Cyberterrorism, a transnational issue, requires effective international and regional laws. Initiatives like the Budapest Convention on Cybercrime, UNODC Global Program on Cybercrime, and UNSC Resolutions (1373, 57/239, 1624, and 2462) aim to address this global problem. However, challenges persist due to divergent national laws, jurisdictional complexities, and time-sensitive digital evidence. Effective cooperation requires accelerated data preservation, 24/7 points of contact, and specialized tools. As AI and quantum technologies evolve, so do threats, necessitating concerted responses, multilateral coordination, and technological resilience investments to counteract cyber threats to critical information infrastructure all while balancing law enforcement with human rights and sovereignty concerns.
