body of the ad, in addition to the vehicle
year and make", Edwards explained.
Most disturbing of all for a lot of people, perhaps, employers
now can check out job applicants' travels on the Net. "We are
frequently contracted to do background investigations on prospective
short-list candidates for executive positions in the oil-and-gas
and brokerage industries in Alberta", said Bill Fischer, who
heads Electronic Countermeasures Inc. of Calgary, a security-management
and consulting corporation. "We use DejaNews and other Web
tools to verify hobbies, interests, and attitudes. A search can
tell a lot about a person, good and bad."
DejaNews is the premier site for searching through the Internet's
vast array of public forums. A privately-held company owned by several
investors, including publishing giant Ziff-Davis, DejaNews makes
its money by selling advertisements on a site visited by more than
four million people every month. The site's main function is fairly
benign: to provides visitors with a central information directory
to more than 80,000 Internet discussion groups. Type in a keyword
term - sewing or Toronto Blue Jays, say - and you will find a list
of E-mail messages posted by other visitors with an interest in
the topic. Point your mouse on the title of any message, click,
and up pops the message. Another click and you can respond to the
group with your own comment.
But click on an inconspicuous link labelled "author posting
history" and you get that correspondent's complete message
history: Everything he or she has written to any other public forum
dating as far back as four years. Not just everything that person
has written to the sewing chat group, but everything he or she has
posted to every other chat group. You could find that your E-mail
sewing partner, for example, has also been fraternizing with white
supremacists or visiting one of the Net's ubiquitous pornography
groups. You can also directly type in anyone else's E-mail address,
such as your child's, and get the same kind of information.
Company spokesman Greg Wise says new technology and the falling
price of electronic data storage has made it all possible. DejaNews
has a remarkably large archive of more than 240 million E-mail messages,
accumulated over the past four years. "We certainly try to
do our part to make sure that users are aware all their messages
can be traced", he said.
Indeed, DejaNews carries a disclaimer on one of its policy pages
that few E-mailers unfortunately will ever bother to read: "Be
careful what you say. Information posted to any forum can come back
to haunt you."

How to Spy
Go to the DejaNews Web site (http://www.dejanews.com).
In the main search window, type in the E-mail address of the person
you want to spy on. A list of postings made by that author will appear.
To view all the postings made by a particular person, click on the
blue, underlined words: "author posting history".
Covering your tracks
Copies of Internet messages are usually stored in four places: your
personal computer's hard drive, the recipient's hard drive, and one
each on the large "server" computers that provide Internet
service for you both. An internet service provider can keep copies
of every message sent by its subscribers, sometimes for years. But
there are ways to minimize your chances of being spied on:
- Be vigilant:
- DejaNews, the Web site through which many people post messages
to public forums, offers a little-known way to prevent your E-mails
from being archived. Simply begin the body of every message with
"x-no-archive". You must do this for every message.
- Pseudonyms:
- You can shield your identity to an extent by using one of the
Web's many free E-mail services (such as Hotmail at http://www.hotmail.com
or YahooMail at http://www.yahoo.com)
and typing in an alias E-mail return address, such as neatguy@hotmail.com.
Keep in mind this does not hide your identity from the people
at hotmail or yahoo, and it only hides your real E-mail address,
not the contents of the message, which may inadvertently identify
you or be libellous. Should you make contentious remarks, you'd
have no legal protection because a court could order Hotmail or
Yahoo to divulge your identity.
- Encryption:
- This goes a big step beyond a simple pseudonym. Montreal-based
Zero-Knowledge Systems (http://www.zks.net)
has developed a program called Freedom that enables you to create
a sophisticated digital pseudonym that hides your true identity
- even from Zero-Knowledge. It also encrypts the contents of the
messages you send, so that no one other than your recipients,
not even Zero-Knowledge, will know what you've written. It will
be available in June at a cost of $75 (which gives you five pseudonyms
for one year).
