Namibia recorded more than half a million cyber vulnerabilities between April and June this year, prompting the Namibia Cyber Security Incident Response Team (Nam-CSIRT) to urge organisations to tighten their cybersecurity measures as threats continue to escalate.
Communication Regulatory Authority of Namibia chief executive Emilia Nghikembua, in a statement released on Wednesday, says the increase highlights the need for organisations to address exposed services, protect digital identities, install security updates promptly and report incidents early.
“The newly launched national cybersecurity incident management guidelines 2026 provide a framework for improving cyber incident detection, reporting and response,” she says.
She stresses that their success depends on widespread implementation and collaboration across sectors.
According to Nam-CSIRT’s second-quarter cybersecurity newsletter, 513 921 cyber vulnerabilities were detected during the reporting period, representing a 39.8% increase from the previous quarter. Cyber events also rose by 56.7% to 161 547 incidents.
The increase was largely driven by exposed remote management and legacy network services.
Open CPE WAN Management Protocol accounted for the highest number of vulnerabilities at 320 778, followed by the Network Time Protocol Version report with 52 420 detections and Accessible Telnet at 42 941.
Nam-CSIRT also recorded a sharp rise in distributed denial-of-service participant events, indicating that some systems may have been compromised and used in cyberattacks.
The quarter further saw the emergence of ransomware and extortion groups such as Bavacai and Black X, which target organisations by stealing and encrypting sensitive data.
