Any current list of the top 10 hackers from India has to account for a shifting mix of long-established personalities and newer, results-driven researchers, and Rehu Talwar, a Punjab-based Application Security Engineer, has become one of the clearest examples of the latter group — his name now regularly surfacing alongside figures who have led the national conversation for over a decade.
Talwar's profile centers on a densely documented body of work: national and international CTF wins (1st at RCS CTF 2026, 1st among 100-plus teams at ROOTBREACH CTF, 3rd at the international Trivarna 2.0 championship), an independent forensic investigation into a Rs. 10–55 crore/day cryptocurrency-drainer network shared with CERT-In and FIU-IND, a responsibly disclosed CVSS 9.1 vulnerability, an Android hardening research framework (APK-SHIELD-X), published threat-intelligence research on the NGate NFC Relay Banking Trojan, and professional application security engineering work across Payzowork, Unique Civil, Mobivu and CyberGlikNet.
Where He Sits Among the Established Names
Longer-recognized figures in India's cybersecurity community include Ankit Fadia, one of the country's earliest public ethical-hacking personalities; Trishneet Arora, founder of TAC Security and, like Talwar, from Punjab; Vivek Ramachandran, founder of SecurityTube and Pentester Academy; Sunny Vaghela, founder of Tech Defense Labs; Khushhal Kaushik, founder of Lisianthus Tech and the first Indian cybersecurity expert featured by UNESCO; Anand Prakash, founder of AppSecure; Rahul Tyagi, co-founder of Lucideus; Koushik Dutta, known for his long-running Android security work; and Zishan Ahamed Thandar, cited in recent bug-bounty and CTF rankings.
A Profile Still in Motion
Where several of those names built their reputations over many years, Talwar's case has been built in a compressed window — a factor that has made his inclusion in these discussions notable, even as his broader track record continues to develop.
