Contain the attack before trying to fix anything. Activate your incident-response plan, isolate affected systems in a coordinated way, and switch to phone or another out-of-band channel. Do not routinely shut computers down: powering off can erase volatile evidence. Preserve what you can, bring in qualified responders, report through established channels, and recover only from clean, offline backups.
The sequence below follows the joint CISA, FBI, NSA and MS-ISAC #StopRansomware Guide identified as the September 2023 guide (the CISA publication listing gives a revision date of October 19, 2023). Guidance and contact routes can change, so verify that a newer edition and current reporting channels are not available when an incident occurs.

The first response sequence
Ransomware response is not a single decision such as “pay or do not pay.” It is a controlled sequence designed to stop spread, protect evidence, understand scope, and restore operations without reinfecting clean systems. The federal guide expressly says to move through its first three steps in sequence.

- Activate the incident-response plan and coordinate containment. Identify apparently affected systems and isolate them promptly.
- Preserve evidence while triaging. Prioritize critical systems, document observations, and capture information before it disappears.
- Notify the right people and request help. Coordinate internally and use established government, insurance, legal and technical channels.
- Recover on a clean basis. Rebuild or restore in a controlled environment from protected backups, then reconnect deliberately.
- Assess data exposure and obligations. Preserve facts about possible access or exfiltration and follow the applicable response and legal plans.
These actions overlap operationally, but containment comes first. A rushed restoration or an uncoordinated shutdown can spread the intrusion or destroy information investigators need.

1. Activate the incident-response plan and establish command
Use the organization’s incident-response plan immediately, even if the evidence is still incomplete. Name an incident lead, define who can authorize isolation and recovery, and bring in internal IT or security staff. Involve management, a managed security provider, cyber-insurance contacts, legal counsel and communications staff when those functions are part of your plan.
Confirm what is known without delaying containment
- Record the first observed ransom note, encryption message, unusual login, outage or other indicator, including date and time.
- List systems that are unavailable, showing ransom notes, behaving unusually or reporting encrypted files.
- Mark business-critical services and the data they hold, such as identity systems, financial applications, production systems and customer records.
- Assign one person to maintain an incident log. Write down actions, decisions, people involved and exact times.
Do not wait for a perfect inventory before isolating a clearly affected machine. The objective is to limit lateral movement while responders establish the broader scope.
2. Isolate affected systems in a coordinated manner
Containment is the first operational priority. The guide recommends coordinated isolation rather than disconnected, improvised actions that could alert attackers on one system while leaving others exposed. If several systems or subnets appear compromised, taking the relevant network offline at the switch level may be necessary.

| Situation | Preferred containment action | Important trade-off |
|---|---|---|
| A single device appears affected and the network team can reach it | Disconnect that device from Ethernet and Wi-Fi, following the response plan. | Keep it powered for evidence unless another risk requires shutdown. |
| Several devices in one segment show signs of compromise | Coordinate isolation of the segment, potentially taking it offline at the switch level. | Business services on that segment may stop; document what was disconnected. |
| Multiple subnets or the wider environment may be compromised | Use network-level containment directed by qualified responders. | A broad outage may be safer than allowing continued lateral movement. |
| A device cannot be disconnected by network controls or physical cable/Wi-Fi removal | Consider powering it down as a fallback. | Shutdown can destroy volatile memory and other evidence. |
Do not reconnect a device merely to test whether it still works. Reconnection can give an attacker a path back into systems that have not been examined.

Use out-of-band communications
Assume compromised systems and ordinary organizational channels may be monitored. The guide recommends phone calls or other out-of-band methods so attackers are less likely to learn that mitigation is underway. Use a known-clean phone, personal contact method approved by the organization, or another channel outside the potentially compromised environment. Keep sensitive incident details out of email, chat and shared drives until responders establish that those systems are trustworthy.
3. Should you turn off the computer?
Only when you cannot isolate it from the network by another means, or when responders direct you to do so. Powering down can limit spread when a machine cannot be disconnected, but shutdown may destroy evidence held in volatile memory. That memory can contain running processes, attacker tools, encryption keys, network connections or other clues that disappear when power is removed.
A practical decision rule
- Attempt network isolation first: disable the relevant switch port, remove the Ethernet cable or disable Wi-Fi according to the plan.
- If the device remains able to communicate and no other isolation method is available, consult the incident lead or responder about shutdown.
- Before shutdown, record the device name, logged-in user, screen messages, visible ransom note and time. Photograph the screen if policy permits and doing so will not expose sensitive information.
- After shutdown, label the device and do not restart it until qualified responders decide how to examine it.
This rule balances containment against forensic value. It is not a guarantee that every machine should remain powered: an actively spreading system may present a greater immediate risk than the evidence it contains.
4. Triage, document and preserve evidence
Once immediate isolation is underway, determine which systems and data matter most. Prioritize systems that support safety, essential operations, identity and access, communications, financial processing and other critical functions. Establish what data each system stores and whether it may contain personal, regulated or contractually protected information.

