75% of Healthcare Organizations Fall for Ransomware Attacks – Sophos Report
Sophos, a global leader in innovating and delivering cybersecurity as a service, on Thursday shared its sector survey report, “The State of Ransomware in Healthcare 2023,” which revealed that, among those organizations surveyed, cybercriminals successfully encrypted data in nearly 75% of ransomware attacks.
This is the highest rate of encryption in the past three years and a significant increase from the 61% of healthcare organizations that reported having their data encrypted last year.
In addition, only 24% of healthcare organizations were able to disrupt a ransomware attack before the attackers encrypted their data—down from 34% in 2022; this is the lowest rate of disruption reported by the sector over the past three years.
“To me, the percentage of organizations that successfully stop an attack before encryption is a strong indicator of security maturity. For the healthcare sector, however, this number is quite low—only 24%. What’s more, this number is declining, which suggests the sector is actively losing ground against cyberattackers and is increasingly unable to detect and stop an attack in progress.
“Part of the problem is that ransomware attacks continue to grow in sophistication, and the attackers are speeding up their attack timelines. In the latest Active Adversary Report for Tech Leaders, we found that the median time from the start of a ransomware attack to detection was only five days. We also found that 90% of ransomware attacks took place after regular business hours.
“The ransomware threat has simply become too complex for most companies to go at it alone. All organizations, especially those in healthcare, need to modernize their defensive approach to cybercrime, moving from being solely preventative to actively monitoring and investigating alerts 24/7 and securing outside help in the form of services like managed detection and response (MDR),” said Chester Wisniewski, director, field CTO, Sophos.
Additional key findings from the report include:
· In 37% of ransomware attacks where data was successfully encrypted, data was also stolen, suggesting a rise in the “double dip” method
· Healthcare organizations are now taking longer to recover, with 47% recovering in a week, compared to 54% last year
· The overall number of ransomware attacks against healthcare organizations surveyed declined from 66% in 2022 to 60% this year
· Compromised credentials were the number one root cause of ransomware attacks against healthcare organizations, followed by exploits
· The number of healthcare organizations surveyed that paid ransom payments declined from 61% last year to 42% this year. This is lower than the cross-sector average of 46%
“In 2016, the Red Cross Hospital of Córdoba in Spain suffered a ransomware attack that reached servers and encrypted hundreds of files, medical records and other important patient information. It was a major disruption to our operations and interfered with our ability to care for our patients.
“The stakes are high in ransomware attacks against healthcare organizations—and attackers know that—meaning we’ll always be a target. After this ransomware attack, we worked hard with Tekpyme to bolster our defenses, and now we have reduced our incident response time by 80%.
“I think the industry as a whole is making improvements, but there is still work to do, because of the constantly changing nature of cybercrime.
“Hopefully healthcare organizations can leverage the help that is available from security vendors such as Sophos to prevent a very real ‘threat to life’ if systems go offline due to a ransomware attack,” said José Antonio Alcaraz Pérez, head of information systems and communications at Cruz Red Andalusia in Spain.
“Cyberspace today is ripe with technically sophisticated actors looking for vulnerabilities to exploit. What all this translates to is a multidimensional cyberthreat of actors who have the tools to paralyze entire hospitals. Partnering with the private sector is critical to our mission. The information [they] share has real-world impacts and can save real businesses and real lives,” said Christopher Wray, FBI Director.
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-ransomware and anti-exploit capabilities
o 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 specialized Managed Detection and Response (MDR) provider
· Optimize attack preparation, including regularly backing up, practicing recovering data from backups and maintaining an up-to-date incident response plan
· Maintain security hygiene, including timely patching and regularly reviewing security tool configurations

Airtel Nigeria has reaffirmed its long-term commitment to strengthening Nigeria’s digital infrastructure and data access to bridge gaps in connectivity and unlock new opportunities in the country.
The company restated this commitment during a recent high-level inspection tour of the Nxtra Data Centre that is being developed through Nxtra by Airtel Africa at Eko Atlantic, Lagos, the highly rated smart city with ambition to become the Data Centre hub of Nigeria.
