Digital Encode raises alarm over preventable cybersecurity gaps behind Nigeria’s recent data breaches

Digital Encode Limited has warned that many of the cybersecurity incidents recently affecting Nigerian organisations are the result of preventable security failures rather than sophisticated cyberattacks, exposing a critical gap in how institutions implement and manage cybersecurity controls.

The information security and Governance, Risk and Compliance (GRC) advisory firm issued the warning following a surge in cyber breaches impacting financial institutions, fintech companies, government agencies and other organisations across the country.

According to the advisory signed by the Chief Visionary Officer of Digital Encode, Prof. Obadare Adewale Peter, threat actors have increasingly exploited exposed digital assets, weak access controls and poorly configured systems to gain unauthorised access to sensitive information.

The development comes as Nigeria accelerates digital transformation across key sectors, including banking, fintech, e-government services and digital commerce, increasing the importance of robust cybersecurity frameworks.

Digital Encode noted that contrary to popular assumptions, many recent breaches were not driven by advanced zero-day exploits or highly sophisticated hacking tools. Instead, attackers leveraged weaknesses such as publicly accessible cloud storage, exposed databases, leaked credentials, unsecured application programming interfaces (APIs) and poor authentication controls.

“Most of the vulnerabilities we are seeing are basic security hygiene issues that should have been addressed through existing controls and governance processes,” the advisory stated.

The firm identified several recurring exposure points, including hardcoded API keys and authentication tokens embedded in web and mobile applications, cloud resources configured for anonymous access, leaked credentials in software repositories and deployment environments, exposed administrative interfaces and weak internal access management policies.

It also highlighted the growing security risks associated with third-party hosting platforms and inadequate vendor risk management frameworks.

According to cybersecurity experts, these weaknesses are particularly concerning because they are often discoverable through publicly available tools, search engines, code repositories and dark web marketplaces, making them easy targets for cybercriminals.

Prof. Peter stressed that organisations must move beyond compliance-driven cybersecurity strategies and focus on continuous security validation and operational discipline.

“Organisations affected in recent breaches were not compromised due to highly advanced attacks but due to lapses in enforcing existing security controls. Security must be embedded into everyday operational processes, not treated as a one-time compliance exercise,” he said.

The advisory recommends immediate audits of internet-facing assets, rotation of exposed credentials, remediation of cloud misconfigurations, strengthening of monitoring systems and comprehensive reviews of third-party security exposures.

Digital Encode also urged organisations to improve visibility into shadow IT infrastructure and unauthorised deployments, which increasingly create blind spots that attackers exploit.

The warning comes at a time when cybercriminals are adopting more sophisticated techniques powered by artificial intelligence, automation and social engineering. However, experts maintain that basic cybersecurity hygiene remains one of the most effective defences against attacks.

As Nigeria’s digital economy continues to expand, industry analysts say organisations that fail to address foundational cybersecurity weaknesses risk exposing sensitive customer data, disrupting services and undermining trust in digital platforms.

Digital Encode reiterated its commitment to supporting organisations through security assessments, governance advisory services and independent validation of cybersecurity controls, urging both public and private sector institutions to act swiftly before minor security gaps escalate into major breaches.
