The National Information Technology Development Agency (NITDA) has issued a stark warning about a new and dangerous malware, Grandoreiro, which is now targeting African financial institutions and their customers. Originating from Latin America, this sophisticated banking malware is a clear example of how cyber threats are becoming increasingly global and invasive.
What is Grandoreiro?
Grandoreiro is a banking trojan that uses phishing techniques to deceive users into compromising their sensitive financial information. Once activated, the malware:
- Records User Activities: Tracks keystrokes and monitors system interactions.
- Steals Data: Captures banking credentials, account passwords, and PINs.
- Transfers Information: Sends stolen data to cybercriminals, enabling unauthorized access to accounts and potential financial theft.
How Does It Work?
Grandoreiro typically infiltrates systems through phishing emails, malicious links, or fake websites that appear legitimate. Once a user interacts with these deceptive platforms, the malware is deployed, embedding itself within the system. From there, it silently works to:
- Monitor banking sessions.
- Redirect users to fraudulent websites.
- Exploit vulnerabilities in the banking ecosystem.
Cyber Threats in African Banking
The emergence of Grandoreiro in Africa underscores the rising sophistication of cyberattacks targeting the continent’s rapidly digitizing financial sector.
Recent Cybersecurity Incidents:
- Equity Bank Breach (Kenya):
In April 2024, hackers orchestrated a debit card fraud scheme, stealing approximately $1.3 million. This attack exposed vulnerabilities in the bank’s system and highlighted the need for enhanced security measures. - Ghana’s Cybersecurity Alert:
Following a global software failure involving key cybersecurity firms, the Africa Centre for Digital Transformation (ACDT) warned of heightened risks for financial institutions, urging immediate proactive action. - South Africa’s Digital Wallet Phishing:
In June 2024, First National Bank (FNB) reported increased phishing and smishing attacks targeting digital wallet users. These tactics exploit human errors rather than system vulnerabilities, emphasizing the importance of user education.
Internal Fraud Compounds the Challenge
In addition to external cyber threats, internal vulnerabilities remain a pressing concern for African financial institutions. In Q2 2024, Nigerian banks terminated 49 employees for involvement in fraudulent activities, a 40% increase from the previous quarter. Such incidents weaken trust in the banking system and highlight the need for stricter internal controls.
NITDA’s Call to Action
Recognizing the gravity of the situation, NITDA has urged banks to strengthen their cybersecurity defenses. Key recommendations include:
For Financial Institutions:
- Deploy Advanced Threat Detection Systems: Use AI-driven tools to identify and neutralize malware threats in real time.
- Conduct Regular Security Audits: Assess vulnerabilities in systems and processes.
- Train Employees: Equip staff with the knowledge to identify and respond to phishing attempts and other cyber threats.
For Customers:
- Avoid Unsolicited Communications: Do not respond to emails, messages, or calls requesting banking details.
- Verify Authenticity: Confirm the legitimacy of requests directly with financial institutions.
- Monitor Accounts: Regularly check for unauthorized transactions or unusual activity.

Growing Threats to Digital Banking:
As more African banks digitize their services, they become attractive targets for sophisticated cybercriminals. According to recent reports, Africa ranks high in cryptocurrency adoption and mobile banking use, making it a lucrative region for cyberattacks.
Collaborative Defense Strategies:
To combat the escalating threats, a collaborative approach is essential. This involves:
- Regulatory Oversight: Bodies like NITDA and the Central Bank of Nigeria must enforce stringent cybersecurity standards.
- Public-Private Partnerships: Collaboration between governments, financial institutions, and tech firms can drive innovation in security technologies.
- Customer Awareness Campaigns: Educating users about the risks and best practices can reduce human error, a common entry point for cybercriminals.
Conclusion: A Call for Vigilance and Resilience
The rise of Grandoreiro and other advanced cyber threats signals a crucial turning point for Africa’s banking sector. Robust cybersecurity frameworks, proactive defenses, and a well-informed public are key to safeguarding the continent’s financial systems.
NITDA’s warning serves as a timely reminder: the battle against cybercrime requires vigilance at every level—from regulatory bodies and financial institutions to individual customers. By working together, Africa can build a resilient defense against the evolving landscape of digital threats, securing the promise of its growing digital economy.
