Weaponized AI: Inside The Criminal Ecosystem Fueling The Fifth Wave of Cybercrime

AI is no longer an emerging risk; it is now operational infrastructure for cybercrime.

Cybercrime has entered a new phase. What began as manual, opportunistic attacks in the 1990s has evolved through organized malware, Cybercrime-as-a-Service, and ecosystem-level supply chain attacks. Today, a fifth wave is underway – one defined by the weaponisation of artificial intelligence.

In this wave, AI is not simply enhancing existing tactics. It is industrialising crime, turning once human-driven skills – persuasion, impersonation, malware development – into scalable, on-demand services across the underground economy.

Group-IB’s Weaponised AI research reveals how this shift is unfolding in real time.

What’s driving the fifth wave of cybercrime?

Based on original investigations conducted by Group-IB’s global analyst teams, the report exposes how AI is being actively adopted and monetised by threat actors worldwide:

Group-IB’s monitoring of dark web forums shows a sharp surge in AI -related criminal activity over the past five years, with AI now embedded across the cybercrime value chain rather than used as an occasional tool.

 

Through infiltration of underground forums, marketplaces, and dedicated leak sites, Group-IB analysts uncovered a maturing criminal ecosystem that increasingly mirrors legitimate SaaS businesses – complete with subscription models, customer support, and rapid iteration.
