In 2000, a 15-year-old Montreal student named Michael Calce, known online as MafiaBoy, knocks Yahoo, Amazon, eBay, Dell, eTrade, and CNN offline within days, causing millions of dollars in damage and exposing how fragile the internet's biggest sites really are. This film follows Calce alongside investigator Donnie Werner, who tracks organized Russian cybercriminal networks running extortion and fraud operations across the web. Interviews with hackers and security researchers lay out the tools of the trade: botnets, denial-of-service attacks, and the black markets where stolen data changes hands. The film cites estimates that cybercrime costs the global economy more than $500 billion a year, framing individual break-ins as part of a much larger, ongoing conflict rather than isolated incidents. Calce's own account of his teenage exploits gives the film its clearest window into motive, showing how curiosity and bravado, not just greed, can bring down infrastructure companies assume is secure. The picture that emerges is of a battlefield with no fixed front line, fought by teenagers and mafias alike.
