Surfing the darknet — the part of the internet that lies beyond a normal web browser's reach, and is a haven for an astonishing amount of criminal commerce — has never been easier, or more popular.
Users access the darknet via The Onion Router, or TOR, which disguises a their identity by routing traffic through a complex network of servers.
While not everything that happens there is criminal (Facebook said that more than a million people now access via TOR every month, up from half a million less than a year ago, often activists living under totalitarian regimes), the criminal activity is what stands out to a visitor.
"The darknet is going mainstream," said Radware security researcher Daniel Smith.