Preserve volatile and short-retention information
If immediate mitigation is not possible, the CISA checklist recommends taking a system image and memory capture from a sample of affected devices. It also calls for relevant logs and malware samples, plus volatile evidence such as system memory and short-retention security or firewall logs. Do not attempt unfamiliar forensic procedures on every endpoint; a well-intentioned script, reboot or cleanup utility can overwrite useful evidence.
- Engage qualified incident responders or digital-forensics specialists when the organization lacks this capability.
- Preserve the original ransom note, suspicious files, email messages, authentication records and alerts in a controlled location.
- Export logs before their retention period expires, including identity, endpoint, firewall, VPN and cloud-service records that are relevant to the suspected window.
- Keep a chain-of-custody record for collected devices, images, memory captures and malware samples.
- Record time zones and clock differences so investigators can reconstruct events accurately.
Evidence preservation is not separate from business triage. A short-retention firewall log may help determine whether data left the network; a system image may show how the attacker entered and whether a backup environment was touched.
5. Notify internal stakeholders and request assistance
Follow the organization’s communications plan rather than sending an improvised company-wide message. Management needs a factual status and decision points; IT and security need authority and resources; legal and communications teams need verified information; insurers may require specific notice or use of approved responders.

Early reporting can support coordination and investigation. It does not replace internal containment, legal analysis or insurance notice. Preserve the incident log and the facts shared with each outside party.
6. Assess possible data access or exfiltration
Encryption alone does not establish whether information was stolen, and the absence of an obvious theft notice does not prove that it was not. Preserve facts that can answer who accessed which systems, when, and whether data moved outside the environment. Review identity, endpoint, firewall, VPN, cloud and other relevant logs with qualified responders.
If personal or business data may have been accessed or exfiltrated, activate the organization’s breach-response and communications plans. Notification duties depend on the affected data, people, contracts, industry rules and jurisdictions involved. The cited federal checklist directs organizations to follow those plans; it does not provide one universal deadline or notification rule for every business. Obtain jurisdiction-specific legal advice before notifying customers, regulators, employees or contractual partners.

Recovery begins after responders have assessed scope and identified restoration priorities. Do not reconnect a backup server or unaffected workstation simply because it appears normal. Attackers may have reached systems that were not yet showing encryption, and accessible backups may have been encrypted or deleted.

Build a clean recovery path
- Identify systems required for safe, essential operations and rank them for restoration.
- Establish a controlled recovery environment separated from suspected compromised infrastructure.
- Validate that operating systems, applications, identities and security controls are rebuilt or verified from trustworthy sources.
- Restore from offline, encrypted backups whose availability and integrity have been checked.
- Change credentials and review privileged access before reconnecting restored systems.
- Monitor restored systems for indicators of reinfection and reconnect in stages.
Keep restoration records: backup set used, validation performed, system owner, connection time and monitoring results. If a restored host shows suspicious activity, isolate it again rather than allowing the problem to spread through the recovery environment.
Ransom payment is not a recovery plan
The cited checklist does not establish a universal ransom-payment rule. Do not present payment as routine, guaranteed or sufficient to recover operations. A payment may not produce a working decryptor, may not address stolen data, and does not remove the attacker’s access. Consult law enforcement, legal counsel, insurers and qualified responders before making any decision, and consider applicable sanctions and other legal constraints.
Common first-response mistakes
- Shutting every machine down immediately: this can erase volatile evidence and may leave responders with less information about the intrusion.
- Letting each employee act independently: uncoordinated isolation can miss connected systems or alert attackers through monitored channels.
- Continuing to use compromised email or chat: attackers may observe plans and credentials in those systems.
- Deleting ransom notes or reformatting drives: cleanup can remove indicators investigators need.
- Testing backups by reconnecting them to production: an attacker can reinfect the backup or restored environment.
- Restoring before understanding scope: an undiscovered foothold can compromise clean systems again.
- Assuming encryption proves the whole incident: access and exfiltration require separate investigation.
- Waiting to report until after recovery: assistance, evidence and reporting decisions are most useful early.
A concise first-day checklist
- Activate the incident-response plan and appoint an incident lead.
- Move coordination to out-of-band communications.
- Isolate affected devices, segments or switches in a coordinated manner.
- Use shutdown only when network isolation is not possible and the risk justifies losing volatile evidence.
- Record systems, users, symptoms, times and actions in an incident log.
- Protect memory, images, logs and malware samples with qualified assistance.
- Notify management, IT/security, insurers, legal and communications teams as required by the plan.
- Report to appropriate U.S. agencies or law enforcement when advised.
- Determine critical systems, likely data exposure and restoration priorities.
- Restore in a segregated environment from offline, encrypted backups and reconnect in controlled stages.
Prepare before the next incident
The incident exposes whether the response plan works in practice. Update contact lists and out-of-band methods, define who can authorize network isolation, and rehearse the decision to disconnect versus shut down. Maintain offline, encrypted backups of critical data and test both their availability and integrity regularly. Backups that remain continuously accessible can be found, encrypted or deleted by ransomware.
