Zero-Day Weaponization: APT Groups Exploit Unpatched Vulnerabilities in Africa

Introduction

In recent years, Advanced Persistent Threat (APT) groups have intensified their cyber operations in Africa, leveraging zero-day vulnerabilities to infiltrate critical infrastructure and government systems. These sophisticated attacks underscore the pressing need for robust cybersecurity strategies to safeguard national assets and sensitive information.

Zero-Day Vulnerabilities and Exploitation

A zero-day vulnerability refers to a software flaw that is unknown to the vendor and, consequently, lacks a patch. Cyber actors exploit these vulnerabilities to gain unauthorized access, often before the software developer becomes aware and releases a fix. The exploitation of zero-day vulnerabilities is particularly concerning due to the lack of immediate defenses against such attacks.

APT Groups Targeting Africa

Several APT groups have been identified targeting African nations, employing zero-day exploits to achieve their objectives:

• RedJuliett: This group has targeted organizations in Djibouti, Kenya, and Rwanda, exploiting vulnerabilities in firewalls, VPNs, and load balancers to gain initial access. Their activities have affected sectors including government, finance, manufacturing, and agriculture. (ics-cert.kaspersky.com)

• UNC3886: This actor has targeted organizations in Egypt, Jordan, Russia, Vietnam, and Zambia, exploiting vulnerabilities in FortiOS and VMware technologies. Their targets span government, telecoms, technology, aerospace, defense, and utilities sectors. (ics-cert.kaspersky.com)

Exploit Broker Transactions

The dark web has seen a surge in exploit broker activities, with numerous listings for zero-day vulnerabilities. Between January 2023 and September 2024, Kaspersky identified 547 listings for exploits targeting software vulnerabilities, with half involving zero-day and one-day vulnerabilities. The average cost for remote code execution exploits was approximately $100,000. (kaspersky.co.za)

Notable Exploitation Cases

• SAP NetWeaver Vulnerability (CVE-2025-31324): In May 2025, a critical zero-day in SAP NetWeaver was exploited, compromising over 400 servers worldwide. The flaw allowed unauthenticated attackers to upload malicious binaries, leading to code execution and lateral movement within networks. (zafran.io)

• Erlang/OTP Vulnerability (CVE-2025-32433): In August 2025, a zero-day vulnerability in Erlang's Open Telecom Platform was exploited, allowing unauthorized access and arbitrary command execution. This flaw affected critical network infrastructure, including OT and 5G environments. (ics-cert.kaspersky.com)

Conclusion

The exploitation of zero-day vulnerabilities by APT groups in Africa poses a significant threat to national security and economic stability. It is imperative for organizations to implement proactive cybersecurity measures, including regular patching, network monitoring, and employee training, to mitigate the risks associated with these sophisticated attacks.
