Unitel Angola: a cyberattack 24 hours before a historic IPO

On Tuesday 28 July 2026 at 02:20, Unitel, Angola's telecoms leader with more than 21 million subscribers, was hit by a major cyberattack less than 24 hours before its listing on the BODIVA exchange. Voice, mobile data, payment terminals and banking flows were paralysed, just as the state was selling 15% of the capital for about $327 million. Yet the IPO was 21% oversubscribed and the share climbed 24.88% on its first day of trading. For boards, CISOs and DPOs, the lesson is clear: cyber-resilience is a financial variable, and Angola must speed up its legal framework for operators of vital importance. Discover in our carousel the full autopsy of this attack and the lessons to draw from it.
