For this challenge, we are told that the flag is hidden on a post on LinkedIn. Lucky for us, LinkedIn has a search function, allowing us to directly search "riftCTF{" and find all posts containing the flag.


Result: We find a post by a page called Ciphercell containing the flag.

Link: https://www.linkedin.com/posts/ciphercell_ciphercell-cybersecurity-activity-6633997672254660608-tVEH

Flag: riftCTF{W3lc0me_t0_c1ph3rcell}

Note: Post has been edited after the challenge and the flag is unavailable now.
