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

Adefolarin Ogunsanya, company’s, board chairman, explained in a statement that Osi would succeed Oladipo Badru, whose tenure lasted nine months in acting CEO position. Osi has more than 28 years of experience in the telecommunications sector across various regions of Africa.
Prior to his appointment as CEO, he had served as the head of network deployment at Airtel Nigeria, operations director and chief technical information officer at MIC Tanzania, chief technology officer roles at IPT PowerTech Nigeria, Rhino Niger Networks and Biswal Nigeria.
He obtained a degree in electrical/ electronic engineering from the University of Benin and a postgraduate diploma in data science and business analytics from the University of Texas.
Companies sending bulk international text messages, also known as Application-to-Person (A2P) messages, will now have apply for a licence that costs N10 million.
This is part of new rules introduced by the Nigerian Communications Commission (NCC) aimed at cleaning up the system, fighting fraud, blocking spam messages and stopping money from leaving the country unchecked.
These A2P messages are the kind customers get from banks, online stores, hospitals and political campaigns, automated texts sent from apps to their phones.
According to the commission, the bulk international text message system has been poorly regulated, allowing misuse and invasion of privacy.
“The International SMS Service Ecosystem in Nigeria has not been fully brought under regulatory control. It has been observed that the excessive use of the Short Message Service has led to fraud, spam and illegal activities,” the NCC said.
The regulator warned that without action, the problem would worsen as more people use mobile phones and digital services.
To solve this, the NCC is creating a central platform, or gateway, through which all international bulk text messages must pass through.
The agency said this would help to monitor messages in real time, ensure proper fees are paid, and make sure the money stays in Nigeria where it can contribute to the economy.
As part of the incoming change, service providers must follow strict rules, including strong data protection, spam filters, and message encryption.
Also, they must also work with local mobile networks and make sure all messages come from a verified sender
The NCC warned that any message without a proper sender ID will be blocked and not delivered to users.
To protect users from unwanted texts, the new rules say companies must get clear permission before sending any promotional content.
The rule also says people must also be able to choose whether they want to receive such messages or not.
Companies are now required to keep records of all messages for at least six months and must clearly state all charges involved.
The NCC said fees for help requests, cancellations, or service info must be transparent and not include hidden charges.
The commission will issue licences to several providers to encourage healthy competition but may limit new licences if needed.
Only companies that show they can stop fraud and safely deliver messages will be allowed to operate. They must also regularly report their message traffic and finances to the NCC.
It warned that any company that breaks the rules risks getting fined, suspended, or having its licence revoked.
Offences like charging illegal tariffs, ignoring security rules, or avoiding taxes will be punished, the NCC said.
The commission added that the new rules follow the Nigerian Data Protection Act 2023 and support the federal government’s goal of strengthening cybersecurity and controlling Nigeria’s digital space.
The framework will also be reviewed from time to time to keep up with new technology and market trends.
MTN Nigeria has launched what it claims is the country’s largest prefabricated modular data centre, marking a bold push into the country’s fast-growing cloud market and taking aim at global giants such as Amazon Web Services, Microsoft Azure and Google Cloud.

The shift comes as demand for cloud services in Nigeria soars — driven by the uptake of mobile apps, fintech tools and e-learning platforms — while foreign providers have become costlier in the wake of the naira’s sharp devaluation.
“This is one of the biggest data centres in West Africa and probably one of the biggest in Africa,” said Karl Toriola, CEO, MTN Nigeria.
He described the new Tier III-certified facility, with locally hosted cloud services, as “transformative for the technology ecosystem in Nigeria and very supportive of the federal government’s agenda”.
MTN Nigeria, the country’s largest telecoms provider, has so far invested $120m in the first phase, delivering an IT load of 4.5MW. A second phase, set to double capacity to 9MW, is budgeted at $135m.
“We already have data centres that are running our existing capacities,” Toriola said.
“We will go to 9MW in short order, possibly 14MW, and we can expand even further.”
He said the facility would allow local hosting for tech developers, large enterprises including banks and oil companies, and government agencies — markets long dominated by foreign cloud providers.
“Multinational companies such as Netflix, Facebook and Instagram can also host a lot of their data here. That improves the quality of service and reduces the cost of storage,” he added.
