Ransomware Preparedness must become a strategic priority for organizations as cyberattacks grow more disruptive and difficult to contain, according to Richard Horne, CEO of the UK's NCSC (National Cyber Security Centre). Speaking during the FBI's Ahead of the Threat podcast, Horne urged business leaders to assess whether their organizations could continue operating if critical IT systems were unavailable for four weeks. His remarks come amid growing concerns over ransomware, AI-driven cyber threats, and the increasing speed at which attackers exploit known vulnerabilities.

Ransomware Preparedness Requires Planning Beyond Paying a Ransom

A key message from Horne was that organizations should not view ransom payments as a recovery strategy. Instead, effective Ransomware Preparedness depends on resilience, tested recovery plans, and executive support. According to Horne, ransomware attacks typically involve two forms of extortion. Attackers steal sensitive data and threaten to publish it, while also encrypting systems and demanding payment for decryption keys. He noted that paying criminals does not guarantee data will be deleted or systems fully restored. Referencing lessons learned from Operation Cronos, the international law enforcement operation that disrupted the LockBit ransomware group, Horne said investigators found instances where victim data remained on criminal infrastructure even after ransom payments had been made.

NCSC Warns Organizations About the Coming Patch Wave

The discussion also highlighted concerns about a growing Patch Wave, a term used by the NCSC to describe the anticipated surge in vulnerability disclosures and exploitation attempts fueled by artificial intelligence. FBI Cyber Division Assistant Director Brett Leatherman pointed to recent industry findings showing that attackers are exploiting known vulnerabilities faster than defenders can remediate them. Internet-facing devices and VPNs have become increasingly attractive targets, while the window between disclosure and exploitation continues to shrink. Horne stressed that organizations need long-term planning rather than short-term reactions. He encouraged businesses to develop multi-year cybersecurity roadmaps and ensure security investments remain a priority across budget cycles.

CyberUK Discussions Focused on Executive Accountability

Reflecting on discussions held during CyberUK, the UK's flagship cybersecurity conference hosted by the NCSC, Horne emphasized that cybersecurity cannot remain solely the responsibility of technical teams. He noted that many Chief Information Security Officers face challenges securing organizational support despite having visibility into technology risks. According to Horne, leadership teams must actively participate in managing cyber risk rather than treating it as an isolated IT issue. The conversation also addressed burnout among cybersecurity professionals, with both Horne and FBI officials acknowledging the operational strain placed on defenders during major incidents, including ransomware attacks and large-scale vulnerability disclosures.

Public-Private Cooperation Remains Critical

Beyond technical defenses, Horne highlighted the importance of collaboration between governments, law enforcement agencies, and the private sector. He said threat intelligence sharing creates a continuous cycle in which organizations identify threats, share findings, improve defenses, and generate new intelligence that benefits the wider cybersecurity community. Horne also pointed to growing opportunities to use artificial intelligence to accelerate threat detection and response efforts. As ransomware groups continue targeting businesses worldwide, the message from both the FBI and the NCSC was clear: organizations must invest in Ransomware Preparedness, strengthen resilience plans, and prepare for a future where cyber incidents are not a possibility but an expectation.

Organisations worldwide are being urged to prepare for a vulnerability patch wave, as security experts warn that advances in artificial intelligence (AI) could rapidly expose long-standing weaknesses across software systems. The warning comes from National Cyber Security Centre (NCSC), which says businesses must act now to strengthen their environments before a surge of critical updates arrives. In a blog, Chief Technology Officer Ollie Whitehouse highlighted that years of accumulated technical debt are now becoming a major cybersecurity risk. Technical debt refers to unresolved flaws and compromises in software that arise when organisations prioritise speed or short-term delivery over long-term resilience. According to Whitehouse, artificial intelligence is accelerating the problem. Skilled attackers are increasingly able to use AI tools to identify and exploit vulnerabilities at scale, forcing what the NCSC describes as a “correction” across the technology ecosystem. This is expected to trigger a vulnerability patch wave, with a high volume of security updates affecting open source, commercial, proprietary, and software-as-a-service platforms.

Prioritising External Attack Surfaces

As part of preparing for the vulnerability patch wave, the NCSC advises organisations to first focus on their external attack surfaces. Internet-facing systems, cloud services, and exposed infrastructure present the highest risk when new vulnerabilities are disclosed. The guidance recommends a perimeter-first approach. Organisations should secure outward-facing technologies before moving deeper into internal systems. This reduces the likelihood that attackers can exploit newly discovered weaknesses during the vulnerability patch wave. Where resources are limited, priority should be given to patching systems that are directly exposed to the internet. Critical security infrastructure should follow next. However, the NCSC cautions that patching alone will not solve every issue. Legacy and end-of-life systems remain a major concern. Many of these technologies no longer receive security updates, leaving organisations vulnerable even during a vulnerability patch wave. In such cases, businesses may need to replace outdated systems or bring them back into supported environments, especially if they are externally accessible.

Preparing for Faster and Large-scale Patching

The expected vulnerability patch wave will require organisations to rethink how they manage updates. The NCSC is urging businesses to prepare for faster, more frequent, and large-scale deployment of security patches, including across supply chains. Several key measures have been recommended:

• Enable automatic updates wherever possible to reduce operational burden
• Adopt secure “hot patching” to apply fixes without service disruption
• Ensure internal processes support rapid and large-scale updates
• Use risk-based prioritisation models such as Stakeholder Specific Vulnerability Categorisation (SSVC)

Whitehouse noted that organisations must be ready to accelerate patching timelines when critical vulnerabilities are actively exploited, particularly those affecting internet-facing systems. At the core of this approach is an “update by default” policy. This means applying software updates as quickly as possible, ideally through automated processes. While this may not always be feasible for safety-critical or operational technology systems, the NCSC says it should form the foundation of modern vulnerability management strategies.

Beyond Vulnerability Patch Wave: Addressing Systemic Risks

The NCSC emphasises that the vulnerability patch wave is only part of a broader cybersecurity challenge. Patching addresses immediate risks, but it does not eliminate the underlying causes of technical debt. Technology vendors are being encouraged to build more secure systems from the outset. This includes adopting memory safety and containment technologies such as CHERI, which can reduce the likelihood of exploitable vulnerabilities. For organisations operating critical services, strengthening cybersecurity fundamentals is equally important. Frameworks such as Cyber Essentials and sector-specific resilience models can help reduce the impact of breaches and improve overall security posture. Additional guidance has also been issued for high-risk environments, covering areas such as privileged access workstations, cross-domain security architecture, and threat detection through observability and proactive hunting.

Organisations Urged to Act Now

The NCSC has made it clear that preparation cannot be delayed. The anticipated vulnerability patch wave is expected to impact organisations of all sizes and sectors. Businesses are advised to review their vulnerability management processes, assess their exposure, and ensure their supply chains are also ready to respond. Larger organisations, in particular, are encouraged to seek assurance from both commercial and open-source partners. As Whitehouse concluded, readiness for the vulnerability patch wave will depend on proactive planning, strong fundamentals, and the ability to respond quickly at scale.
