Around the world, cyber criminals are holding companies hostage in a spate of cyber attacks that are forcing victims to pay out millions to keep their businesses online. Companies, schools, governments and hospitals are all being targeted by organised and sophisticated criminal gangs - but now law enforcement is fighting back and the FBI is leading the digital charge. Aaron speaks exclusively to FBI Cyber Division Assistant Director Bryan Vorndran about this global cyber battle - and how following the money helped them recover the cryptocurrency ransom paid by Colonial Pipeline. We also discuss what businesses and governments can do with IronNet Security boss General Keith Alexander, an Amazon board member and former NSA chief and Brandon Wales, the man in charge of America's top cyber agency, CISA.
