WFH drives greater cyber attack volumes

Close to 80 percent of organisations experienced cyberattacks due to more employees working from home, highlighting the vulnerabilities in legacy security technology and postures, according to research by VMware.

France saw the biggest attack increase due to home working with 96 percent seeing an upswing, while the UK (86 percent) and Australia (89 percent) also saw increased attack frequency.

Cyberattack volumes have grown, but the rapid pivot to remote working means businesses are still not seeing the full picture, it finds. Erratic employee behaviour, personal devices, and home network use reduce visibility, creating blind spots and dark corners where attacks go undetected.

In Germany, France, the US, the UK, the Nordics and Japan, ransomware was the most commonly experienced attack type.

The findings are part of the fourth installment of the Global Security Insights Report, based on an online survey of 3,542 CIOs, CTOs and CISOs in December 2020 from across the globe. 

“The race to adopt cloud technology since the start of the pandemic has created a once-in-a-generation chance for business leaders to rethink their approach to cybersecurity,” said Rick McElroy, Principal Cybersecurity Strategist, VMware.

“Legacy security systems are no longer sufficient. Organisations need protection that extends beyond endpoints to workloads to better secure data and applications. As attacker sophistication and security threats become more prevalent, we must empower defenders to detect and stop attacks, as well as implement security stacks built for a cloud-first world.”

The Global Security Insights Report provides intelligence on the cybersecurity landscape, attack and defense trends, along with the security priorities for organisations this year to maintain resilience. The key findings include:

• A lack of urgency despite surge in material breaches. 81% of respondents have suffered a breach in the last twelve months with 4 out of 5 breaches (82%) considered material. Yet, security professionals have underestimated the likelihood of a material breach. Only 56% say they fear a material breach in the next year, and just over one-third (41%) have updated their security policy and approach to mitigate the risk.
• Resurgence of ransomware and remote work creates unpredictable attack surface. 76% of respondents said attack volumes had increased – with majority pointing to employees working from home as the cause – and 79% said attacks had become more sophisticated. Cloud-based attacks were the most frequently experienced attack type in the past year, whereas the leading breach causes were third-party apps (14%) and ransomware (14%).
• Cloud-first security strategies are now universal. 98% of respondents already use or plan to use a cloud-first security strategy. But the move to cloud has expanded the threat surface. Nearly two thirds (61%) agree they need to view security differently now that the attack surface has expanded. 43% of respondents said they plan to build more security into their infrastructure and apps and reduce the number of point solutions.
• Applications and workloads are top CISO concerns. Applications and workloads are viewed as the most vulnerable points on the data journey. 63% of respondents agree they need better visibility over data and apps in order to pre-empt attacks. 60% of respondents also shared that their senior leadership team feel increasingly worried about bringing new applications to market because of the growing threat and damage of cyberattacks.
• Security concerns are holding back adoption of AI. The next frontier for business innovation may be artificial intelligence, but more than half of respondents (56%) say that security concerns are holding them back from embracing AI and machine learning.

The pandemic and shift to anywhere work have undoubtedly changed the threat landscape requiring security teams to transform their cybersecurity strategies and stay one step ahead of attackers.

Key focus areas for the coming year must include improving visibility into all endpoints and workloads, responding to the resurgence of ransomware, delivering security as a distributed service, and adopting an intrinsic approach to cloud-first security.
