Ransomware Attacks Reaches Highest Level as 66% of Organisations Surveyed fell Victim to adversaries – Sophos Report
Sophos, a global leader in innovating and delivering cybersecurity as a service, has released its annual “State of Ransomware 2023[LS1] ” 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:
o 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
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 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.
Lebara Nigeria has become a member of the Global System for Mobile Communications Association (GSMA) as it expands operations in the West African country.
The membership places Lebara Nigeria within a global network of more than 1,000 mobile operators, device manufacturers, technology companies and digital service providers.
Through the GSMA, the company will have access to industry research, technical standards, policy engagement and industry initiatives.
Lebara Nigeria said the move reflects its participation in the wider telecommunications ecosystem as it develops its operations in Nigeria’s mobile market.
Nigeria’s telecommunications sector plays a central role in the country’s digital economy, with more than 170 million active mobile subscriptions supporting services such as digital payments, e-commerce, education and healthcare.
Industry analysts say participation in international bodies such as the GSMA supports knowledge sharing and the adoption of industry standards.
Lebara Nigeria said GSMA membership will support its engagement with industry developments and policy discussions in the telecommunications sector.
The company said it remains focused on operating in Nigeria’s mobile telecommunications market as demand for connectivity continues to grow.
GSM Association is the advocacy and lobbying organization for the mobile communications industry, representing more than 1,000 mobile operators as full members and a further 400 companies in the broader mobile ecosystem as associate members.
Management of Vitel Wireless, mobile virtual network operator (MVNO), has distanced the company from a fraudulent scheme operating under the name: “Vitel Shares Services.”
In an official statement, the management clarified that Vitel Wireless is not selling shares or running any investment schemes.
They warned that the operators of “Vitel Shares Services” are using unauthorised websites, mobile applications, social media promotions, and bank accounts falsely linked to Vitel Wireless to mislead the public.
The statement reads: “The attention of Vitel Wireless has been drawn to a fraudulent scheme operating under the name ‘Vitel Shares Services.’
“We wish to state clearly that Vitel Wireless has no affiliation with Vitel Shares Services, or any platform claiming to offer Vitel shares, investments, or financial products through unofficial channels.
“We do not solicit investments through agents, social media, websites, apps, or third parties. Any platform claiming to offer Vitel Wireless shares or investments outside our official channels is fraudulent and should be treated as such.
“We urge the general public to remain vigilant and verify all information through official Vitel Wireless communication channels before making any payments or sharing personal data.”
Airtel Nigeria has concluded its second Customer Forum in Abuja, bringing together a large section of customers including high-volume data subscribers, 5G customers, and key stakeholders in another landmark engagement aimed at addressing concerns around data usage, transparency, and customer experience.
The forum themed “Understanding Your Data and Taking Control 2.0.” aimed to strengthen trust in Nigeria’s rapidly evolving telecommunications landscape. The session also featured inputs from representatives of the Nigerian Communications Commission (NCC).
Delivering the Keynote remarks, Dinesh Balsingh, CEO of Airtel Nigeria, who was represented by Femi Adeniran, Director, Corporate Communications and CSR, emphasised that trust remains the most valuable currency in telecommunications, and Airtel remains committed to strengthening customer confidence through transparency and continuous engagement.
He explained that discussions around data consumption have become increasingly important as digital lifestyles evolve, with smartphones, cloud services, video streaming and emerging artificial intelligence applications significantly influencing data usage patterns.
According to him, Airtel recently introduced the Airtel Data Calculator, an innovative tool designed to help customers estimate their data needs based on online activities such as multimedia streaming, video calls, social media usage, and gaming.
“The purpose of the Airtel Data Calculator is to provide greater visibility, support informed decision-making and place more information directly in the hands of customers. Because transparency should never be viewed as a compliance exercise. Transparency is good business,” he stated.
He further reassured customers that Airtel has no incentive to shortchange subscribers through inaccurate billing, forced spending or unnecessary data depletion, stressing that the company’s growth depends on customer satisfaction, loyalty and trust.
Adeniran also highlighted Airtel’s continued investments in network infrastructure, fibre capacity, digital platforms, artificial intelligence capabilities, customer service systems and workforce development, noting that these investments are aimed at improving service quality and enhancing customer experiences.
Oladokun Oye, Director, Customer Experience, Airtel Nigeria, while welcoming participants to the event, said the forum was created to provide customers with an open platform for education, engagement and problem-solving, noting that the customer remains at the centre of Airtel’s business.
“Data has become central to everyday life, powering work, education, commerce, entertainment, healthcare and countless opportunities. As data usage grows, so too does the desire for greater visibility and understanding.
Today’s conversation is part of an ongoing journey. A journey toward greater transparency. A journey toward deeper understanding. And a journey toward a better customer experience for every Airtel subscriber,” he said.
The forum also featured practical demonstrations on data consumption management, device settings, and usage habits that impact data usage. It also included an interactive session by which Airtel teams provided clarifications and offered feedback to customers.
The Abuja event follows the successful maiden edition held earlier this year in Lagos and aligns with broader industry efforts led by the Nigerian Communications Commission (NCC) to improve consumer awareness, transparency, and confidence within the telecommunications sector.
