Cybersecurity threats are no longer limited to sophisticated malware built in the shadows. Increasingly, open-source tools-widely used for legitimate testing and development-are being exploited by cybercriminals to breach financial institutions across Africa.
This evolution marks a significant shift in attacker behavior. Open-source frameworks such as Metasploit, Cobalt Strike, and Empire are enabling attackers to conduct highly effective campaigns with minimal technical barriers and low financial cost.
For banks and financial firms, especially those operating in emerging economies, this development introduces a new wave of risk-one that is silent, persistent, and often difficult to detect using traditional defenses.
The Mechanics Behind the Exploits
Adversaries are adopting a multi-stage approach using open-source tools:
- Initial compromise through phishing, VPN abuse, or misconfigured servers
- Tool deployment to establish footholds and execute lateral movement
- Credential harvesting and remote execution across internal systems
- Data exfiltration of sensitive financial and customer information
- Log evasion and artifact deletion to mask their tracks
These stages reflect a well-orchestrated, low-noise intrusion lifecycle that can remain hidden for months if organizations lack deep detection capabilities.
Why Financial Institutions Are Being Targeted
- Outdated infrastructure vulnerable to known exploits
- Resource limitations in cybersecurity budgets and staffing
- Heavy reliance on VPNs and remote access for distributed operations
- Rapid digitization without equally rapid security integration
- Lack of threat intelligence sharing within and across national borders
African financial ecosystems are rapidly growing-and so is the attack surface.
Building a Modern Defense Framework
To safeguard against open-source-based threats, COE Security recommends an adaptive cybersecurity strategy focused on the following pillars:
1. Real-time Threat Detection
Deploy endpoint detection and response (EDR) solutions that are capable of identifying unusual behaviors-such as the execution of known open-source binaries or unusual PowerShell activity.
2. Zero Trust Architecture
Apply a zero trust model across endpoints, users, applications, and network layers-ensuring that no entity is automatically trusted, regardless of its origin.
3. Vulnerability and Patch Management
Establish clear service-level agreements for vulnerability remediation and automate patching across operating systems, servers, and software libraries.
4. Security Awareness and Simulation
Train employees not just on generic phishing, but on real-world attack vectors including credential harvesting, shadow IT abuse, and reconnaissance detection.
5. Threat Intelligence and Collaboration
Partner with industry peers, CERTs, and regional ISACs to share insights and indicators of compromise (IOCs) tied to open-source tool misuse.
Conclusion
Open-source frameworks have made security testing more accessible. Unfortunately, they’ve also empowered malicious actors with the same accessibility. Financial institutions cannot afford to wait until an intrusion reveals itself through customer impact or regulatory violation.
At COE Security, we believe that trust in digital financial systems must be built not just through compliance, but through constant threat anticipation, detection, and response.
