How Manufacturers Can Defend Against Credential Theft

In modern manufacturing, data and uptime are everything. From ERP systems to vendor portals, every login holds the keys to production, supply chain visibility, and customer trust.

That’s why credential theft—the stealing of usernames and passwords—has become one of the biggest cybersecurity threats facing manufacturers today.

According to Verizon’s 2025 Data Breach Investigations Report, over 70% of breaches involve stolen credentials. The fallout can include stolen designs, production delays, ransom payments, and long-term reputational damage.

For Idaho manufacturers, where downtime and compliance risks can ripple through entire supply chains, securing employee and vendor logins is no longer optional—it’s mission critical.

What Is Credential Theft and How Does It Happen?

Credential theft isn’t one quick hack—it’s a slow, layered attack. Cybercriminals use multiple methods to steal login information and gain silent access to critical systems:

• Phishing Emails: Fake emails that trick employees into revealing credentials through convincing login screens or links.

• Keylogging: Malware that records every keystroke entered on infected devices.

• Credential Stuffing: Attackers use stolen logins from other breaches to access manufacturing systems that share passwords.

• Man-in-the-Middle (MitM) Attacks: Hackers intercept login data sent over unsecured Wi-Fi or vendor connections.

Once inside, attackers can lock down production systems, steal intellectual property, or even manipulate supplier orders—all without being noticed.

Why Traditional Passwords Aren’t Enough

Many manufacturers still depend on old-school username and password logins. But that approach is no longer safe because:

• Passwords are often reused across systems.

• Employees choose weak or guessable passwords.

• Phishing attacks easily capture credentials.

As attackers grow more advanced, it’s time for manufacturers to evolve past password-only protection.

What Are the Best Ways to Protect Manufacturing Logins?

The key is layered protection—using multiple methods that work together to prevent, detect, and contain credential theft.

1. Multi-Factor Authentication (MFA)

MFA adds an extra verification step—like a text code, fingerprint, or physical security key—to confirm identity.

• Works across ERP, MES, and vendor systems.

• Hardware keys and app-based tokens (like Duo or YubiKey) are highly resistant to phishing.

2. Passwordless Authentication

The future of manufacturing security means fewer passwords altogether:

• Biometrics: Facial or fingerprint recognition.

• Single Sign-On (SSO): One secure login for multiple tools.

• Push Notifications: Approve or deny logins from a secure mobile app.

3. Behavioral Analytics and Anomaly Detection

AI-based tools monitor login behavior, flagging unusual patterns like:

• Logins from unfamiliar devices or locations.

• Multiple failed attempts.

• Access at odd hours or from foreign IPs.

These alerts allow IT teams to act before major damage occurs.

4. Zero Trust Security

Zero Trust means “never trust, always verify.”
Even internal users must continuously prove their identity before accessing any data or machinery system. It’s especially effective in OT/IT hybrid environments, where production equipment connects to corporate networks.

5. Train Your Employees

Technology can’t fix what human error creates. Most breaches start with one wrong click.
Train your teams to:

• Spot phishing emails.

• Use password managers.

• Avoid reusing credentials.

• Understand why MFA is mandatory.

Why Manufacturers Can’t Wait to Upgrade Security

Credential theft is no longer a “what if”—it’s a “when.”
Attackers are adapting faster than most plants can patch. Each login, from a vendor portal to a machine operator account, is an entry point.

By implementing MFA, adopting Zero Trust architecture, and reinforcing cybersecurity awareness, manufacturers can stop credential theft before it stops production.

FAQs About Credential Theft in Manufacturing

Q: Why are manufacturers a top target for credential theft?
Because their systems control physical operations, attackers can cause massive disruption—and they know most plants rely on outdated authentication methods.

Q: What’s the first step to prevent credential theft?
Start with Multi-Factor Authentication. It’s the fastest and most cost-effective defense.

Q: Can phishing filters stop all credential theft?
No. Filters help, but attackers constantly evolve tactics. That’s why layered defense and user training are key.

Q: What’s the difference between MFA and Zero Trust?
MFA verifies users at login, while Zero Trust verifies continuously—every time a request is made.

Q: How can manufacturers protect remote workers and vendors?
Require VPN access, enforce MFA, and monitor connections for unusual activity.
