UIUCTF 2021

UIUCTF is an annual Capture the Flag competition run by undergraduate students at the University of Illinois at Urbana-Champaign (UIUC).

This was my first time playing the annual UIUCTF, and I must say it was a really great experience. Social Engineering Experts ended in 18th place, out of 658 scoring teams.

I tried my hand at a variety of challenges across categories such as forensics and web exploitation.

It was a tough 48 hours, but the satisfaction from solving each challenge was definitely worth it! Glad that Angmar and I pushed through, solving two of the challenges way past midnight and a few hours before the CTF ended.

I also won a $100 bounty for the first blood on Pwnies Please, a machine learning challenge that required solvers to generate adversarial examples to fool an image classification model.
