India’s leading technology magazine DIGIT, has had in its November 2007 issue, a serious look at what one Indian security analyst claims is a flaw in Google’s AdSense. A Indian named, Manish Arora has found a way to cheat adsense and make thousands of US$ quickly. His claim has been verified by DIGITians and when they reported it to Google, they doesn’t seem to take it seriously. This has endangered the interests of adwords users. Is google working on the fix or is it something they doesn’t care about or is it the way they make money themself? Only time will tell this. Now the question is what he exactly did and the even more interesting how he did it?

What he did?

He had gone through number of articles/reports on Pay Per Click mechanism including the report of Dr. Tuzhilin (Professor of Information Systems at the Stern School of Business at New York University), who evaluated Google’s invalid click detection efforts.

After going through all those articles and analyzing Google’s code he found a way to simulate human behavior in click generation and page impressions in proper (acceptable) ratio from different geographic location (IP address) and was able to credit thousands of dollars in his AdSense account (By not a single human being generated click)

By observing the working of their system he was able to point out how ads are served from their servers and how can he stimulate the process from his own server by a script made by him
