Unitel Hit by Cyberattack Ahead of High-Profile Stock Market Debut
Angola’s largest telecommunications operator, Unitel, disclosed a cyberattack on July 27 that disrupted voice, mobile data, and internet services nationwide. The incident occurred just hours before the company’s scheduled stock market listing on July 28 a key milestone in Angola’s effort to privatize state-owned assets and attract private investment.
The attack was detected at 02:20 local time (01:20 GMT) and targeted Unitel’s technology infrastructure, impacting over 21 million customers in a country of 39 million. While the company confirmed ongoing disruptions, it did not specify the nature of the attack or a timeline for full service restoration. Unitel’s initial public offering (IPO) had been oversubscribed by more than 20%, underscoring strong investor interest despite the disruption.
As of the latest update, Unitel stated that recovery efforts were underway, though services remained affected. The incident highlights the vulnerability of critical infrastructure during high-stakes financial events.
