Cybercriminals Successfully Encrypted Data in Ransomware Attacks on Nearly 75% of Healthcare Organizations, Sophos Survey
Only 24% of Healthcare Organizations Were Able to Disrupt a Ransomware Attack Before Attackers Encrypted Their Data. This is the Lowest Rate of Disruption in 3 Years, reports SANDRA ANI


Sophos, a global leader in innovating and delivering cybersecurity as a service, today 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:
- Security tools that defend against the most common attack vectors, including endpoint protection with strong anti-ransomware and anti-exploit capabilities
- 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 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

Optometry in a Changing World: Adapting to Emerging Trends


In July, I had the privilege of attending the 48th National Conference and Vision Expo of the Nigerian Optometric Association (NOA) in Umuahia, Abia State.
It was a landmark gathering that brought together professionals, policymakers, researchers, and business leaders in the vision space at the national and global levels.
With the theme “Optometry in a Changing World – Adapting to Emerging Trends,” the conference was timely and necessary.
We are living in an era of unprecedented change in healthcare delivery, technology, patient behaviour, and business models. Optometry is no exception to these trends. Our profession is at a crossroads: traditional practice models are being challenged by automation, digital health technology, and rising patient expectations. This conference challenged us to rethink, realign, and reposition ourselves for the future.
The decision to host the conference in Abia State proved to be both symbolic and significant. For many attendees, it was the first opportunity to witness firsthand the bold infrastructural developments and renewal projects taking place under the administration of Governor Alex Otti.
From rehabilitated roads to clean urban corridors, the visible transformation in the state echoed the spirit of the conference theme, one of change, adaptation, and progress. For me, too, it was homecoming of sorts, a return to my ancestral home.
The capital city, Umuahia, was not just a host, but an education in the essence of what is possible when vision meets execution, an ideal allegory for the way optometry in Nigeria must proceed. The overarching theme was not just a slogan; it was a call to action.
From the plenary sessions to technical workshops, several key ideas emerged about how optometrists can adapt.
The first is the need to embrace technology and innovation. Incorporating artificial intelligence (AI), tele-optometry, and electronic health records is no longer optional. These tools help improve diagnostics, enhance patient experience, and optimise practice management. Optometrists must be open to adopting digital platforms for consultations, patient tracking, and education.
Secondly, continuous learning and re-skilling are indispensable for the modern-day optometrist. Emerging diseases, changing refractive error patterns, and evolving treatment protocols demand ongoing education. Whether it’s attending conferences, taking online courses, or subscribing to global journals, the 21st-century optometrist must become a lifelong learner.
Besides, eye health care must become patient-centred. Today’s patients are informed, empowered, and expect more. The optometrist must provide personalised care, effective communication, and holistic service delivery. For the most part, this involves blending clinical excellence with professionalism and empathy.
Additionally, public health integration is on the agenda. Nigeria’s eye health burden is growing, particularly among marginalised populations. Optometrists must assume more prominent roles in public health and advocacy for eye care in primary healthcare.
Moreover, practice diversification is essential. Beyond clinical work, optometrists are encouraged to explore specialities such as low vision therapy, sports vision, neuro-optometry, and occupational vision care. Diversifying services not only enhances revenue but also amplifies the impact of the profession.
Furthermore, practitioners must seek business and leadership development. Running a successful optometric practice now demands strong entrepreneurial skills, financial literacy, branding, and marketing. These competencies were highlighted during breakout sessions and business masterclasses at the conference.
The conference delivered on its promise of professional upliftment. We attended scientific paper presentations, listened to keynote addresses by thought leaders, and participated in panel discussions that explored a range of topics, from policy reforms to clinical innovation.
One of the most engaging sessions focused on the future of optometry education in Nigeria. It called for upgrading training curricula, enhancing exposure to emerging technologies, and improving internship opportunities. This is crucial if the next generation of optometrists is to meet global standards.
On the sidelines of the conference, the Vision Expo was a beehive of activity. It provided a rare opportunity for practitioners to interact directly with equipment manufacturers, pharmaceutical companies, and service providers. For many, it was an ideal time to purchase new diagnostic tools, update clinical software, and explore new product lines that can enhance their practice.
Aside from the formal sessions, the conference was a heartwarming reunion for colleagues, classmates, and mentors. These social interactions, often overlooked, play a vital role in the growth of the profession. They offer comfort, inspiration, and even opportunities for mentorship and collaboration.
One thing is clear: the future of optometry in Nigeria will not be shaped by those who resist change, but by those who embrace it – with open minds, skilled hands, and passionate hearts.
In many ways, this year’s conference in Abia State felt like a turning point. From the inspiring infrastructure developments we witnessed across the state to the powerful ideas exchanged in lecture halls and exhibition booths, it was a reaffirmation that change is possible – and indeed, necessary.
Kudos to the leadership of the Nigerian Optometric Association for organising a world-class event. The bar has been raised, and so has our vision for what is possible.
As professionals committed to a better vision, let us now see more clearly and act more boldly.

