Data Encryption from Ransomware Reaches Highest Level in Four Years, Sophos’ Annual State of Ransomware Report Finds
Report by SANDRA ANI
- Paying the Ransom Doubles Recovery Costs
- Rate of Ransomware Attacks Remains Steady, with 66% of Organizations Surveyed Reporting They Were a Victim of Ransomware
Sophos, a global leader in innovating and delivering cybersecurity as a service, today released its annual “State of Ransomware 2023 ” 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:
- 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
- Adaptive technologies that respond automatically to attacks, disrupting adversaries and buying defenders time to respond
- 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.

NITDA DG Inaugurates National Technical Working Group on Cloud Infrastructure
REPORTER: Sandra Ani
In a significant move to bolster Nigeria’s digital infrastructure, the National Information Technology Development Agency (NITDA) has inaugurated the Technical Working Group (TWG) on National Cloud Infrastructure.
This initiative aims to enhance local cloud capabilities, attract hyper-scale investments, and position Nigeria as a leading technology hub in Africa.
Speaking at the inauguration, NITDA’s Director-General, Kashifu Inuwa, CCIE, emphasised the need for accurate data and regulatory frameworks to support these initiatives, necessary for Nigeria to control its digital infrastructure, data, and technological future noting that,
“Without this foundation, we cannot achieve true digital sovereignty. Our goal is to build an ecosystem where both local data centre providers can scale, and global hyper-scalers see Nigeria as a viable investment destination.”
While identifying lack of accurate data on Nigeria’s IT infrastructure as significant challenge, Inuwa noted that while Africa comprises nearly 19% of the world’s population, it hosts less than 1% of global data centres.
“This disparity, coupled with limited insights into Nigeria’s existing IT capacity, hampers investment efforts and without clear data on our infrastructure, attracting investment becomes challenging,” he said.
The NITDA boss maintained that, to address this, NITDA commissioned comprehensive research to assess Nigeria’s digital landscape which findings have highlighted the need for improved regulatory frameworks, clearer investment incentives, and stronger public-private collaboration. He added that subsequently upon this, NITDA has engaged global consultants to redefine strategies for cloud development.
As the TWG embarks on its mission, NITDA urges industry experts, policymakers, and stakeholders to contribute their expertise and resources. “With collective effort, Nigeria can emerge as the premier digital hub for West and Central Africa,” Inuwa concluded.
While corroborating the Director General’s point of views, Acting Director of Regulation and Compliance, Barrister Emmanuel Edet, underscored the importance of regulatory intervention in fostering a robust digital economy.
“Our objective is to establish policies and legal frameworks that support cloud development, enabling us to securely host and manage our data. This is crucial for the growth of our digital economy, he said.”
He also highlights the necessity of capacity building, stating that, “Equipping ourselves with top-tier training and expertise is essential to fully leverage digital technologies.” Barrister Edet called on all stakeholders to actively participate in shaping Nigeria’s digital future.
“Collaboratively, we must develop a framework that reflects our national interests, and it should be widely accepted. This effort will define Nigeria’s role in the global digital arena, he observed.
The TWG will help in the drive to attract hyperscale investments and enhance local cloud capabilities by proffering measures to encourage the use of accurate data, recommend the enactment and compliance to enabling policies.
Members of the TWG which includes Google, AWS, IBM, Oracle, Microsoft, HUAWEI Cloud, Equinix, Kasi, Rack Centre, Africa Data Centres, several other data centre operators and the Nigeria Data Protection Commission expressed support and readiness to volunteer and contribute resources.
…Nearly 80% of Organizations Hit by Ransomware Took More than a Week to Recover
Sophos, a global leader of innovative security solutions for defeating cyberattacks, today released a sector survey report, “The State of Ransomware in Healthcare 2024,” which revealed that the rate of ransomware attacks against healthcare organizations has reached a four-year high since 2021.
Of those organizations surveyed, two-thirds (67%) were impacted by ransomware attacks in the past year, up from 60% in 2023.
The rising rate of ransomware attacks against healthcare institutions contrasts with the declining rate of ransomware attacks across sectors; the overall rate of ransomware attacks fell from 66% in 2023 to 59% in 2024.
Alongside an increase in the rate of ransomware attacks, the healthcare sector reported increasingly longer recovery times.
Only 22% of ransomware victims fully recovered in a week or less, a considerable drop from the 47% reported in 2023 and 54% in 2022.
In addition, 37% took more than a month to recover, up from 28% in 2023, reflecting the increased severity and complexity of attacks.
“While we’ve seen the rate of ransomware attacks reach a kind of “homeostasis” or even decline across industries, attacks against healthcare organizations continue to intensify, both in number and scope. The highly sensitive nature of healthcare information and need for accessibility will always place a bullseye on the healthcare industry from cybercriminals. Unfortunately, cybercriminals have learned that few healthcare organizations are prepared to respond to these attacks, demonstrated by increasingly longer recovery times. These attacks can have immense ripple effects, as we’ve seen this year with major ransomware attacks impacting the healthcare industry and impacting patient care,” said John Shier, field CTO, Sophos.
“To combat these determined adversaries, healthcare organizations must adopt a more proactive, human-led approach to threat detection and response, combining advanced technology with continuous monitoring to stay ahead of attackers.”
Additional findings from the report include:
· Ransom Recovery Costs Surge: The mean cost of recovery in a healthcare ransomware attack was $2.57 million in 2024, up from $2.2 million in 2023 and double the 2021 cost
· Ransom Demands vs Payments: 57% of healthcare institutions that paid the ransom ended up paying more than the original demand
· Root Cause of Attack: Compromised credentials and exploited vulnerabilities were tied for the number one root cause of attack, each accounting for 34% of attacks
· Backups Targeted: 95% of healthcare organizations hit by ransomware in the past year said that cybercriminals attempted to compromise their backups during the attack.
· Increased Pressure: Organizations whose backups were compromised were more than twice as likely to pay the ransom to recover encrypted data (63% vs. 27%)
· Who Pays the Ransom: Insurance providers are heavily involved in ransom payments, contributing in 77% of cases. 19% of total ransom payment funding comes from insurance providers
The latest Sophos report on real-world ransomware experiences explores the full victim journey, from attack rate and root cause to operational impact and business outcomes, of 402 healthcare organizations.
The results for this sector survey report are part of a broader, vendor-agnostic survey of 5,000 cybersecurity/IT leaders conducted between January and February 2024 across 14 countries and 15 industry sectors.
