The Synacktiv summer challenge is back!
The Synacktiv summer challenge is back!
Edit: we had an issue with the binary prior to 2019-06-19 09:15, please download it again.
Dana has just finished a nice brain teaser for his friend Alonzo. It is a Linux executable that accepts a single argument, and displays a string. Can you craft an input that makes the program print Alonzo!?
Once you have found a valid input, validate the challenge by sending your solution to hacktheplanet@synacktiv.com.
Contestants will be ranked by time of submission. The prizes are:
- The winner gets a ChipWhisperer Lite 32-bit Basic Board
- The second to answer gets a HummingBoard Edge
- And finally, the third wins a Diva IOT board
Happy reversing!
The Synacktiv Team
P.S.: Of course, it might be possible to exploit a bug in the validation logic and take a shortcut here. Even though they will not qualify for a prize, do not hesitate sending us these solutions!
