The Environment
- Microsoft 365 environment for email, calendar, and file sharing
- Frequent communication with clients, lenders, and title companies
- Sensitive transaction details shared via email
- Limited multi-factor authentication enforcement
- No formal monitoring for suspicious login activity
- Users without formal security awareness training
What ITAD4Me Did
- Identified compromised accounts and forced credential resets
- Revoked unauthorized sessions and blocked suspicious sign-in locations
- Reviewed email activity for signs of forwarding rules or data exposure
- Enabled and enforced multi-factor authentication across all users
- Audited mailbox rules and removed malicious forwarding configurations
- Strengthened conditional access policies within Microsoft 365
- Provided guidance on securing client communication workflows
- Implemented monitoring for suspicious login attempts and anomalies
- Delivered targeted user awareness recommendations to reduce future risk
The Results
- Contained the business email compromise before financial loss occurred
- Secured all user accounts and restored control of the environment
- Removed unauthorized access and hidden mailbox rules
- Improved protection for client communications and transaction data
- Reduced likelihood of future phishing or credential compromise
- Increased awareness of email-based attack risks across the team

Background
The business relied heavily on email communication for client interactions, contract coordination, and transaction-related discussions. When suspicious activity was detected, leadership realized that an unauthorized party may have been monitoring communications.
In real estate, timing and trust are critical. Any compromise involving email can quickly escalate into financial risk or client impact.
The Business Risk
The compromised account created multiple immediate risks:
- Exposure of sensitive client communications
- Potential manipulation of wire instructions
- Loss of trust with clients and partners
- Unauthorized access to business data
- Ongoing monitoring by an attacker without detection
Even without confirmed financial loss, the situation required immediate action to secure the environment and prevent escalation.
ITAD4Me’s Approach
ITAD4Me began by identifying the scope of the compromise and securing affected accounts. Unauthorized sessions were revoked, credentials were reset, and suspicious login patterns were reviewed.
Mailbox configurations were audited to identify hidden forwarding rules or persistence mechanisms commonly used in business email compromise attacks.
From there, the focus shifted to strengthening the environment. Multi-factor authentication was enforced, conditional access policies were improved, and monitoring was put in place to detect abnormal activity.
The goal was not only to resolve the incident but to reduce the likelihood of it happening again.
Outcome
The business regained full control of its email environment and eliminated unauthorized access.
The incident was contained before financial loss occurred, and client communications were secured. More importantly, the business now operates with stronger protections, better visibility, and a clearer understanding of email-related risks.
