There are number of types cookie stuffing tricks , but i am here explaining Image cookie stuffing .Iframe cookie stuffing
Description: This is one of the oldest and most simplest methods out there. Most people who cookie stuff have started out using this method. Basically you put a 1 pixel iframe on your existing website and everytime someone visits your site, the affiliate page is loaded within the iframe and the cookies are dropped onto the visitors system.
Resource folder /iframes/1/
Description: You literally just take your affiliate link and make a 1 pixel iframe with the source being the affiliate link.
Pros: The biggest pro point of this is that its extremely easy and just about anyone can do it without even having to think about it. To improve your chances of not getting discovered running the hidden iframe you should ensure that there is actually a [ebay] banner or texual link on the same page as the iframe so that at first look the advertiser will think you are sending them genuine traffic.
Cons: This is quite an easy method to pick up on. The merchant or affiliate company simply needs to view the html source code of your site and see the hidden iframe.
Resource folder /iframes/2/
Description: You again go with the same idea of a 1 pixel iframe but instead of having the iframe in your normal page you include an external javascript file which obfuscates the iframe html code. You can find thousands of free online services which will obfuscate your code by searching for ‘html encryption’. For example you could create stats.js which holds the obfuscated iframe and then include it within your normal page.
Pros: Even if the merchant checks your html code, they’re just going to see normal html and are unlikely to think anything of the javascript file. Even if they do then they won’t understand the contents of the javascript file because it’s been obfuscated.
Cons: Some advanced merchants might go to the extreme of checking all your javascript files and then de-obfuscating your code.
Resource folder /iframes/3/
Description: You may be thinking that the affiliate is going to check your external javascript files and then de-obfuscate the html. Okay well how about another layer or protection! We will use htaccess to tell the server to treat our JS file as a php file and then check the referer. If there is no referring page then we know someone has gone direct to the javascript file and we will output some bullshit JS else we output the real stuff.
Pros: Even if the merchant checks your html code, they’re just going to see normal html and are unlikely to think anything of the javascript file. Even if they do then they won’t understand the contents of the javascript file because it’s been obfuscated.
Cons: Again if you get a merchant on interweb steroids then they may send a fake referer to the javascript file to see if you’re cloaking the content based on referer. Very unlikely but possible. Another problem is that if they sniffed the raw packets when viewing your main site then they’d see the code come in. This is even more unlikely and they’d still have to them de-obfuscate your code.
Overall pros of the iframe methods: These methods can be used very simply and setup extremely quickly. They’re the starting step for most cookie stuffers and give you a good introduction into how it works. You would work upon these scripts with different ways to protect yourself from being caught.
Overall cons of the iframe methods: The biggest con of this is that at the bottom of the visitors browser window they might spot the affiliate url as the page is loaded in the background.
