Discord has a search functionality that allows us to search for messages with specific filters. The
after:2023-12-31 before:2024-02-01
filter allows us to search for messages sent only in January 2024. (The challenge
and CTF was made in 2024, so we can infer that). Additionally, since we know the flag starts with csd{
, we can add
that to our query.
Our final search query is after:2023-12-31 before:2024-02-01 csd{
.
One message sparks our
interest, that includes a flag sent by the challenge author.
Flag: csd{5t0pl00klng@tm@hme$$ag3s}
