We have been accustomed to think about botnets as a network of compromised machines – personal devices, IoT devices, servers – waiting for their masters’ orders to begin their attack, but Protego researchers say that many compromised machines are definitely not a requirement: botnets can quite as easily be comprised of serverless functions.
They created one on the Google Cloud Functions platform as a proof of concept and have calculated that the losses experienced by organizations whose account the botmasters are exploiting could reach tens (if not hundreds) of thousands of dollars.