The inspection tour was led by the Chief Executive Officer of Airtel Nigeria, Dinesh Balsingh and the Chief Executive Officer of Nxtra by Airtel Africa, Yashnath Issur, with the esteemed chairman of Eko Atlantic Mr. Gabbi Massoud, the CEO of the lead Engineering firm Design Group Limited, Mr. Bayo Odunlami and tech journalists.
The Nxtra Data Centre went through a stringent design validation process and cleared the approval to proceed construction from Eko Atlantic.
Commenting on the developments, Mr Issur said the site visit was a milestone marker and an indication of the company’s commitment to delivering the world-class digital facility on time and ensure that, ultimately, the investments deliver reliable, secure, world-class services for Nigeria and the rest of the continent.
“This Nxtra Data Centre in Lagos represents a critical part of our long-term vision for Nigeria’s digital ecosystem. Today’s visit allows us to review progress, engage our stakeholders, and ensure that our infrastructure investments continue to meet global standards and local needs.
“This data centre will deliver critical high multi megawatt capacity in line with hyperscale customers and enable high density environment. We are putting the infra to bring the cloud to Nigeria,” he said.
The data centre, set to be the largest in Nigeria, is being established to deliver hyperscale and edge facilities across key African markets. With a load of 38 Megawatts, the Lagos facility is expected to serve as a major hub for data hosting, cloud services, content distribution, artificial intelligence, and enterprise solutions in West Africa.
In his remarks, Mr Balsingh reiterated that the data centre was progressing steadily towards the previously announced 2028 go live date.
“Since the announcement of this project, our focus has been on building a world-class facility that supports Africa’s digital transformation agenda. We are encouraged by the progress recorded so far and remain committed to delivering a secure, energy-efficient, and future-ready data centre for Nigeria,” he said.
During the tour, stakeholders were ushered through key sections of the site, including piling zones, where required structural requirements have been tested. Technical teams provided briefings on infrastructure design, security architecture, redundancy systems, and sustainability measures being implemented to ensure reliability and operational excellence.
Strategically located close to major fibre routes and undersea cable landing stations, the Eko Atlantic data centre is designed to enhance Nigeria’s data sovereignty, reduce latency, and improve access to reliable digital services for private and enterprise customers, significantly boosting the country’s data hosting capacity and supporting emerging technologies such as artificial intelligence and cloud computing.
Mr. Massoud noted that the inspection tour underscored the city’s dedication to infrastructure of global relevance.
“Eko Atlantic as a city with high quality infrastructure will contribute positively to boost the economy of Nigeria and is a perfect place for the development of the digital infrastructure of Nigeria.

Google has partnered with top African research institutions to unveil WAXAL, a massive open-access speech dataset aimed at giving over 100 million people across Sub-Saharan Africa a stronger voice in the AI future.
The initiative, announced Monday, targets a key digital gap by supplying high-quality data for 21 local languages, such as Hausa, Yoruba, Luganda, and Acholi. It includes 1,250 hours of transcribed natural speech and more than 20 hours of studio-grade recordings for advanced synthetic voice tech.
Voice AI has exploded globally, yet Africa’s 2,000-plus languages suffer from severe data shortages, sidelining hundreds of millions from native-tongue tech access. WAXAL, three years in the making with Google funding, changes that equation.
“This dataset lays the groundwork for students, researchers, and entrepreneurs to craft tech in their own languages, impacting over 100 million lives,” said Aisha Walcott-Bryantt, Head of Google Research Africa.
She highlighted its potential for African innovators to develop educational tools and voice services that spark economic growth continent-wide.
Community-led from the start, the project involved Makerere University (Uganda), University of Ghana, Digital Umuganda (Rwanda), and others. These partners own the data outright, pioneering fair AI collaboration models.
Covered languages: Acholi, Akan, Dagaare, Dagbani, Dholuo, Ewe, Fante, Fulani (Fula), Hausa, Igbo, Ikposo (Kposo), Kikuyu, Lingala, Luganda, Malagasy, Masaaba, Nyankole, Rukiga, Shona, Soga (Lusoga), Swahili, Yoruba.
