What would you do if you saw the following Google Adword?
“Is your PC virus-free? Get it infected here!”
This Ad was displayed 259,723 times and clicked on 409 times. That’s a click-through-rate of 0.16%. Would you consider this to be bad? The campaign’s costs summed up to a miserable $23 (€17).
Thankfully this ad was created for statistical purposes not with malicious intent.
Didier Stevens wanted to test how easy it is to lure users in clicking on a drive-by download. To make things easier for the average user, Didier used an evident malicious phrase and still users clicked away.
