The choice of communication methods, such as WhatsApp and Zangi, influenced the outcome of a clandestine operation related to an alleged coup against President Bola Tinubu's government. Retired navy captain Erasmus Victor, facing treason charges, mentioned being recruited to find financial backers for the coup by Colonel Mohammed Ma’aji, who introduced him to Zangi for its security features. Zangi claims it does not store communication histories and uses end-to-end encryption, but investigators may still access data on users' devices. The investigation includes evidence from devices rather than relying solely on messaging companies. Mr. Victor and his co-defendants have denied wrongdoing and are challenging the admissibility of their statements in court.
