DESCRIPTION
Recently, LightSpeedCorp has been constantly having security issues in their environment. So although Luther, Sjang, and Bobby are developers, their boss Steffie decided to send them for a three-day reverse engineering training on Ghidra, a sexy new tool released by the NSA in 2019. When they came back from the training, the three of them were smiling all day to themselves about how great they were in reverse engineering even though they hardly knew anything about it. Steffie decided to pull them back to earth by giving them a day to solve a reverse engineering challenge.
Turns out, none of them could solve this reversing challenge. Can you help them before they get fired?
