Cybersecurity<\/a> for construction companies<\/a> means protecting project data, payments and job site devices from fraud, ransomware and downtime. The most important steps are multi-factor authentication (MFA), payment verification rules, secure mobile devices<\/a>, tested backups<\/a> and staff training.<\/p>\n

Construction firms move large payments, work with many subcontractors and rely on tablets and phones in the field. That combination makes them a frequent target. This guide covers the biggest threats and practical steps for contractors on Seattle’s Eastside and beyond.<\/p>\n

Why are construction companies targeted by cybercriminals?<\/h2>\n

Construction companies handle progress payments, change orders and supplier invoices every week. Criminals know that a single fake payment request can redirect a large sum. Projects also involve many outside parties, from subcontractors to architects<\/a>, which gives attackers more ways in. Tight schedules mean downtime is costly, so firms may feel pressure to pay ransoms.<\/p>\n

What are the top cyber threats to construction companies?<\/h2>\n

How does payment and invoice fraud work?<\/strong><\/h3>\n

Criminals send emails that look like they come from a supplier or subcontractor and ask to change bank details. If the change is not verified, the next payment goes to the criminal’s account.<\/p>\n

Why is ransomware a risk for contractors?<\/strong><\/h3>\n

Ransomware can lock estimating, scheduling, accounting and project management systems. Without them, crews cannot get plans or updates, and billing stops.<\/p>\n

What makes phishing effective in construction?<\/strong><\/h3>\n

Phishing emails often copy bid invitations, plan rooms, permit notices or shipping updates. One click can give criminals a password or install malware.<\/p>\n

Why are mobile devices a weak spot?<\/strong><\/h3>\n

Tablets and phones used on job sites hold plans, photos, contacts and email. They are easy to lose and often connect to unsecured networks.<\/p>\n

How can subcontractor access create risk?<\/strong><\/h3>\n

Shared logins and broad access for outside partners can expose project data. When a partner is hacked, your data may be exposed too.<\/p>\n
