A seized device from the Kirana Mart case yielded a 64 KB firmware dump. Most of it is random noise, but someone hid readable text fragments inside, numbered like FRAG01, FRAG02, and so on.
You are given firmware.bin. Your job: pull the readable strings out of the binary, collect every fragment, sort them by their numbers, and join the pieces in order. Wrap the joined text in the flag format and you have the flag.
On Linux the strings command does exactly this job: it prints every run of readable characters in a file. Try strings firmware.bin and look for the FRAG pieces. Analysts use this technique on real firmware, malware samples, and memory dumps, because programs cannot hide their text completely.
