Nigeria’s Cybercrime Surge: Sophisticated Attacks, Rising Losses, and Policy Gaps (2018–2025)
Cybercrime in Nigeria has grown more sophisticated and more costly between 2018 and 2025, according to new research by Dr. Julius Bolade Anjorin of Miva Open University. Published in 2026 in the International Journal of Advanced Technology and Social Sciences (IJATSS), the study tracks how digital transformation has reshaped criminal activity across Africa’s largest economy—and how policy responses are struggling to keep pace.
Anjorin’s analysis shows that reported cybercrime incidents rose from about 3,800 cases in 2018 to more than 16,500 in 2024. Financial losses in Nigeria’s banking sector alone exceeded ₦56 billion between 2021 and 2024. The findings matter because Nigeria is one of Africa’s fastest-growing digital economies, with more than 220 million active mobile subscriptions and a rapidly expanding fintech ecosystem. As connectivity increases, so does vulnerability.
Why Nigeria’s Cybercrime Trend Matters
Nigeria’s digital boom has fueled e-commerce, mobile banking, and cross-border payments. Mobile money transactions surged from ₦2.3 trillion in 2018 to over ₦18.7 trillion in 2024. Internet penetration climbed from 47 percent to more than 75 percent over the same period.
This rapid growth has created what cybersecurity experts call an “expanded attack surface.” Every new user, device, and digital payment channel represents a potential target. Anjorin’s research places Nigeria’s cybercrime challenge within broader global concerns about ransomware, online fraud, cryptocurrency exploitation, and digital identity theft.
Former INTERPOL cybercrime director Craig Jones, cited in the study, has warned that Africa’s mobile-first digital growth makes the region especially exposed to malware, SIM-swapping, and ransomware attacks. Nigeria is now ranked among the top five countries globally in cybercrime prevalence based on early 2025 data.
How the Study Was Conducted
Dr. Julius Bolade Anjorin used a qualitative documentary research design combined with quantitative trend analysis. Instead of interviewing offenders directly, he examined official reports and secondary data from:
-Nigeria Police Force National Cybercrime Centre (NPF-NCCC)
-Economic and Financial Crimes Commission (EFCC)
-Nigeria Deposit Insurance Corporation (NDIC)
-Central Bank of Nigeria (CBN)
-Nigerian Communications Commission (NCC)
-Legislative and policy documents, including amendments to cybercrime laws
The study triangulated multiple data sources to identify trends between 2018 and 2025. While official statistics likely underestimate actual incidents due to underreporting, consistent patterns emerged across agencies.
Key Findings: Cybercrime Is Changing Fast
Traditional “419” fraud is declining in dominance
Advance-fee fraud, historically associated with Nigeria’s “419” scams, declined by about 12 percent between 2018 and 2024. It remains present but no longer dominates the cybercrime landscape.
Business Email Compromise (BEC) is exploding
Business Email Compromise cases increased nearly twentyfold during the study period. Criminal groups infiltrate corporate email systems, manipulate payment instructions, and redirect large transactions. This tactic now represents one of the most financially damaging forms of cybercrime in Nigeria.
Ransomware is rising sharply
Ransomware incidents jumped more than 3,700 percent between 2018 and 2024. Several attacks targeted banks, healthcare facilities, and government agencies. In one major 2023 case, a ransomware attack disrupted banking services and caused substantial financial losses.
Sextortion and online harassment are growing
Sextortion cases increased by over 2,000 percent. Nearly 60 percent of victims are under 30 years old. Social media and dating platforms are frequently used to lure victims and obtain compromising images.
Financial sector losses are escalating
Bank fraud losses linked to cyber-enabled channels rose from ₦5.12 billion in 2018 to ₦31.89 billion in 2024. Mobile banking, POS systems, BEC schemes, and cryptocurrency channels are the primary vectors.
Who Are the Offenders?
The study shows that most convicted cybercriminals are:
-Male
-Aged 18–35
-Often with secondary or tertiary education
This challenges the narrative that cybercrime is driven solely by poverty. Many offenders possess technical skills and educational qualifications that could be used in legitimate employment. Anjorin describes this as a form of “criminal innovation,” emerging where digital skills meet limited formal economic opportunities.
Cybercrime in Nigeria is also increasingly transnational. Criminal networks collaborate across borders, making investigations more complex and requiring international cooperation.
Policy Responses: Stronger Laws, Persistent Gaps
Nigeria has updated its legal framework with the Cybercrimes (Prohibition, Prevention, Etc.) (Amendment) Act, 2024, building on the 2015 law. The amendments address cryptocurrency fraud, expand investigative powers, and introduce tougher penalties.
The country also established the Nigeria Data Protection Commission under the 2023 Data Protection Act to strengthen oversight of digital privacy and data security.
In addition, the Joint Case Team on Cybercrimes (JCTC) was launched in 2025 to improve coordination among law enforcement agencies.
However, Anjorin finds that implementation lags behind legislation. Digital forensic infrastructure remains underdeveloped, investigators lack sufficient tools and training, and inter-agency coordination is inconsistent. Mutual legal assistance with foreign governments remains slow and bureaucratic.
As Dr. Julius Bolade Anjorin of Miva Open University notes, “Legislative frameworks have strengthened considerably, but capacity constraints and coordination challenges continue to impede effective cybercrime control.”
Real-World Implications
The findings carry major implications:
For Government
For Universities
For Businesses
For Citizens
Nigeria’s experience also offers lessons for other developing economies undergoing rapid digital transformation. Growth without adequate cybersecurity infrastructure can produce parallel expansion in digital crime.
