Colonial Pipeline attack shut down vast chunk of US oil distribution.
Incident laid bare vulnerability of public services to ransomware hackers.
Radio Davos examines what ransomware is and how it works.
The latest episode also features an exclusive interview with head of US Homeland Security.
At 5.30 in the morning of 7 May, an employee of a company called Colonial Pipeline found a ransom note from hackers on a work computer. By the end of the day, the pipeline that provides roughly 45% of fuel to the East Coast of the United States was shut down and soon people were panic-buying gasoline because of fears how long the stoppage would last.
The pipeline is open again now, but not before the company paid $4.4 million in ransom.
Ransomware is a big, international criminal enterprise, but what exactly is it and what can be done to stop it?
Radio Davos hears from two experts from the World Economic Forum's Centre for Cybersecurity and from Alejandro Mayorkas, U.S. Secretary of Homeland Security.
