What Do In First 60 Minutes Of New Cyberattack
What Do In First 60 Minutes Of New Cyberattack INTRODUCTION Every organization, no matter the size or sector, faces potential cyber threats daily. When an attack happens, what do in first 60 minutes of a new cyberattack is crucial your actions in this narrow window can determine the extent of damage, data loss, downtime, and financial impact. This detailed blog will walk you through step by step what you have to do in the first 60 minutes of a cyber incident to contain it, protect your assets, and start recovery. Planning for and being familiar with this response not only protects your business but also helps ensure compliance with legal and regulatory obligations. Why The First 60 Minutes Matter The initial 60 minutes after detecting a cyberattack is sometimes called the “golden hour” of incident response. The attackers take this time frame to stage access privileges, lateral movement in your network, exfiltrate sensitive information, or distribute ransomware payloads. Being aware of what to do during first 60 minutes of a new cyberattack helps you: Limit Damage: Spiking the attack from propagating. Maintain Evidence: Critical to forensic investigation and courtroom cases. Minimize Downtime: Rapid response equates to minimal business interruption. Build Customer Trust: Demonstrating control makes stakeholders and customers confident. Comply with Laws: Many laws mandate reporting and response within timely breach. Early Warning Signs of a Cyberattack: Detection You must detect a cyberattack quickly before you can react. Warning signs to be aware of are: Abnormal Network Patterns: Bursts of strange activity or untypical connections with unknown IPs. System Anomalies: Constant rebooting, crashing, or new files. Authentication Failures: Continuing unsuccessful logins or logins during non-work hours. Security Tool Notifications: Firewalls, antivirus, or intrusion detection system alarms. Continuously monitoring security tools like SIEM (Security Information and Event Management) and EDR (Endpoint Detection and Response) solutions are essential to detecting early. Step 1: Validate the Incident (First 5-10 Minutes) As soon as an alert or suspicion is raised, your first action in what to do in first 60 minutes is to determine if an actual attack is occurring: Validate alerts by correlating system and security logs. Identify what systems or data has been attacked. Determine whether the anomaly is due to a cyberattack or false positive/system error. Avoid making hasty actions without confirmation, as unjustified interruptions can impact business procedures. Step 2: Isolate Compromised Systems (10-20 Minutes) Isolate compromised systems immediately once confirmed to contain the threat in its place: Disable or reset stolen access credentials or user accounts. Network segmentation and strict access controls reinforce this action. Remember, isolation does not mean shutting down everything—it means stopping the spread with evidence intact. Step 3: Alert Your Incident Response Team (15-30 Minutes) Cyberattack response is a team effort. Security analysts IT administrators Legal and compliance officers Communication and PR team Your IRT should know the incident response plan so you can respond well and minimize confusion throughout the crisis. Step 4: Preserve Key Evidence (20-40 Minutes) Preserving evidence is perhaps the most important, and most often omitted, step of what to do in first 60 minutes. Good evidence allows you to: Analyze how the attacker broke in. Identify vulnerabilities that were exploited. Support law enforcement and legal cases. Steps to preserve evidence are: Capturing system and network logs, alerts, and screenshots. Prevention of powering off or restarting infected devices, except in extreme cases. Logging all actions taken as a response. Step 5: Communicate Transparently (30-50 Minutes) Communication in the event of a cyberattack is unavoidable. Good communication involves: Notification of internal stakeholders (management, employees). Alerting affected customers or partners in case of personal data compromise. Drafting messages to regulatory authorities to meet breach notification laws (GDPR, HIPAA, etc.). Transparent and prompt communication assists in the preservation of trust and minimizes reputational loss. Step 6: Start Recovery Planning (50-60 Minutes) After containment and communication, plan the recovery process: Discover vulnerabilities to patch in minutes. Prepare for restoring systems from clean backups. Establish ramped-up monitoring for lingering threats. Recovery planning enables your organization to return to regular operations securely and quickly. Critical Rapid Response Tools In order to properly execute what do in first 60 minutes, you need the right technology stack: SIEM Systems: Correlate and process security logs in real-time. EDR Tools: Detect and respond to threats on endpoints. Network Segmentation: Limits attacker mobility within your network. Automated Response Platforms: Enable quick, predictable incident response. Backup Solutions: Have the ability to recover data in the case of ransomware or data loss. Overlooking initial warnings or delaying action. Failing to quickly isolate infected systems. Failing to immediately involve key stakeholders. Neglecting the necessity of maintaining evidence. Delayed or poor customer and regulator communications. Preparing for the Inevitable: Developing Your Incident Response Plan Having an idea of what to do in the first 60 minutes of a cyberattack is only effective if you have a plan. Your incident response plan should: Define roles and responsibilities. Establish communication protocols. Outline containment, eradication, and recovery processes. Step 7: Conduct a Rapid Impact Assessment (60-90 Minutes) After the initial containment and recovery planning is completed, it is necessary to conduct a rapid impact assessment so that one can understand the magnitude of the attack. It helps to answer some of the important questions: What was accessed or destroyed? Which business functions are affected and to what extent? Do any regulatory or legal penalties exist? What are the costs incurred thus far? Knowing how to act within first 60 minutes includes assessing damage upfront, enabling recovery prioritization and resource allocation. Step 8: Implement Improved Monitoring and Detection After determining the attack vector and getting it under control, increase monitoring throughout your network to monitor for any lingering threats or attacker backdoors: Raise log verbosity and retention. Utilize threat intelligence feeds to monitor attacker indicators of compromise (IOCs). Such constant monitoring prevents reinfection or a second wave of attacks. Step 9: Involve External Experts and Authorities Depending on severity and type of attack, engage external parties what they do
