Construction draw payments are the single highest-value targets for payment diversion fraud. When a subcontractor's email account is compromised, fraudulent banking details slip into pay applications, diverting hundreds of thousands of dollars. Worse yet, when general contractors turn to their cyber insurance policy for reimbursement, carriers frequently deny coverage under warranty exclusions. Here is how general contractors protect their draw payments and maintain bulletproof cyber insurance defensibility.
In commercial construction, millions of dollars move each month through draw requests, progress billings, and subcontractor disbursements. Fraudsters recognize that general contractors operate in high-velocity, deadline-driven environments where accounting teams process dozens of pay applications simultaneously. This makes construction draw payments the premier target for Business Email Compromise (BEC).
The Draw Wire Fraud Playbook
Most contractors assume cyber attacks target their own internal servers. In reality, the vulnerability almost always lies in a subcontractor's compromised email account:
- The Infiltration: A threat actor compromises a trade subcontractor's email system through phishing or credential stuffing.
- The Silent Observation: The attacker monitors project correspondence, learning billing schedules, project manager names, and outstanding draw balances.
- The Altered Pay Application: Right before a scheduled progress payment, the attacker submits an updated invoice or send an urgent notice stating that the subcontractor has switched banking institutions.
- The Wire Diversion: The contractor's accounting team processes the wire to the new routing number. By the time the legitimate subcontractor calls asking why their payment is missing, the funds have been cleared and laundered offshore.
The "Silent Warranty": Why Cyber Insurance Denies Wire Fraud Claims
When a six-figure wire diversion occurs, general contractors expect their commercial cyber insurance policy to cover the loss. Instead, they often face a devastating denial of coverage.
Modern cyber insurance underwriters insert explicit Funds Transfer Fraud Warranties into policies. These clauses legally mandate that the insured must perform independent, dual-channel, out-of-band verification before modifying payment instructions or wiring funds. If the accounting department accepted an emailed PDF, verified via a phone number listed on that same email, or skipped formal verification due to project deadlines, the carrier cites a breach of policy warranty and rejects the claim entirely.
Independent Counterparty Risk Intelligence
Protecting your firm requires separating operational jobsite monitoring from high-value financial verification. While our flagship ConstructQC platform manages daily subcontractor license verification and COI compliance on site, Evulta provides Independent Counterparty Risk Intelligence for high-stakes financial transactions:
- Verified Bank Routing & Signatory Audits: Independent, out-of-band validation of banking credentials directly with issuing financial institutions—completely segregated from email communications.
- Corporate Entity & Good Standing Cross-Referencing: Verifying that the entity receiving wire funds is the exact legal signatory on the master subcontractor agreement.
- Documented Audit Packages: Time-stamped, defensible verification records structured to satisfy cyber insurance policy warranties and eliminate insurer claim denial.
Dual Protection Across Every Active Project
True risk defense for general contractors requires closing both ends of the exposure spectrum: preventing jobsite liability claims through automated license and COI tracking, and eliminating catastrophic wire diversion through rigorous counterparty intelligence.
