BEC – Business Email Compromise

How Green Computer Systems Rescued Lum’s Sales and Service from an Email Security Nightmare

Imagine this: you’re running a thriving business, and suddenly your customers start receiving fraudulent invoices that redirect their payments to scammers. That’s exactly what happened to Lum’s Sales and Service, a respected company in Eastern Oklahoma. They were victims of a Business Email Compromise (BEC), a sophisticated cyberattack that threatened their reputation and revenue.

At Green Computer Systems (GCS), we specialize in managed IT services for small and midsize businesses. When Lums Sales and Service reached out, they needed immediate help to secure their email systems and restore trust with their customers. Here’s how we turned their crisis into a success story.

Identifying the Problem: A Compromised Email System

Lums Sales and Service’s previous email provider was underperforming and lacked essential security features. Without proper encryption and authentication protocols, their system was vulnerable to cyber threats. Fraudulent emails were slipping through, and their customers were at risk.

The Solution: Migrating to Google Workspace with Enhanced Security

We knew that migrating their email to Google Workspace would provide the robust security and reliability they needed. Over a single weekend, we transferred 261,701 emails—over 105 GB of data—to their new, secure accounts. We didn’t just move the data; we optimized it by pruning back to five years’ worth of essential information, ensuring faster access and better organization.

Implementing Advanced Security Measures

To prevent future attacks, we added proper encryption along with DKIM and DMARC records. These protocols authenticate outgoing emails, reducing the risk of fraudulent messages reaching customers. It’s a crucial step in preventing business email compromise attacks.

Integrating with QuickBooks for Seamless Invoicing

But we didn’t stop at email migration. We integrated their new email system directly with QuickBooks. Now, Lums Sales and Service can send invoices swiftly and securely, streamlining their billing process and enhancing customer satisfaction.

The Results: A Secure, Efficient, and Reliable System

By entrusting their IT needs to GCS, Lums Sales and Service now enjoys:

• Enhanced Security: Robust measures protect against cyber threats.
• Improved Efficiency: QuickBooks integration speeds up invoicing.
• Reliable Communication: Google Workspace offers dependable email services.
• Cost Savings: Outsourcing IT services is more affordable than hiring full-time staff.

Plenty of Available Storage after Migration
