In this project, I implemented attacks against a defense mechanism, named circuit breaker, that limits harmful response generation in LLMs. Circuit breaker defend against harmful prompts by fine-tuning LLMs to not generate any harmful token. I implemented embedding space attack to bypass the defense of circuit breaker and force LLMs to generate harmful responses. LLMs recognize hamrful prompts by observing the corresponsding embedding matrix for that prompt. Given a harmful prompt, I developed programs to find an embedding matrix that can trick circuit breaker tuned LLM to not consider the prompt as harmful.

A framework to automatically test efficacy of security solutions proposed for IoT systems. With this framework researchers or developers of IoT security solutions can automatically generate test-cases and evaluate efficacy of their solutions and compare them with existing similar solutions intuitively. A regular user of IoT system can use VetIoT to pin-point security issues in the system and develop security policies for that.

SEED Emulator is a python framework that emulates operations of a real world internet. I am developing a module of the emulator which emulates oeprations of the SDN. In my implementation, I am using faucet (formarly known as RYU) as SDN controller and OpenVSwitch as virtual sdn enabled switch.

Developed a Full-stack (front-end: React, Backend: Django) website with complete authentication and deployed it in AWS with apropriate scalability.

VPN client applications or built-in VPN configurators of popular OSs can leak data outside of VPN tunnel. In this project, I created a malicious wifi network. If a user connects to this malicious wifi access point, I can force user's traffic to follow a path outside of the VPN tunnel. In a more perilious scenario, this attack can be formed remotely by pairing with a dns hijacking

Built a tree based machine learning model to predict arrival status of flights arriving at SYR (Hancock Internation) airport from JFK (New York, NY), MCO (Orlando,FL), and ORD (Chicago, IL). To increase accuracy, we incorporated both historical weather data and flight arrival data from transtats. During prediction, we dynamically injected weather forcasting data to query.

Broadcom Wifi/Bluetooth combo chip is used in many smartphones and laptops including iPhones, Samsung phones, and Macbooks. In this project, I emulated the firmware of the combo chip using qemu and fuzzed the firmware with randomly generated bluetooth packets. During fuzzing I found 2 CVEs: one crashing the firmware and another creating heap corruption error.
