How IPDR is transforming cybercrime investigations in India

As cybercriminals increasingly use encrypted apps and internet-based platforms, police are relying on Internet Protocol Detail Records (IPDR) to track digital activity. Investigators use IPDR metadata alongside AI-powered analysis to solve cyber fraud, phishing, ransomware and other online crime cases

Hyderabad: For years, Call Detail Records (CDR) have been integral to police investigations, helping investigators trace phone calls and text messages. But as cybercriminals shift from conventional calls to encrypted messaging apps, online banking and social media platforms, investigators are increasingly relying on Internet Protocol Detail Records (IPDR), a key source of digital evidence that tracks internet activity.

With cyber fraud, phishing, cyberstalking, ransomware and online harassment on the rise, IPDR has become an essential tool for law enforcement. Unlike CDR, which records voice calls and SMS, IPDR captures metadata such as the IP address assigned to a device, websites or servers accessed, session timings, ports used and the volume of data transferred. Though it does not reveal the contents of messages or calls, it helps investigators piece together a suspect’s online activity.

“Cybercrime investigations today depend more on metadata than on message content. Even if communication is encrypted, every internet session leaves behind a digital trail that can be analysed to establish online activity,” a senior official of the Cyber Crime Police said.

Officials said internet service providers generate and store IPDR logs through their network systems. These records are shared with investigating agencies only after lawful requests and help identify the subscriber, device or internet session linked to a suspected offence.

The official said IPDR plays a crucial role in probing phishing attacks, online banking fraud, cyberstalking, anonymous social media abuse, ransomware and child exploitation cases. “In financial fraud cases, IPDR helps us establish when a device connects to a bank’s server or a fraudulent website, allowing investigators to reconstruct the sequence of events,” the official added.

Investigators match IPDR data with CDR, subscriber details, device identifiers, tower location data, Wi-Fi logs, open-source intelligence and CCTV footage to build a digital profile of suspects. The records also help trace anonymous social media accounts, identify connections to suspicious servers and establish links between members of organised cybercrime groups.

As cybercrime investigations now involve millions of internet session records, police are increasingly using artificial intelligence-based tools to analyse IPDR data. “Manual analysis of these records takes considerable time. AI-based platforms can quickly correlate different datasets, rebuild timelines and detect suspicious patterns, making investigations faster and more accurate,” the official explained.

Officials said that as internet-based communication continues to replace conventional phone calls, IPDR has become one of the most important sources of digital evidence, helping investigators determine when a person was online, the services accessed and the digital trail left behind during an investigation.
