“It gave us all goosebumps” says Sebastian Zwiebel, as he describes the moment his team shut down Hydra, the world’s largest darknet marketplace.
The website was a bastion of cyber-crime, surviving for more than six years selling drugs and illegal goods.
But, after a tip-off, German police seized the site’s servers and confiscated €23m (£16.7m) in Bitcoin.
“We’ve been working on this for months and when it finally happened it felt big – really big,” adds Mr Zwiebel.
