Africa faces surge in cyberattacks exploiting financial sector vulnerabilities

Fast Facts

1. Africa experienced a peak in cyber attacks targeting financial and government sectors, with Angola and Nigeria leading in attack intensity, emphasizing increased regional threat levels.
2. The surge in ransomware incidents, especially in North America, highlights the continued growth of Ransomware-as-a-Service (RaaS) and targeted attacks on business services.
3. Widespread use of Generative AI tools internally poses a significant data leakage risk, with over 90% of organizations experiencing prompts that threaten sensitive information security.

Threats, Attack Techniques, and Targets

In April 2026, Africa’s financial sector and government organizations faced increased cyber threats. The global attack volume grew by 10 percent month-on-month and 8 percent year-on-year. Specifically, Africa saw a weekly attack average of 2,940 incidents per organization, which is higher than the global average. Countries like Angola and Nigeria had the highest attack intensity, with over 4,500 attacks weekly per organization. Kenya and South Africa also experienced notable attack levels. These threats mainly targeted the financial services and government sectors.

Attack techniques included ransomware campaigns and malicious use of Generative Artificial Intelligence (GenAI) tools. Ransomware activity increased with 707 reported incidents, a rise of 5 percent from the previous month. Threat actors used ransomware groups operating under the Ransomware-as-a-Service (RaaS) model. Meanwhile, adversaries exploited GenAI prompts—19 percent of prompts contained sensitive data, and one in 28 posed a high risk to sensitive information. These tactics aimed to compromise financial and government data security.

Targeted sectors involved financial services and government agencies. These are high-value targets due to the sensitive and critical nature of their data and operations.

Impact, Security Implications, and Remediation Guidance

The increase in cyber attacks poses serious risks to Africa’s financial and government sectors. Ransomware incidents can disrupt services, cause data loss, and lead to financial damage. The use of GenAI tools without proper security measures raises concerns about data leakage and insider threats.

These threats significantly threaten operational continuity and data confidentiality. They also highlight the need for stronger security controls, particularly around ransomware defenses and AI governance. Organizations should strengthen their cybersecurity measures and train staff about evolving attack techniques.

If organizations face these challenges, they should consult with their cybersecurity vendors or relevant authorities for specific remediation guidance. It is recommended to implement robust backup strategies, monitor AI tool usage closely, and adopt advanced threat detection solutions. These actions will help limit the impact of ongoing threats and improve overall security posture.
