I've been watching the Marble Hornets videos on YouTube (basically, an independent film series about a group of kids chased by the "Slender Man"), and in this video I saw something interesting. Normally, the videos have "Entry #" whatever as the title, but in this one (supposedly from the "bad guys", I guess), it's a repeating, glitching pattern of the following four series of characters:

R0IH0T{}T010G
RWIT}H00{10G
}IHWRGT00{10
1IHR{WGT0}00

Also, @EvanTeitelman found apparently the full stream of text, if that's helpful. Here's the pastebin he made.

I don't recognize this as any kind of encoding or cipher, so I was hoping the actual security experts might be able to enlighten me if there is one, or if it's actually just random nonsense. I'm always interested in learning something new from the pros!

The reasons I don't think it's random nonsense are:

  • The same four sequences are repeated; if it were random, I would expect lots of random strings.
  • It uses the same general alphabet (set of characters). (Actually, that just made me think -- maybe a simple substitution cipher?)
  • And, most importantly, the binary at the end of the "bad guy's video" is an actual binary representation of a string, not random nonsense. Translated into ASCII, the binary comes out to thetrees.

All of this makes me think that the data is indeed intentional rather than random noise.

The only thing I see in it is that each line has a set of brackets, a power of 10, and the letters for the word "RIGHT", combined with either a "T" or a "W". That's all I've got.

I found more of the cipher text (pastebin.com/3RAkA7jP) on a forum. –  Evan Teitelman Jun 25 '13 at 4:06
    
@EvanTeitelman Wow, awesome! I was trying to go slow as I could, frame by frame, but that's hard to do on YouTube. Thanks! –  Jeff Gohlke Jun 25 '13 at 4:08
    
No problem. This question is more appropriate for the cryptography stack exchange though. –  Evan Teitelman Jun 25 '13 at 4:16
    
Try to use CrypTool to analyze that. –  Marek Jun 25 '13 at 4:17

@EvanTeitelman My apologies. I didn't even know that Beta existed. If admins would like me to delete this and repost there, just let me know. I've seen questions about ciphers on here before, and so thought it would be appropriate. –  Jeff Gohlke Jun 25 '13 at 4:17
