The internet in such a short time has become the most pervasive communication system in the world.  Digital statistics show that whilst it took Radio 38 years and TV 13 years to individually reach 50 million users; it took the Internet only 4 years.

Even though the world is increasingly interconnected through mobile, high-speed communications, two thirds of the world’s population have yet to gain access to the Internet (UN Millennium Goals, 2012 Update Report).

Also not debatable is the economic and social impact of the internet.

A study by the World Bank revealed that a 10% increase in broadband penetration can boost the GDP growth of low- and middle-income developing countries by 1.38% — more than any other telecommunication service.

Over the last 20 years, the Internet and the Web have transformed our lives.

Looking forward, we are seeing even more exciting digital developments that will provide more benefits to more people in more places.

Some of the unprecedented opportunities that broadband connectivity presents include:

Citizen – get information/work done anywhere and anytime, also having newer ways for communicating, contributing, acting, and learning.

Businesses – News ways to serve clients and new competitive advantages, new ways to be more productive.

Innovators – New market segments, geographies, business opportunities, and competitiveness regardless of size.

Government – News ways to serve citizens and businesses, address core societal issues (Education, Healthcare, Environment etcetera), and provide Infrastructure for innovation/research leading to creation of more jobs (SMEs)

The internet has become so central to our existence in this age that the UN, defined access to the Internet as now among one of global citizens’ most basic rights.

The European Commission’s Digital Agenda goes one step further by similarly highlighting broadband access as a basic right.

Invariably connectivity (interchangeably here Spectrum) is essential in the same sense as oxygen: invisible and unnoticed, until you don’t have it (and by then you are dead).

It is therefore sad that today most of the world’s population is unconnected.

The International Telecommunications Union (ITU) estimates that for over 3.9 billion people, around 61% of the world’s population, the price of fixed broadband is unaffordable.

By continent this ranges from 8% of the population of Europe, to 90% of the population of Africa.

Likewise, basic mobile broadband is unaffordable for over 2.6 billion of the world’s population.

On the flip side the need for persistent connectivity is fueling innovation and consequentially proliferation of devices – it is expected that by 2020 there will be more than 100 billion connected intelligent devices globally.

And of course the vast majority of this connection is relying on wireless technologies and the currency of the wireless industry is Spectrum; literally the oxygen of the digital world.

Spectrum describes the range of frequencies, which wireless devices can use to transmit and receive information.

In order to manage access to spectrum, regulators allocate different bands of frequencies for different uses and establish technical rules to minimize the likelihood of harmful interference. Some bands of spectrum are licensed for the exclusive use of certain entities and specified purposes.

These include uses as varied as military and public safety purposes as well as commercial applications such as radio, television and broadband Internet.

Other bands are set aside for shared use on an unlicensed or license-exempt basis. Common uses of unlicensed or license-exempt spectrum today are Wi-Fi networks and Bluetooth devices.

It is relevant to note that historically, spectrum was managed by assigning exclusive rights to use a specific frequency in a specific location.

Initially, these authorizations were granted to governmental and commercial users at no cost. Since last two decades however, long term commercial licenses have generally been assigned through competitive auctions.

Winning bidders typically receive spectrum access in the form of exclusive assignments of frequencies to chosen services (i.e., licenses), ensuring that no other services infringe on that assignment (i.e., no interference).

 Obviously limited by technology signal interference were considered a major problem of spectrum which ultimately drove the way spectrum management were therefore conceptualize, create blocks of delineated bands that guarantees exclusive use and protection of licensees’ signals.

The problem however is that this traditional licensing model of spectrum bands has limited the amount of usable spectrum for wireless data communications, particularly as the demand for data, voice, and video traffic continues to explode on Internet enabled mobile devices.

To obtain more spectrum for these applications, regulators around the world are considering proposals to assign more spectrum for exclusive use licensing.

However, nearly all the RF spectrum is allocated for specific applications, making reallocation of exclusive use licenses extremely challenging and time consuming.

