Zero Day Cyber Crime Investigation

Abstract -This paper puts forward a full Zero-Day Cybercrime Response Framework aimed at India. It requires Digital Service Providers, or DSPs, to hand over requested metadata to investigators in just 30 minutes. The setup pulls together legal, technical, operational, and enforcement parts to speed up law enforcement against new cyber-attacks. It draws from India's current IT laws, like the IT Act from 2000 and the IT Rules of 2021, plus newer stuff such as the Data Protection Act of 2023 and CERT-In guidelines. This way, DSPs meet quick data demands while still protecting privacy. Main pieces involve automatic spotting of incidents, safe ways to get data, and checks from groups like CERT-In, the Ministry of Home Affairs or MHA, and the National Cybercrime Reporting Portal, known as NCRP. We look at how this stacks up against other countries' approaches, say China's Cybersecurity Law, the EU's e-evidence system along with GDPR, and US methods including the CLOUD Act and tools for endpoint detection. From that, we pull useful ideas and make sure it fits global norms. Figure 1 shows a flowchart of the whole process. We spot likely problems, things like data staying local, court supervision, and issues across borders. Then we talk about fixes, using AI for analysis, legal protections, and deals between nations. Overall, our look shows that a solid 30-minute rule for metadata, backed by tech automation and clear rules, could really boost India's handling of cybercrimes. And it does this without stepping too hard on personal rights.
