SECURITY
Fraud is a serious matter for businesses
, and there are some clever fraudsters always looking to exploit
security gaps in both large and small business and commerce websites
.
This extract is based on personal
experiences of running web sites , the extract is included as a
reality check for GoodSites clients , and site visitors , if you
agree or disagee send in your opinions for possible inclusion on
these pages
Here there are some discussions on some of the clever
ways naughty surfers are using the internet for their unfair advantage
, and what can be done to prevent this happening .
No1 Cookie Stuffing
This used to be a BIG problem , but
is fast becoming a thing of the past as more technology providers
provide anti-stuffing measures to combat this massive fraud potential
.
How it works - Fraudster X joins
1 or more affiliate programs (which pay you for referring traffic
via their banners which you place on your website). The idea is
you legitimately get paid based on the performance of your referals
- You advertise the product or service on your website and if some
one clicks the offer and buys from the advertiser you get a small
reward . Technology wise it works by storing a small file called
a cookie on the visitors PC , this identifies them with the advertising
provider , and usually has a time limit imposed , so if they click
through the banner , the affiliate gets paid if the visitor buys
within the time limit (which can be between 1 day to typically several
weeks) . Fraudster X however has worked out a clever little way
of bypassing the click , so that the visitor simply visiting the
page ( ie a web page impression ) results in the cookie firing off
, and this can be literally 100s of cookies , this is out right
fraud because the visitor has not decided they want the offer being
advertised and the cookie could even worse be for an unrelated product(s)
or service(s) . Say the bad affiliate adds several high street cookies
on a page to fire off as a cookie machine gun ( or cookie bombs
as they also know as ), then the visitor is quite likely to visit
one of the High St store web sites eventually if not on the same
day .
Prevention
Deterrants are usually employed here , any affiliate
program should include a clause to say that any affiliate behaving
in such a way will be terminated immediately and any commission
accrued forfeited . Then the affiliate managers job is to look out
for strange click patterns , eg: if you see several clicks happen
at the same time or bad conversion rates with high clicks ... Luckily
such practices stand out like a sore thumb for anyone reasonably
proficient in analysing their website stats reports on UVs impressions
clicks and referal pages etc , and few affiliates get away with
such prcatices long enough profit . Most are fly by night sites
- sites designed to make a quick profit and run ...
No2 Phishing
Phishing is a common practice , where rogue companies
or individuals contact you by email pretending to be someone else
- usally a trusted website such as a high street bank , or Ebay
or Paypal etc... They often create a site with a domain name that
is like the copy cat site and with a stolen logo and slogan etc.
to make everything legitimate , and then ask you for personal information
. If you are a member of Ebay and get an email saying your account
is about to be frozen , and to update your details you can be pretty
sure it's a hpishing attempt . Also you may get an email saying
Paypal has received a fraudulent transaction and asking you to login
, (but unknowingly you will be logging on to a different site designed
to trick you into entering you logging details).
UPDATE : The latest attempts are
emails pretending to be from your bank warning you of phishing attempts
, then asking you to logon to help them update their site ! It is
sad that some people may fall for these tricks
Prevention - Do not be caught out
!
Do not click through to sites from emails unless you
are 100% sure it is legitimate - always check the web address of
the link corresponds EXACTLY to what the merchant's real site is
called . Eg: for Paypal it would be http://www.paypal.com and not
http://www.paypal99.com ! If at all unsure do not follow the link
, instead open your browser and type the address of the site you
are sure about in at the address bar .
Also you can alert the real site to such activity
, eg: Ebay has a spoof emails contact , this will help alert others
.
Finally if you have an anti spam package make sure
you report the email . Some web host providers provide anti spam
packages with their pop email accounts as standard 1&1 anti
spam is a good example
Another good free email account with a very useful
SPAM button is Yahoo!
Mail , this has a pretty efficent spam filter , for any new
spam emails that get through , simply click the spam button and
it goes straight in the Bulk Folder .