In reality, large portions of the allocated spectrum are not actively used in space and time.

To alleviate this disparity in spectrum use, researchers and policy makers have proposed the concept of Dynamic Spectrum Access (DSA), allowing devices to use unoccupied portions of spectrum without interfering with the licensee’s transmissions

Dynamic Spectrum Access (DSA) is an umbrella term used to describe a set of technologies and techniques enabling radio communications devices to opportunistically transmit on available radio spectrum.

These technologies and techniques ensure that consumers and their devices have wireless bandwidth when and where they need it.

We at Microsoft belief that the first globally-harmonized opportunity to use DSA technologies and techniques will be in the TV bands.

Technologies exist today that can use TV band white spaces spectrum for a range of wireless applications, from broadband, to wireless offload, to machine-to-machine.

The term TV White Space spectrum refers to frequencies in the VHF and UHF television broadcast bands that are either unassigned or unused by existing broadcast or other licensees.

Television broadcasts occupy designated channels in the VHF and UHF bands, with the assignment of channels to broadcasts varying by location.

Not all the designated channels are in use for broadcast in any given market, giving rise to “White Spaces” in which a channel that is not used for broadcast may be available for other purposes.

Unlocking the TV band and other unused white spaces spectrum will mean significantly increasing the total amount of bandwidth available for consumers and their devices – and thereby alleviating pressure on other spectrum bands.

Based on the results of trials Microsoft has conducted in the U.S, Europe and Asia, we believe that TVWS technology will be able to deliver similar functionality and high speeds compared to other wireless broadband technologies.

TVWS has couple of distinct advantages highlighted below:

TVWS networks work in much the same way as conventional Wi-Fi, but the signals travel over longer distances than the typical Wi-Fi signal.

Conventional Wi-Fi is relatively weak when it comes to working in typical physical settings – bumping up against concrete obstructions and many types of walls. TVWS can overcome these limits.

Just as your TV signal passes through walls (and many of them), the wireless signal for your Internet connection will as well.

Ability to achieve greater efficiencies

Covering a longer and wider range with approximately the – same power and computing requirements results in systems – that will deliver more bandwidth and more consumer benefits at lower network costs and lower power consumption.

Given these inherent distinct advantages, some specific scenario that TVWS easily lends itself to as a best in class solution include:

Leveraging long range characteristics enables scenarios like Cellular offloading; Rural broadband/backhaul; Wide-coverage hotspots; Sensor network; Wireless surveillance system; etc.

Whilst its obstacle penetration/avoidance characteristics enables Indoor video distribution; M2M –factory floor automation; Device to device network; etc.

For over 5 years, Microsoft has been working with industry and government partners around the world to demonstrate the viability and potential of Dynamic Spectrum and TV White Spaces.

The viability of the technology has been proven in over a dozen trials and commercial deployments around the world – ranging from remote villages of Africa to the dense urban centers of Asia.

As part of efforts to drive thought leadership in this space, Microsoft recently partnered with couple of other stakeholders to form the Dynamic Spectrum Alliance; a global, cross-industry alliance focused on increasing dynamic access to unused radio frequencies.

DSA is advocating for laws and regulations that will lead to more efficient and effective spectrum utilization.

Its membership spans multinationals, small- and medium-sized enterprises, and academic, research, and other organizations from around the world, all working to create innovative solutions that will increase the amount of available spectrum to the benefit of consumers and businesses alike.

Specific goals of DSA includes:

Closing the Digital Divide –supporting technical, regulatory, and business model innovations that can reduce the cost of deploying last-mile wireless networks and help to make wireless broadband access more affordable for people around the world.

Enabling the Internet of Things – supporting spectrum policies that can enable the burgeoning Internet of Things – with potentially billions of interconnected wireless devices operating on our behalf – increasing efficiency and improving quality of life.

