Sophos Identifies Top Ransomware Families in Africa

Cyber security vendor Sophos has identified the top ransomware families that affected Africa in 2017.
According to Sophos, the Ceber ransomware accounted for 80% of attacks in Africa, followed by WannaCry (17%), and others like Jaff (1%), Locky (1%) and Petya (0.5%).
One of the most active kinds of ransomware out there, Cerber encrypts the files of infected users and demands money in exchange for enabling access to their files. It works even if a user is not connected to the Internet, so they can’t stop it by unplugging their PC.
Cerber, sold as a ransomware kit on the Dark Web, remains a dangerous threat, says Sophos, adding the creators of Cerber continuously update the code and charge a percentage of the ransom that the “middle-men” attackers receive from victims.
Regular new features make Cerber not only an effective attack tool, but perennially available to cyber criminals, the cyber security firm notes.
“This Dark Web business model is unfortunately working and, similar to a legitimate company, is likely funding the ongoing development of Cerber. We can assume the profits are motivating the authors to maintain the code,” says Dorka Palotay, SophosLabs security researcher and contributor to the ransomware analysis in the SophosLabs 2018 Malware Forecast.
The WannaCry ransomware attack was a May 2017 worldwide cyber attack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin crypto-currency.
“Looking at the whole world, WannaCry was responsible for 45.3% of the ransomware attacks, while in Africa this value is only 17%,” Palotay says.
“In Africa, clearly Cerber was the biggest ransomware threat this year, since 80% of the ransomware lookups was caused by Cerber, while this number is only 44.2% if we look at the whole world. Regarding the smaller families, the results are very similar.”
The SophosLabs 2018 Malware Forecast report recaps ransomware and other cyber security trends based on data collected from Sophos customer computers worldwide from 1 April to 3 October 2017.
One key finding shows that while ransomware predominately attacked Windows systems in the last six months, Android, Linux and MacOS platforms were not immune.
“Ransomware has become platform-agnostic. Ransomware mostly targets Windows computers, but this year, SophosLabs saw an increased amount of crypto-attacks on different devices and operating systems used by our customers worldwide,” says Palotay.
She notes that for the first time Sophos saw ransomware with worm-like characteristics, which contributed to the rapid expansion of WannaCry.
“This ransomware took advantage of a known Windows vulnerability to infect and spread to computers, making it hard to control.
“Even though our customers are protected against it and WannaCry has tapered off, we still see the threat because of its inherent nature to keep scanning and attacking computers. We’re expecting cyber criminals to build upon this ability to replicate as seen in WannaCry and NotPetya, and this is already evident with Bad Rabbit ransomware, which shows many similarities to NotPetya.”

Galaxy Backbone @ 20, Pledges Nationwide Connectivity, Data Sovereignty

Galaxy Backbone (GBB) Limited has mapped out strategies to strengthen Nigeria’s digital infrastructure in order to make the country globally competitive in the face of Artificial intelligence, blockchain, cloud computing and other emerging technologies aimed at securing the digital future of the country.

