Email Hacked in Chamblee, GA

Email Hacked Business in Chamblee, GA: Incident Response and Long-Term Protection from COMNEXIA

When a Chamblee business discovers its email has been compromised, the first 60 minutes determine how much damage is contained. Attackers who gain access to a Microsoft 365 or Google Workspace account immediately search for wire-transfer threads, vendor payment details, and saved credentials. They set forwarding rules to a hidden external address so they keep reading your mail even after you reset a password. COMNEXIA, headquartered in Roswell, GA and serving DeKalb County businesses since 1991, responds to active email compromises and then hardens the environment so the same attack cannot succeed twice.

What "Email Hacked" Actually Means for a Chamblee Business

Business email compromise (BEC) is not simply a stolen password. A typical incident unfolds in three layers. First, an attacker authenticates through a phished credential or a password-spray attack against an account with no multi-factor authentication. Second, they create inbox rules that delete or redirect replies, making the compromise invisible for days or weeks. Third, they impersonate the account to redirect an ACH payment or to request a gift-card purchase from an employee. For auto dealerships in the Chamblee corridor that process daily floor-plan draws through CDK Global, Reynolds and Reynolds, or Dealertrack portals, a single fraudulent wire can exceed a vehicle's invoice cost. The FTC Safeguards Rule (revised June 2023) now requires dealers to maintain an incident-response plan covering exactly this scenario, including written documentation of how unauthorized access to customer financial data is detected and reported.

COMNEXIA's Immediate Response Steps

• Revoke all active Microsoft 365 or Google Workspace sessions for the compromised account using the admin console "Sign out everywhere" function and invalidating refresh tokens through Microsoft Entra ID (formerly Azure AD).
• Audit and delete malicious inbox rules. In Exchange Online this is done through the Exchange Admin Center and confirmed with PowerShell's Get-InboxRule cmdlet to catch rules the GUI may not surface.
• Review the Microsoft 365 Unified Audit Log or Google Workspace Admin audit log for mail-forwarding configuration, OAuth app grants, and any new delegate access added during the compromise window.
• Block the attacker's confirmed IP addresses or geographic regions in Microsoft Entra ID Conditional Access while the full scope is assessed.
• Preserve log evidence before it ages out. Microsoft 365 audit logs default to 90-day retention on many licensing tiers; COMNEXIA exports and archives relevant records for any potential insurance or law-enforcement filing.
• Notify affected parties. If customer financial records were accessed, Georgia's personal data breach notification law (O.C.G.A. Section 10-1-912) requires prompt written notice to affected Georgia residents.

Hardening the Environment After a Compromise

Resetting the breached password is not a remediation; it is a starting point. COMNEXIA configures Microsoft Entra ID Conditional Access policies that require phishing-resistant MFA (Microsoft Authenticator with number matching, or FIDO2 hardware keys) for every sign-in, and that block authentication from countries where your business has no legitimate users. For dealerships running Dealertrack or CDK, COMNEXIA maps which staff roles require portal access and restricts Conditional Access named locations to approved IP ranges, reducing the attack surface those logins present.

On the endpoint side, SentinelOne EDR is deployed to detect credential-harvesting malware that may have been the original source of the stolen password. Patch management through NinjaOne ensures that browser and email-client vulnerabilities used in phishing kit delivery are closed within the patch cycle, with compliance reported monthly so management can see where gaps existed before the incident and confirm they are closed. Microsoft Defender for Office 365 (Plan 1 or Plan 2 depending on licensing) is configured with Safe Links and Safe Attachments policies active, with the "Dynamic Delivery" option enabled so attachments are scanned without blocking mail flow.

Why Chamblee Businesses Call COMNEXIA

Chamblee's Buford Highway corridor and the Peachtree Road business district include a dense mix of import-auto dealers, professional service firms, and multi-location retail operators, all of whom process vendor payments and customer financial data through email. These businesses often lack an internal IT team that can simultaneously contain an active incident, preserve forensic logs, and communicate with a cyber-insurance carrier. COMNEXIA's help desk operates with a formal ticketing system so that every action taken during an incident is time-stamped and documented, which insurance adjusters and FTC Safeguards Rule auditors require. Onboarding into COMNEXIA's managed services program includes an endpoint standardization audit that identifies accounts lacking MFA before an attacker finds them first.
