Paypal Scam Alert!

March 8, 2008 – 2:21 PM

Do you have a Paypal account? If so, then you need to be aware that, once again, someone is trying to steal your password.These scams are usually easy to spot because Paypal always logs you into your account using a secure page (https:// means secure). In this case, however, the con artist has registered a certificate for use on a secure connection. He has also disguised his web address to make it appear as if it led to Paypal’s web site.

Occasionally you may have come across a page on a web site that asks you to log in using a network password (example). You type in your user name and password and click OK to gain entry. There is a way to avoid having to enter your user name and password. You add your user name and password to the beginning of the internet address. http://my_name:[email protected]/passwd_protected/ is a good example of this.

The scammer’s email gives you a link to ki54ft.worldispnetwork.com/i.cgi, but it includes a user name and password for a password protected directory, and the user name happens to be www.paypal.com. This is the same cute trick used recently by a browser hijacker to fool people into thinking they were loading msn.com.At the web page linked in the email, there is a login form. If the victim fills in their password, they give this scammer their Paypal password, and his script combines that with their email address. After submitting the form, the cgi script redirects the user to the real Paypal login page. This is done in hopes that the victim doesn’t notice anything suspicious. The victim may not realize that anything is wrong until they get the email receipt of the scammer cleaning out their account.

Please, pass this warning along. Too many people fall victim to these scams, and this one is very convincing.

Most Web Surfers Oblivious to Web Site Collection of Personal Data

March 8, 2008 – 2:20 PM

U.S. Internet users are often unsuspecting of what goes on behind the scenes of their favorite Web sites. According to data from the Annenberg Public Policy Center of the University of Pennsylvania, 57 percent of U.S. Internet users incorrectly believe that when a Web site has a privacy policy, it will not share their personal information with other sites or companies. This misconception, among others, underscores the lack of education Internet users have about data flows, what the study calls, “…the invisible, cutting edge techniques whereby online organizations extract, manipulate, append, profile and share information about people online are part and parcel of how Web sites operate.”

While 59 percent know that Web sites collect information about them even if they don’t register, they don’t understand that data flows behind their screens invisibly connect seemingly unrelated bits about them. When presented with a common version of the way sites track, extract, and share information to make money from advertising, 85 percent of adults who go online at home said they would not accept it on even a valued site.

The Google Dance Viewer

March 8, 2008 – 2:17 PM

Author: Mark Horrell @ www.markhorrell.com

The Google Dance is the name given to the behaviour observed by the Google search engine during the monthly period when it updates its index.

Because the traffic to Google is vast, numbering hundreds of millions of queries a day to some 3 billion documents, it spreads its database across several data centres, each comprising thousands of individual servers. Since it aims to assemble a complete map of the web once a month, updating all its data centres with the new index can take several days.

Each time you query the main Google domain at www.google.com, the domain name itself could direct you to the IP number for any one of its data centres, depending on your location in the world and the relative loads in terms of internet traffic using the data centres’ servers.

Google runs two additional domains, www2.google.com, and www3.google.com, which are used as testing grounds for the new index after re-indexing has occurred and while the search engine’s relevance ranking algorithms and PageRank iterations are being re-calculated. Once the new index has been tested and its results deemed satisfactory, it is then transferred in turn to each of Google’s individual data centres.

Most of the time when you query Google, you will not observe this behaviour taking place. During the period of the transfer however, you may notice the results on Google ‘dancing’ up and down depending on which data centre the domain www.google.com is directing you to and whether or not that data centre has been updated with the new index. It is for this reason that the updating period is known as The Google Dance.

The Google Dance Viewer is simply a tool which allows you to query each of Google’s data centres from one convenient interface, and compare the results against those of the main Google site. If you are a webmaster, you can thus see whether the Dance is taking place and how the latest update may be affecting the ranking of your web sites.
