Cochin Shipyard Limited (CSL)

In May 2023, Cochin Shipyard Limited (CSL), India’s largest shipbuilding and maintenance facility, fell victim to a denial-of-service (DoS) attack orchestrated by a hacktivist group. The assault targeted the company’s official website, rendering it temporarily inaccessible. While the disruption was brief and the site was swiftly restored to full functionality, the incident highlighted vulnerabilities in the yard’s digital infrastructure. The attack did not result in data breaches, financial losses, or operational halts in shipbuilding activities, as the core systems remained unaffected. However, the temporary unavailability of the website may have caused minor reputational concerns, particularly given CSL’s status as a critical defense and commercial shipyard under the Government of India. The incident underscored the growing threat of cyber activism targeting high-profile industrial and strategic entities, even when the immediate impact is limited to surface-level disruptions.
