+Challenge: Sleeping Guard  
+Category: Crypto
+Author: Sophia D'Antoine
+Points: 50 
+
+Question Text: 
+Only true hackers can see the image in this magic PNG.... 
+
+Answer: 
+(flag printed in the decrypted magic.png file)
+flag{l4zy_H4CK3rs_d0nt_g3T_MAg1C_FlaG5}
+
+Organizer Description:
+    This challenge is a server which sends you a base64 encoded PNG image. The hint is given in the title to solve this. First that the encoding mechanism is a Xor and the way to decrypt is use the fact that all PNG's have the same first 12 byte headers. 
+
+To distribute:
+    sleeping_49d06c703032f66151ae07066d509c61.py  (md5sum appended)
+
+Setup:
+    Distrubute the server code after REMOVING the encryption key used in the Xor.
+    Server side run the server with the correct key in it.
+
+Hints:
+    Possible hints are look at the title for clues. All files have same magic header.
+
+Solution Script:
+    Attached is the solution script to recover the key to xor with.

+### Description
+Is kill can fix? Sign the autopsy file?
+
+### Suggested Point Value
+50
+
+### Solution
+
+`kill.pcapng` is kill. The file signature should be corrected to `0A 0D 0D 0A`... The third file's FTP-DATA starting at packet 696 contains the flag in a jpg file.

+# Watchword
+
+### Description
+Canned epic hidden snek flavored cookies have shy gorilla.
+
+### Suggested Point Value
+100
+
+### Solution
+
+The description "canned" hints toward the file having more files within it. powpow.mp4 has a png appended to it. 
+
+The description "epic hidden snek flavored" hints at the module stepic. Using stepic to write the output to a different file reveals a jpg.
+
+powpow.mp4 's properties show that the Artist is Stefan Hetzl, the Title is `aHR0cDovL3N0ZWdoaWRlLnNvdXJjZWZvcmdlLm5ldC8=`, and the file was last modified October 09, 2003 (the last update to the steghide website). This points to steghide, since the title is base64 for [steghide's website](http://steghide.sourceforge.net/). The title of the challenge is "Watchword", which is a synonym for password. Using steghide and the password "password" on the jpg reveals a text file.
+
+The text file is Base85 for the flag.
+
+### Flag
+
+`flag{We are fsociety, we are finally free, we are finally awake!}`

+(Which is actually one of the wrong submitted flags for Eric Liang's Recon challenge last year.)

+### Description
+DO WHAT YE WANT 'CAUSE A PIRATE IS FREE. YOU ARE A PIRATE!
+
+### Suggested Point Value
+200
+
+### Solution
+
+The challenge name, "YAAR HAAR FIDDLE DEE DEE" is a reference to a viral youtube video, as well as a hint. The description is just some of the lyrics of the viral song.
+The challenge is a pcap of a "conversation" created with python sockets. There 3 base 64 encoded strings, one is just a blob of 100x100 grayscale images, one is an encrypted zip file, and one is an xml file which is formatted to opencv's haar cascade format. Players must seperate out the images, load the haar cascade file with opencv and run it against the images in the file, all of this, as well as the parameters required, are alluded to in the dialog that is also in the pcap. They will also need to draw a square over the object that the haar cascade detects, so that they can successfully identify it as a "skull and crossbones", which is then the password for the encrypted zip file (without spaces, as stated in the pcap), which contains flag.txt. the dialog also helpfully states that the map (the cascade file) points to the key (the skull and crossbones) for the booty (the zip file), and also says no spaces and no capitalized letters.
+
+### Flag
+
+flag{b31Ng_4_P1r4tE_1s_4lR1GHT_w1Th_M3}
+
+### Condensed Solution
+
+extract base64 strings, decode into 3 different files
+binwalk -e the image blob
+use opencv python docs to write a haar cascade script
+identify the jollyroger and use that as the password for the zip
+cat flag.txt
