Africa’s next major security crisis may not begin with a military invasion, terrorist attack or coup. It could begin with a cyberattack against an electricity grid, the disruption of banking systems, sabotage of telecommunications infrastructure or a coordinated disinformation campaign designed to destabilise a government.
These are potential instruments of grey-zone warfare, a form of strategic competition conducted below the threshold of conventional armed conflict. For African governments already confronting insurgencies, organised crime, political instability and economic insecurity, hybrid threats introduce another dimension of vulnerability. The danger is that states may experience simultaneous disruptions without recognising that seemingly unrelated incidents form part of a coordinated campaign.
Modern national security must therefore extend beyond protecting borders and defeating armed groups. It must also protect the economic, technological and institutional systems upon which national stability depends.
Understanding Grey-Zone warfare
Grey-zone warfare operates between ordinary geopolitical competition and open military confrontation. Its purpose is to influence political decisions, weaken institutions or gain strategic advantages without provoking conventional military retaliation. Hybrid warfare combines different instruments, including cyberattacks, disinformation, economic coercion, sabotage, proxy forces and covert political interference.
The distinction is important because not every infrastructure failure, protest or financial disruption constitutes hostile activity. An electricity blackout may result from poor maintenance. Demonstrations may reflect legitimate public grievances. Banking failures may originate from technical problems. However, when several disruptions are deliberately coordinated to pressure a government, they may represent a wider strategic operation.
For Africa, distinguishing genuine hybrid threats from ordinary governance failures is essential. Misidentifying domestic opposition as foreign interference could itself undermine democratic stability.
Disinformation as a strategic weapon
Information manipulation has become one of the cheapest instruments of modern geopolitical competition. Social media allows fabricated reports, manipulated videos and coordinated narratives to circulate rapidly across national borders.
During elections, disinformation can undermine confidence in electoral institutions, inflame ethnic tensions or portray political opponents as agents of foreign governments. In conflict zones, competing information campaigns can exaggerate military victories, conceal defeats and influence public attitudes towards armed groups.
The African Centre for Strategic Studies has documented foreign-sponsored disinformation campaigns across the continent, demonstrating how information operations have become intertwined with geopolitical competition. However, disinformation rarely succeeds in isolation.
It exploits existing frustrations involving corruption, unemployment, insecurity and distrust of political institutions. Governments therefore cannot defeat hostile narratives through censorship alone. Credible communication, independent journalism, digital investigation and accountable institutions remain essential.
Cyberattacks against critical infrastructure
Africa’s expanding digital economy creates opportunities alongside new security vulnerabilities. Electricity networks, telecommunications systems, airports, ports, hospitals and financial institutions increasingly depend upon interconnected digital infrastructure. A successful cyberattack against one system could disrupt several others.
Consider Nigeria’s banking sector. A coordinated attack against major payment infrastructure could interrupt salaries, commercial transactions and essential services without a single conventional weapon being deployed. Similarly, interference with port-management systems could delay cargo clearance, increase import costs and disrupt industrial supply chains.
Cybersecurity must therefore become a national-security responsibility rather than remain exclusively an information-technology function. Military cyber units, intelligence agencies, financial regulators and private infrastructure operators need mechanisms for exchanging threat intelligence and coordinating responses.
Economic coercion and strategic dependence
Hybrid pressure can also exploit economic vulnerabilities. Restrictions affecting international payments, shipping insurance, technology transfers, investment or critical supplies can impose significant costs upon targeted states.
Economic sanctions are not automatically acts of warfare. Nevertheless, financial dependence can provide external powers with considerable leverage during geopolitical confrontation. African countries remain heavily dependent upon imported military equipment, foreign technology, international financing and external maintenance arrangements.
A government unable to obtain aircraft components or access essential software because of foreign restrictions may discover that strategic dependence has direct security consequences. This strengthens the case for diversified partnerships, domestic industrial capabilities and regional financial infrastructure.
Strategic autonomy does not require economic isolation. It requires credible alternatives when international relationships deteriorate.
Proxy forces and plausible deniability
Africa’s fragmented security environment creates opportunities for indirect intervention. Militias, private military companies, criminal organisations and armed movements can sometimes advance the interests of external actors without operating as conventional state forces.
Such arrangements may allow sponsors to influence events while denying direct responsibility. Weak borders, illicit arms markets and contested territories can make these relationships difficult to investigate. However, the existence of an insurgency does not automatically establish foreign sponsorship.
Reliable intelligence, financial investigations and evidence of operational coordination are necessary before attributing armed violence to external governments. The strategic challenge is identifying genuine proxy relationships without reducing complex African conflicts to simplistic foreign conspiracies.
Maritime and energy infrastructure
Africa’s maritime economy presents another potential grey-zone battlefield. Submarine communications cables, offshore oil installations, pipelines, ports and shipping corridors are essential to national economic security.
Disruption to these systems could affect several countries simultaneously. The Gulf of Guinea is particularly important because of its offshore energy resources, commercial ports and shipping connections. Meanwhile, instability around the Red Sea and Bab el-Mandeb demonstrates how threats to maritime commerce can increase freight costs, insurance premiums and supply-chain uncertainty.
African naval strategy must consequently extend beyond conventional patrols. Protecting underwater infrastructure, port technology, offshore facilities and maritime communications should become increasingly important defence responsibilities.
Why Nigeria is particularly vulnerable
Nigeria combines several characteristics that make hybrid threats strategically significant. Its large population, influential media environment, extensive banking sector, energy infrastructure and politically diverse society create multiple potential targets.
A coordinated campaign could exploit communal tensions, manipulate electoral information, disrupt digital financial services or threaten petroleum infrastructure. Nigeria’s security institutions traditionally organise responses around identifiable adversaries such as terrorists, kidnappers, insurgents and organised criminal networks.
Grey-zone warfare challenges this model because attackers may operate through anonymous digital accounts, financial intermediaries, criminal hackers and covert influence networks. Effective defence consequently requires cooperation between the armed forces, intelligence services, police, telecommunications regulators, financial institutions and civilian authorities.
No single agency can independently address every dimension.
Building Africa’s hybrid defence architecture
African governments need security systems capable of recognising threats that cross institutional boundaries. The African Union and regional organisations should strengthen intelligence-sharing arrangements, cyber incident response and protection of critical infrastructure.
National security councils should regularly simulate simultaneous disruptions affecting electricity, communications, banking and transport. Such exercises would reveal institutional weaknesses before adversaries exploit them.
Governments should also develop credible attribution procedures and transparent public communication strategies. Protecting national security must not become an excuse for suppressing independent journalism, peaceful protest or legitimate political opposition.
Public trust is itself an important component of national resilience.
National security beyond the battlefield
The defining characteristic of grey-zone warfare is that an adversary may weaken a country without defeating its armed forces. A government can retain territorial control while losing financial stability, communications capability, public confidence or freedom of strategic decision-making.
For BusinessDay readers, the central lesson is that African defence planning must move beyond barracks, borders and conventional weapons. Electricity, banking, telecommunications, ports, digital information and democratic institutions are now integral components of national security.
Africa must develop the capacity to detect coordinated interference, withstand disruption and restore essential services without surrendering strategic independence. The next major attack against an African state may not announce itself as war. It may arrive disguised as an ordinary crisis, with its strategic purpose becoming apparent only after considerable damage has occurred.
Understanding and preparing for grey-zone warfare is therefore becoming essential to Africa’s security, economic resilience and sovereignty.
