Powerpoint-programing

by vishalananth

A login page in powerpoint should be good enough, right?

Files

Solution

Open the file in Microsoft Powerpoint, we tried other tools like LibreOffice and WPS Office but it did not work. Rename the file from chall.ppsx which will open in Kiosk Mode to chall.ppt which will open it in the edit mode in Powerpoint. Go to the Animations Menu and you will see only a few buttons have animations associated. You will also find the animations trigger order on the right pane, you can see that animation will correspond to a button on the keyboard. Tracing it fully gives us the flag.
