Knowing the source (e.g., HackTheBox, TryHackMe, or a specific university lab) will help me find the exact flag location for you.

Search all extracted strings for common flag formats (e.g., FLAG... , CTF... , or MBFSE... ): grep -rE "MBFSE|FLAG|CTF" . Use code with caution. Copied to clipboard

Once extracted, challenges named like this usually contain one of the following:

: Run file MBFSE30.rar to confirm it is indeed a RAR archive.

If the archive is password-protected, look for the "Key" in these common locations:

: If it contains a .img or .vmdk , mount it or use Autopsy to find deleted files.

: If there is a .pcap , open it in Wireshark and filter by http or dns to find the flag.
