Cybercriminals Target Africa's Critical Infrastructure Amid Rising Threats

Executive Summary

In early 2026, Africa faces a growing threat from cybercriminals targeting critical infrastructure sectors such as power grids, water systems, industrial control systems (ICS), healthcare, and the financial sector. These attacks pose significant risks to national security and economic stability across the continent.

Current Threat Landscape

Cybercriminal activities in Africa have escalated, with a notable increase in attacks on critical infrastructure. In the third quarter of 2025, hacktivist attacks on ICS nearly doubled, accounting for 25% of all hacktivist activities by September. (cyble.com) This surge indicates a shift from traditional cybercrimes to more sophisticated attacks targeting essential services.

Notable Incidents

• South Africa: In 2025, the country experienced a significant breach in its power grid system, leading to widespread outages. The attack exploited vulnerabilities in the grid's SCADA systems, highlighting the risks associated with the convergence of IT and OT networks. (it-online.co.za)

• Nigeria: Between October and November 2025, Operation Sentinel, led by Interpol, resulted in the arrest of 574 suspects across 19 African countries. The operation targeted cybercrimes, including attacks on critical infrastructure, with estimated financial damages totaling over $21 million. (tomshardware.com)

Emerging Threats

The integration of artificial intelligence (AI) into cybercriminal activities has introduced new challenges. AI-driven attacks, such as automated phishing and identity theft, have surged across Africa. Organizations in countries like Nigeria, Ethiopia, and South Africa are facing thousands of weekly attacks, leading to widespread disruption and harm. (oecd.ai)

Recommendations

To mitigate these threats, the following measures are recommended:

• Enhanced Security Protocols: Implement robust cybersecurity measures, including regular system updates, intrusion detection systems, and comprehensive monitoring of ICS networks.

• Staff Training: Conduct regular training programs to raise awareness about cyber threats and promote best practices among employees.

• International Collaboration: Strengthen cooperation with international law enforcement agencies to share intelligence and coordinate responses to cyber threats.

Conclusion

The increasing sophistication of cybercriminal activities targeting Africa's critical infrastructure necessitates a proactive and coordinated response. By implementing comprehensive security measures and fostering international collaboration, African nations can enhance their resilience against these evolving cyber threats.
