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.
Telecommunications operators in Nigeria are considering shifting from the current national tariff structure to a regional tariff regime that accounts for state-specific operational challenges.
They say this is because the challenges and costs of running their businesses vary significantly from state to state.
Currently, phone companies in Nigeria have a single national tariff for their services, meaning everyone pays the same amount no matter where they live.
However, the telcos argue that this system doesn’t account for the fact that some states have higher operating costs due to issues like attacks on their equipment and multiple taxes.
This proposal was discussed at the 7th edition of the Policy Implementation Assisted Forum (PIAFo) in Lagos, where industry leaders highlighted the need for a pricing model that reflects the ease—or difficulty—of doing business in each state.
Gbenga Adebayo, chairman, Association of Licensed Telecommunications Operators of Nigeria (ALTON), specifically pointed out that the high cost of doing business in some states is a major concern and increases their expenses. He suggested that if negotiating with certain states to reduce these costs is impossible, then the added expense of operating there should be reflected in the service prices in those areas.
“We may have to reconsider the issue of our national tariffs and look at regional tariffs. If you are aware that the cost of doing business is high in a particular state and it’s impossible to negotiate with them, factor the cost of deployment in those areas into the cost of providing services,” he said.
Tony Emoekpere, president, Association of Telecommunications Companies of Nigeria (ATCON), agreed that the current national tariff is unfair because operational costs are not the same across the country.
He believes that states that make it easier for telecom companies to operate should be rewarded, while those that create difficulties should see higher service costs.
9mobile, telecommunications operator, has described as untrue the rumors suggesting that it has shut down its operations.
according to the telcos, these claims are entirely baseless and aimed at causing unnecessary panic among our valued subscribers, the mobile operator said in a statement.
“We understand that some customers have recently faced challenges, particularly with Mobile Number Portability (MNP), a service that enables seamless network switching.
“We want to clarify that 9mobile has never restricted customers from porting to other networks. We remain fully compliant with industry regulations and committed to delivering fair, transparent, and customer-focused services.
“While there have been temporary technical challenges affecting MNP, these issues have now been largely resolved. Some minor delays may still occur due to ongoing system optimizations, but we are actively working to ensure a smoother experience for all users.
“As a proudly Nigerian brand, we embody the resilient spirit of our people and remain steadfast in our commitment to overcoming challenges. We acknowledge the temporary service disruptions some customers may have experienced in different locations.
“However, we assure you that these disruptions are part of a broader transformation effort aimed at modernizing our infrastructure and improving overall service quality.
“Our ongoing investments in network upgrades and service expansion will soon yield significant improvements, ensuring reliable connectivity for individuals, businesses, and communities.
“We sincerely appreciate the patience and loyalty of our subscribers during this transition. While challenges exist, we are making significant progress and are confident that brighter days are ahead. We remain dedicated to providing exceptional service and keeping you connected to limitless opportunities”.
Nigeria Data Protection Commission (NDPC) has initiated an investigation into the data processing practices of Tiktok and Truecaller, following growing concerns about potential privacy violations.
Dr. Vincent Olatunji, the Chief Executive Officer of the NDPC, made the announcement today during a press conference in Abuja, where he also revealed the issuance of the Nigeria Data Protection Act – General Application and implementation directive (NDPC Act – GAID), 2025.
Dr Olatunji stated that the commission’s primary concern is how these platforms manage Nigerian users’ personal data, including potential breaches of consent, data sharing with third parties, and overall compliance with the Nigeria Data Protection Act (NDPA), 2023. He confirmed that the NDPC is actively investigating Tiktok and Truecaller’s data processing activities to ensure they comply with Nigeria’s data protection laws.
“The goal is to safeguard the privacy rights of Nigerians and hold organizations accountable for how they collect, store, and use personal data,” he added.
This investigation comes amid increasing scrutiny of global tech companies regarding data privacy, especially concerning how personal information is processed, stored, and transmitted beyond national borders.
The NDPC act – GAID, 2025, issued today, provides a detailed framework for implementing Nigeria’s data protection law, outlining compliance guidelines, enforcement mechanisms, and obligations for both public and private organizations.
Dr Olatunji emphasized that the directive aims to strengthen Nigeria’s digital economy by fostering trust in data governance while ensuring individuals’ rights to privacy are respected in accordance with international best practices.
He reiterated that companies operating in Nigeria must comply with the country’s data protection regulations or face regulatory actions, including fines and potential restrictions.
The NDPC has urged the public to report any data privacy violations and reaffirmed its commitment to transparency and due process in its investigations.
The commission noted that reporting data breaches has become more accessible through dedicated channels on its official website.
