Hi All,
I have just seen a number of IPs trying to brute-force my VoIP server
from Microsoft network. For example, 13.90.148.133, 20.55.203.249,
40.76.244.210... Traceroute really goes to MSN. More than a half of all
usual attempts to hack my Asterisk I got today, came from MSN.
What is happening? Am I missed something?
