OT/IT Cybersecurity | Password Security | IT Support for Manufacturers Salt Lake City
Introduction
Every day, your operations team logs into SAP, Epicor, Microsoft Dynamics 365, or whichever ERP platform runs your production floor. Those credentials are the keys to your production schedules, supplier records, pricing data, and proprietary manufacturing files. Most plant managers and operations directors do not think twice about whether the password an employee uses for the ERP is the same one they use for a personal account somewhere else — but attackers track exactly that. Credential stuffing is a growing threat to manufacturing operations, and one compromised password can bring your production line to a standstill.
What Is Credential Stuffing — and Why Should Manufacturers Care?
Credential stuffing is not traditional hacking. Attackers do not brute-force their way through your firewall. They collect usernames and passwords from previous data breaches — billions of them are available on the dark web — and then run those combinations automatically against other systems, including ERP platforms, CAD software portals, and SCADA system interfaces.
A 2024 Cybernews study analyzed nearly 19 billion exposed passwords and found that 94% were reused or duplicated. That means virtually every password in circulation has likely appeared in a breach somewhere else.
For a manufacturing operation, the risk is concrete: a shop floor employee uses the same password for your Epicor system that they used for an online account breached two years ago. They have no idea. An attacker runs automated tools against your ERP login, gets in, and now has access to production data, supplier contracts, and potentially your network. Uptime is non-negotiable — and a credential compromise that locks your operations team out of the ERP makes it immediately negotiable.
The One-Breach-Is-the-Master-Key Problem in Manufacturing
Manufacturing environments typically involve multiple interconnected systems: an ERP like SAP or Oracle for production planning, CAD tools like AutoCAD or SolidWorks for design files, and potentially SCADA systems that interface with production equipment. If your team reuses passwords across these platforms, a single compromised credential does not just expose one system — it exposes the entire operational stack.
The convergence of OT (operational technology) and IT in modern manufacturing means that a cyber compromise is not just a data problem. It can be a production problem. Attackers who gain access to ERP credentials can manipulate production schedules, exfiltrate proprietary CAD files, or position themselves for a ransomware deployment that halts the line entirely.
Three Things Every Manufacturing Operation Should Implement
1. Deploy a Password Manager Across Your Operations Team
Password managers like 1Password, Bitwarden, and Dashlane generate unique, complex passwords for every system your team accesses — SAP, Epicor, AutoCAD portals, supplier portals, and every other platform. No one needs to remember them. The manager stores and auto-fills them securely.
For a manufacturing organization, this means even shop floor employees with system access are using credentials that cannot be guessed or reused from a previous breach.
2. Enable Multi-Factor Authentication on Critical Systems
MFA means that even if a password is compromised, an attacker cannot access your ERP or other production systems without a second factor — typically a code from Google Authenticator or Microsoft Authenticator. Most enterprise ERP platforms support MFA natively. If yours does, it should be turned on for every user with access to production data or financial records.
MFA stops credential stuffing attacks entirely. A stolen password without the second factor is useless to an attacker.
3. Audit Access by Role and Remove What's Not Needed
Not every operator needs access to every module of your ERP. Not every employee needs access to CAD files or supplier contracts. Segment access by role, and when an employee leaves or changes roles, remove or adjust credentials immediately. This is standard access control — and it significantly limits the blast radius if any single credential is compromised.
A Note on OT/IT Convergence and Password Risk
Many manufacturers have SCADA systems and industrial control systems (ICS) that were originally designed as isolated operational technology. As those systems increasingly connect to IT networks — and to the internet — they inherit IT security risks, including credential-based attacks. Default passwords on SCADA interfaces and network-connected equipment are a known and well-documented attack vector. A password management strategy for your manufacturing environment must include these systems, not just office computers.
Frequently Asked Questions
Q: Is credential stuffing really a risk for manufacturing companies, or is this more of a retail/finance problem?
Manufacturing is one of the most targeted sectors for cyberattacks — consistently ranking in the top two or three industries in annual threat reports. The combination of valuable IP, complex supply chains, OT/IT convergence, and often-underfunded security programs makes manufacturers attractive targets. Credential stuffing is a low-effort, high-yield attack method that works regardless of industry.
Q: Our ERP vendor says the platform is secure. Doesn't that mean our credentials are protected?
Platform security and user credential hygiene are separate issues. Your ERP vendor secures the software architecture — they cannot control whether your employees reuse passwords that have already been exposed in other breaches. That protection has to come from your own password practices.
Q: What happens if an attacker gets into our SAP or Epicor system?
Consequences range from data exfiltration (production data, supplier contracts, proprietary specs) to ransomware deployment that encrypts your ERP and halts production. Every minute of production downtime has a real dollar cost. Recovery can take days to weeks without proper preparation.
