Death over SMS: someone is sending Australians scary text messages. They contain a lethal threat combined with extortion:
[M]essages...typically read "Someone paid me to kill you. If you want me to spare you, I'll give you two days to pay $5000. If you inform the police or anybody, you will die, I am monitoring you"
As with most spam strategies, this only requires a few responses to start paying off.
Now there's got to be an autocomplete joke in here...