Alleviating the “Spectrum Crunch” – The Dynamic Spectrum Alliance supports changing regulatory policies that create artificial spectrum scarcity and replace them with policies that will increase available bandwidth, reduce costs, and increase consumer choice.

In Nigeria we are at the fore-front of advocacy for the use of TVWS to help actualize the goals of the countries recently released well-articulated Broadband Policy Implementation Plan.

Amongst other broad goals, the broadband plans has a target to deliver 80% mobile broadband penetration by 2018 and an open access shared infrastructure environment to support future growth. 

Microsoft is keen to with local partners participate in a TV band white spaces regulatory trials to explore large scale pilot that addresses scenarios of Education, eHealth, Rural Digital Inclusion, etc.

In conclusion, TVWS will enable new business models making access more affordable and can improve education, healthcare, e-government, small business empowerment & social inclusion; for this to materialize policymakers should think differently about spectrum allocation and regulation.

We support ongoing efforts to gain a better understanding of the viability and potential impact of TVWS in Nigeria by the Ministry of Communication Technology and the Federal Spectrum Management Council through ongoing discussions around regulatory trials and demonstration in the country.

We further recommend that TVWS ultimately be made available for license-exempt (unlicensed) access on a harmonized basis, facilitated by the use of geo-location databases and other interference protection mechanisms to support the Nations objectives of enabling ubiquitous affordable broadband connectivity and services across Nigeria country to better position the country to compete in the information age.

Computer Professionals (Registration Council of Nigeria), also known as CPN has begun a nationwide crackdown on quackery and unlicensed practices in a bid to strengthen professional standards in the country’s information technology sector.

CPN Begins Crackdown on Quack IT Professionals, Vows Tougher Action against Cybercrime

CPN has also  vowed tougher action against cybercrime in the country.

These were the major decisions taken at its 2026 Information Technology Professionals’ Assembly and Annual General Meeting (AGM) on Friday

Essien Eyo, president and chairman of Council of CPN, speaking at a virtual press conference, said the council would continue to enforce strict compliance with professional regulations to safeguard the integrity of Nigeria’s computing ecosystem.

He warned that the council would not tolerate unlicensed practice in the sector, stressing that regulatory enforcement would be strengthened in line with its statutory mandate.

“The Act makes it mandatory for all persons and organisations seeking to engage in computing and professional services to be registered and licensed by the council.

“It is illegal to engage in computing and professional practice without satisfying the requirement of registration and possession of a valid licence,” Eyo said.

He added that the council was determined to rid the sector of quackery and ensure that only qualified professionals are allowed to operate.

“CPN is committed to ensuring high professional ethics and standards, and we will continue to intensify efforts to eliminate quackery, arbitrary practice and lack of standards in the IT sector,” he stated.

Eyo disclosed that the 2026 IT Professionals’ Assembly, scheduled for May 13 and 14 at the NAF Conference Centre, Kado, Abuja, would serve as a key platform to advance regulatory compliance, professional development and industry collaboration.

The event, now in its 20th edition, has the theme, “Digital Resilience and Inclusion for Smart Economy,” and aligns with Nigeria’s broader digital economy and Renewed Hope Agenda.

He explained that the theme reflects the urgent need to build a secure, inclusive and resilient digital ecosystem capable of withstanding modern technological disruptions.

“In an era defined by rapid technological change, cybersecurity threats, economic disruptions and evolving digital demands, resilience ensures that digital infrastructure and institutions can withstand shocks and sustain growth,” Eyo said.

“At the same time, inclusion guarantees that no segment of society is left behind in accessing digital opportunities.”

He said the assembly would also focus on emerging digital risks, ethical technology deployment, inclusive policy frameworks and strengthening collaboration among government, industry, academia and civil society.

Eyo further noted that the event would feature the induction of new members into the computing profession and would be delivered in a hybrid format to ensure wider participation.

“The 2026 IT Professionals’ Assembly is not just an event but a strategic platform for shaping Nigeria’s digital destiny,” he said.

