The recent revelation of vulnerabilities within the Nigerian financial system has raised serious concerns regarding the state of cybersecurity in startups and fintech businesses. Sennaike David, an experienced information security expert, and bug bounty hacker, has uncovered critical flaws in numerous financial institutions, highlighting the urgent need for immediate action to address these issues.
Widespread Vulnerabilities:
Based on Sennaike David's findings, it is apparent that a vast majority of financial organizations listed on the Wikipedia page of Nigerian banks are susceptible to cybersecurity threats. Approximately 90% of the listed institutions face potential risks due to various vulnerabilities, leaving them open to exploitation by malicious actors.
Exposed Private Data:
During his investigation, Sennaike discovered a dark web post offering the private data of a Nigerian fintech company, including access to servers, usernames and passwords, API keys, and confidential customer information. This revelation underscores the dire security situation faced by these institutions, as sensitive data was readily available for sale on illicit platforms.
Identification of Vulnerabilities:
Sennaike actively engaged with the hackers selling the compromised data, employing complex social engineering techniques to gain access to their servers. Through this process, he obtained insights into the entry vectors employed by these hackers, exposing vulnerabilities that could compromise the security of financial institutions.
Critical Vulnerabilities:
The discovered vulnerabilities range from outdated software and misconfigured systems to poor access controls and exposed sensitive information. Some of the most significant findings include:
a. Exploitable backdoor user in a top 5 bank's Fat-pipe mVPN server, allowing unauthorized access to the internal infrastructure.
b. Exposed internal API keys, passwords, and usernames in the "appsettings.json" file on multiple servers across 11 banks.
c. SQL injection vulnerabilities in approximately 40 banks, providing direct access to databases and compromising server integrity.
d. Default password in an IBM server running Axis2, enabling lateral movement and compromising additional servers.
e. Vulnerable versions of Cisco VPN and Forti IOS in around 70% of banks, potentially compromising VPN user sessions and server content.
f. Exposed log files, directory listings, and leaked passwords on GitHub, exposing critical information and facilitating unauthorized access.
g. Vulnerable Web-logic servers in over 30 banks, posing a significant threat to Internet banking systems.
h. Exploitable default access in a payment company's PRTG server, enabling control over multiple servers.
i. Critical vulnerability in a top 5 bank's Exchange server, allowing unauthorized access to emails and enabling potential BEC scams.
Inadequate Penetration Testing:
The presence of such critical vulnerabilities raises questions about the efficacy of penetration testing conducted by financial institutions. It is imperative to reassess the skills and expertise of professionals engaged in these tests to ensure comprehensive assessments and thorough vulnerability mitigation.
Urgent Call for Action:
To address the cybersecurity shortcomings and protect Nigerian startups and fintech businesses, the following actions are recommended:
a. Engage trained professionals: Financial institutions must employ highly skilled and certified information security experts to conduct comprehensive penetration tests and provide continuous SOC monitoring.
b. Encourage bug bounty programs: Establishing bug bounty programs will incentivize ethical hackers to identify and report vulnerabilities, allowing organizations to proactively address security issues.
c. Collaborate with international platforms: Nigerian companies should explore partnerships with established bug bounty platforms like HackerOne to leverage the expertise of a global community of hackers and strengthen their security measures.
d. Promote regular security updates: Financial institutions must prioritize timely software updates and patches to address known vulnerabilities and reduce the risk of exploitation.
e. Enhance employee training: It is crucial to invest in robust cybersecurity awareness and training programs for all employees within startups and fintech businesses. This will help foster a culture of security and ensure that employees understand their role in protecting sensitive data and identifying potential threats.
f. Implement comprehensive security measures: Startups and fintech businesses should adopt a layered security approach, including strong access controls, regular security audits, network segmentation, encryption, and intrusion detection systems. Regular security assessments and risk management processes should be implemented to identify and address vulnerabilities promptly.
g. Foster collaboration and information sharing: Financial institutions must collaborate, with industry associations, and relevant regulatory bodies to share information and best practices in cybersecurity. This collective effort will help raise awareness, address common threats, and strengthen the overall resilience of the sector.
h. Regulatory oversight and compliance: Regulatory bodies should enforce stringent cybersecurity regulations and standards for startups and fintech businesses. This should include mandatory cybersecurity audits, incident reporting, and penalties for non-compliance. By holding organizations accountable for their security practices, regulatory oversight can help drive improvements and ensure the protection of customer data.
the revelations brought to light by Sennaike David's investigation into the cybersecurity state of Nigerian financial institutions are deeply concerning. The vulnerabilities and loopholes identified within these startups and fintech businesses pose a significant threat to the security and integrity of the entire financial system. Immediate action must be taken to address these issues and mitigate the risks involved.
Startups and fintech businesses must prioritize cybersecurity as a fundamental aspect of their operations. This includes investing in skilled professionals, conducting thorough penetration testing, implementing robust security measures, and fostering a culture of security awareness among employees. Collaboration, information sharing, and regulatory oversight are vital to ensure a comprehensive and effective approach to cybersecurity within the industry.
Failure to address these critical issues could have severe consequences, ranging from unauthorized access to customer accounts and financial data breaches to potential disruptions in the overall stability of the financial ecosystem. The time for complacency is over; proactive measures must be taken to safeguard the sensitive information of customers and protect the reputation and trustworthiness of Nigerian financial institutions.
By heeding these warnings and implementing the necessary security measures, startups and fintech businesses can fortify their defenses against cyber threats and contribute to the development of a secure and resilient financial landscape in Nigeria. The path to a safer future lies in the collective effort of all stakeholders involved – organizations, regulators, and professionals – to prioritize cybersecurity and make it an integral part of their business strategies.
We hope that this wake-up call will catalyze change, prompting a swift and decisive response to the vulnerabilities exposed. Let us work together to build a robust and secure financial ecosystem that instills confidence, protects customer interests, and fosters sustainable growth for startups and fintech businesses in Nigeria.
