Ransomware Protection: Prevention, Detection, and Recovery Strategies

The Ransomware Epidemic

Ransomware attacks have grown into a multi-billion dollar criminal industry. Attackers encrypt your files and demand payment - often in cryptocurrency - for the decryption key. The average ransom demand exceeded $250,000 in 2025, and many organizations pay because they have no viable alternative. Prevention is always cheaper than remediation.

Prevention Starts With Backups

The most effective ransomware defense is a robust backup strategy. Follow the 3-2-1 rule: maintain three copies of your data, on two different media types, with one copy stored offsite or in the cloud. Critically, at least one backup must be immutable or air-gapped so that ransomware cannot encrypt it along with your live data. Test your restoration process quarterly to verify that backups actually work.

Detect Ransomware Early

Ransomware typically has a dwell time of hours to days before it begins encrypting. During this period, attackers perform reconnaissance, escalate privileges, and disable security tools. Watch for early warning signs: disabled antivirus services, unusual PowerShell activity, mass file renaming operations, and lateral movement between machines. True Protection monitors for these precursor activities and can halt an attack before encryption begins.

Response and Recovery

If ransomware does activate, isolate the affected machines from the network immediately by disconnecting cables and disabling Wi-Fi. Do not power off the machines, as memory may contain decryption keys. Document everything for law enforcement. Begin restoring from your most recent clean backup. Never pay the ransom unless it is your absolute last resort - payment funds further attacks and there is no guarantee you will receive a working decryption key.

Building Resilience

Conduct ransomware tabletop exercises with your team at least annually. Everyone should know their role during an incident. Maintain an offline copy of your incident response plan, contact lists, and critical passwords. When minutes count, you cannot afford to search for instructions on an encrypted computer.
