What happened to this construction company's email?

A Washington construction company with 6 office users and 6 shared jobsite kiosk accounts suffered a business email compromise (BEC). An attacker gained access to company mailboxes, which put invoices, vendor payments, and bid communications at risk.

The company had no managed IT provider and no documented security baseline. It called inTech Consulting to contain the incident, remove the attacker, and put controls in place so it would not happen again.

Why is business email compromise so dangerous for contractors?

Business email compromise is the most expensive category of cybercrime reported to the FBI. The FBI Internet Crime Complaint Center (IC3) recorded nearly $2.8 billion in BEC losses in its 2024 Internet Crime Report, far more than ransomware.

Construction firms are a favorite target because money moves by email. Progress billings, change orders, subcontractor payments, and supplier remittance details all travel through the inbox. One altered bank routing number on a pay application can redirect a six-figure draw.

How did inTech scope the cleanup?

inTech scoped the remediation at 18 labor hours: 2 hours per full user account and 1 hour per kiosk account. Every one of the 12 accounts was treated as potentially compromised until proven clean, because attackers who get into one mailbox routinely pivot to others.

The project was led by inTech Security Technician Victoria Chevalier, with a dedicated project manager running kickoff, execution, and completion checkpoints.

What are the steps in a business email compromise cleanup?

A BEC cleanup has four jobs: cut off the attacker, find what they changed, close the door they used, and confirm the system is clean. inTech's process for this engagement followed that order.

  1. Contain. Reset credentials on all 12 accounts and revoke every active sign-in session so stolen passwords and session tokens stop working immediately.
  2. Investigate. Review sign-in logs and mailbox audit logs for foreign or impossible-travel logins, and identify which accounts the attacker actually touched.
  3. Remove persistence. Hunt for the attacker's hidden footholds: malicious inbox rules that forward or delete mail, unauthorized mail forwarding, rogue app consents, and newly registered sign-in methods.
  4. Harden. Enforce multi-factor authentication (MFA) on every account, including shared kiosks, and apply preventative controls to block the same attack path.
  5. Validate and resume. Confirm normal mail flow, confirm no unauthorized access remains, and walk the team through what a suspicious payment request looks like.

Think your mailbox might be compromised? Unexplained inbox rules, vendors asking about emails you never sent, or password reset alerts you did not request are all warning signs. Talk to inTech today.

What results did the cleanup target?

What happened after the incident was closed?

The company moved to a fully managed security and IT agreement with inTech on a 2-year term, starting September 16, 2026. An incident is the most expensive way to discover you need a security baseline, and the managed agreement keeps that baseline in place.

The agreement covers all 6 office users as fully managed seats and the 6 kiosk accounts at a lighter support tier, since frontline crews only need limited access. It also includes a yearly allocation of project hours at no added labor cost, so follow-up hardening work does not require a new quote each time.

How much does managed IT with security cost for a small construction company?

inTech's Managed IT is published at $200 to $250 per user per month, with cybersecurity included, not sold as a separate line. For a 6-person office, that puts the fully managed range at roughly $750 to $1,350 per month before licensing.

Full pricing, including co-managed IT at $75 to $150 per user per month, is on our IT services cost page.

What should a construction company do first after a BEC?

Call your bank first if any payment went out, then call your IT provider. Banks can sometimes recall a wire if contacted within hours, and the FBI's IC3 Recovery Asset Team works directly with financial institutions on reported BEC transfers.

After that, do not just reset the one password you know about. Treat every account as suspect, remove inbox rules, and turn on MFA everywhere. Learn more about how we support contractors on our construction IT page and our cybersecurity services page.

Frequently asked questions

What is business email compromise?

Business email compromise (BEC) is an attack where a criminal gains access to, or impersonates, a company email account to redirect payments or steal information. The FBI IC3 reported nearly $2.8 billion in BEC losses in 2024.

How long does a business email compromise cleanup take?

For a small business, a BEC cleanup typically takes one to three days of work. This engagement was scoped at 18 hours for 12 accounts: 2 hours per full user and 1 hour per kiosk account.

Is resetting the password enough after an email account is hacked?

No. Attackers often leave inbox rules, mail forwarding, and active sessions that survive a password reset. A proper cleanup revokes sessions, removes persistence, and enforces multi-factor authentication on every account.

Why are construction companies targeted by email fraud?

Construction payments move by email. Pay applications, change orders, and supplier remittance changes are routine, so a fraudulent request to update bank details looks normal to accounts payable.

How much does managed IT with cybersecurity cost for a small business?

inTech publishes Managed IT at $200 to $250 per user per month, and cybersecurity is included. For a 6-person office that is roughly $750 to $1,350 per month before software licensing.
