The dark web is a hidden space on the internet where your activity can be anonymous and private. Among these dark websites, there’s a disturbing amount of apparent "murder-for-hire" sites offering hitman services. On the Sky News Daily, Sally Lockwood explores the use of "murder-for-hire" websites with hacker and dark web vigilante Chris Monteiro, while one victim tells us how dangerous they are. Also, Andy Greenberg, author of Tracers in the Dark: The Global Hunt for the Crime Lords of Cryptocurrency and senior writer at WIRED magazine, helps us understand what is being done to combat them.
