Global cyber threats escalating beyond control — Expert

Cybersecurity researcher, Joy Nnenna Okolo, has expressed concerns over what she described as a fast-intensifying wave of global cyber threats, warning that recent academic findings produced by her and her co-authors show that the world is dangerously unprepared for the scale of emerging digital attacks targeting financial technology systems, organisational networks, and billions of Internet-connected devices.

Okolo, who spoke with our correspondent on behalf of the research teams behind three published peer-reviewed cybersecurity papers, said the studies collectively expose a troubling rise in sophisticated attacks, widening security gaps, and weak institutional response capabilities across critical digital infrastructures.

According to her, the findings present a clear indication that cybercriminals are becoming far more organised and technologically advanced than the systems meant to defend against them.

She explained that the research outputs span three major areas of modern cybersecurity, fintech vulnerabilities, machine-learning-driven privacy risks, and the structural weaknesses of incident response units.

Okolo warned that the insights from all three studies point to one urgent reality: without immediate reforms, digital systems across the world stand at risk of severe disruption.

“From our research, it is obvious that the cyber threat landscape is already beyond what many institutions can manage.

“Across financial platforms, digital payment ecosystems, Internet-connected devices, and corporate networks, attackers are now using artificial intelligence, exploiting APIs, breaching cloud infrastructures, and manipulating machine-learning models. The level of sophistication we documented demands urgent attention,” she said.

Okolo said one of the studies focusing on the global fintech ecosystem found that digital banks, blockchain payment channels, API-driven applications, and automated lending systems are being heavily targeted due to rapid technological expansion that is not matched with adequate cybersecurity investment or regulatory enforcement.

She stated, “The fintech space is growing fast, but the security frameworks are not growing at the same speed.

“Our findings show rising fraud, identity theft, data breaches, API exploitation, and ransomware targeting fintech companies. This is a major threat to financial stability, especially in developing economies.”

She warned that global regulatory fragmentation, where countries adopt different cybersecurity and data-protection laws, has created unsafe gaps that criminals are exploiting.

Okolo added that many fintech startups lack strong compliance structures, making them soft targets for coordinated cyberattacks.

Another study led by her examined the weaknesses in Internet-connected devices and found that billions of IoT and IoD systems used in homes, hospitals, industries, and public infrastructure are now carrying huge volumes of sensitive data that remain exposed to intrusions, manipulation, or interception.

“Most users do not realise how much personal information their devices collect and transmit without active input.

“We found that many machine-learning and deep-learning models powering these devices can be attacked or poisoned, leading to privacy leaks and system compromises. This poses serious risks for eHealth platforms, smart cities, driverless vehicles, and industrial automation,” Okolo explained.

She emphasised that large-scale data leaks, device hijacking, and algorithm manipulation are no longer hypothetical risks but daily realities that governments and private operators must prioritise.

The third study she co-authored investigated incident response models across industries and uncovered significant weaknesses in how organisations detect, contain, and recover from cyber-attacks.

According to her, many institutions still treat incident response as an optional technical function rather than a strategic defence mechanism.

She added, “Our assessment across Security Operations Centres showed that many organisations have uncoordinated teams, poorly integrated security and response departments, and inadequate training practices.

“When attacks occur, delays in detection and response give hackers more time to inflict damage, steal data, and shut down systems.”

She noted that the research recommends integrating security management with incident response teams, strengthening training frequency, improving tooling, and fostering organisational learning to adapt quickly to emerging threats.

Okolo said the combined outcomes of the three studies should trigger deep concern among governments, regulators, financial institutions, and technology firms.

She warned that cybercriminals are now deploying artificial intelligence, deepfake tools, automation and advanced malware strains capable of bypassing traditional security mechanisms.

“We cannot afford a reactive approach anymore. Cybersecurity is now central to economic development, public safety, and national security. The threats are evolving faster than our defences, and if we don’t move quickly, the consequences will be catastrophic,” she said.

She called for stronger cross-border cooperation, better enforcement of cybersecurity regulations, investment in privacy-preserving AI technologies, and widespread digital literacy to help individuals and institutions recognise threats early.

Okolo stressed, “What these studies reveal is that the world is running out of time.

“We need coordinated global action. We need better systems. We need stronger institutions. Cybersecurity can no longer be treated as an afterthought. It is a survival requirement.”
