The new practice of typo-squatting is luring consumers to sites they think represent well-known brands where they are subjected to scams and e-mail harvesting – while the sites generate additional revenue via click-through advertising. 

Typo-squatters register domains using common misspellings of popular brands, products and people to redirect consumers to alternative web sites, according to a new McAfee report ""What’s in a Name: The State of Typo-Squatting 2007".
To quantify the scope of the study, McAfee reviewed 1,9-million variations of 2 771 of the most popular domain names.
"Typo-squatting illustrates the Wild West mentality that remains dominant in major portions of the Internet," says Chris van Niekerk, regional director: Africa at McAfee. "Even at its most benign, this practice takes consumers to places they never intended and penalises legitimate businesses by siphoning customers away or making them pay a charge to reacquire customers. At its worst, typo-squatting leads to online scams, ‘get-rich-quick’ offers and other risks."
The study cites the iPhone mania as a recent example of typo-squatting, noting that even though Apple’s new phone appeared just a few months ago, there will likely be at least 8 000 URLs using the word "iPhone" by the end of this year. Some will be fan sites or rumour sites, while others will be run by hackers and scammers. What most have in common is that they have no affiliation with Apple.
"What’s In a Name: The State of Typo-Squatting 2007" quantifies both the significant scope of the overall problem and also the differences among major web categories.
Some of the key findings are:
* A typical consumer who misspells a popular URL has a 1-in-14 chance of landing at a typo-squatter site;
* Children’s sites are heavily targeted: more than 60 of the most squatted sites are designed to appeal to the 18-and-under demographic, with squatters targeting domains like, and;
* Some typo-squatters take advantage of typing errors to expose children to pornography. In fact, 2,4% – or more than 46 000 – of the typo-squatter sites tested include some adult content and some of those sites are squatters of children’s properties;
* The five most highly squatted categories are: game sites (14% likelihood of being squatted) like, and; airline sites (11,4% likelihood) such as, and; mainstream media sites (10,8%) such as, and; dating sites (10,2%) such as, and; and technology and web 2.0-related sites (9,6%);
* Automated ad syndication services enable many typo-squatter sites to make money. In fact, one search engine’s ads show up on 19,3% of all suspected typo-squatter sites in this study;
* The five non-US countries most likely to have popular sites squatted are the UK (7,7%), Portugal (6,5%), Spain (5,9%), France (5,4%) and Italy (4,1%); and
* The five non-U.S. countries least likely are the Netherlands (1,5%), Israel (1,1%), Denmark (1%), Brazil (0,9%) and Finland (0,1%).
The study notes that typo-squatting is not a new phenomenon – cyber-squatting cases filed with the World Intellectual Property Organization’s arbitration system increased 20 percent in 2005 and another 25% in 2006, but they are increasing.
The emergence of new, top-level domains, automatic registration tools and the proliferation of parking portal sites that make it easy to generate pay-per-click revenue from squatted sites are all contributing to its growth.
