Introduction: Africa’s Financial Sector Faces a New Cyber Threat
A wave of cyber attacks has been sweeping across Africa’s financial sector since July 2023, drawing serious concern among global cybersecurity experts. The attacks, traced by Palo Alto Networks’ Unit 42 under the codename CL-CRI-1014, use a calculated blend of open-source tools and publicly available resources to breach networks, maintain access, and sell entry points to other threat actors. This reflects a growing trend where Initial Access Brokers (IABs) are facilitating deeper, more damaging cyber intrusions. This article breaks down the tactics, techniques, and implications of this evolving threat landscape targeting Africa’s financial ecosystem.
the Original Report
Palo Alto Networks Unit 42 has identified a sophisticated campaign—labeled CL-CRI-1014—targeting financial institutions across Africa. The campaign, active since at least July 2023, demonstrates a strategic effort by threat actors to gain initial access into networks and later sell that access to other cybercriminals, operating under the model of Initial Access Brokers (IABs).
The attackers utilize open-source tools, including PoshC2 for command and control (C2), Chisel for tunneling malicious traffic, and Classroom Spy for remote access. Their entry methods remain unclear, but once they gain a foothold, they deploy tools in a multi-stage attack chain—starting with MeshCentral Agent and progressing to Classroom Spy and Chisel, before spreading PoshC2 across compromised systems.
To avoid detection, the attackers cleverly disguise malicious payloads using familiar icons from legitimate platforms like Microsoft Teams, Palo Alto Cortex, and VMware Tools. Persistence is maintained through methods such as registering malicious services, adding shortcut files in startup folders, and scheduling tasks under names like “Palo Alto Cortex Services”.
In some attacks, user credentials were stolen and used to configure PoshC2 as a proxy, enabling stealthy communications with C2 servers. Researchers noted these implants were often customized to fit the specific environment being targeted.
This is not the first sighting of PoshC2 in African campaigns. Similar tools were previously seen in the DangerousSavanna spear-phishing attack in 2022, which hit financial and insurance sectors in countries like Morocco, Senegal, Togo, and Cameroon.
Meanwhile, a separate development involves a new ransomware group named Dire Wolf, which has already targeted 16 victims across regions including the U.S., India, and Australia. Written in Golang, the Dire Wolf ransomware has the ability to disable system logs, terminate critical services, and delete shadow copies, preventing data recovery.
While the techniques used by Dire Wolf to gain initial access are still unclear, experts warn organizations to bolster their security hygiene and monitoring to stay ahead of such advanced threats.
What Undercode Say: Cybercrime in Africa’s Financial Sector
Rise of Initial Access Brokers (IABs)
The emergence of CL-CRI-1014 exemplifies the rapid evolution of IABs, who specialize in breaching systems only to sell access to more sophisticated actors. These brokers reduce the technical burden for ransomware groups and other cybercriminals, effectively industrializing cybercrime.
Leveraging Open-Source Tools
The reliance on PoshC2, Chisel, and Classroom Spy indicates a trend towards low-cost, high-impact attacks. These tools are not only free and powerful but also difficult to detect, as they often mimic legitimate administrative behavior. Chisel, for instance, creates covert channels to exfiltrate data and control systems behind firewalls.
Identity Masking and File Spoofing
Disguising malware as trusted applications—such as Microsoft Teams—points to a growing level of social engineering and technical sophistication. By mimicking file signatures and icons, attackers significantly lower the chances of raising suspicion among IT staff.
Multi-Stage Persistence
The use of multiple persistence mechanisms—including scheduled tasks and startup folder exploits—demonstrates a thorough understanding of Windows OS internals. Attackers are ensuring longevity in compromised environments by layering their foothold.
Regional Focus with Global Implications
Although CL-CRI-1014 is focused on Africa, the tactics mirror global campaigns, signaling that the region is no longer a low-priority cyber target. Financial institutions in Africa are now seen as viable and lucrative victims, underscoring the urgent need for region-specific cyber resilience strategies.
Dire Wolf: A Parallel Threat
The sudden rise of Dire Wolf ransomware hints at a broader pattern of global cyber warfare targeting high-value industries. Although unrelated to CL-CRI-1014, Dire Wolf’s technical design shows a shared mindset: speed, stealth, and destruction. Its Golang foundation makes it cross-platform, while its service termination capabilities make recovery almost impossible.
Urgent Need for Detection & Response
Organizations must enhance endpoint detection and response (EDR), invest in real-time threat intelligence, and prioritize user behavior analytics (UBA) to detect anomalies early. Staff training remains essential, especially as threat actors increasingly spoof familiar software to trick users.
✅ Fact Checker Results
- Fact: PoshC2 is widely used in both targeted attacks and red team operations — ✅
- Fact: Disguising malware using trusted software icons is a known tactic used in various campaigns — ✅
- Fact: Dire Wolf ransomware has been confirmed by Trustwave SpiderLabs and is written in Golang — ✅
🔮 Prediction: What’s Next for African Cybersecurity?
With the rise of campaigns like CL-CRI-1014, Africa’s financial institutions are likely to face increased targeting by IABs and ransomware gangs. Expect more hybrid attacks blending phishing, credential theft, and open-source tooling. We also predict increased cyber defense investments across the region, with a growing market for local SOCs, threat hunting teams, and AI-powered threat detection systems. The regional threat landscape is maturing—and so must its defenses.
