Ransomware recovery: what to do in the first 24 hours
Speed and discipline matter. A tested response plan is the difference between hours and weeks of downtime.
A successful ransomware attack is not the end — if you are prepared. Resilient organizations recover because they rehearsed the scenario before it happened.
The first hours
- Isolate affected systems to stop the spread
- Activate your incident response plan
- Identify the last clean backup copy
- Notify relevant parties (including per NIS2)
Why immutable backup is decisive
If your backups can be encrypted by the attacker, you have nothing to recover from. Immutable and air-gapped copies guarantee a clean point of return.
Preparation beats improvisation
Root Security helps organizations build and test their ransomware preparedness, so recovery is a procedure, not a panic.
