The Challenge
In October 2024, CybrogenIT was contacted by an electrical contracting company with 22 employees after noticing unauthorized activity in their QuickBooks account and missing invoices. The company relied on cloud-based tools for project management, scheduling, and billing, making digital access critical to its daily operations.
A cybersecurity scan revealed seven compromised accounts, three infected devices, and nine findings on the dark web related to company logins. Attackers had gained access through a phishing email that appeared to come from a general contractor requesting a quote. Once inside, they stole credentials, accessed the company’s accounting platform, and attempted to reroute payments from two active commercial projects.
Further analysis revealed five open ports, three unpatched vulnerabilities, and missing SPF and DKIM records, which enabled attackers to spoof company emails. Without immediate intervention, the business faced financial loss, reputational damage, and potential contract disputes due to falsified invoices.
What We Did
CybrogenIT deployed a rapid containment and remediation plan to stop the fraud, secure systems, and strengthen the company’s cybersecurity posture.
Incident Response & Containment
Isolated compromised accounts and reimaged infected devices.
Terminated unauthorized QuickBooks sessions and reset administrator credentials.
Blocked suspicious IP addresses and malicious domains associated with the phishing campaign.
Financial Recovery & Verification
Coordinated with the accounting platform and banks to reverse attempted fraudulent transfers.
Verified the integrity of all financial data and restored missing invoices from secure backups.
Implemented transaction monitoring alerts to detect future anomalies.
Network & Email Security
Closed open ports and patched all unaddressed vulnerabilities.
Configured SPF, DKIM, and DMARC to prevent email spoofing.
Deployed AI-based phishing filters and sandboxing for all inbound attachments.
Identity & Credential Protection
Enforced multi-factor authentication (MFA) across all business systems.
Integrated dark web monitoring for ongoing credential exposure alerts.
Established password management and access control policies for field and office staff.
Training & Ongoing Monitoring
Conducted employee training focused on phishing recognition and secure data handling.
Deployed 24/7 SOC and SIEM monitoring for continuous threat detection.
Developed a company-specific incident response plan aligned with industry best practices.
The Results
- 7 compromised accounts secured with MFA and strong access policies.
- 3 infected devices reimaged and verified clean.
- 2 fraudulent payment attempts stopped and funds recovered in full.
- 100% email spoofing prevention through new authentication policies.
- 95% phishing reduction within 45 days after AI-based protection was deployed.
- Zero data loss, maintaining customer confidence and operational continuity.
