Unraring the rar file, we optain a corrupted png
After some time of playing around, DutChen18 found out that after removing the png, you’ll get a RIFF file, or just find where RIFF pops up in the png file and remove everything before RIFF, then we get an audio file.
Opening the riff file with audacity, we immediately see binary data at the start of the file
After painfully writing out the binary data, we get the flag
