Brazilian police arrested IT worker João Roque for allegedly aiding a cyberattack that stole over $100 million through the PIX banking system.
Roque is accused of selling system access and developing a tool for fund diversion, claiming he only communicated with criminals via phone and changed devices frequently to avoid detection.
The cyberattack targeted multiple financial institutions, leading to at least six being impacted, resulting in the market being shaken.
Authorities have frozen $270 million, suspended part of C&M's operations to prevent further attacks, and confirmed the company's systems were not the source of the breach.
