f your phone were compromised, would you even know?

Most cybersecurity defenses are built to stop loud, disruptive attacks like ransomware. But the most serious threats to mobile devices often look very different. They are expensive, targeted, and designed for espionage rather than disruption.

In this episode of THEOS Cybernova, host Paul Jackson speaks with Bill Marczak, a senior cybersecurity researcher at the University of Toronto’s Citizen Lab, about the realities of mobile phone espionage. They explore why smartphones have become a platform of choice for spying, how attacks can remain invisible to the user, and what makes mobile threats fundamentally different from traditional cybercrime.

What really happens when a cyberattack becomes a criminal investigation?

In this episode of THEOS Cybernova, Paul Jackson speaks with Steve Santorelli, formerly of Scotland Yard, whose career spans Microsoft’s Internet Crimes Investigation Team and Team Cymru.

They explore how cybercrime investigations succeed in the real world: why trust and community matter as much as technical skill, how speed determines whether evidence survives, and why cyber threat intelligence only creates impact when it can be acted on. The conversation also looks at cross-border investigations, collaboration between law enforcement and industry, and the role of trusted forums like RISE in turning intelligence into outcomes.

A grounded discussion on cybercrime investigation and the human relationships behind effective action.
