Whoa, never thought of that, but blackhats certainly will.

If they get one celebrity, they could get all their friends.

I predict a second one of these https://wikipedia.org/wiki/2014_celebrity_photo_hack

Ironically this time iphone users will be protected.

Probably has engineering challenges past what you would normally face, which thankfully makes a 1B device botnet a little unrealistic. I can't imagine how you'd even begin to control such a thing, just a sequential numerical list of the clients is 4GB. Scary prospect though.

Not too far off.

There's your discovery layer: https://en.wikipedia.org/wiki/Kademlia

C&C: http://www.reddit.com/r/netsec/comments/2pmmfu/using_the_blo...

Persistence Layer: https://github.com/cockroachdb/cockroach

Dissemination Layer: https://en.wikipedia.org/wiki/Gossip_protocol

Sprinkle in some AES and public / private keys for verification and you're done.

Sequential list isn't needed.

(well, all the robust & stealthy large systems engineering together with the low level exploit knowledge is probably a little too much for one person to pull it off, but for a Hacking Team or nation sized actor it's quite doable)

The bot can call home to ask if/when more infections are desired, so the attack can elastically adapt to remain viable and not overwhelm the resources it needs.
