Security Cheatsheets

A collection of "cheatsheets" for popular security tools.


An Android app using JBL's Pulse 2 speakers to bring life to your party. Just pair the speaker, push the button, and start partying. When the countdown using the LEDs on the front of the speaker runs out and the song changes, take a drink.

Winner of State Farm's favorite hack, best hack on a .tech domain, and (second) best hack using Harman speakers at HackGSU 2016.
