Introduction
Question: Can you invoke help flags for a tool or binary? This program has extraordinarily helpful information…
Files: warm
Overview & Solving
Approach: After downloading the file running the command
file warm
shows it as an executable file.
When we try to run using
./warm
It gives error. One of the reason might be that it does not have execution permission. To give permission enter
chmod +x warm
running again gives
Hello user! Pass me a -h to learn what I can do!
Finally running
./warm -h
returns the flag
Flag: picoCTF{b1scu1ts_4nd_gr4vy_6635aa47}
Another unconventional method involves utilizing the ‘strings’ command to extract all text strings from a file.
Next, these strings can be saved into a text file. Following this, the ‘gedit’ find option can be employed to search for the flag using the filter string ‘picoCTF{‘ since flags consistently commence with this sequence.
Thinking outside the box can occasionally streamline processes, yet success isn’t guaranteed in every instance.
