Various services have been doing ad-injection for at least five years so not
new - first noticed it around 2006. In fact, there are wordpress utilities
that do ad injection for bloggers. The bad stuff will probably not come
until you click on the 'extra' banner. Some easy notebook mitigation to do
while traveling:

1. Run only chrome or mozilla FF
2. turn off JS and cookies
3. carry your own router (firewall settings for MAC filter, without default
SSID, etc).
4. run Linux on trips (easy dual-boot setup, see
<http://en.wikipedia.org/wiki/Win32-loader_%28Debian%29>

Also note that a router will probably eat most of a data-line surge before
your notebook's ethernet port sees it. Routers are cheap compared to the
computer.

Subject: ad code injection?

Hi All,

I just found a disturbing trend used by some Internet providers, especially
ones in places like hotels. That being injecting code in to any web page
visited. As you know, I do not accept advertising for others on my website
http://emcesd.com but you may see ads I have not put there. Below is a clip
from an article on blogs.nytimes.com and a link to the full article. If you
ever see an ad on my website from someone else, can you please capture a
screen shot and send it to me? I do not use annoying techniques, like
blinking banners, on my web page, in fact it is just flat html with out even
javascript. I try to make my site as informative to engineers as possible
without flashy banners and such.

" On its Web site, a company called RG Nets, which makes Revenue eXtraction
Gateway, explains that its system rewrites every Web page on the fly so that
it can include a banner ad. “As you can see, the pervasive nature of the
advertising banner on all Web pages guarantees banner advertising
impression,” a narrator says in the video."

I am late this month on my Technical Tidbit because of my move from Silicon
Valley to Boulder City, NV, where I am at the moment.

Doug
