What to Do If Your Business Gets Hacked: Immediate Steps for Cyberattack Response

Cyberattacks are a constant threat to businesses of all sizes, with incidents rising 18% year-over-year. They disrupt operations, reduce revenue, damage customer trust, and increase regulatory risk. The speed and effectiveness of your response are critical to minimizing impact.

Signs You've Been Hacked

Detecting a data breach early is crucial to minimizing the damage it can cause.

Warning signs that could indicate your business has been hacked include:

Unusual login activity.
Locked accounts or receiving password reset emails you didn’t initiate.
Strange email messages.
Rogue software installations.
Computers or systems are running slower than usual, freezing, or crashing.

More serious indicators of an incident include unusual network traffic patterns, a surge in requests for the same file, geographical irregularities, and unauthorized database extractions.

While attack methods evolve, human error remains the primary vulnerability. A recent Resilience survey found that 85% of losses are linked to employee mistakes, up from 17% in 2024. Employee education and proactive security measures, including system monitoring and network traffic detection, are essential for cybersecurity.

What Happens When a Company Gets Hacked?

A cybersecurity incident can have a devastating impact on a business, affecting multiple areas of operations.

These include:

Operational disruption

A major consequence of a data breach is unplanned downtime, which can halt operations. Extended downtime increases costs. In some cases, cybercriminals intentionally disrupt operations to demand ransom.

Revenue interruption

A data breach can result in significant financial losses, both immediate expenses for recovery and remediation and long-term costs from lost business opportunities and legal liabilities.

Customer trust

Customer trust is essential in today’s connected environment. Beyond immediate costs, breaches can erode confidence, delay sales, and harm long-term brand reputation. One study found that 64% of customers would trust brands more if they adopted advanced security technologies.

Regulatory reporting

Depending on the industry and location, businesses may be subject to various data protection regulations and compliance requirements. A data breach can result in non-compliance penalties and regulatory fines.

Immediate Action Steps for Operational Leaders

No organization can fully eliminate cyber risk. The key difference between a manageable incident and a crisis is how quickly the threat is contained and how well leaders coordinate the response.

1. Know Who Owns the Response

Effective planning ensures a clear response when incidents occur. However, many organizations discover during a crisis that responsibility for coordination is unclear.

An IBM report found that incident response planning and testing can reduce average data breach costs by $1.5 million. An incident response team serves as your first line of defense during a security breach.

Include roles from:

Executive leadership
IT/Security
Legal
HR
Communication/Marketing
External cybersecurity professionals
Insurance providers

2. Assess the Impact

Determine the nature of the attack, including:

Identifying the type of cyberattack (e.g., ransomware, phishing).
Ascertaining which data and systems were affected.
Evaluating the potential impact on operations and stakeholders.

Next, create a comprehensive recovery plan to restore systems, data, and operations. Address all identified vulnerabilities to prevent future breaches.

3. Notify Relevant Parties

Compliance with legal and regulatory requirements is non-negotiable. This may include:

Reporting the incident to appropriate authorities, like the FBI's Internet Crime Complaint Center (IC3).
Informing affected customers, partners, and employees as necessary.
Consulting legal counsel to navigate disclosure obligations.

4. Begin Recovery and Remediation

Work towards restoring normal operations, including:

Removing malware and secure vulnerabilities.
Restoring data from clean backups.
Monitoring systems for any signs of lingering threats.
Review cyber insurance requirements, including notification deadlines, required forensic investigations, coverage limitations, and documentation expectations.

After these steps, continue to monitor gaps, track timelines, and communicate with affected parties.

How Quickly Can You Continue Operating?

Cyberattacks and other threats are inevitable. The level of your preparedness will determine how quickly you can resume operations.

To begin, ask yourself the following questions:

What systems are essential to revenue-generating operations?
Which vendors need notification?
What customer-facing services must be restored?
Can you resolve corrupted data?
How long will it take to restore critical workflows?

Your answers to these questions will clarify your organization’s readiness to restore operations.

After an incident, take proactive steps to strengthen your organization's defenses:

Review and Update Security Policies: Ensure protocols are up-to-date and comprehensive.
Conduct Employee Training: Educate staff on how to recognize and respond to cyber threats.
Implement Advanced Security Tools: Utilize intrusion detection systems and endpoint protection.
Regularly Test Incident Response Plans: Conduct drills to assess readiness and identify areas for improvement.

Emerging Cyber Risks Leaders Should Watch

Cyber threats continue to evolve as attackers adopt new technologies, techniques, and targets.

AI-enabled Attacks

CrowdStrike reports an 89% increase in attacks by AI-enabled adversaries. As AI agents become more common, technology and security leaders need a targeted, risk-based approach that focuses on the greatest gaps and uses automation and integration where they can strengthen protection. This helps organizations support innovation, maintain compliance, and protect critical assets in AI-driven environments.

Deepfake impersonation attempts

Cyber criminals are using highly convincing identity fabrications. In a professional setting, this applies to business email compromise, where counterfeit voices and audio can mimic professionals and exploit vulnerabilities. The ITRC’s mid-2026 report cited over 1,800 data compromises in the first quarter of 2026 alone.

IoT and other connected devices

The growth of interconnected devices creates new entry points for attackers. A Fortinet study found that half of operational technology organizations experienced cyber breaches. Industries such as manufacturing are especially vulnerable due to numerous interconnected and exposed networks. It is essential to secure both networks and every embedded device.

Supply chain and vendor vulnerability

Even with strong internal defenses, reviewing your vendors’ security practices is essential. Attackers often target third-party vendors or open-source software. According to IBM, major supply chain and third-party breaches have quadrupled, largely due to the complexity of modern software dependencies and cloud-based services.

Build Long-Term Cyber Resilience

Cybersecurity extends beyond IT departments. Leading organizations integrate cybersecurity into their core values, promoting a proactive approach to emerging threats.

Executive Leadership: Drive cybersecurity initiatives from the top to ensure alignment with business objectives.
Employee Engagement: Promote awareness and responsibility across all levels of the organization.
Continuous Improvement: Regularly assess and update security protocols to adapt to evolving threats.

Organizations that recover most effectively from cyberattacks are those that prepare in advance. Combining strong cybersecurity practices, tested response plans, and operational resilience strategies reduces disruption and supports confident recovery.
