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.
Four people have been killed, with over 20 injured after a fire at Cairo data centre disrupted telecom services nationwide.
A fire at a major Telecom Egypt facility in Cairo on Monday has left four workers dead and at least 22 others injured, plunging parts of the capital into a communications crisis.
According to Hossam Abdel Ghaffar, spokesperson for Egypt’s Health Ministry, most injuries were due to smoke inhalation.
The blaze, which broke out at a key data centre operated by Telecom Egypt, the country’s primary fixed-line and internet provider, was brought under control later that day.
However, it caused widespread disruptions, halting phone services, affecting internet connectivity, and even interfering with digital banking operations.
Internet monitoring group NetBlocks reported that national connectivity dropped to just 62% of normal levels following the incident.
Residents across Cairo struggled with poor network access, and banks—although already closed for the day—reported interruptions in ATM services and online transactions.
In a statement on Tuesday, Telecom Egypt mourned the loss of its employees and pledged support to their families.
Amr Talaat, Egypt’s minister of Communications and Information Technology, assured the public that service restoration was underway and expected to be completed within 24 hours.
To address the disruption, the Health Ministry released alternative emergency contact numbers across Egypt’s governorates, in case its primary ambulance hotline remained unreachable.
The state-run MENA news agency reported that the fire was prevented from engulfing the entire building and nearby rooftops, thanks to the efforts of emergency responders.
A preliminary investigation suggests the fire was likely triggered by an electrical short circuit, according to a security source cited by MENA.
As the nation works to restore full connectivity, the incident has raised fresh concerns about the vulnerability of critical infrastructure and the need for enhanced fire safety protocols in sensitive tech facilities.

The Stakeholders in Blockchain Technology Association of Nigeria (SiBAN) has lauded Interstellar, one of its prominent members, for spearheading a major breakthrough in Africa’s financial technology space.
This follows Interstellar’s strategic partnership with the Pan-African Payment and Settlement System (PAPSS) to roll out the PAPSS African Currency Marketplace (PACM), a blockchain-based platform designed to address the continent’s long-standing currency inconvertibility challenge.
The initiative is already being hailed as a game-changer capable of eliminating the $5 billion annual trade friction currently plaguing intra-African commerce.
According to SiBAN President, Mr Obinna Iwuno, the development affirms Nigeria’s leadership in blockchain innovation, stating that Interstellar’s PACM is not only a technological feat but also a timely response to the African Continental Free Trade Area (AfCFTA) mandate of seamless and cost-effective regional trade.
PACM operates on STARGATE, a blockchain-agnostic system developed by Interstellar, and leverages the Bantu blockchain network to facilitate real-time, peer-to-peer exchanges of African currencies.
The solution ensures financial inclusion by allowing businesses, SMEs, and informal traders to transact in local currencies without relying on foreign intermediaries, all while maintaining regulatory compliance.
Mr Ernest Mbenkum, CEO of Interstellar, described the solution as Africa’s roadmap to financial sovereignty. “Blockchain is not just innovation; it is empowerment,” he said.
SiBAN reaffirmed its commitment to supporting policies and partnerships that promote secure, transparent, and inclusive digital economies.
The association further called on stakeholders in government and the private sector to prioritise blockchain adoption as a driver of national development.
