Web attacks, on-device attacks, spyware, back door infections amongst other forms of internet propelled hacking have remained on the increase in the West African sub-region.

According to data from Kaspersky, a global cybersecurity company, Sub-Saharan Africa saw 42.4 million web attacks and 95.6 million on-device attacks detected in the first half of 2025.

The region recorded more than a double increase in spyware; 64% more password stealer attacks and 12% more backdoor infections compared with the same period of last year.

These statistics are shared ahead of Kaspersky’s participation in GITEX Nigeria, one of the region’s most significant technology security tools blocked more than 1.46 million online attack attempts on users.

With these threats (that include phishing scams, exploits, botnets, Remote Desktop Protocol attacks, and Network spoofing such as fake Wi-Fi networks), nearly one in five people in the country (19.9%) were targeted.

In the same period, 4.97 million on-device incidents were blocked, where 28.6% of Nigerian users faced malware delivered via infected USB drives, CDs, DVDs, and hidden installers, including ransomware, worms, backdoors, trojans, password stealers, and spy ware.

Kaspersky’s analysis shows a 66% increase in password stealers in Nigeria in H1 2025 compared to the same period in 2024, along- side a 53% increase in spyware blocked. Exploits targeting vulnerabilities in applications like Microsoft Office also remain prevalent.

Though the overall number of phishing detections decreased by 52%, phishing threats became more targeted, focusing on specific topics, for example, phishing specifically related to financial topics (banks, e-shops, payment systems) was on the rise and grew 46% (Kaspersky recorded over 595 000 detections of finance related phishing in the country).

Industrial environments are subject to cyberthreats as well: at- tacks on 26.5% of ICS (Industrial Control Systems) computers in Nigeria were blocked by Kaspersky solutions in H1 2025.

There are likely significant problems with virus and worm threats, especially affecting the construction, ICS engineering and integration, power energy, and biometrics industries. Africa in general has one of the highest rates of ICS computers on which malicious objects were blocked.
