Ransomware readiness checklist for small business

Test backups and define isolation, communication, and escalation before pressure arrives. This guide starts with actions that are low-risk, reversible where possible, and useful even when the exact cause is still uncertain. If there is an immediate financial, workplace, safety, or legal concern, use the responsible provider or local authority’s current process.

First ten minutes

1. 01
   Pause before deleting or resetting

   A rushed clean-up can remove the detail that makes recovery easier.

2. 02
   Record the time, what changed, and the account or device involved

   A short note is often more useful than a perfect reconstruction later.

3. 03
   Use a trusted route to the relevant provider or team owner

   Open saved bookmarks, device settings, or official support pages rather than links from an alert.

What to preserve

Keep the message, notice, filename, time, affected address or device name, and screenshots of unusual settings if doing so is safe. Do not send passwords, recovery codes, private keys, or unredacted identity documents to an unverified contact. A record supports a provider or team that needs to understand what happened.

Escalate when

Escalate when access cannot be recovered through an official route, a payment method or sensitive data may be involved, the event affects a workplace, or you are being pressured to act quickly. The appropriate destination might be an account provider, bank, employer, insurer, qualified incident responder, or public reporting route in your jurisdiction.

Recovery path

After containment, review recovery options, active sessions, forwarding rules, software updates, backups, and credentials reused elsewhere. Make one change at a time when you can, then write down what was changed. That record helps you avoid repeating work and gives a small team a usable handover.
