Credential Stuffing, Procore Vulnerabilities, and the Password Habits That Expose Bid Documents and Project Data
Salt Lake City construction companies are managing more of their business digitally than ever before — project files in Procore, blueprints in Bluebeam Revu, accounting in Sage 300 CRE, and subcontractor communications across a dozen platforms. That digital infrastructure is valuable, and it is protected by something fragile: passwords. A recent Cybernews study analyzing 19 billion exposed passwords found that 94% were reused or recycled across multiple accounts. For a construction company where your project managers, estimators, and field teams are logging into multiple platforms daily, password reuse is not just a habit — it is a wide-open door for attackers who use credential stuffing to move from one compromised account to your most sensitive project data.
What Credential Stuffing Means for a Construction Business
Credential stuffing is an automated attack that takes username-and-password combinations stolen from one data breach and tries them against hundreds of other websites and platforms. The attack succeeds because of password reuse. If your project manager uses the same password for their email, their Procore login, and a retail account that was breached last year, attackers can use that retail breach to walk straight into your project management environment.
Think about what lives in those platforms. Procore holds your project schedules, RFIs, submittals, and subcontractor contact information. Autodesk Construction Cloud holds your design files and coordination models. Sage 300 CRE holds your billing, payroll, and financial records. A credential stuffing attack on any one of these platforms does not just expose data — it can halt your billing operations, expose your bid documents to competitors, and give attackers enough information about your subcontractor relationships to launch targeted wire fraud attacks.
Construction companies are also exposed through their extended networks. General contractors share platform access with subcontractors, architects, and owners — each of those external users is a potential entry point if their credentials are weak or reused. A breach at a subcontractor's account in Procore can give attackers access to your project files just as effectively as a direct breach of your own credentials.
The 'Master Key' Problem on the Job Site
In construction, a master key opens every door. In cybersecurity, a reused password does the same thing. When a single password is shared across a project manager's Procore login, their Sage 300 CRE account, and a personal email account, one breach anywhere becomes a breach everywhere. Automated credential stuffing tools do not stop at one system — they test the compromised credentials against every platform they know your company uses.
Field teams compound this risk. Superintendents and foremen accessing project data on job site tablets and personal phones often use simple, memorable passwords precisely because they are managing multiple logins in demanding physical environments. Those simple passwords are also the easiest to crack and the most likely to be reused. A field team member whose Raken or Procore credentials are compromised can give attackers access to real-time job site data, punch lists, and subcontractor contact lists.
Fix #1: Password Managers Built for Busy Field and Office Teams
The only reliable way to stop credential stuffing is to eliminate password reuse — and the only practical way to do that at scale is with a password manager. Tools like 1Password, Bitwarden, and Dashlane generate and store unique, complex passwords for every platform your office and field teams use. Your project managers only need to remember one strong master password; the password manager handles every other login.
Password managers are practical for construction environments. Mobile-friendly apps work on the same phones and tablets your field teams already carry. Auto-fill features reduce the friction of complex passwords. And because the password manager stores credentials securely, your teams are not writing passwords on job site paperwork or sharing them in text messages — both of which are genuine risks in construction environments.
For companies using Procore, Autodesk Construction Cloud, and Sage 300 CRE, a password manager eliminates the risk that a breach at any one of those platforms cascades into the others. Each platform gets a unique credential, and a breach at one does not unlock the rest.
Fix #2: Multi-Factor Authentication for Project Management Platforms
Multi-factor authentication (MFA) adds a second layer of verification beyond the password — typically a time-sensitive code from Google Authenticator or Microsoft Authenticator — so that even a stolen password cannot unlock an account without physical access to your team member's phone. MFA should be enabled on every platform that holds sensitive project or financial data: Procore, Autodesk Construction Cloud, BuilderTREND, Sage 300 CRE, and any email accounts used for subcontractor communications.
For construction companies, MFA is especially important for accounting and billing platforms. Sage 300 CRE and similar systems hold your company's financial data, payroll records, and billing history. An attacker with access to your accounting system does not need to steal equipment — they can redirect payments, alter vendor records, or extract enough financial information to enable targeted wire fraud against your company or your clients.
Fix #3: Monitor for Credential Exposure
Your company may already have compromised credentials circulating on dark web marketplaces without any visible sign. Proactive dark web monitoring scans for your company's email addresses and associated passwords across breach databases, hacker forums, and dark web markets. When a match is found, your team can respond immediately — changing the compromised credentials before attackers use them.
This is particularly important for construction companies with high employee turnover, where former employees' credentials may remain active in project management platforms long after they have left the company. A former project manager's active Procore credentials are a standing security risk that credential monitoring and prompt offboarding procedures can close.
What Your Construction Company Should Do This Month
- Audit password practices across your office and field teams — are project managers reusing passwords?
- Deploy a password manager firm-wide and enforce unique passwords for Procore, Sage 300 CRE, Autodesk, and all other platforms
- Enable MFA on Procore, Autodesk Construction Cloud, BuilderTREND, Sage 300 CRE, and all email accounts
- Run a dark web credential check on your company's domain
- Review subcontractor access in Procore — remove access for former subcontractors and enforce credential standards for active ones
Protecting Your Competitive Advantage
Your bid documents and project estimates represent significant investment — time, expertise, and competitive intelligence. If a competitor gains access to your Procore environment through a credential stuffing attack, they can see your pricing, your subcontractor relationships, your project schedules, and your bid strategy. In a competitive bidding environment, that information is genuinely valuable to a rival.
Time is money in construction, and that applies to cybersecurity as well. The time your office and field teams lose recovering from a credential compromise — locked out of Procore, resetting Sage accounts, notifying subcontractors — is time not spent keeping projects on schedule and on budget. A small investment in password management and MFA is a fraction of the cost of a single credential stuffing incident.

Frequently Asked Questions
Q: How do we manage passwords for field teams who aren't tech-savvy?
This is the most common concern we hear from construction companies, and it is entirely solvable. Modern password managers like 1Password have mobile apps designed for non-technical users. Setup involves installing the app and having your IT provider pre-configure it with your company's platforms. Once set up, the experience for a field team member is simple: the app auto-fills login credentials when they open Procore or Raken on their phone. Most field team members adapt quickly because the app actually makes logging in easier, not harder. Qualit handles the initial configuration and training for your entire team.
Q: What about subcontractors who access our Procore environment — are they a security risk?
Yes — subcontractor access is one of the most common credential security gaps in construction. Subcontractors who access your Procore environment with weak or reused passwords can become an entry point for attackers, even if your own team's credentials are secure. Best practices include requiring subcontractors to use MFA when accessing your Procore environment, limiting subcontractor access to the specific projects they are working on, and promptly removing access when a subcontract ends. Procore supports role-based access controls that make this manageable even with a large subcontractor network.
Q: Can credential stuffing attacks affect our Sage 300 CRE accounting system?
Yes — and Sage 300 CRE is a particularly high-value target precisely because it holds financial records, payroll data, and billing information. Any cloud-accessible accounting system is subject to credential stuffing if the login credentials are reused from another breach. Enabling MFA on Sage 300 CRE and ensuring that every user has a unique password for the platform (managed through a password manager) are the two most important steps for protecting your financial data.