Prof Ibrahim Adeyanju, managing director and CEO of GBB, made this known during a press conference to unveil a flurry of activities to celebrate the 20th anniversary of GBB in Abuja on Monday, stressing that Galaxy Backbone has evolved from a connectivity provider into one of Nigeria’s most strategic digital infrastructure institutions.
Galaxy Backbone is a public enterprise of the Federal Government of Nigeria incorporated in 2006 with the primary mandate of setting up and operating a unified Information and Communication Technology (ICT) infrastructure platform that addresses the connectivity, transversal and other technology imperatives for Ministries, Departments and Agencies (MDAs) of the federal government and private entities.
He said in the last 20 years, the agency has invested in world-class data centre infrastructure, including uptime certified Tier III and Tier IV facilities that provide secure, resilient and reliable environments for hosting missions critical to systems and applications.
He noted that these facilities strengthen data sovereignty, ensure business continuity and help keep Nigeria’s most critical digital assets secure.
“Through our cloud infrastructure and the 1Government Cloud platform, government institutions can access scalable digital services without the burden of building costly infrastructure independently. This shared-services model improves efficiency, reduces costs and accelerates innovation.
“We have delivered platforms such as GovMail (the homegrown Official government email), collaboration tools, hosting services, connectivity solutions and shared applications that support thousands of public servants and hundreds of institutions every day,” he said.
He emphasized that the true value of Galaxy Backbone is not measured by kilometres of fibre, data centres or technology alone but by impact.
He explained that the GBB fibre infrastructure today spans almost 30 states of the federation, connecting government institutions and creating the foundation for digital government even as he pledged that the remaining states and local areas will all be captured in due course.
On cyber security, the GBB boss noted that the agency has strengthened cybersecurity capabilities and continues to invest in protecting government systems and critical national digital assets, against cyber-attacks.
“We have the digital infrastructure and we are collaborating with partners to use these emerging technologies. We also have a top tier cyber security operation center and they are multilayered such that even when there is a spike in cyber-attacks none of them have been successful so far.
He added that the GBB is collaborating with other government agencies like the National Security Adviser, The Nigeria Police, and Nigerian Communications Commission (NCC) National Information Technology Development Agency (NITDA) National Identity Management Commission (NIMC) to ensure that government information is protected.
Ibrahim Sani Mohammed, executive director Finance and Corporate Services of the GBB, while fielding questions noted that the agency has created enormous value and has contributed immensely in the digital ecosystem of Nigeria helping to support small and medium enterprises (SMEs).
Olusegun Olulade, executive director Customer Centrality and Marketing of the GBB, said that customers have remained the formidable partners in the GBB journey of 20 years, adding that the agency has developed the mechanism to ensure customer satisfaction as it intensifies efforts to build trust.

AI-Powered Cyber Threats Put Nigerian Banks on Alert

Nigerian banks are increasingly embracing artificial intelligence (AI) to improve customer service, strengthen fraud detection, and streamline operations.

However, the same technology driving innovation could also expose the country’s financial system to unprecedented cyber risks, according to a recent warning from the International Monetary Fund (IMF).
The IMF has cautioned that advanced AI tools are rapidly enhancing the capabilities of cybercriminals, making it easier and faster to identify and exploit vulnerabilities in banking systems, payment infrastructure, and digital platforms.
For Nigeria, where digital banking transactions have surged in recent years and financial institutions are becoming more interconnected, the implications could be significant.
The warning comes at a time when Nigerian banks are investing heavily in digital transformation.
From AI-powered customer support systems to automated fraud monitoring tools and digital lending platforms, financial institutions are relying more than ever on technology to drive growth and improve efficiency.
Yet experts warn that this digital expansion is also widening the attack surface for cybercriminals.
The IMF noted that advanced AI models can dramatically reduce the time and expertise required to discover software vulnerabilities.
This means attackers can launch more sophisticated and coordinated cyberattacks against multiple institutions simultaneously.
For Nigeria’s banking sector, which depends on common payment rails, cloud infrastructure, telecommunications networks, and shared service providers, a major cyber incident could quickly spread across the financial ecosystem.
Nigeria’s financial sector has undergone a remarkable digital revolution over the past decade.
Data from the Central Bank of Nigeria (CBN) show that electronic payments now account for trillions of naira in monthly transactions, driven by mobile banking, instant payments, fintech innovation, and the growing adoption of digital channels.
The success of platforms such as the Nigeria Inter-Bank Settlement System (NIBSS) Instant Payments network has made banking more accessible and efficient.
However, it has also increased dependence on interconnected digital infrastructure.
According to the IMF, this interconnectedness creates systemic vulnerabilities.
A cyberattack targeting a critical service provider, cloud platform, telecommunications network, or payment gateway could disrupt services across multiple banks at the same time.
Unlike traditional bank robberies or isolated cyber incidents, AI-enabled attacks have the potential to trigger widespread operational disruptions, affecting payment processing, customer access to funds, and confidence in the banking system.
The IMF warns that extreme cyber incidents could evolve from operational challenges into broader financial stability concerns.
If multiple banks are simultaneously affected by a cyberattack, customers may experience service outages, delayed transactions, or restricted access to deposits.
Such disruptions could undermine public confidence and create liquidity pressures, especially if panic withdrawals or transaction bottlenecks occur.
The concern is not merely theoretical.
Over the past few years, Nigerian financial institutions have experienced increasing levels of cyber fraud, phishing attacks, identity theft, and ransomware threats.
Although regulators and banks have improved cybersecurity frameworks, AI-driven attacks could significantly raise the sophistication and scale of these threats.
The IMF believes that the growing concentration of technology services could further amplify the risks.
Many Nigerian banks rely on a relatively small number of software vendors, cloud providers, telecommunications operators, and payment infrastructure providers. A successful attack on one critical provider could have cascading effects across the entire banking system.
This concentration risk is becoming more pronounced as financial institutions increasingly adopt AI solutions from a limited number of global technology companies.
Despite the risks, AI is also emerging as one of the most powerful tools available to banks in defending against cyber threats.

