I came across this interesting article that talks about a Trojan; not any Trojan but a Trojan that automates PPC click-fraud that is currently targeting Google and Yahoo (http://www.securitypronews.com/news/securitynews/spn-45-20080312ClickFraudTrojanTargetsGoogleYahoo.html).
What’s interesting about click-fraud is the little amount of attention that it receives in the media in comparison to Identity Theft and the other horrors of the Internet. In fact you are more likely to see news on the latest and greatest zombie-bot net then click-fraud.
However; many companies who have paid good money for Pay-Per-Click (PPC) advertising are falling victim to false impressions due to the rising click-fraud movement in America.
According to Click Forensics the annual click-fraud rate has grown by 28.3%; that’s nearly a quarter of all on-line advertising http://www.clickforensics.com/Pages/ClickFraudIndex.aspx.
For the worst part bot-nets are being used to automate PPC clicks in order to ensure that the activity looks authentic.
So this leaves us with one question, is your PC part of a click-net.
