Introduction: Rising Cyberattacks in Africa’s Financial Industry
The African financial sector is facing a growing cyber threat from a sophisticated hacking group identified as CL-CRI-1014. Detected by Palo Alto Networks’ Unit 42 research team, this campaign has been active since at least 2023 and is notable for its strategic use of widely available hacking tools combined with stealthy operational methods. By focusing on financial institutions across Africa, these attackers are leveraging open-source frameworks and remote administration software to gain access, maintain control, and then sell that access on the dark web. This new wave of cybercrime highlights the evolving threat landscape targeting Africa’s critical financial infrastructure.
Overview of the CL-CRI-1014 Attack Campaign
Unit 42 uncovered that CL-CRI-1014 operates primarily as an Initial Access Broker (IAB). This means the group specializes in breaching networks to establish a foothold, which they then sell to other malicious actors. The tools in their arsenal are largely open source or publicly available software, such as PoshC2, a powerful attack framework capable of deploying implants written in PowerShell, C.NET, and Python. They also use Chisel, a tunneling utility that helps bypass firewall protections and facilitate covert network communications.
The attack chain follows a multi-step process: first, the threat actors use Microsoft’s PsExec to remotely connect to proxy machines within the target’s network. Chisel is then deployed to tunnel through the network, allowing the attackers to spread laterally across multiple devices. Once inside, PsExec is again used to deploy PoshC2 implants for reconnaissance and control, as well as to run PowerShell scripts that install Classroom Spy—a remote administration tool with extensive spying capabilities.
Classroom Spy is particularly intrusive, enabling attackers to monitor live screens, log keystrokes, capture audio and video through webcams and microphones, access terminal commands, and collect system information. This grants the hackers extensive control and insight into compromised systems.
In order to avoid detection, CL-CRI-1014 employs several evasion techniques. They pack their malware to obscure its signature, sign tools with stolen digital certificates to appear legitimate, and even mimic the icons of trusted software products. Notably, there is no indication that the attackers exploited software vulnerabilities, suggesting their approach relies heavily on social engineering or other means to gain initial access.

The discovery of
The use of open-source and publicly available tools like PoshC2 and Chisel also reflects a strategic choice: by relying on well-known, legitimate tools, the attackers can blend in with normal network activity and reduce the chances of detection by traditional signature-based security systems. The deployment of Classroom Spy adds an aggressive layer of surveillance and control that is particularly worrying for financial institutions, where the exposure of sensitive data and transactional information can lead to severe consequences.
The absence of software vulnerability exploitation indicates a preference for gaining entry through weaker security controls, such as poorly managed credentials, phishing, or insider threats. This points to a need for financial institutions to invest heavily in user education, robust access management, and continuous network monitoring.
Evasion tactics such as using stolen digital signatures to sign malware exemplify an advanced level of operational security, suggesting the threat actors behind CL-CRI-1014 have significant resources or connections. This also complicates the detection and response process for cybersecurity teams.
Finally, the campaign underscores the importance of proactive threat intelligence and collaboration within the African financial sector. Sharing insights about such threats enables organizations to better anticipate attacker behaviors, strengthen their defenses, and reduce the risk of financial losses.

📊 Prediction: What’s Next for African Financial Cybersecurity?
As cybercriminal groups like CL-CRI-1014 continue to refine their tactics, the African financial sector is likely to see an increase in targeted attacks that combine social engineering with the use of sophisticated but accessible hacking tools. Organizations that rely on traditional perimeter defenses and signature-based detection will remain vulnerable to these stealthy intrusion methods.
The trend toward commoditizing initial access means financial institutions will need to adopt more layered security models, emphasizing zero-trust principles, multifactor authentication, and real-time behavioral monitoring. Collaboration between industry players and security researchers will become even more critical to quickly identify and mitigate emerging threats.
In addition, regulators may impose stricter cybersecurity standards and reporting requirements to safeguard financial ecosystems. This could lead to increased investment in cyber resilience technologies and training, ultimately raising the baseline security posture across the continent.
In the near future, expect the attackers behind CL-CRI-1014 and similar groups to expand their operations, potentially targeting other critical infrastructure sectors beyond finance. Enhanced threat intelligence sharing and adoption of advanced detection tools will be key factors in containing this growing menace.