First Lady Oluremi Tinubu Flags off Free to Shine Campaign Against HIV/AIDS, other STDs in Enugu
Gov. Mbah, wife, pledge collaboration, reports SANDRA ANI


Nigeria’s First Lady, Senator Oluremi Tinubu, has flagged off the Free to Shine Triple Elimination Campaign, an initiative of the Organisation of African First Ladies for Development, OAFLAD, and global partners to eradicate HIV/AID, Syphilis and Hepatitis by 2030.
Flagging-off the campaign at the International Conference Centre, Enugu, on Tuesday, the founder of the Renewed Hope Foundation, Senator Tinubu said the initiative was an imperative, since Nigeria bore the highest burdens of HIV infection in sub Saharan African due to her large population.
“We launched the campaign in January 2025 and have flagged it off in five political zones of North Central, North East, North West, South South and South West. Today, we have flagged off the campaign in southeast to complete the Free to Shine campaign.
“Our aim is to reduce HIV infection among women, prevent mother and child transmission and ensure that every child born with it gets the necessary treatment,” Tinubu said.


She thanked Governor Peter Mbah of Enugu State and his Wife, Mrs. Nkechinyere Mbah and the people Enugu State for the warm reception accorded to her and her entourage. During her two-day working visit.
Throwing his weight behind the campaign, Governor Mbah, said his administration had taken health seriously because a healthy population is the foundation on which progress is built.
“Here in Enugu State, we have aligned our healthcare priorities with the vision of the ‘Free to Shine Campaign.’
“By September, we would have completed and fully equipped 260 Type 2 Primary Healthcare Centres in all wards — each with accommodation for health workers to ensure round-the-clock care.
“We have also strengthened our secondary and tertiary healthcare systems and broadened access to health insurance and emergency services, especially for the most vulnerable.
“These efforts are already yielding results — with a significant reduction in maternal, under-five and infant mortality.
“But we know the work is not done. No health system can thrive in isolation or assume it no longer needs support. This is why we embrace the goals of the ‘Free to Shine Campaign’ — goals that seek to eliminate stigma, expand access to HIV treatment, and, most importantly, end mother-to-child transmission of HIV,” he stated.
The First Lady of Enugu State, Mrs Mbah, commended Senator Tinubu and OAFLAD for providing leadership against the scourges of HIV/AIDS and other sexually transmitted diseases.
“I commend the First Lady, Her Excellency Senator Oluremi Tinubu, for demonstrating leadership and commitment to the health and well-being of Nigerians.
“As 2023 data from the Joint United Nations Programme on HIV/AIDS (UNAIDS) shows, Nigeria has one hundred and forty thousand (140,000) children aged 0 – 14 living with HIV, with twenty-two thousand (22,000) deaths each year. This is an enormous public health burden with vast social and economic implications. So, the ‘Free to Shine Campaign’ is indeed a creation of necessity,” Mrs. Mbah said.
She expressed total support for the initiative, noting that “collaboration is the driving force of change and development.”
“When we collaborate, problems that seem intractable are solved. So, I am confident that the goals of this campaign will be achieved in Enugu State, in Nigeria – and across Africa. What is required is whole-hearted dedication,” she concluded.
The event featured a general overview of the Free to Shine Campaign, by the Executive Secretary for OAFLAD, Dr. Nardos Berhanu, testimonials and experience sharing by persons living with HIV/AIDS, drama presentation by Members of the National Youth Service Corps, and goodwill messages by development partners, among others.
Meanwhile, the Nigerian First Lady was conferred with the chieftaincy title of Ugosinamba (Precious Jewel/Eagle from another kingdom) by the Enugu State Council of Traditional Rulers, citing her love for Enugu and service to the nation and humanity.

Enhancement of Military Health Services: Matawalle Meets U.S. Deputy Assistant Secretary of Defence for Health


In a significant move to bolster Defence Health Services and strengthen the partnership between the United States and Nigeria, the Minister of State for Defence, H.E. Dr. Muhammad Bello Matawalle, met with a U.S. delegation led by Dr. David Smith, Deputy Assistant Secretary of Defence for Health.
A statement endorsed by Henshaw Ogubike, director of Information and PR at the Ministry, shows that the the meeting focused on enhancing the existing collaboration in defence health between the two nations, which has previously facilitated the establishment of high-tech laboratories in Nigeria.
The Honourable Minister commended the U.S. for their efforts and urged for the expansion of these medical facilities beyond Abuja and Lagos to reach more derserved regions.
Dr. Matawalle emphasized the strategic integration of health services to improve the welfare of the Armed Forces of Nigeria, stating, “A healthy military is the backbone of a strong nation.” He reiterated the government’s commitment to ensuring that military personnel have access to top-tier healthcare services and facilities. To this end, he called for an increase in the defence budget allocated to health, viewing it as a vital investment in the nation’s future and stability.
Furthermore, the Minister highlighted that these initiatives align with Nigeria’s broader commitment to enhancing military readiness while addressing public health challenges that affect both service members and the civilian population. He noted that President Bola Ahmed Tinubu’s administration is dedicated to improving healthcare for military personnel and civilians, recognizing healthcare as a cornerstone of national security.
In his remarks, the Permanent Secretary of the Ministry of Defence, Dr. Ibrahim Abubakar Kana mni, stated that this initiative would positively impact military health and serve as a model for strengthening Nigeria’s overall healthcare system. “This collaboration marks a turning point for Nigeria’s defence health system,” he asserted.
Dr. Smith praised the Minister for his proactive approach to health readiness, underscoring the critical connection between health systems and military effectiveness. “Health is as crucial as any weapon system in ensuring military success, and we are committed to supporting Nigeria’s efforts to enhance its defence health system,” he remarked.
The U.S. delegation is in Nigeria to further advance initiatives aimed at sustaining progress against HIV, accelerating efforts towards the United Nations’ 95-95-95 goals, and working towards the elimination of HIV as a public health threat by 2030.
