Ransomware: from crisis to comeback

Ross Brewer at Graylog describes how to rebuild trust after a ransomware attack

 

In the digital age, trust is currency, and ransomware is its most insidious thief. Ransomware has evolved from a blunt instrument into a precision weapon. Today’s attackers are no longer lone opportunists but part of highly sophisticated and well-funded operations. They exploit legitimate tools, can mimic administrative behaviour, and often dwell undetected in networks for weeks. It’s often typical that by the time the ransom note appears, the damage is already done, not just to systems, but to reputations.

 

For organisations, the question is no longer if they will be targeted, but when. The Government’s Cyber Security Breaches Survey 2025 reveals that over four in ten businesses (43%) has reported having experienced any kind of cyber-security breach or attack in the last 12 months. Only when that moment arrives does the real test begin - not just in the security operation centre (SOC), but in the boardroom and the public eye.

 

 

The first 48 hours: containment and communication

The immediate response to a ransomware attack must be decisive. Isolating affected systems, activating the incident response plan, and bringing in external expertise is paramount. While technical teams work to contain the breach, leadership must direct their attention to communicating the breach accurately to a company’s stakeholders.

 

This is the point at which many organisations falter. The instinct to go silent, to “wait until we know more”, is understandable, but highly dangerous. In today’s hyper-connected world, silence equals suspicion. Stakeholders will fill the vacuum with speculation, misinformation, and doubt. In some cases executives act too quickly and go public on limited information which can lead to over-disclosure. A well-managed PR and communications plan can help get the right message to the right people at the right time.

 

 It’s essential to communicate early, clearly, and consistently and with transparency. This communication must acknowledge the incident, outline what is known, and commit to regular updates. If a business is attacked and has no communication strategy in place, it can amplify concern and reputational damage to the organisation. While people might not always expect perfection, they do expect honesty.

 

 

Taking control of the narrative

The ripple effects of a successful ransomware attack can extend far beyond IT systems. For this reason, it’s important to control the narrative and understand five key considerations to ensuring all stakeholders are engaged:

• The human touch: By personalising outreach and offering tangible support, this will reassure customers and the supply chain that their safety and peace of mind are a priority.
• Involve senior leaders: leadership visibility is another cornerstone of effective narrative control. When senior executives speak directly to the public, it signals accountability and seriousness. Their presence humanises the organisation and reinforces the message that the incident is being handled at the highest levels.
• Undertake a post-incident review: Accountability and learning from the experience can improve processes, which is key to regaining trust. A thorough, independent post-incident review not only explores and identifies what went wrong but also demonstrates a commitment to learning and improving processes. This also sets a precedent for continuous improvement and responsible governance.
• Keep employees informed: Internally, organisations must also manage the information shared among its biggest allies – it’s employees - who are both recipients and vectors of information. Keeping them informed through internal briefings, FAQs, and direct communication channels reduces the risk of leaks and speculation. With the right information they are empowered to act as ambassadors of the brand during a sensitive time.
• Undertake audience segmentation: Not all stakeholders require the same information, nor do they process risk in the same way. Customers, employees, regulators, investors, and the media each have distinct concerns and expectations. A truly effective communication strategy tailors messaging to each group, balancing transparency with relevance.

 

Proactive strategies for recovery and future resilience

The consequences of a sustained cyber-attack are many and variable. The bottom line is that reputation, once compromised, cannot be easily restored through a single gesture or statement. This situation demands a sustained, multidimensional effort that extends far beyond technical remediation.

 

Recovery must be sustained at a tactical level through ongoing updates on security enhancements. However, to stay ahead of the evolving ransomware threat, organisations need to take a holistic approach to their defence strategies, in adopting comprehensive security frameworks such as Zero Trust Architecture.

 

A Zero Trust approach assumes no implicit trust and requires continuous verification of all users and devices. Implementing advanced threat detection and response systems, regular security training for employees, and robust backup solutions are also essential. Additionally, leveraging AI and machine learning to identify and mitigate threats in real-time can significantly enhance an organisation’s security posture.

 

Backups should be encrypted, stored offline or in immutable formats, and regularly tested for integrity, as modern ransomware groups often target backup repositories to sabotage recovery efforts. Continuous monitoring through Security Information and Event Management (SIEM) platforms enables real-time threat detection and response, which is essential to stop a threat in its tracks.

 

 

Creating a culture of cyber-security

Ultimately, elevating the level of cyber-security education and vigilance throughout the business is key to building robust defences. Cyber-security must be embedded into organisational culture through regular training, phishing simulations, incident response rehearsals and executive-level engagement. These measures, taken together, transform cyber-security from a reactive function into a proactive, strategic capability. It also requires a shift in mindset, from reactive compliance to proactive resilience.

 

Rebuilding reputation isn’t achieved overnight; it requires consistent, authentic engagement and a clear roadmap for recovery that puts security, trust, and customer reassurance at the centre.
