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

Irvine Partners, the woman-led, African-born creative communications agency operating across Nigeria, has cemented its position as a disruptive force on the global stage following a landmark week of international industry recognition for its CEO and founder, Rachel Irvine.
Rachel-Irvine-CEO-Irvine-Partners
Irvine has been named to Campaign UK’s prestigious 40 over 40 list for 2026, while simultaneously earning a place on PRovoke Media’s Innovator 25 EMEA index – two of the communications industry’s most closely watched honours, secured in the same week. The achievement places her among the most influential and progressive communications leaders across Europe, the Middle East, and Africa.
For Nigeria – Africa’s largest economy and one of its most competitive and complex communications environments – the recognition speaks directly to something the local industry has long understood: that the strategic thinking, cultural intelligence and executional precision forged in African markets is not a regional advantage. It is a global one.
Irvine Partners brings this philosophy to some of the world’s most prominent digital and consumer brands in the Nigerian market, including TikTok, Spotify, Uber and Google – organisations that demand communications work of the highest international calibre, delivered with genuine local understanding.
An African agency rewriting the global narrative
Campaign UK’s 40 over 40 celebrates individual excellence, leadership and lasting impact within the British media and marketing landscape. PRovoke Media’s Innovator 25 spotlights those who are dismantling traditional PR structures, advancing data-led practice, and reshaping how the industry operates. To earn both in a single week is rare by any measure.
What underpins both honours is a story that begins not in London but in Africa – in the dynamic, high-stakes communications environments of markets like Nigeria, where agencies must be sharper, faster and more culturally precise than anywhere else in the world.
“These accolades are less about my own journey and far more about where Irvine Partners is going as a collective,” says Rachel Irvine. “For a long time, the global communications industry treated African agencies as local executors of global strategies. What we’ve proven over the past few years is that the technical craft, cultural capital, and data frameworks built within our agency are not just scalable for the continent; they are world-class.”
Built on the same ethos that works in Lagos
The recognition follows the agency’s strong performance at the IN2 SABRE Awards EMEA, where Irvine Partners took major wins for Unicorn School – its proprietary internal talent development programme – and for its advanced data analytics capability, alongside notable shortlists for global clients including Spotify and Uber.
Nigeria’s communications market is one of the most demanding in the world. Consumer audiences are sophisticated and discerning. The media environment is layered, fast-moving and deeply attuned to authenticity. Brands that succeed here do not do so through generic messaging – they do so through precision, cultural credibility and strategic consistency. These are precisely the competencies that Irvine Partners has built its international reputation on.
“The PR landscape has fundamentally shifted,” Irvine adds. “Clients no longer want siloed regional strategies; they want intelligent, culturally intuitive storytelling backed by bulletproof analytics that move the business needle. We built our foundations on that exact ethos in highly dynamic markets, and bringing that specific DNA to the UK and EMEA regions is why we are winning.”
The agency’s agile, borderless model – deliberately structured to move at the speed of modern brands rather than the pace of legacy networks- is one that Nigerian communications professionals will recognise as a natural evolution of how the best African agencies have always operated: lean, sharp and built for impact.
Underlying both honours is Irvine’s sustained commitment to talent development and cultural diversity across all of the agency’s wholly owned offices – a principle as central to its Lagos work as to any other market in its growing global footprint.
Mark Zuckerberg, Meta Chief Executive Officer, has announced a major leadership change at WhatsApp, confirming that Will Cathcart will step down as head of the messaging service after seven years in office.
Zuckerberg made the announcement in a post shared on Facebook on Monday, June 22, 2026, praising Cathcart’s contributions to the growth of the platform.
According to him, Cathcart played a key role in expanding WhatsApp’s global user base to over three billion people while promoting privacy-focused communication across its services.
“Will’s been one of Meta’s most important and effective leaders, helping to bring WhatsApp to over 3 billion people and championing privacy for our community,” Zuckerberg stated.
The Meta CEO also announced that Kunal Shal will take over leadership of WhatsApp.
He described Shal as a “builder” with strong international experience, adding that his leadership style aligns with Meta’s long-term vision for the messaging platform.
Meta said the transition is aimed at strengthening WhatsApp’s role in both personal and business communication globally, as the platform continues to expand its services across markets.
Industry observers say the leadership change marks a significant transition for WhatsApp, which has grown rapidly under Cathcart’s stewardship, particularly in areas of privacy, encryption, and enterprise messaging solutions.
However, Meta has not disclosed the exact timeline for the leadership handover or further structural changes within the messaging division.
The company reaffirmed its commitment to maintaining WhatsApp’s security standards and continued innovation under the new leadership.
MTN Nigeria has raised the bar for corporate disclosure in Africa after publishing its 2025 sustainability report in full compliance with International Financial Reporting Standards S1 and S2.
Dr. Karl Toriola, CEO of MTN Nigeria,
The report, independently assured by Ernst & Young, marks the telecom operator’s seventh consecutive annual sustainability publication and third year as an early adopter of the global framework ahead of its mandatory implementation.
Dr. Karl Toriola, CEO of MTN Nigeria, said, “strong governance and ethical conduct are foundational to our sustainability strategy. We reinforced compliance through our Conduct Passport Framework and robust internal controls.”
He added that “in May 2025, we became the first telecommunications company in Nigeria to publicly present a sustainability report on the Nigerian Exchange Group platform, an important milestone in our commitment to IFRS S1 and S2- aligned disclosure and accountability.”
The company also secured Carbon Disclosure Project ratings of ‘B-’ for climate change and ‘C’ for water security.
Under the IFRS S2 framework, the telecoms operator disclosed climate-related risks linked to flooding, heat stress, regulatory changes and possible future taxes or charges on carbon emissions, following a climate scenario analysis completed in 2024.
The report also showed that MTN Nigeria now uses a digital reporting format – XBRL. This makes its sustainability and governance data easier for investors and ESG rating agencies to access and analyse through automated systems.
The Company also carried out assessments to understand how sustainability issues affect both its business operations and society at large, while measuring its overall economic, environmental and social impact from 2021 to 2024.
In addition, over one-third of MTN Nigeria’s biggest suppliers (based on spending) have committed to supporting the company’s net-zero emissions goals, although these commitments have not yet gone through an independent audit or verification process.
