The first 24 hours after a ransomware attack

A ransomware attack represents a major threat for any organisation in Ireland. Data from Hiscox showed that 71% of Irish businesses suffered at least one cyber attack over the last 12 months. This makes rapid, informed threat response essential. The actions you take in the first 24 hours can mean the difference between quick recovery and prolonged disruption.

Step one: confirm the attack and isolate systems. Ransomware attacks may initially seem subtle, gradually locking files or impacting systems before the full threat becomes apparent. Typical signs include inaccessible data, unusual system behaviours, or suspicious network activity. Immediate isolation is critical. Disconnect affected devices from the network, disable Wi-Fi and VPN access, and block suspicious activity at firewall levels. Swift containment can significantly reduce the severity of an attack.
Step two: notify stakeholders and assemble your response team. Effective ransomware response extends beyond IT departments. Promptly inform senior management, legal advisors, compliance officers, and communications teams. Establish a response leader to oversee coordination and decision-making. Utilise an established incident response plan if available. Clear communication and structured procedures streamline response and recovery efforts, reducing downtime and business impact.
Step three: secure backups and avoid engaging attackers. Avoid interacting directly with attackers, as this may escalate the situation or compromise recovery. Secure your backups and logs immediately, documenting the affected systems and the timeline of events. Conduct thorough forensic analysis to identify indicators of compromise (IOCs) and determine if data has been stolen or exfiltrated, a growing concern under GDPR.
Step four: report the incident and understand your legal obligations. In Ireland, GDPR regulations require reporting data breaches to the Data Protection Commission (DPC) within 72 hours. It’s crucial to promptly notify relevant regulatory bodies, industry-specific authorities, and affected customers if applicable. Ensure documentation is accurate and comprehensive. Your reports should clearly outline the scope of the breach, steps taken, and planned recovery actions.
Step five: recovery and strengthening defences. Begin recovery only once containment and forensic analysis have been thoroughly completed. Restoration involves more than reinstating data from backups; it includes removing attacker access, patching vulnerabilities, and validating systems before returning them to operation. Consider engaging with experienced cyber security professionals to assist recovery and implement preventative measures. Strengthening your cyber resilience post-incident reduces future vulnerabilities.

Importance of swift, informed action

Rapid and knowledgeable response to ransomware attacks limits operational disruption, financial losses, and reputational damage. Organisations in Ireland must prioritise preparedness, response speed, and expert guidance.

Regular training, simulated incident exercises, and clear response plans can significantly enhance readiness, ensuring your business is resilient against cyber threats.

Preparation is key

The first 24 hours of responding to a ransomware attack can be challenging. But with appropriate preparedness and robust response planning, Irish businesses can mitigate threats effectively and maintain operational stability.

What does a good cyber security incident response plan look like?

Cyber security incidents are becoming increasingly common in Ireland, with recent statistics from the Central Statistics Office indicating that over 20% of Irish enterprises have experienced cyber security breaches in the past year. Regardless of your organisation’s size, the question isn’t if you’ll face a cyber attack, but when. Therefore, developing an effective incident response (IR) plan is critical. Here’s what a comprehensive IR plan should include to protect your organisation effectively.

Key components of an effective incident response plan

Structure: clear and concise – An effective incident response plan must be easy to follow. Complexity can cause delays and confusion. Using clear language, charts, and bullet points ensures the plan can be quickly understood and executed effectively, even in stressful situations.
Utilising established frameworks – Irish organisations often adopt recognised frameworks, such as ISO 27001 or the National Institute of Standards and Technology (NIST) guidelines. These provide comprehensive, structured approaches covering governance, technical responses, and risk management. Adhering to recognised standards simplifies communications with external bodies, including regulators and cybersecurity authorities in Ireland.
Roles and responsibilities: clarity matters- An Incident Response Team (IRT), typically led by a Chief Information Security Officer (CISO) or equivalent, should be clearly identified. The IR plan must define roles and responsibilities for all stakeholders, from IT support to legal and compliance teams. Clearly defined roles help prevent overlaps and confusion during critical moments.
Budget: invest smartly – Budget considerations are vital. Allocate adequate resources to staffing, technology solutions, and ongoing training. The investment should align with the organisation’s size, complexity, and specific risk factors. In 2023, Irish businesses significantly increased their cyber security budgets in response to rising threats, indicating the seriousness of allocating adequate funding.

Detection, reporting, and identification procedures

Proactive monitoring systems – Swift detection is key. Organisations should invest in advanced threat monitoring solutions to detect incidents early. This includes round-the-clock monitoring to ensure rapid identification and response.
Simple reporting and identification – Make reporting easy and accessible. Clear reporting processes enable even non-technical staff to quickly identify and escalate incidents, significantly reducing response times.

Communication strategies: internal and external

The importance of clear communication – Clear communication strategies, managed by public relations and marketing teams, help control the narrative during incidents, minimising reputational damage. Transparent, accurate updates reassure customers and stakeholders alike.
Internal communications – Internal stakeholders, from management to frontline employees, must remain informed. Having structured communication channels ensures everyone understands their role and responsibilities during an incident.

