I didn't want to hijack the other threads hijack into who knows what it is and who doesn't. I used to be an IE6 relic until recently. I was dragged in chains, kicking and screaming at gunpoint into upgrading to the most extreme IE7 ! Now over half of the websites actually work !

But I wondered if maybe IE6 was somehow immune and since it piqued my interest I set forth to find out what it is. Sound like a virus actually. As we know some of them come back like roids almost no matter what you do, this because there are extra copies laying around and they just recopy themself. This seems like he same thing and IIRC it's told to do so in the registry. Would this be the same ? I am not afraid of regedit.

However I know that things seem to disappear from the internet so I have a propensity to save them (that's where alot of my porn collection came from). So I saved this :

"Use the code against itself. In your URL bar:
javascript:ec.set('uid', 12345);
Boom, done, evercookie.js wiped out the data for you. Until evercookies are made read-only I don't see this as being a major threat."

I would assume the 12345 part can be random. But then what if they are made read only ? That begs the question then why not just make regular cookies read only ?

And if an evercookie is made read only, why bother having multiple copies ?

I also found interesting that apparently it makes one of the copies into a PNG file. I wonder what an image editor would show if that was viewed. I used to play with images in a hex editor in the old 256 color days. What would that tbe called now, two bit color ? LOL.

I have some interesst in this shit, just because. I don't update virus scanners and all this shit, I just keep my disks handy and run off a small HD and keep all my data and all portable programs on another HD or two. In fact I am about to clone the bootdrive so that I don't even need to reload next time it gets FUBARed. Let's see ANYTHING infect a HD that is not even connected ! HAHA.

However it would be nice to know that at least for now, that this load is clean.

Now for a quick other question. If I empty the cache and delete cookies, and empty the recycle bin, and then clone the bootdrive, will those files be recoverable on the cloned drive ? The cloning program I use is from Seagate right now, and as it progresses I see the status bar with filenames. Does this indicate that it is not sector by sector ? I tend to think not because it is designed to transfer everything from smaller drive to a larger one. But of the part of the new partition is does use, is that a carbon copy so to speak or is it nothing but a boot sector and all the files ?

Note that everything is running just fine, but enquiring minds want to know.

That works for the standard demonstration EverCookie API. As soon as someone obfuscates the Javascript, you're hosed.
