Unitel, Angola's state-owned telecommunications giant, confirmed on Tuesday that a cyberattack has disrupted voice, mobile data, and internet services across the country.
The outage comes at a critical juncture for the company, which is preparing for its initial public offering (IPO) on the Euronext Lisbon exchange.
Unitel's listing is one of the most anticipated deals in Africa this year, with the government planning to sell a 15% stake in the company.
The attack has forced the operator to scramble to restore essential communications infrastructure while simultaneously managing the heightened scrutiny of potential investors.
The timing of the breach casts a shadow over the IPO, which was scheduled to open shortly after the incident.
