How Should Manufacturing Companies Prepare for Ransomware and Business Email Compromise?
Manufacturing companies should prepare for ransomware and business email compromise by putting five controls in place first: MFA, email security, endpoint protection, tested backups, and security awareness training. Together, these make it harder for attackers to get in, limit how far they can spread, and give you a way to recover without paying.
Why Manufacturers Are Targeted
Manufacturers manage payments, vendors, production schedules, customer data, and systems that cannot afford prolonged downtime. Attackers know that pressure to restore production can push companies to pay quickly.
Common Threats
- Ransomware: Encrypts systems and data, often halting production until systems are restored.
- Business email compromise: Attackers take over or impersonate an email account to redirect payments or steal information.
- Credential theft: Stolen passwords give attackers a quiet way into email, ERP, and remote access.
- Invoice fraud: Fake or altered vendor invoices trick accounts payable into paying the wrong account.
- Phishing: The most common starting point for all of the above.
The Protection Framework
- Prevent: Block common entry points with MFA, email filtering, and patching.
- Detect: Monitor endpoints and accounts for unusual activity.
- Contain: Isolate affected systems quickly to limit spread, starting with securing production-critical systems.
- Recover: Restore from backups that have been tested.
- Document: Record what happened and what changed, which also supports insurance claims.
Controls to Prioritize
- MFA
- Email security
- Endpoint protection
- Backup testing
- Security awareness training
These controls map closely to the cyber insurance requirements for manufacturers carriers now review. Keep them current with regular cybersecurity risk and backup reviews.
Build Your Response Plan
Decide ahead of time who makes decisions during an incident, how you will communicate if email is down, and how payment changes get verified. These steps belong in your manufacturing incident response planning.
Frequently Asked Questions
What is business email compromise?
Business email compromise is when an attacker takes over or impersonates a company email account to redirect payments, request sensitive data, or trick employees into acting.
How can manufacturers stop invoice fraud?
Verify any change to vendor payment details by calling a known phone number, require approval for new payment instructions, and train accounts payable to spot pressure tactics.
Should a manufacturer pay a ransomware demand?
That decision should involve leadership, legal counsel, and your insurer. Tested backups and an incident response plan give you options besides paying.
How often should employees get security awareness training?
Train at least annually, with shorter refreshers and phishing simulations throughout the year.