He confirmed that the keynote address would be delivered by Bosun Tijani, minister of Communications, Innovation and Digital Economy.

Also speaking,  Aliu Abdullahi, vice president of Council, said the establishment of CPN was a Federal Government response to the need for proper regulation of Nigeria’s growing IT sector.

He said the council’s mandate includes setting professional standards, accrediting academic programmes, conducting examinations, regulating practice, enforcing ethics and maintaining the national register of computing professionals.

Abdullahi reiterated that all individuals and organisations engaged in IT training, computing services and related activities must be duly registered and licensed by the council.

He urged media organisations to support public awareness of the council’s activities, especially the forthcoming assembly, which he described as critical to strengthening Nigeria’s digital governance and professional integrity.

Surfshark, a Netherlands-based cybersecurity firm, has reported that Nigeria recorded about 24.1 million compromised user accounts since 2004, making it the third most affected country in Sub-Saharan Africa.

Nigeria Hit by 24.1m Data Breaches - Surfshark

The report, which analysed global data breach trends for the first quarter of 2026, showed that Nigeria recorded 281,500 leaked accounts between January and March 2026, ranking the country as the 34th most breached nation globally during the period.

Globally, the report revealed that 210.3 million accounts were breached in the first quarter of 2026, representing a sharp increase compared to previous periods.

The United States accounted for 29 per cent of all reported breaches worldwide, followed by France, India, Brazil and the United Kingdom.

According to the report, cyber threats targeting Nigerian users have continued to intensify over the years, exposing millions of individuals to risks such as identity theft, account hijacking, extortion and financial fraud.

Surfshark disclosed that about 7.5 million unique email addresses linked to Nigerian users have been exposed since 2004, while approximately 13 million passwords were leaked alongside compromised accounts.

The report noted that more than half of breached Nigerian users remain vulnerable to cyber-related crimes.

“Statistically, 10 out of 100 Nigerian people have been affected by data breaches,” the report stated.

Further analysis showed that leaked data linked to Nigerian users included highly sensitive information such as Social Security-related records, payment card details, residential addresses, and personal contact information.

According to the report, about 3,900 Social Security-related records and 1,600 payment card details were exposed, alongside 1.9 million phone numbers and more than 925,000 residential addresses.

The cybersecurity firm warned that the growing scale of data exposure reflects increasing vulnerabilities in the global digital ecosystem as businesses accelerate the adoption of artificial intelligence technologies.

Commenting on the trend, Tomas Stamulis, chief security officer, Surfshark, said the rapid integration of AI systems by companies has significantly expanded the volume of user data being collected and stored.

According to him, businesses are increasingly relying on AI-driven tools for automation, analytics and operational efficiency, leading to the accumulation of larger datasets that could become attractive targets for cybercriminals.

The report cited industry statistics indicating that 20.2 per cent of companies used AI technologies in 2025, up from 8.7 per cent in 2023.

“These AI-driven systems collect and log more detailed user information for automation, analytics, and model improvement,” Stamulis said.

He added that while artificial intelligence improves productivity and operational efficiency, it also increases the number of systems organisations must secure, thereby creating additional opportunities for cyberattacks and data leaks.

Stamulis further warned that compromised personal information often retains value for cybercriminals long after passwords or email credentials have been changed.

According to him, hackers frequently combine old and newly leaked information into so-called “combo lists,” which are repeatedly traded or deployed for fraudulent activities and identity theft schemes.

He advised internet users to minimise the amount of sensitive personal information shared online, use alternative email identities or masking services where possible, and provide confidential information only when necessary.

The report also showed that global breached accounts in the first quarter of 2026 tripled compared to the corresponding period of 2025 and rose by 22 per cent relative to the fourth quarter of 2025, underscoring the growing sophistication and frequency of cyberattacks worldwide.

