Experiences and Lessons Learned at a Small and Medium-Sized Enterprise (SME) Following Two Ransomware Attacks

Experiences and Lessons Learned at a Small and Medium-Sized Enterprise (SME) Following Two Ransomware Attacks

Donald Wynn, Jr., W. David Salisbury, Mark Winemiller
This paper presents a case study of a small U.S. manufacturing company that suffered two distinct ransomware attacks four years apart, despite strengthening its cybersecurity after the first incident. The study analyzes both attacks, the company's response, and the lessons learned from the experiences. The goal is to provide actionable recommendations to help other small and medium-sized enterprises (SMEs) improve their defenses and recovery strategies against evolving cyber threats.

Problem Small and medium-sized enterprises (SMEs) face unique cybersecurity challenges due to significant resource constraints compared to larger corporations. They often lack the financial capacity, specialized expertise, and trained workforce to implement and maintain adequate technical and procedural controls. This vulnerability is increasingly exploited by cybercriminals, with a high percentage of ransomware attacks specifically targeting these smaller, less-defended businesses.

Outcome - All businesses are targets: The belief in 'security by obscurity' is a dangerous misconception; any online presence makes a business a potential target for cyberattacks.
- Comprehensive backups are essential: Backups must include not only data but also system configurations and software to enable a full and timely recovery.
- Management buy-in is critical: Senior leadership must understand the importance of cybersecurity and provide the necessary funding and organizational support for robust defense measures.
- People are a key vulnerability: Technical defenses can be bypassed by human error, as demonstrated by the second attack which originated from a phishing email, underscoring the need for continuous employee training.
- Cybercrime is an evolving 'arms race': Attackers are becoming increasingly sophisticated, professional, and organized, requiring businesses to continually adapt and strengthen their defenses.
