Most Wanted: Teen Hacker Cast and crew

– Allison Nixon as SELF

As the Chief Research Officer of a premier cybersecurity firm, Allison Nixon is the modern-day Sherlock Holmes of the digital underworld. Her firsthand testimony provides the narrative backbone of the investigation. Nixon doesn’t just explain the technicalities; she conveys the visceral, high-pressure chase of following a ghost across the internet’s darkest corners, making complex forensic work feel like a gripping detective story.

Nixon’s presence is formidable and essential. She translates the abstract world of data breaches and network vulnerabilities into a tangible, human story of pursuit and consequence. Her insights reveal the cat-and-mouse game between investigators and the hacker, offering a unique perspective on the immense challenge of attributing attacks and building a case that can stand in a court of law.

– Mikko Hyppönen as SELF

A legendary figure in cybersecurity, Mikko Hyppönen brings decades of global perspective to the crisis. As the Chief Research Officer at F-Secure, he operates as the series’ philosophical guide, contextualizing this specific teen hacker within the broader history and evolving landscape of digital crime. His commentary is filled with wit, wisdom, and a palpable concern for the future of our digital society.

Hyppönen’s role is to look beyond the immediate manhunt and ask the bigger questions. He explores the societal conditions that create such prolific young hackers, the ethics of vulnerability disclosure, and the geopolitical implications of cybercrime that knows no borders. He is the show’s moral and intellectual compass.

– Brian Krebs as SELF

The iconic investigative journalist and author of the essential security blog “Krebs on Security,” Brian Krebs is the tenacious outsider who breaks the story wide open. Krebs embodies the power of independent journalism, often working parallel to—and sometimes ahead of—official law enforcement agencies. His dogged pursuit of truth and his ability to connect disparate dots are crucial to the narrative.

Krebs provides the public-facing element of the investigation. His reporting not only informs the audience but often flushes the hacker out of hiding, turning his blog into an active player in the drama. His segments highlight the very real risks investigative journalists face when exposing powerful criminal entities.

– Aleksanteri Kivimäki as SELF

At the center of the storm is Aleksanteri Kivimäki himself, the Finnish hacker whose alleged actions form the basis of the global manhunt. His inclusion, whether through archival footage, police interviews, or his own statements, provides a chilling, unfiltered look into the mind of the accused. His testimony is the ultimate key to understanding the motives, whether they be financial, ideological, or purely for the thrill.

Kivimäki’s presence transforms the series from a simple investigation into a deep psychological profile. The documentary explores his background, his online persona, and the path that led a teenager to become one of the world’s most wanted cybercriminals, forcing viewers to confront the complex reality behind the headlines.

– Joe Tidy as SELF

BBC Cyber Correspondent Joe Tidy serves as the audience’s everyman guide through this complex saga. As a journalist who has covered the story from its inception, Tidy excels at translating technical jargon into accessible, compelling narrative. He is on the ground, speaking to victims and tracking the investigation as it unfolds in real-time.

Tidy’s reporting provides the human stakes. He is the connective tissue between the high-tech investigation and the ordinary people whose lives were shattered by it. His segments ensure the story remains grounded in its profound human cost, reminding us that behind every data point is a victim of crime.

The hunt was digital. The impact was human. Witness the true story on HBO Max, September 5, 2025.
