Run Me, Baby!


This one's easy, ain't it? Just run the .class file. Hope you like Java!


Trying to execute the Class file resulted in an error to to missing Groovy libraries:

$ java runme
Error: Could not find or load main class runme
Caused by: java.lang.NoClassDefFoundError: groovy/lang/Script

Luckily for me there was a Groovy JAR file included with Ghidra on my CTF-Rig.

$ java -cp /home/pingtrip/Tools/ghidra/Ghidra/Features/GhidraServer/data/yajsw-stable-12.12/lib/extended/groovy/groovy-all-2.4.11.jar:. runme
[removed the program warnings]

The flag is: he2021{isnt_17_gr00vy_baby?}

The accepted flag was, he2021{isnt_17_gr00vy_baby?}
