| Repository | What it is |
|---|---|
| Vulnerability-Assessment-Case-Study | Passive security assessment of a Government of India web application. Found 6 vulnerabilities (1 Critical, 3 High, 2 Medium) using only OSINT and enumeration, with no exploitation. Disclosed through CERT-In (case CERTIn-74835826); the organization fixed all 6 issues. |
| snake-traitor-tracing | Python implementation of the traitor-tracing scheme from Joye and Lepoint (ACM DRM 2011). Each software copy is bound to a player-specific RSA key, so a leaked copy can be traced to the corresponding player. Demonstrated on a terminal Snake game with an admin page that finds the leaker. |
| air-gapped-mpls-copilot | Project Aether. Offline prototype that flags likely MPLS link failures from telemetry. It takes automatic action only when an LSTM model and a NetworkX capacity check agree; otherwise the decision goes to an operator. Tested on a simulated 7-node Containerlab L3VPN network with synthetic data: about 82% fault-classification accuracy, and all 5 simulated degradations detected before SLA breach (503 seconds early on average). |
| android-llm-server | OpenAI-compatible LLM server built with llama.cpp on an unrooted Galaxy S25 with a broken screen. Running the model on the phone's GPU (Vulkan) and 6 matched CPU cores raised prompt processing from 17.9 to 70.2 tokens/s. |
| Repository | What it is |
|---|---|
| turbojet-digital-twin | Aerothon finalist (IIT Indore with HAL). Physics-informed digital twin of a four-stage turbojet that estimates hidden component health and thrust from limited sensor data, with a 3D dashboard. |
| urban-heat-island-mitigation-simulation | Avinya finalist (IIT Guwahati). Landsat 8 and Google Earth Engine analysis of Guwahati on a 100 m grid, with a dashboard that suggests where cooling measures would help most. |
| ground-zero-mesh | Avinya (IIT Guwahati). Android app that passes SOS messages phone to phone when cell towers are down. Kotlin. |
CTFs: Dark Street (3rd/14) · Into The Void 2.0 (8th/150 qualifiers, 7th/40 finals) · L3m0nCTF (12th/120) · Backdoor (96th/602)
| Repository | What it is |
|---|---|
| ad-dmsa-privilege-escalation-lab | Lab for the BadSuccessor dMSA privilege-escalation technique in Windows Server 2025 Active Directory, built with @Hemashankar19. Lab setup is done; attack reproduction and detection rules are next. |
| latency-aware-edge-game-placement | Containerlab edge-cloud testbed running a Minecraft server under bot load, to measure where the latency formula used for edge server placement stops matching reality. Early results: each node holds about 100 players per CPU core, and latency stays flat until that point, then jumps sharply, a shape the formula cannot express. |
