How it works & targeted industries

  1. Attackers will send a notice to your company that they’ll DDoS your organization in ~a week unless you pay a ransom in Bitcoin (usually between $110,000 — $230,000).
  2. Various industries have been targeted

Ways to mitigate*

  1. Have adequate DDoS protections in place.
  2. It’s important to note that not every organization that received a threat got DDoS’d.

What to do if you do get RDDoS’d*

  1. Don’t pay the ransom
  2. Initiate your security incident response and BC/DR plans, which may include contacting law enforcement