National Information Technology Development Agency (NITDA), has raised alarm over a new artificial intelligence-powered malware known as “DeepLoad,” warning that the cyber threat is actively targeting Nigerian government agencies, financial institutions, businesses and individuals.

NITDA Warns of  AI-Powered DeepLoad Malware Targeting Banks, Govt Agencies

The agency disclosed this in a critical advisory issued through its Computer Emergency Readiness and Response Team (CERRT.NG) and shared via its official X account.

The warning comes amid a growing wave of cyber-attacks targeting Nigerian organisations, including private institutions such as banks and government agencies like the Corporate Affairs Commission (CAC).

According to NITDA, DeepLoad is an AI-enhanced malware strain designed to infiltrate systems, steal sensitive information and evade conventional antivirus detection systems.

“The malware is distributed through a social engineering technique involving fake website error,” the advisory stated.

NITDA explained that the malware spreads through deceptive website prompts that trick users into executing malicious commands on their computers.

“Once executed, DeepLoad silently installs itself, harvests stored credentials and sensitive data from major browsers, and leverages artificial intelligence to evade antivirus detection,” the agency said.

The agency further warned that one of the most dangerous features of the malware is its ability to remain active even after attempted removal.

“Critically, the malware incorporates a hidden WMI-based persistence mechanism capable of reactivating the infection up to three days after apparent removal,” it stated.

NITDA stressed that the severity of the threat requires immediate action from both organisations and individuals across the country.

“Given its severity and confirmed active targeting of Nigerian entities, all organizations and individuals must implement the protective measures outlined in this advisory immediately,” the agency added.

The agency warned that individuals, government institutions, businesses, large organisations and small enterprises are all vulnerable to the rapidly evolving cyber threat posed by DeepLoad.

According to NITDA, a successful DeepLoad infection could grant cybercriminals unauthorised access to bank accounts, mobile money services and payment cards, while also enabling the theft of passwords, documents and sensitive personal information stored on web browsers.

The agency warned that the stolen information could be exploited for identity fraud, allowing criminals to impersonate victims for financial gain.

For organisations, NITDA said infections could trigger operational disruptions requiring complete system isolation and remediation procedures. It added that attacks on government systems could compromise classified networks and pose broader national security risks.

To prevent infections, NITDA advised Nigerians never to paste commands from websites into their computers, noting that legitimate software providers do not request such actions.

The agency also cautioned users against opening suspicious files such as “Chrome Setup” or “Firefox Installer” from USB drives and advised that all external storage devices be scanned with antivirus software before use.

NITDA further recommended enabling two-factor authentication on important accounts and avoiding the storage of banking passwords directly on web browsers.

For organisations, the agency urged companies to immediately sensitise staff about the DeepLoad threat, enable PowerShell Script Block Logging across Windows systems and review browser extensions for unauthorised installations.

The advisory also recommended blocking malicious domains, including holiday-updateservice[.]com, forest-entity[.]cc and hell1-kitty[.]cc, at firewall and DNS levels.

Additionally, organisations were advised to check for hidden WMI Event Subscriptions that could allow the malware to survive standard cleanup procedures.

NITDA said institutions that suspect infections should immediately disconnect affected systems from the internet, change all passwords from clean devices, isolate compromised systems, activate incident response teams and report incidents to the agency within 72 hours as required by law.

The latest warning has added to growing concerns over cyber attacks targeting Nigeria’s financial and digital infrastructure in recent months.

In April, the Nigeria Data Protection Commission (NDPC) warned about coordinated cyber threats targeting Nigeria’s financial systems and critical digital infrastructure, urging organisations to strengthen their data protection architecture.

The warning also followed the commission’s announcement of an investigation into an alleged data breach involving Remita Payment Services, Sterling Bank and other entities.

Similarly, the Corporate Affairs Commission (CAC) temporarily shut down its website between April 17 and April 20, 2026, following reports that about 25 million documents may have been exfiltrated during a suspected cyber attack.
