Ransomware Attacks Reaches Highest Level as 66% of Organisations Surveyed fell Victim to adversaries – Sophos Report
Sophos, a global leader in innovating and delivering cybersecurity as a service, has released its annual “State of Ransomware 2023[LS1] ” report, which found that in 76% of ransomware attacks against surveyed organizations, adversaries succeeded in encrypting data. This is the highest rate of data encryption from ransomware since Sophos started issuing the report in 2020.
The survey also shows that when organizations paid a ransom to get their data decrypted, they ended up additionally doubling their recovery costs ($750,000 in recovery costs versus $375,000 for organizations that used backups to get data back).
Moreover, paying the ransom usually meant longer recovery times, with 45% of those organizations that used backups recovering within a week, compared to 39% of those that paid the ransom.
Overall, 66% of the organizations surveyed were attacked by ransomware—the same percentage as the previous year.
This suggests that the rate of ransomware attacks has remained steady, despite any perceived reduction in attacks.
“Rates of encryption have returned to very high levels after a temporary dip during the pandemic, which is certainly concerning.
“Ransomware crews have been refining their methodologies of attack and accelerating their attacks to reduce the time for defenders to disrupt their schemes,” said Chester Wisniewski, field CTO, Sophos.
“Incident costs rise significantly when ransoms are paid. Most victims will not be able to recover all their files by simply buying the encryption keys; they must rebuild and recover from backups as well.
“Paying ransoms not only enriches criminals, but it also slows incident response and adds cost to an already devastatingly expensive situation,” said Wisniewski.
When analyzing the root cause of ransomware attacks, the most common was an exploited vulnerability (involved in 36% of cases), followed by compromised credentials (involved in 29% of cases). This is in line with recent, in-the-field incident response findings from Sophos’ 2023 Active Adversary Report for Business Leaders.
Additional key findings from the report include:
· In 30% of cases where data was encrypted, data was also stolen, suggesting this “double dip” method (data encryption and data exfiltration) is becoming commonplace
· The education sector reported the highest level of ransomware attacks, with 79% of higher education organizations surveyed and 80% of lower education organizations surveyed reporting that they were victims of ransomware
· Overall, 46% of organizations surveyed that had their data encrypted paid the ransom. However, larger organizations were far more likely to pay. In fact, more than half of businesses with revenue of $500 million or more paid the ransom, with the highest rate reported by those with revenue over $5 billion. This could partially be due to the fact that larger companies are more likely to have a standalone cyber insurance policy that covers ransom payments
“With two thirds of organizations reporting that they have been victimized by ransomware criminals for the second year in a row, we’ve likely reached a plateau. The key to lowering this number is to work to aggressively lower both time to detect and time to respond.
“Human-led threat hunting is very effective at stopping these criminals in their tracks, but alerts must be investigated, and criminals evicted from systems in hours and days, not weeks and months. Experienced analysts can recognize the patterns of an active intrusion in minutes and spring into action.
“This is likely the difference between the third who stay safe and the two thirds who do not. Organizations must be on alert 24×7 to mount an effective defense these days,” said Wisniewski.
Sophos recommends the following best practices to help defend against ransomware and other cyberattacks:
· Strengthen defensive shields with:
o Security tools that defend against the most common attack vectors, including endpoint protection with strong anti-exploit capabilities to prevent exploitation of vulnerabilities, and Zero Trust Network Access (ZTNA) to thwart the abuse of compromised credentials
o Adaptive technologies that respond automatically to attacks, disrupting adversaries and buying defenders time to respond
o 24/7 threat detection, investigation and response, whether delivered in-house or by a specialist Managed Detection and Response (MDR) provider
· Optimize attack preparation, including making regular backups, practicing recovering data from backups and maintaining an up-to-date incident response plan
· Maintain good security hygiene, including timely patching and regularly reviewing security tool configurations
Data for the State of Ransomware 2023 report comes from a vendor-agnostic survey of 3,000 cybersecurity/IT leaders conducted between January and March 2023. Respondents were based in 14 countries across the Americas, EMEA and Asia Pacific. Organizations surveyed had between 100 and 5,000 employees, and revenue ranged from less than $10 million to more than $5 billion.
The International Rescue Committee (IRC) has announced the formation of Airbel Ventures, a new humanitarian impact investing fund aimed at accelerating the introduction and scaling of breakthrough technologies in crisis-affected communities.
The fund will invest in companies whose ideas have the potential to change humanitarian response, including digital infrastructure for frontline health systems and climate-resilient agriculture.
The launch of Airbel Ventures follows a period of rapid innovation at the IRC, despite the humanitarian sector facing record funding cuts.
