II would use something like UDP or IGMP and modify the packets slightly. I
know that most routers will just pass them on and not worry about a few
weird things.

Yes, its possible, I mapped out something on a high level that would
use rss/xml and would evade most detection methods on the network...
Problem comes in is that stuff gets detected at infection-time and
gets reverse engineered. Stealthy botnets is easy, stealthy infection
is trickier.

God Valdis,
Dont concentrate on the mundane, the core issue is the unpredictable

You have them all coordinate reading the news at 12:00 AM GMT.
You build some silly algorithm that ensures they pick the right article.

You know how the current amateur botnet offerings are basing domain
lists
off the current time to allow the 'good guys' to prepare?

Why not base the seed off something like a news RSS feed? I asked
some
whitehats when I was ruined in Washington DC and they couldn't tell
me.

If you're the botnet owner, you need to have some way to know what
domain
name your botnet will be looking for, so you can register it.

If you look at 11:06AM, see the top news story is something about Obama
flipping the Republican party the bird, and computes the domain name to
register based on that, but then at 11:07AM some editor at CNN pulls
that
headline and replaces it with "Obama sends obscene gesture to
Republicans"
before your bots wake up at 11:08AM and check what domain to use,
you're
screwed.
