    Port cyberattacks from 2011 to 2023: a literature review and discussion of selected cases
    (2024-03-01)
    Senarak, Chalermpong
    Cyberattacks pose a significant threat to seaports worldwide. While numerous scholars have endeavored to address these threats, their findings are often limited in practicality, applying to only a few ports. This paper aims to contribute to the extant literature by presenting and discussing 15 case studies of port cyberattacks that occurred from 2011 to 2023. These cases encompass six instances in Europe, six in America, two in Asia, and one in Africa. The study employs a twofold methodology, consisting of a comprehensive literature review and a personal assessment. Several key insights emerge. First, two primary motivations drive port cyberattacks: (a) the demand for ransom payments and (b) the desire to cause severe disruptions. Second, ransomware was the most common threat used to extort payments, followed by malware and DDoS attacks, which aimed to inflict operational disruption. Third, weaknesses in cybersecurity procedures and a lack of awareness among staff members emerged as significant contributors to cyber vulnerabilities. Forth, ports that quickly detected threats and implemented response measures were able to minimize operational impacts, ensuring the swift resumption of services and the maintenance of service continuity. Fifth, collaborative efforts with external partners and officials expedited response and recovery processes by facilitating threat investigation and solution identification. In light of these findings, it becomes imperative for all ports to develop comprehensive cyber disaster management plans, covering four key phases: preparedness, response, recovery, and mitigation. These plans should encompass three critical aspects of cybersecurity hygiene: human factors, procedural improvements, and infrastructure enhancements. Such practices are instrumental in bolstering a port’s resilience and mitigating the risks associated with cyberattacks.

    Malware Developing Guide: Encryption and Decryption

    This research aims to understand malware from malware author's view. Starting from Ransomware, we attempt to develop ransomware written in python and encrypt all files in Windows platform without doing harm to crucial system files. In this research we use Asus K550J laptop with Windows 10 education (Build 19042) as a victim machine. We ran encryption and decryption program with different privilege and observe the results as well as time takes to encrypt and decrypt files. Results show that encryption process is much slower than decryption process and both encryption and decryption work slower in the bigger file size.
