My very own security incident involving China (in a way):

[Jan 28 09:55:45] NOTICE[7593] chan_sip.c: Call from '' to extension '00442078420960' rejected because extension not found.

An attempt (within the public sip context) to call a number in England. The Chinese embassy in London. All attempts failed since the asterisk which logged that has no idea how to call the big phone network. Information from a lecture on SIP security suggests that this kind of attempts is a sort of ddos attack on a phone number.
