Manufacturing Cybersecurity Must Adapt to Emerging Technology and Threats

At the 2019 National Association of Manufacturers’ Board Meeting, guest speaker, Ron Moultrie leveraged his career long experience with NSA, CIA and Air Force to identify manufacturers as a top target of espionage. As he summarized: “Growth and economic strength of a nation is measured by its manufacturing.” And he further postulated that nearly one-third of all cyber attacks everyday are against a domestic manufacturing firm.

As Moultrie implies, nation state actors are hard at work stealing vital manufacturing IP and processes in order to help their country further its economic agenda. This is not simply an issue for nation security to deal with. Simple smash-and-grab criminals peddling fraudulent invoices, or more crafty criminal syndicates know manufacturers will pay to avoid operational disruption and the accompanying financial losses and reputational damage. And law enforcement struggles to stop attacks who reside outside the country in places with destabilized governments and no extradition. These attacks will continue and these forms of crime pay well, but unlike other forms of lucrative crime, most cyber criminals act with impunity.

Today, these criminals are hunting their prey. Through the opportunistic and transactional ransomware attacks of the past few years, criminals identified more lucrative prey, such as law firms, healthcare institutions and manufacturers. Law firms learned this lesson in April 2018 when the FBI identified a well-known Chinese threat group targeting law firms to steal information that was later used to defraud large financial institutions.

Manufacturers of all sizes are targets. Criminals don’t discriminate by size and regulators are impartial to employee count or annual revenue. Smaller and midsized businesses still manage lucrative assets, funds and information, and are easier targets than their larger peers.

A Midwest manufacturer of a well-known brand was attacked by hackers who used the moniker Dark Overlord, who claimed that they had stolen a wealth of company and personal employee information. The hackers published nearly 200GB of financial spreadsheets, invoices, banking contracts, presentations, and product designs after the firm refused to meet their extortion demands. [1] Another Silicon Valley firm was defrauded of nearly two million dollars in venture capital, 24 hours after posting a press release about their round of funding. And these forms of data breaches are expensive. Information Week reported that breaches against Foxconn, Honda and Boeing each cost between $3.5 and $6.0 million to clean up.[2]

The vast majority of attacks begin with a simple email phishing campaign designed to harvest an employee’s credentials or elicit fraudulent payment requests (called business email compromise or spoofing the boss).

Cybersecurity firm Cyren reportied in July 2018 that 93 % of the attacks they identified against manufacturers originated with some form of phishing campaign. [3] Phishing campaigns are often used to deliver ransomware that locks files and demands payments in cryptocurrency.

Criminals also exploit systemic vulnerabilities in operating systems or control systems like SCADA and ICS. The 2018 Forrester SCADA Survey indicates that 56% of organizations using SCADA or ICS systems have experienced a breach in the past year. Only 11% indicate that they have never experienced a breach. [4] This finding suggests that many manufacturers don’t know or aren’t willing to acknowledge that they’ve been attacked and infiltrated. A successful cyber attack against OT or a SCADA control system not only has the potential to damage the business financially, but also could result in physical consequences to such things as infrastructure and services, the environment, and possibly human life.

In 2018, eSentire commissioned independent research that interviewed nearly 1,300 senior IT and security executives, of which 200 worked in manufacturing. Manufacturing firm’s self-ranked above financial institutions when it came to vulnerability to cybersecurity attacks, but below law firms and healthcare institutions. Over half of the respondents reported that unknown attacks posed the greatest risk, followed by non-malware born attacks and insider actions. [5]

Manufacturing firms also recognized that cybersecurity is now a board level issue, but struggle to cope with the growing challenges of mitigation cyber risk. Managing the supply chain (59%), meeting regulatory and customer requirements (58%), and bearing the cost of ever-increasing security demands (50%) represented the top challenges. To compound the issue, 42% of firms were challenged to measure and report the status of security programs, and 46% struggled to demonstrate the value of cybersecurity spend to executives and board members. [5]

Manufacturing firms are among the fastest to adopt emerging technologies such as cloud (78%), big data analytics (56%) and IoT/IIoT (54%). In response, cloud security investment was a top priority (41%), with a focus on identity access management (43%), endpoint protection (34) and a new focus on threat detection and response services (31%). While spend parallels technology and employee risks, the majority (43%) of firms primarily base their security efforts on traditional prevention technologies (firewalls and anti-virus), with 36% leverage compliance logging and alert management tools and services, and the smallest contingent (20%) are investing in artificial intelligence used to detect aberrant activity, proactive threat hunting and threat intelligence. In the next two years, 43% intend to leverage these proactive hunting and predictive detection and response practices to improve their security posture. [5]

Attacks on manufacturing firms will only continue to increase as operational (OT) and information systems (IT) converge and blend into one ecosystem. There are no magic bullets, but firms can follow this top ten security must have list to reduce the risk and improve their ability to respond and recover from an attack.

Security Top Ten

  1. Identify and audit critical systems and data. Protect what matters.
  2. Understand your obligations (legal, regulatory, supply-chain, and client).
  3. Establish cybersecurity policies, procedures and executive reporting mechanisms.
  4. Conduct an annual risk assessment and security readiness exam (penetration testing, red-blue team exercises)
  5. Require encryption of stored data (mobile devices, laptops, servers, etc.).
  6. Use VPN security to protect data and user credentials in motion through a virtual private network.
  7. Establish mobile and bring your own device (BYOD) rules and controls to enforce strong passwords and limit access to corporate assets.
  8. Establish back-up systems and services.
  9. Establish an incident response plan and team, and practice fire drills to hone your program.
  10. Consider cyber insurance to cover investigation, disruption, lost revenue, and other costs not covered in non-cyber specific policies.