CSOs Raise Alarm over Nigeria’s Data Protection Crisis

A coalition of civil society organisations has warned that Nigerians’ personal information remains vulnerable to abuse despite existing data protection laws.

In a statement titled “Protected From the State, Not By It: Nigeria’s Data Protection Crisis Is a Crisis of Implementation,” the group said Nigeria developed one of Africa’s largest digital identity databases but failed to adequately protect the information it collects.
The coalition, comprising Media Rights Agenda (MRA), Paradigm Initiative (PIN), Digital Rights Lawyers Initiative (DRLI), Accountability Lab Nigeria, PROMAD Foundation, DigiCivic Initiative and others, noted that the National Identity Management Commission (NIMC) had enrolled more than 121 million Nigerians as of June 2025, while the country also operates under the Nigeria Data Protection Act (NDPA) 2023 and a dedicated Nigeria Data Protection Commission (NDPC).
However, the organisations argued that these safeguards failed to translate into meaningful protection for citizens.
According to the group, recent incidents involving alleged unauthorised access to sensitive government databases have exposed weaknesses in oversight and accountability mechanisms.
They cited reports surrounding the disclosure of voter registration information from the Independent National Electoral Commission (INEC) database and investigations that uncovered the online sale of sensitive identity records, including National Identification Numbers (NINs), for as little as ₦100.
“When the regulator’s own data is not safe, no citizen’s data is. A government that cannot protect its citizens’ data should, at minimum, be cautious about how aggressively it collects and deploys it. Nigeria has done the opposite. Under the NDPA, data controllers are required to undergo compliance audits filed with the NDPC, an obligation enforced against private entities even as public institutions, the largest holders of citizens’ data, face no comparable scrutiny,” the coalition stated.
The organisations also expressed concern about the expansion of state surveillance programmes, arguing that Nigeria lacked a comprehensive legal framework governing public surveillance systems.
They said existing laws did not clearly define the limits of surveillance, provide independent oversight, or require human rights impact assessments before such systems are deployed.
The coalition further criticised the continued use of provisions of the Cybercrimes Act against journalists, bloggers and social media users, despite a 2022 judgment by the ECOWAS Court of Justice declaring aspects of Section 24 of the law arbitrary and repressive.
According to the group, Nigeria’s data governance system currently places citizens in a vulnerable position where personal information is aggressively collected but inadequately protected.
“This is the asymmetry at the heart of the crisis: citizens are under-protected from data abuse and over-exposed to state monitoring and punishment,” the CSOs said.
They called on the Federal Government to strengthen enforcement of the Nigeria Data Protection Act, ensure public institutions are subjected to the same compliance requirements as private organisations, and publish the findings of investigations into alleged breaches involving government databases.
The coalition also urged authorities to establish an independent oversight framework for surveillance systems, amend Section 24 of the Cybercrimes Act, in line with the ECOWAS Court ruling, and strengthen accountability mechanisms across public institutions handling citizens’ data.
It warned that public trust in digital governance would continue to erode unless citizens are assured that their personal data is protected from misuse, unauthorised access and unlawful surveillance.
