Sophos Survey Shows Increase in Ransomware Attacks on Education Institutions

Education Sector Suffers Highest Data Encryption Rate and Longest Recovery Time

Sophos - The State of Ransomware in Education 2022

Sophos, a global leader in next-generation cybersecurity, has published a new sectoral survey report, The State of Ransomware in Education 2022.

 Sophos, a global leader in next-generation cybersecurity, has published a new sectoral survey report, The State of Ransomware in Education 2022.

The findings reveal that education institutions – both higher and lower education – are increasingly being hit with ransomware, with 60% suffering attacks in 2021 compared to 44% in 2020.

Education institutions faced the highest data encryption rate (73%) compared to other sectors (65%), and the longest recovery time, with 7% taking at least three months to recover – almost double the average time for other sectors (4%).

Other key findings include:

  • Education institutions report the highest propensity to experience operational and commercial impacts from ransomware attacks compared to other sectors; 97% of higher education and 94% of lower education respondents say attacks impacted their ability to operate, while 96% of higher education and 92% of lower education respondents in the private sector further report business and revenue loss
  • Only 2% of education institutions recovered all of their encrypted data after paying a ransom (down from 4% in 2020); schools, on average, were able to recover 62% of encrypted data after paying ransoms (down from 68% in 2020)
  • Higher education institutions in particular report the longest ransomware recovery time; while 40% say it takes at least one month to recover (20% for other sectors), 9% report it takes three to six months

“Schools are among those being hit the hardest by ransomware. They’re prime targets for attackers because of their overall lack of strong cybersecurity defenses and the goldmine of personal data they hold,” said Chester Wisniewski, principal research scientist at Sophos. “Education institutions are less likely than others to detect in-progress attacks, which naturally leads to higher attack success and encryption rates. Considering the encrypted data is most likely confidential student records, the impact is far greater than what most industries would experience. Even if a portion of the data is restored, there is no guarantee what data the attackers will return, and, even then, the damage is already done, further burdening the victimized schools with high recovery costs and sometimes even bankruptcy. Unfortunately, these attacks are not going to stop, so the only way to get ahead is to prioritize building up anti-ransomware defenses to identify and mitigate attacks before encryption is possible.”

Interestingly, education institutions report the highest rate of cyber insurance payout on ransomware claims (100% higher education, 99% lower education).

However, as a whole, the sector has one of the lowest rates of cyber insurance coverage against ransomware (78% compared to 83% for other sectors).

“Four out of 10 schools say fewer insurance providers are offering them coverage, while nearly half (49%) report that the level of cybersecurity they need to qualify for coverage has gone up,” said Wisniewski.

“Cyber insurance providers are becoming more selective when it comes to accepting customers, and education organizations need help to meet these higher standards. With limited budgets, schools should work closely with trusted security professionals to ensure that resources are being allocated toward the right solutions that will deliver the best security outcomes and also help meet insurance standards,” he added.

In the light of the survey findings, Sophos experts recommend the following best practices for all organizations across all sectors:

  • Install and maintain high-quality defenses across all points in the environment. Review security controls regularly and make sure they continue to meet the organization’s needs
  • Proactively hunt for threats to identify and stop adversaries before they can execute attacks – if the team lacks the time or skills to do this in-house, outsource to a Managed Detection and Response (MDR) team
  • Harden the IT environment by searching for and closing key security gaps: unpatched devices, unprotected machines and open RDP ports, for example. Extended Detection and Response (XDR) solutions are ideal for this purpose
  • Prepare for the worst, and have an updated plan in place of a worst-case incident scenario
  • Make backups, and practice restoring from them to ensure minimize disruption and recovery time

The State of Ransomware in Education 2022 survey polled 5,600 IT professionals, including 320 lower education respondents and 410 high education respondents, in mid-sized organizations (100-5,000 employees) across 31 countries.

Only 26% of Surveyed Organizations Stopped Data Encryption by Cybercriminals – Sophos

Retail organizations attacked by ransomware increasingly unable to halt an attack in progress, Sophos Survey Finds, writes SANDRA ANI

Sophos The State of Ransomware in Retail 2023
  • This Is the Lowest Rate of Disruption in 3 Years  

Sophos, a global leader in innovating and delivering cybersecurity as a service, today shared findings from its sector survey report, “The State of Ransomware in Retail 2023,” which found that only 26% of retail organizations this past year were able to disrupt a ransomware attack before their data was encrypted.

Sophos, a global leader in innovating and delivering cybersecurity as a service, today shared findings from its sector survey report, “The State of Ransomware in Retail 2023,” which found that only 26% of retail organizations this past year were able to disrupt a ransomware attack before their data was encrypted.

This is a three-year low for the sector—a decline from 34% in 2021 and 28% in 2022—suggesting the sector is increasingly unable to halt ransomware attacks already in progress.

“Retailers are losing ground in the battle against ransomware. Ransomware criminals have been encrypting increasingly greater percentages of their retail victims in the last three years, as evidenced by the steadily declining rate of retailers stopping cybercriminal attacks in progress. Retailers must up their defensive game by setting up security that detects and responds to intrusions earlier in the attack chain,” said Chester Wisniewski, director, global field CTO, Sophos.

In addition, the report found that, for those retail organizations that paid the ransom, their median recovery costs (not including the ransom payment) were four times the recovery costs of those that used backups to recover their data ($3,000,000 versus $750,000).

“Forty-three percent of retail victims paid the ransom according to our survey respondents, yet the median recovery cost to victims who paid the ransom was four times the cost to those who used backups and other recovery methods. There are no shortcuts in these situations and rebuilding systems is almost always required. It’s better to deprive the criminals of their spoils and build back better,” said Wisniewski.

Additional key findings from the report include:

  • In line with a broader, cross-sector trend, the retail sector experienced its highest rate of encryption over the past three years, with 71% of those organizations targeted by ransomware stating that attackers successfully encrypted their data
  • The percentage of retail organizations attacked by ransomware declined from 77% last year to 69% this year
  • The percentage of retail organizations that recovered in less than a day decreased from 15% to 9% this year, while the percentage of retail organizations that took more than a month to recover increased from 17% to 21%

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
    • Adaptive technologies that respond automatically to attacks, disrupting adversaries and buying defenders time to respond
  • 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

The State of Ransomware 2023 survey polled 3,000 IT/cybersecurity leaders in organizations with between 100 and 5,000 employees, including 355 from the retail sector, across 14 countries in the Americas, EMEA and Asia Pacific.
