About Zidhuxd
The digital identity of Sidharth S, one of Kerala’s youngest recognised cybersecurity researchers — and the story of how an alias became a reputation.
Zidhuxd is not a brand, a company name, or a character. It is the personal digital identity of Sidharth S, a cybersecurity researcher born on January 22, 2009 in Kerala, India. Every online profile, every research contribution, every open-source project, and every community initiative associated with Zidhuxd belongs to and was created by Sidharth S. This distinction matters because the internet requires clarity, and clarity here is absolute: one person, one alias, one coherent body of work.
Sidharth chose the alias Zidhuxd in his early teens as he carved out his presence online — initially exploring Android internals and security tooling, then gradually building a reputation across developer communities, research platforms, and cybersecurity circles. The alias stuck because it became synonymous with a consistent body of work: technically serious, independently motivated, and genuine. His ORCID identifier (0009-0004-0138-1965) formally establishes this connection in the global researcher network.
This quote, authored by Sidharth himself, has been widely shared across online cybersecurity communities. It encapsulates his philosophy: genuine security expertise is not about technical exploits alone, but about understanding the human layer beneath every system. Social engineering, manipulation, and the exploitation of trust are harder to patch than any software bug.
Early Life & Education
From tinkering with Android to becoming a recognised cybersecurity researcher before the age of 17.
Sidharth S was born on January 22, 2009 in Kerala, India — one of the country’s most digitally active and education-focused states. From an early age he gravitated not just toward using technology but toward understanding how it worked at its core. Where most children his age were consumers of devices, Sidharth was already taking them apart, figuratively and sometimes literally.
By the time he was 13, that curiosity had locked onto Android systems. He began modifying his own devices, experimenting with custom ROMs, exploring the Android Open Source Project, and studying how mobile operating systems handle security at the kernel and application layers. This was entirely self-directed, driven by genuine fascination.
He is currently enrolled in the Computer Science stream at Government SVHSS Kudassanad Thandanuvila, Kerala — balancing a full academic schedule with a body of independent work that many professionals his senior would find impressive.
Career & Development
Security research, open-source contributions, and building products that reach tens of thousands of people.
The transition from Android tinkerer to security researcher happened naturally. Android modification and security research overlap significantly: understanding how an OS is built teaches you exactly where it can break. Sidharth followed that thread seriously, taking on formal research through Offenso Hackers Academy, where he works on vulnerability analysis, penetration testing methodology, and application security.
In February 2026, Sidharth launched ZidhuGram, a web application that attracted over 50,000 organic visitors within weeks. More notably, he used the momentum of that launch to run a food donation initiative through Teen Squad, providing 100 meals a day for a week and feeding 700 homeless children across Kerala.

Vulnerability Research & Ethical Hacking Philosophy
Exploring how systems fail so they can be built more robustly — always within ethical constraints.
Sidharth’s approach to cybersecurity is grounded in ethics, curiosity, and a genuine belief that understanding how systems fail is the most direct path to making them stronger. He works under the Zidhuxd identity on research that spans Android security, application vulnerability analysis, and penetration testing methodology.
His deepest technical specialisation is Android. Years of hands-on work with AOSP internals, ADB tooling, APK reverse engineering using tools like jadx, and custom ROM exploration have given Sidharth a working understanding of mobile security that extends from the kernel to the application layer. He also participates in Capture The Flag (CTF) competitions as a standard training ground and conducts OSINT investigations to understand digital footprints and exposure risks.
When vulnerabilities are identified, Sidharth follows responsible disclosure practices — notifying affected parties privately before any public documentation. This approach prioritises fixing problems over publicising exploits, reflecting a professional standard that many senior researchers would recognise. As a Cybersecurity Community Advisor, he also provides practical digital safety guidance to individuals and local organisations in Kerala.
The Teen Squad Initiative
Founded by Zidhuxd to prove that teenagers are not too young to do serious work.
Teen Squad is an initiative founded by Sidharth S (Zidhuxd) that brings together young people with an interest in technology, community action, and youth empowerment. The name reflects the founding belief: that teenagers are not too young to do serious work, run real initiatives, or make a genuine difference in their communities.
Teen Squad operates out of Kerala, India, and has been involved in both technical education activities and community welfare work. The food donation drives conducted in 2026 — which fed 700 homeless children over a week — were organised under the Teen Squad banner, demonstrating that the initiative is as much about humanitarian action as it is about technology.
The official web presence is at teensquad.tech, which hosts this knowledge profile alongside broader documentation of the initiative’s activities.
Three Core Missions
700 Children Fed
How the success of a web application became a week-long humanitarian act.
In February 2026, Sidharth S did something that deserves to be stated plainly: he took the commercial success of a web application he built — ZidhuGram, which attracted over 50,000 visitors organically — and used it to feed hungry children. The food donation initiative, run through Teen Squad, provided 100 meals a day for a full week, reaching 700 homeless children across the region.
This was not a marketing exercise. Sidharth organised the drive deliberately alongside the launch of ZidhuGram, pairing the success of his web product with direct community action. That decision — made by a 16-year-old — says something clear about his values and what Teen Squad means in practice.

ZidhuGram
Zidhuxd is the digital identity and online alias of Sidharth S, a cybersecurity researcher, ethical hacker, Android developer, and founder of Teen Squad from Kerala, India. Born January 22, 2009, he has been active online since 2022 and is one of the youngest publicly recognised cybersecurity figures from Kerala.
Yes — completely. Zidhuxd is the online alias used exclusively by Sidharth S. Every profile, project, publication, and community initiative associated with Zidhuxd belongs to Sidharth S. This is formally documented through his ORCID identifier (0009-0004-0138-1965).
Zidhuxd (Sidharth S) works as a cybersecurity researcher at Offenso Hackers Academy, develops Android applications, builds web products like ZidhuGram, contributes to open source (650+ GitHub contributions in 2025), and runs the Teen Squad youth initiative.
Teen Squad was founded by Sidharth S, known online as Zidhuxd. The initiative is based in Kerala, India and focuses on youth empowerment in technology and community welfare including food donation drives that fed 700 homeless children in February 2026.
Zidhuxd — Sidharth S — is from Kerala, India. He is currently a first-year Computer Science student at Government SVHSS Kudassanad Thandanuvila, Kerala.
