Real Estate Cybersecurity & Wire Fraud Protection in Canada

Business email compromise is the single largest cybercrime threat facing Canadian real estate professionals. Attackers compromise a realtor's, lawyer's, or mortgage broker's email account, monitor transaction communications over days or weeks, then intervene at closing — sending fraudulent wire transfer instructions that appear to come from a trusted party. Average loss per incident exceeds $100,000. FINTRAC-regulated brokerages are prime targets because transaction values are large and payment instructions change frequently.

The attack pattern: attacker compromises one email account in the transaction chain (often a realtor or conveyancing lawyer). They monitor silently, learn the names of all parties, the expected closing date, and the financial institution. Days before closing, they send wire instructions — using the compromised account or an impersonation address — redirecting funds to a fraudulent account in a foreign jurisdiction. By the time the fraud is detected, the funds are gone.

Quantm monitors for account compromise indicators (impossible logins, new forwarding rules, session anomalies), enforces MFA on all transaction-related accounts, and alerts on suspicious patterns that match BEC targeting behaviour. We also prepare BEC-specific incident response procedures so staff know exactly what to do if they receive suspicious payment instructions.

Five steps to protect a real estate transaction from BEC: (1) Verify all wire instructions by phone call to a number sourced independently — never from an email. (2) Enable MFA on every email account in the transaction chain. (3) Monitor for forwarding rules set on staff email accounts. (4) Implement DMARC to prevent domain impersonation. (5) Brief clients at the start of every transaction on the risk of fraudulent payment instructions.