External communications – Your IR plan should clearly outline how you communicate with external stakeholders—customers, partners, suppliers, regulators, and potentially the media. Timely and transparent external communications are critical, especially considering GDPR regulations, which mandate notifying the Data Protection Commission (DPC) within 72 hours of becoming aware of certain breaches.

Containment, eradication, and recovery guidelines

Immediate containment – The plan should specify immediate containment steps, such as isolating affected systems to limit damage and prevent further breaches.
Eradication and recovery – Clearly outline procedures for identifying the root cause and eliminating threats. Detail the recovery process to restore and verify system integrity, ensuring a smooth return to normal operations.

Training, exercises, and cyber insurance

Regular cyber exercises – Conduct regular simulated cyber attack scenarios to evaluate your plan’s effectiveness. These exercises identify potential gaps and enhance the preparedness of your incident response team.

Cyber insurance – Cyber insurance is increasingly essential, helping organisations manage costs associated with cyber incidents, including legal fees, remediation expenses, and potential regulatory fines. Clearly document when and how to activate your cyber insurance policy within your IR plan.

Dos and don’ts: best practices and pitfalls

Dos:

Regularly train all staff in cyber security awareness
Frequently review and update your IR plan
Ensure transparent communication internally and externally
Conduct thorough post-incident analyses to learn and improve

Don’ts:

Ignore early warnings or unusual activity
Underestimate the role of employee training
Fail to regularly update stakeholders
Neglect adapting your strategy based on lessons learned

Developing and maintaining a robust incident response plan helps your organisation remain resilient against cyber threats, protecting not only your operational integrity but your reputation as well.

What is deepfake social engineering and how can businesses in Ireland defend against it?

Deepfake technology is advancing rapidly, and with it comes an evolving cyber threat landscape. In Ireland, where digital transformation continues to accelerate, businesses are increasingly exposed to sophisticated forms of social engineering powered by artificial intelligence. One such threat is deepfake social engineering—a method that uses AI-generated audio, video, or images to impersonate individuals and deceive employees into taking harmful actions.

How deepfake social engineering works

Deepfake social engineering leverages realistic digital impersonations to manipulate human trust. Attackers use AI to mimic voices, faces, or even full video personas, often impersonating executives or trusted contacts. Common tactics include:

Voice fraud and BEC: Impersonating a CEO or finance director via cloned audio to request wire transfers or sensitive data.
Fake video calls: Using video deepfakes to simulate a meeting with a senior leader, asking for urgent and confidential actions.
Reputation damage: Spreading fake videos of executives making controversial statements to harm brand reputation or stock value.
Phishing with a twist: Using realistic images or video to manipulate staff into revealing credentials or bypassing standard procedures.

Commonly used deepfake tools

Cybercriminals misuse a variety of tools to execute these attacks:

DeepFaceLab, Zao, and FaceSwap: Used for realistic face-swapping in videos.
Respeecher and ElevenLabs: For creating near-perfect voice clones.
Synthesia and Hedra: Capable of generating lifelike AI avatars and syncing cloned audio to images or video.

These tools have legitimate uses, but in the wrong hands, they pose serious risks.

How Irish businesses can respond

As deepfakes become more convincing and accessible, Irish organisations must act proactively. Here are key defence strategies:

Leverage threat intelligence

Understanding the threat landscape is the first step:

Monitor the dark web and illicit marketplaces for signs of executive impersonation or biometric data leakage.
Use behavioural analytics to flag abnormal communication patterns or interactions.
Keep track of industry trends to identify how threat actors are evolving their tactics.

Implement digital risk protection

Executive identity monitoring: Scan for unauthorised content impersonating business leaders.
Fraud detection: Deploy AI tools that can analyse speech patterns and video content to detect anomalies.
Brand protection: Monitor for fake domains, logo misuse, and manipulated media that could damage your organisation’s credibility.

Educate and train employees

Run training sessions to help staff recognise signs of deepfakes, including subtle inconsistencies in video or voice.
Promote the use of multi-channel verification when processing unusual or high-risk requests.
Test staff through simulated deepfake scenarios, not just traditional phishing exercises.

Strengthen authentication and approval processes

Enforce multi-factor authentication (MFA) and implement biometric liveness detection.
Restrict sensitive operations to trusted devices or secure environments.
Apply zero trust principles with least-privilege access to critical systems.

Make your internal processes deepfake-resilient

Reassess critical workflows—particularly those involving money transfers or sensitive data. Ensure no process relies solely on a digital interaction from a known contact. Combine biometric verification with non-biometric checks, and establish clear escalation procedures.

The rise of deepfake social engineering marks a new frontier in cyber threats. For businesses in the Republic of Ireland, this means adapting quickly and decisively. By combining robust technology, intelligent monitoring, clear processes, and informed employees, organisations can build strong defences against this fast-moving threat.

Cyber attackers are getting smarter. It’s time Irish businesses do the same.
