Brazilian Hacker Linked to Banco Master Scandal Arrested in Dubai Through International Police Cooperation

Victor Lima Sedlmaier, a suspect connected to the cyberattack group 'Os Meninos' involved in the Banco Master financial scandal, was arrested on May 16, 2026, in Dubai. This operation was coordinated between the Brazilian Federal Police, Interpol, and Dubai authorities, highlighting significant international cooperation. Sedlmaier had been on the run since the launch of the sixth phase of Operação Compliance Zero, a broad investigation spearheaded by Brazil's Supreme Court into alleged cybercrimes and financial misconduct linked to the now-defunct Banco Master and its former owner, Daniel Vorcaro.

Sedlmaier is accused of providing logistical support, including computer maintenance and AI software development, for the hacker group that reportedly conducted cyberattacks, telematic invasions, and illegal digital surveillance to benefit Vorcaro. Investigators believe he also participated in efforts to eliminate incriminating evidence following previous arrests. Notably, police discovered Sedlmaier had used false identification documents and was associated with Luiz Phillipi Machado de Moraes Mourão, a known enforcer for Vorcaro who died in custody.

The operation also resulted in the arrest of Henrique Vorcaro, Daniel's father, connected to leading a militia group called 'A Turma,' which allegedly provided personal security and conducted illicit operations for the former banker. Supreme Court Minister André Mendonça emphasized that Henrique Vorcaro was deeply involved in soliciting and financing these illegal activities.

Sedlmaier was apprehended at Dubai's airport and is expected to be extradited to Brazil, arriving at São Paulo's Guarulhos International Airport to face charges. This development marks a critical escalation in Brazil's crackdown on cybercrime and financial corruption surrounding Banco Master.

According to Andrei Passos Rodrigues, director-general of the Brazilian Federal Police, Sedlmaier had been operating in support of David Henrique Alves, identified as the hacker group's leader and currently a fugitive. The comprehensive international efforts in this operation underscore Brazil's commitment to pursuing individuals involved in sophisticated cybercriminal schemes.
