Hyrdroponics IoT: InfluxDB Pipeline + Grafana Dashboard

As a member of the IoT4Ag group at UPenn's mLAB, I spearheaded all the data pipelines: the backend InfluxDB database and frontend Grafana dashboard. My work directly supported the lab's objective: develop computer vision capabilities for precision agriculture. Here are some highlights I accomplished:

• Facilitated cleaner data processing by writing a sensor class template to connect physical sensors to InfluxDB loggers and prepping camera data for InfluxDB and Grafana

• Automated data-loading in Python to easily send JSON payloads from CSV files to InfluxDB database

• Configured InfluxDB and Grafana containers to run on Docker on a Raspberry Pi

• Developed website and control board web app using Django/Jinja and Bootstrap frameworks

• Presented weekly literature review summaries at lab reading group

ROP Gadgets + Buffer Overflows

I used GDB to disassemble target C programs and inject malicious shellcode. My attacks exploited buffer and integer overflows. Some of my exploits used ROP and gadgets to bypass non-executable stack protection and ASLR. In other attacks, I added customized shellcode to set the UID to zero and obtain a root shell.

This project was completed for CIS-551 (Computer and Network Security). I am not allowed to post my repo publicly due to Penn's academic integrity policies, but I am more than happy to discuss my work.

Mini Dynamic and Static Analyzers (LLVM Instrumentation)

I am currently taking Software Analysis (CIS-547) and successfully completed 6 labs thus far. Most recently, I instrumented an LLVM pass to implement static dataflow analysis in C++ and Python for given test programs. I have also instrumented LLVM passes to measure code coverage for a mini dynamic analyzer. Other labs I completed involved augmenting a delta debugger and statistical debugger.

LC-4 Complete Disassembler and Partial Assembler

I built a complete disassembler for Penn's LC-4. It takes in a raw binary file and outputs the full assembly code. My disassembler covers the entire LC-4 instruction set, including directives.

I implemented a partial assembler for Penn's LC-4 that handles a subset of LC-4 instructions. My assembler takes an LC-4 assembly file and produces an executable binary file for the source code. It ignores all comments and accepts directives for .CODE, .ADDR, and .DATA. 

​

The disassembler was completed as my final project's optional extra-credit for CIT-593. The assembler was also completed for CIT-593 and includes optional extra-credit portions. I am not allowed to post my repo publicly due to Penn's academic integrity policies, but I am more than happy to discuss my work.
