Extortion attacks have risen since DD4BC kicked things off last year. DD4BC peaked in July and the Armada Collective took over after that, sending out emails threatening attacks unless the victim(s) made ransom payments in bitcoins.
The most recent round involved many ransom demand letters, but, as far as many observers can tell, very little follow through.
Now we have Lizard Squad, or at least, someone claiming to be that group, spamming over 70 Akamai customers with identical ransom demands, all of which seemed to be copied from the Armada Collective emails.
