Increase in Ransomware Attacks and Human Error as Main Cause of Cloud Data Breaches – 2023 Thales Data Threat

Thales announced the release of 2023 Thales Data Threat Report, its annual report on the latest data security threats, trends and emerging topics based on a survey of nearly 3000 IT and security professionals in 18 countries. This year’s report found an increase in ransomware attacks, and increased risks to sensitive data in the cloud.

Nearly half (47%) of IT professionals surveyed believe that security threats are increasing in volume or severity with 48% reporting an increase in ransomware attacks. More than a third (37%) have experienced a data breach in the past 12 months, including 22% reporting that their organisation had been a victim of a ransomware attack, the company said in an April 18 release.

Respondents identified their cloud assets as the biggest targets for cyber-attacks. Over a quarter (28%) said SaaS apps and cloud-based storage were the biggest targets, followed by cloud-hosted applications (26%) and cloud infrastructure management (25%).

The increase in cloud exploitation and attacks is directly due to the increase in workloads moving to the cloud as 75% of respondents said 40% of data stored in the cloud is now classified as sensitive compared to 49% of respondents in 2022.

These are just a few of the key insights from the 2023 Thales Data Threat Report, conducted by 451 Research, which surveyed both private and public sector organisations. It reveals how businesses are responding and planning their data security strategies and practices in light of a changing threat landscape and the progress they are making to address threats.

Human error and the impact of ransomware

Simple human error, misconfiguration or other mistakes can accidentally lead to breaches – and respondents identified this as the leading cause of cloud data breaches. For those organisations that have suffered a data breach in the past 12 months, misconfiguration or human error was the primary cause identified by 55% of respondents.

This was followed by the exploitation of a known vulnerability (21%), and of a zero day / previously unknown vulnerability (13%). The report finds that identity and access management (IAM) is the best defence, with 28% of respondents identifying it as the most effective tool to mitigate these risks.

Meanwhile, the severity of ransomware attacks appears to be declining, with 35% of 2023 respondents reporting that ransomware had a significant impact compared to 44% of respondents reporting similar levels of impact in 2022.

Spend is moving in the right direction too, with 61% reporting they would shift or add a budget for ransomware tools to prevent future attacks – up from 57% in 2022 – yet organisational responses to ransomware remain inconsistent. Only 49% of enterprises reported having a formal response ransomware plan, while 67% still report data loss from ransomware attacks.

Addressing the challenges of digital sovereignty

Digital sovereignty is becoming more top of mind for data privacy and security teams. Overall, the report found that data sovereignty remains both a short- and long-term challenge for enterprises. 83% expressed concerns over data sovereignty, and 55% agreed that data privacy and compliance in the cloud has become more difficult, likely due to emergence of requirements around digital sovereignty.

Emerging threats from quantum computers that could attack classical encryption schemes are also a cause for concern for organisations. The report found that Harvest Now, Decrypt Later (“HNDL”) and future network decryption were the greatest security concerns from quantum computing – with 62% and 55% reporting concerns respectively.

While Post Quantum Cryptography (PQC) has emerged as a discipline to counter these threats, the report found that 62% of organisations have five or more key management systems, presenting a challenge for PQC and crypto agility.

Sebastien Cano, Senior Vice President for Cloud Protection and Licensing activities at Thales, comments: “Enterprises continue to see a serious threat landscape. Our findings indicate good progress is being made in certain areas, including MFA adoption and increased use of data encryption. However, there is still a lot of security gaps regarding data visibility. In an increasingly cloud-first world, organisations must maintain better control over their data so they can serve their stakeholders with greater safety and trust. As data sovereignty and protection regulations around the world tighten, security teams will need far more confidence in protecting where their data is being stored and how it is moving and being used.”

About the 2023 Thales Global Data Threat Report

The 2023 Thales Global Data Threat Report was based on a global 451 Research survey commissioned by Thales of almost 3000 executives with responsibility for or influence over IT and data security.

Respondents were from 18 countries: Australia, Brazil, Canada, France, Germany, Hong Kong, India, Italy, Japan, Mexico, Netherlands, New Zealand, Singapore, South Korea, Sweden, the United Arab Emirates, the United Kingdom, and the United States.

Organisations represented a range of industries, with a primary emphasis on healthcare, financial services, retail, technology, and federal government. Job titles ranged from C-level executives including CEO, CFO, Chief Data Officer, CISO, Chief Data Scientist, and Chief Risk Officer, to SVP/VP, IT Administrator, Security Analyst, Security Engineer, and Systems Administrator.

Respondents represented a broad range of organizational sizes, with the majority ranging from 500 to 10,000 employees. The survey was conducted in November and December 2022. –thales/adj/mhi (Pix: Thales)
