Ransomware Recovery: What to Do When Your Miami Business Is Attacked

Despite your best preventive efforts, ransomware may still hit your Miami business — it's one of the most pervasive threats facing South Florida organizations today. Having a clear recovery plan before an attack occurs means the difference between restoring operations in hours versus days, and potentially avoiding the ransom payment entirely. This guide covers what to do in the immediate aftermath of a ransomware attack.

Immediate Response: First 30 Minutes

The moment you discover ransomware, act fast: disconnect affected devices from the network immediately (unplug network cables or disable Wi-Fi) to prevent the ransomware from spreading to other systems and network shares; do not turn devices off — powered-on devices may contain encryption keys in memory that forensic investigators can extract; contact your IT support immediately (call Infinity Network Support at 786-991-0111 for Miami clients); preserve evidence by photographing ransom notes and documenting what you know about the initial infection; and notify your cyber liability insurance carrier as soon as possible.

Assess the Scope

Before beginning recovery, understand what was encrypted: which servers, workstations, and network shares were affected; whether backups were encrypted or deleted (the first thing sophisticated ransomware attacks do is target and destroy backup systems); the strain of ransomware (some have known decryptors available from law enforcement that may allow decryption without paying the ransom); and whether data was exfiltrated before encryption (a common tactic in double-extortion attacks that creates additional notification obligations).

Restore from Backup

If your backups are intact and tested, recovery without paying is achievable. The recovery sequence: rebuild clean server infrastructure (bare metal or VM) rather than restoring the OS of encrypted machines; restore critical data from the most recent clean backup point (before infection, which may require going back days or weeks if the infection was dormant); verify restored data integrity before reconnecting to the network; and investigate and remediate the initial attack vector before restoring connectivity to prevent immediate reinfection.

Post-Incident: Preventing Recurrence

After recovering from ransomware, conduct a thorough root cause analysis to understand how attackers gained initial access. Address the vulnerability immediately. Implement additional controls that would have prevented or limited the attack. Update your incident response plan with lessons learned. And verify your backup strategy meets 3-2-1-1-0 standards so the next attack (and there will be another attempt) doesn't succeed.
