The FBI has issued an advisory to businesses over a recent string of DDoS extortion attempts. The perpetrators are claiming to be affiliated with Anonymous or Lizard Squad, and their demands threaten sustained attacks unless a Bitcoin payment is made.
Between April and May of 2017, the FBI says at least six companies received emails claiming to be from “Anonymous” or “Lizard Squad” making threats of DDoS attacks within 24-hours unless the company paid a ransom demand in Bitcoin.
“The email stated the demanded amount of Bitcoin would increase each day the amount went unpaid. No victims to date have reported DDoS activity as a penalty for non-payment,” the FBI alert goes on to explain.
This week, the FBI says they’ve investigated hundreds of these cases, including several in Indiana – home to several major companies, the Indy 500, and this reporter.
