What should a venue do after a malware incident?

Contain it first, recover second, and then rebuild to a standard rather than back to what you had. Restoring the arrangement that was compromised restores the exposure that allowed it, which is the most common and most understandable mistake made in the fortnight after an incident.

Containment in the first hour means disconnecting affected machines from the network without powering them off, stopping use of connected systems, and calling for help immediately. Powering off can destroy evidence that helps establish what happened; disconnecting stops the spread. In a venue that also means deciding quickly how to keep trading, which is where the manual fallback process earns its existence.

Recovery depends almost entirely on a decision made months earlier: whether your backups have been restored and tested. A venue with proven restores is dealing with days of disruption. One that discovers its backups were failing quietly is rebuilding from nothing, with bookings, sales history and configuration all gone. That difference is not determined during the incident.

Then the part that matters most and is easiest to skip under pressure to reopen. Rebuild to a standard rather than to the previous configuration: segmented networks, guest Wi-Fi genuinely separated, multi-factor authentication everywhere, managed devices, tested backups. Karidis Corporation did exactly that after a malware incident in 2023, rebuilding to 100% Essential Eight compliance with 99.99% uptime and 600 Mbps guest Wi-Fi. That is what a recovery looks like when it is used properly. If you want help rebuilding to a standard, call 1800 456 567.
