Challenge

Can you find the flag in file without running it? You can also find the file in /problems/strings-it_0_b76c77672f6285e3a39c188481cdff99 on the shell server.

Hint

strings

Solution

First of all, we want to make “strings” file readable, so let’s use the strings command

open terminal -> move to the folder of the file (by cd) -*> strings strings > output.txt

• strings - the strings command cast binary/executable file to human-readable string.
  • command syntax:

    strings FILENAME

added > output.txt to save the results of the command in output.txt file. now, we can open the output.txt file and see a lot of garbage, let’s do the same trick we did in grep 1(add link).

open terminal -> move to the folder of the file (by cd) -*> grep "picoCTF" file

Flag

picoCTF{5tRIng5_1T_f1527258}
