Sophos today released its annual “State of Ransomware 2023” report, which found that the rate of ransomware attacks has increased in India with 73% of organizations surveyed reporting they were a victim of ransomware up from 57% the previous year. In 77% of ransomware attacks against surveyed organizations, adversaries succeeded in encrypting data with 44% paying the ransom to get their data back – a considerable drop from last year’s rate of 78%.  

On a global scale, the survey also shows that when organizations paid a ransom to get their data decrypted, they ended up additionally doubling their recovery costs (US$750,000 in recovery costs versusUS$375,000 for organizations that used backups to get data back). Moreover, paying the ransom usually meant longer recovery times, with45% of those organizations that used backups recovering within a week, compared to 39% of those that paid the ransom. 

“Although dipping slightly from the previous year, the rateof encryption remains high at 77 per cent, which is certainly concerning. Ransomware crews have been refiningtheir 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 35% of cases), followed by compromised credentials (involved in 33% of cases). This is in line with recent, in-the-field incident responsefindings from Sophos’ 2023 Active Adversary Report for Business Leaders. 

“With almost three quarters of Indian organizations reporting that they have been victimized by ransomware criminals, a lot of work needs to be done. 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 quarter who stay safe and the three quarters 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:
    • 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 
    • Adaptive technologies that respond automatically to attacks, disrupting adversaries and buying defenders time to respond 
    • 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 and Japan. Organizations surveyed had between 100 and 5,000 employees, and revenue ranged from less than $10 million to more than $5 billion.
