Ransomware Attack What To Do in Smyrna, GA

Ransomware Attack: What to Do If Your Smyrna Business Is Hit

Ransomware does not announce itself with a warning. One morning your staff cannot open files, your DMS is frozen, or a ransom note appears on every screen. If your Smyrna or Cobb County business is in that moment right now, the next 30 minutes matter more than the next 30 days of cleanup. COMNEXIA has responded to ransomware incidents for Georgia businesses since 1991, and this page gives you the exact sequence of steps to take, plus what proper pre-incident controls look like so you are never reading this guide under duress.

Immediate Steps: The First 30 Minutes

Speed and precision reduce the blast radius. Work through this list in order:

• Isolate, do not power off. Disconnect affected machines from the network by unplugging ethernet and disabling Wi-Fi adapters. Powering off can destroy forensic artifacts in memory that are needed to identify the ransomware strain and entry point.
• Disable shared drives and cloud sync. Disconnect mapped network drives and pause OneDrive or SharePoint sync on any machine still online. Ransomware traverses SMB shares and can encrypt cloud-connected folders within minutes.
• Preserve your logs before they are overwritten. Ask your IT team or MSP to export Windows Event Logs, firewall logs, and any EDR telemetry immediately. SentinelOne EDR retains process-level telemetry and can replay the attack timeline; if your environment has SentinelOne deployed, do not roll back the agent before that data is captured.
• Contact your incident response partner. Call COMNEXIA at (877) 600-6550. Do not attempt to negotiate with attackers, click ransom-payment links, or restore from backup until the infection vector is confirmed closed, or you risk re-infection within hours.
• Document everything with timestamps. Photograph ransom notes, note which systems are affected, and record the exact time staff first noticed the problem. This documentation supports insurance claims, regulatory notifications, and law enforcement if you choose to report to the FBI IC3.
• Notify leadership and legal counsel. If your business stores payment card data, protected health information, or customer financial records, a breach notification clock may already be running under PCI DSS, HIPAA, or the FTC Safeguards Rule (16 CFR 314.4).

The Dealership Scenario: CDK, Reynolds and Reynolds, and the FTC Safeguards Rule

Smyrna is minutes from the auto-dealer corridor on Cobb Parkway. If your dealership runs CDK Global, Reynolds and Reynolds, or Dealertrack as your dealer management system, ransomware that locks your DMS stops every finance deal, service write-up, and parts transaction simultaneously. The FTC Safeguards Rule (16 CFR 314.4) requires auto dealerships that are financial institutions to maintain an incident response plan, designate a qualified individual, and notify the FTC within 30 days of discovering a breach affecting 500 or more customers. A ransomware event that touches customer financial records almost certainly triggers that notification requirement. COMNEXIA works with Smyrna-area dealerships to document incident response plans that satisfy Safeguards Rule Section 314.4(h) before an attack occurs, not after.

What Containment and Recovery Actually Look Like

After isolation, COMNEXIA's recovery process follows a defined sequence. First, the team identifies the ransomware strain using SentinelOne threat intelligence or Microsoft Defender for Endpoint's incident graph, which maps the lateral movement path and the initial access vector (most commonly a phishing email, exposed RDP port, or unpatched VPN appliance). Second, the compromised accounts are disabled in Microsoft Entra ID and all active sessions are revoked using the "Revoke Sign-In Sessions" control, cutting off any attacker maintaining persistence through a stolen token. Third, we validate that your immutable backups are clean. COMNEXIA configures off-site backups following the 3-2-1 model: three copies of data, two different media types, one copy stored off-site and air-gapped so ransomware cannot reach it. Recovery point objectives depend on your backup schedule, which is why backup frequency is set before an incident, not improvised during one.

Controls That Prevent the Next Attack

Paying a ransom or restoring from backup without closing the entry point is a guarantee of re-infection. After containment, COMNEXIA hardens the environment using these specific controls:

• Microsoft Entra ID conditional access policies that block authentication from non-compliant devices and require phishing-resistant MFA (FIDO2 or Microsoft Authenticator number matching) for all privileged accounts.
• SentinelOne EDR deployed to every endpoint with autonomous response enabled, so lateral movement is stopped at the process level even if a human analyst is not watching in real time.
• NinjaOne RMM used to enforce patch management across all Windows and third-party applications on a documented cycle, closing the unpatched-VPN and unpatched-OS vulnerabilities that ransomware actors exploit most frequently.
• Phishing-simulation security awareness training delivered on a monthly cadence, because the majority of ransomware chains begin with a user clicking a credential-harvesting link.
• 24/7 SOC monitoring through Microsoft Defender for Cloud, providing continuous alerting on anomalous login behavior, privilege escalation, and mass file-encryption activity.
