Ransomware Recovery: What Happens After You Get Hit and How to Prepare

Ransomware has become the dominant cyberthreat facing Canadian businesses. Attackers encrypt your files, demand payment, and often threaten to publish your data if you refuse. The businesses that recover fastest aren't the ones that pay — they're the ones that planned ahead.

What Actually Happens During a Ransomware Attack

Most organizations discover ransomware when users start seeing encrypted files or ransom notes appear on their screens. By that point, the attacker has often been inside the network for days or weeks — conducting reconnaissance, disabling backup tools, and ensuring the maximum number of systems are affected before triggering the encryption.

This is why having backups isn't enough. How those backups are configured determines whether they survive.

What Good Recovery Preparation Looks Like

Immutable, air-gapped backups. Backups that are connected to the network can be encrypted along with everything else. Backups need to be stored in a way that ransomware cannot modify or delete them — either through immutability settings in cloud storage or physical air-gapping from the network.

Tested recovery procedures. Most organizations have never actually run through a full system restore. When a crisis hits is the wrong time to discover your backups are incomplete or your team doesn't know the recovery process. Recovery testing should be scheduled and documented.

An incident response plan. Who do you call when it happens? Who makes the decisions? Who communicates with customers and regulators? Who contacts your cyber insurer? These decisions are too important to make up under pressure.

Segmented networks. If your entire network is flat, ransomware spreads laterally without friction. Network segmentation limits the blast radius of an infection — keeping a compromise in one area from taking down everything.

Should You Pay the Ransom?

Law enforcement agencies and cybersecurity organizations generally recommend against payment. Paying doesn't guarantee recovery, funds criminal organizations, and marks you as a willing payer — making you a likely target again. That said, for organizations without adequate backups, payment can feel like the only path to recovery. This is exactly why preparation matters before an incident occurs.

The Cost of Not Preparing

The average downtime from a ransomware attack is measured in weeks, not days. Factor in lost productivity, emergency recovery costs, regulatory notifications, potential regulatory fines, and reputational damage — and the cost of preparation looks very different compared to the cost of recovery.

A tested backup and recovery plan, a documented incident response process, and basic network segmentation are investments that pay for themselves many times over when the alternative is a multi-week outage.
