Hello
I want to know how to implement a real DOS in the real cellular network
using RACH Flood.As you know, using OsmocomBB ,you can only send flood to
one ARFCN at one time, so the phone can seaching for another ARFCN. So I
think the RACH Flood is less effective in practice, how about it? and if
not,a better suggestion on DOS in Cellular network?
Thanks!

Why not just jam the uplink? There's no particular reason to actually
send any RACHs or the like.

It's simply orders of magnitude more effective: the amount of energy required to jam
entire cell is way bigger than the amount required for RACH transmission. This also
makes it much harder to locate the attacker. To put it other way - it's just
"greener" kind of DoS :)
Getting back to original question - one solution would be to use several phones to
run few osmocom stacks in parallel, each targeting its own ARFCN. Those phones are
dirt cheap anyway :)

While we do research on cellular security on this list, I don't think we
endorse, encourage or otherwise help anyone to participate in hostile
and/or illegal activities.
You clearly talk about a a "DoS in the real cellular network", which
clearly sounds like you have some malicious motives and are not into
this for research.
Maybe you can explain more about yourself, why you are interested in
this and what the exact application is.
Regards,
Harald

my turn:
Hello,
I want to bring down the entire internet. I think I can do that in practice on
my LAN by DOSing the DNS server, but on the internet there are others. So I
think a DDOS on all root servers should be more efficient, how about it? Do you
have a better suggestion?
;-)
Have a nice week end!

Sebastien
