+# Coherence Check
+
+### Description - So we're up to date, we've moved away from using s*nity check. Here's your flag.
+
+
+Initially, this challenge may seem super simple, type out the flag you get in the image below.
+
+![Coherence Check](src/coherencerarctf.png)
+
+Sure, this will work and give you the flag of `rarctf{Welcome_To_RaRCTF!}`, however, in design of an interesting Coherence Check, I decided to go Down The Rabbit Hole, and add an extra easter egg never seen before in the land of Capture the Flag Coherence Checks - Steganography.
+
+I decided to skip the 3 common pillars of CTF Steganography - Binwalk, Steghide and Strings. The next thing that I thought of was metadata, so I decided to create some.
+
+For those with access to a command line, `exiftool` is great for metadata related problems. (can just be installed with `sudo apt install exiftool` for those with the apt package manager.)
+
+Simply running `exiftool [filename]` will bring us something interesting, as shown below.
+```

+```
+Most of this is irrelevant, but the author (me!) left a note in the description of the metadata, stating ` if you see this, DM jammy#0402 on discord secret_stego for a special role!` If you DMd jammy#0402, you would have received the Rabbithole Enthusiast role on the RaRCTF discord. Congrats to the below people for actually finding this:

+A simple discord challenge, you need to verify with the reaction bot, then run `!flag` in the spam discord channel.
+
+### Alternative solve
+
+[Rarmony](pwn/Rarmony), our CTF chat platform challenge, also had its own version of the discord flag, in the `general` channel. To get this flag, follow the below steps:

+After careful looking, we see a message from Tony stating:

+`in order to fully finish our discord migration, i've decided to repost the discord flag of rarctf{wh3n_4r3_w3-m0v1ng_b4ck_t0-IRC?_29ff18a15e}`
+
+This flag matches up from what you would get from running !flag in the spam channel.
