One thing I noticed is that a few sites caching a lot of files for "easier" browsing. While this is nice and all, people who are being monitored have no idea this is going on in the background and end up paying the price.
One user I worked with on identifying her usage showed me this scenario. I traced it to a photography site that downloaded in the background many of the pictures on the site. While it made it nice to look around and the load times were fast - she was tagged as a heavy user, even though she didn't look at many of the pictures. I ended up using wireshark to confirm this. I shut down every process that might download (win updates, adobe, etc..) and went to the main page of this site and watched wireshark show me how much of the site was downloaded, even without doing anything on the site.
If this kind of thing can happen, imaging having a couple of windows open to sites such as this, while checking email or something. You end up looking like your a mad man online, when in reality, you're not. |