In the past year, the IRC’s Airbel Impact Lab has advanced more than twenty Artificial Intelligence (AI) and technology initiatives—from anticipatory action tools powered by climate and vulnerability data, to frontline service delivery using safe, orchestrated AI systems, to breakthrough diagnostic tools for emerging diseases.
Airbel Ventures’ first impact investment is in Signalytic, a company delivering solar-powered computing devices that ensure reliable electricity and connectivity for remote health facilities.
Following the investment, the IRC will pilot Signalytic’s technology with its Nigeria Health team, demonstrating the viability of next-generation digital infrastructure in humanitarian settings.
“We know breakthrough solutions already exist—what’s missing is the path to scale in humanitarian contexts,” said Dr. Jeannie Annan, Senior Vice President for Research & Innovation at the IRC and head of the Airbel Impact Lab.
MTN Nigeria, the country’s largest telecommunications operator, recorded a historic surge in network disruptions in 2025, suffering 9,218 fibre cuts as of December 31, alongside 211 base station sites affected by theft and vandalism, incidents that disrupted mobile and data services relied upon daily by millions of Nigerians.
The data was revealed by Dr Karl Toriola, chief executive officer/managing director, MTN Nigeria via a social media post titled ‘MTN Nigeria 2025 Wrapped’.
The scale of the damage highlights the growing vulnerability of Nigeria’s telecommunications infrastructure, which has come under increasing pressure from road construction activities, cable theft and deliberate acts of vandalism.
MTN said 5,478 fibre cuts occurred within just the first seven months of 2025, with 760 incidents recorded in July alone, underscoring the intensity of the challenge.
Some of the incidents had wide-ranging consequences, knocking out connectivity across multiple states simultaneously and affecting voice calls, data services, digital payments and enterprise operations.
The company described the situation as a national infrastructure problem, rather than an isolated corporate issue, given the economy’s deep dependence on mobile networks.
“These gaps were shaped by real operational challenges such as fibre cuts, theft, and vandalism. Their impact is felt directly by customers and reflected in what they tell us,” Toriola,
The disruptions were reflected in customer feedback volumes, as MTN handled an unprecedented number of complaints during the year. The operator said it resolved 1,624,263 customer complaints in 2025, spanning call centres, social media platforms, emails and physical service centres nationwide.
Despite the setbacks, MTN pointed to signs of operational resilience. The company retained its ranking as Nigeria’s best network by Ookla, returned to profitability after a challenging period, declared an interim dividend, and expanded its subscriber base to over 85 million users by September 2025.
The figures show that while Nigeria’s telecom operators continue to invest heavily in network expansion and customer service, infrastructure sabotage remains a major drag on service quality and operating costs.
MTN acknowledged that performance improvements remain a work in progress. “We are not where we want to be yet. We see you. We hear you. We exist because of you. And we will get better,” Toriola said.
As the company enters its 25th year of operations in Nigeria, Toriola said MTN is doubling down on customer-centricity, treating every piece of feedback as a guide for improvement, while also stepping up engagement with government agencies.
The CEO renewed calls for stronger regulatory and legal protections for telecommunications infrastructure, urging policymakers to classify fibre cables, base stations and other critical assets as national infrastructure and criminalise vandalism to deter repeat attacks.
Nigerian Communications Commission (NCC) has granted operating licences to six new Internet Service Providers (ISPs), effective January 1, 2026, raising the total number of authorised ISPs in the country to 231 from 225 recorded in December 2025.
NCC
The newly licensed firms are Intellvision Technologies Limited, Granet Technologies Limited, Fiber Sonic Limited, Dasol Solution Services Ltd, Boost ISP Limited, and Amazon Kuiper Nigeria Limited.
Five of these companies are headquartered in Lagos, while Granet Technologies Limited operates from Owerri in Imo State, highlighting the persistent concentration of broadband infrastructure in major commercial hubs like Lagos, Abuja, and Port Harcourt.
This development intensifies competition in Nigeria’s broadband market, which faces pressure from dominant mobile network operators such as MTN and Airtel, alongside rapid expansion by satellite providers like Starlink.
Traditional ISPs continue to grapple with shrinking customer bases, aggressive data pricing from telcos, and satellite disruptions, even as NCC data from Q2 2025 showed Spectranet, Starlink, and FibreOne controlling about 65 per cent of the 313,713 active ISP subscribers.
The inclusion of Amazon Kuiper Nigeria Limited marks a significant entry of global satellite broadband competition, building on Nigeria’s recent approvals for other low Earth orbit providers to enhance connectivity in underserved areas.
Industry analysts view the licences as a strategic push to improve internet quality amid rising demand for digital services, though geographic clustering underscores ongoing infrastructure challenges outside urban centres.
NCC’s move aligns with broader efforts to foster a competitive telecoms sector critical to Nigeria’s digital economy ambitions.
