The Agency That Ghosted
Client: Harmattan FMRadio station · Tamale
Harmattan FM studios, Tamale · Late-night, wry
Harmattan FM's ad agency encrypted every ad schedule, sent an invoice and went silent. Nobody has the keys, and sponsors expect their slots on air tomorrow morning.
Who you'll work with
Ada MensahYour lead
Engineering Lead
Dry, warm underneath, short sentences. Notices how you did. Never gushes.
Salifu Mahama
Producer, Harmattan FM
Warm voice, dry jokes, runs on tea.
Tunde Bakare
Senior Developer
Friendly rival. Competitive banter, always generous in the end.
The client's system
Keys gone quiet
Unknown-key shifts, single-byte XOR and short-key Vigenère. English leaks through every one of them.
