"... while everybody is talking about high class exploits and cyberwar, four
simple stupid default telnet passwords can give you access to hundreds of
thousands of consumer as well as tens of thousands of industrial devices all
over the world."

"So, how big is the Internet?
That depends on how you count. 420 Million pingable IPs + 36 Million more
that had one or more ports open, making 450 Million that were definitely in
use and reachable from the rest of the Internet. 141 Million IPs were fire-
walled, so they could count as "in use". Together this would be 591 Million
used IPs. 729 Million more IPs just had reverse DNS records. If you added
those, it would make for a total of 1.3 Billion used IP addresses. The other
2.3 Billion addresses showed no sign of usage."


Interesting stuff.
