O_o 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?
