Digital Encode Limited, a leading information security and governance, risk, and compliance (GRC) advisory firm, has issued an urgent cybersecurity advisory following a sharp surge in data breaches across Nigeria.
These attacks, according to the firm, have hit financial institutions, government agencies, fintechs, and other major organizations, leaving private and public data exposed.
While a spike in cyber incidents often conjures images of highly sophisticated, Hollywood-style hackers deploying unfixable zero-day exploits, Digital Encode’s advisory reveals a much more frustrating reality: most recent breaches are entirely preventable.
According to the firm, cybercriminals are simply walking through digital doors left unlocked by basic operational oversights.
The advisory, signed by Professor Obadare Adewale Peter, Chief Visionary Officer of Digital Encode Limited, underscores a troubling pattern, where attackers aren’t breaking down reinforced digital walls; instead, they are exploiting misconfigured systems and publicly exposed assets.
These vulnerabilities are easily discoverable using standard cloud indexing tools, open repositories, and dark web marketplaces.
“Organizations affected in recent breaches were not compromised due to highly advanced attacks, but due to lapses in enforcing existing security controls,” Prof. Obadare said.
The firm emphasizes that this is not a technology problem, but an execution gap, a critical disconnect between an organization’s stated security policies and its actual day-to-day implementation.
Digital Encode’s advisory highlights a widespread recurrence of these exposure patterns, particularly across financial institutions, payment service providers, fintech companies, and public sector platforms.
The primary culprits behind the recent wave of breaches include sensitive customer and operational data left exposed in unsecured databases and open cloud buckets and API keys, tokens, and passwords hardcoded directly into web and mobile applications, deployment artifacts, or public repositories.
Others are administrative endpoints, API documentation, and active development environments left open to the internet, unauthorized use of developer-friendly hosting platforms like Vercel, Netlify, and Render by employees, which create blind spots for security teams and an over-reliance on single authentication layers, poor token lifecycle management, and a lack of rigorous third-party vendor risk management.
Prof. Obadare reiterated that basic hygiene, such as ensuring no cloud resources (AWS S3, Azure Blob, Google Cloud, or Firebase) allow anonymous access, and enforcing strict authentication on all APIs would completely neutralize these attack vectors.
To stem the tide of ongoing breaches, Digital Encode has called on organizations across Nigeria to move away from reactive damage control and immediately implement several proactive measures.
First, organizations must conduct a comprehensive audit of all internet-facing assets, including those managed by third-party vendors. They also need to gain clear visibility into “Shadow IT” and any unauthorized platform deployments tied to employee accounts. Furthermore, companies must immediately revoke and rotate all exposed or potentially compromised credentials, passwords, API keys, and tokens. It is equally critical to fix identified system and cloud misconfigurations while independently validating that those fixes actually work.
Finally, organizations should review historical logs to assess whether exposed assets have already been exploited by malicious actors, strengthen their continuous monitoring, logging, and threat detection systems, and document all remediation steps and residual risks to ensure proper governance and regulatory compliance.
As the evolving threat landscape puts more pressure on Nigerian digital infrastructure, Digital Encode reiterated its commitment to supporting organizations through enterprise-wide security assessments and independent validation of their technical controls.
“We strongly advise that this advisory be actioned without delay,” Prof. Obadare warned. Ultimately, the firm’s message is clear: an organization’s resilience against modern cyber threats will not be determined by how much money they spend on complex security tools, but by how effectively they practice basic digital hygiene.
