2017¶

Capture the Flag - Mindreader

2017 was a tough one. Nonetheless, big thanks to for hosting an event.

Challenge:

Can you read my mind?

No hints.

Challenge:

If you hear enough, you may hear the whispers of a key...
If you see app.py well enough, you will notice the UI sucks...

No hints.

Challenge: The website isn't really me much, but you can still get the admin password, right?

Hint: Sometimes an error message can be just as useful

Challenge:

You found a suspicious USB drive in a jar of pickles. It contains this file

$ file freeThePickles.class
freeThePickles.class: compiled Java class data, version 52.0 (Java 1.8)

Hint: Is there a way to get the source of the program?

Had a blast participating with a few local DC416 folks in the 2017 picoCTF!

Challenge:

Can you help me find the data in this littleschoolbus.bmp?

Hint: Look at least significant bit (LSB) encoding!!
