Second wave

**TODO LIST**

Second wave
On 14 June, 2015; 5 more encoded videos are uploaded in mixed order to tinman's channel; with addition of TIN_BODY, which is discussed in the next article.

Similar to the First Wave, the Second Wave videos contain a series of numbers— this time, a row of 10 digits.

However, they are no longer encoded with a basic Letter to Number cipher. As in all numbered videos the 0 is not enumerated. The Second Wave and TIN_BODY numbers are all encircled, strongly suggesting a connection between numbers.

To date, this connection, and their encryptions have not been solved.

TIN B04
1101021212

TIN C03
0544518051

TIN H02
4010012021

TIN I01
1497590839

TIN U05
1589951805 As with the previous videos, and using the same process, a hidden audio was uncovered: "ARE YOU A FOOL OR SINNER?" This same audio was duplicated across all 5 videos. They can heard individually below:
 * TIN I01


 * TIN H02


 * TIN C03


 * TIN B04


 * TIN U05

Titles & Playlist
The titles, once arranged, form the word UBCHI in reverse.

Übchi is name given by French cryptanalysts to a double transposition cipher used by the German military in WWI.

Übchi decryption was later employed with success, in a bruteforce attack on an encrypted url found in TIN_LRU6

A simple Ubchi decryption program can be found online here.

As with the First Wave, the Second Wave videos were placed in a separate play-list

This time titled: 031918012513191420011202 Decoded this reads: CSRAYMSNTALB To date, this has not been decrypted.

Considerations for Potential Solvers
Ubchi is a double transposition cipher — that means it has been encrypted twice with 2 keys. If the order of the playlist 43215 points to one key, the second is still undetermined. Other points of note are: the absence of the number 6''; this could merely indicate the plaintext contains no F-06, P-16, or Z-26. ''

Also worth nothing is the near balance of base numbers, 0,1,2 (28) to stem numbers, 3-9, (22). If the base numbers were coupled with the stem numbers, there would remain only 3 (6) base letters — which means there are only 3 possible instances of A(01), B (02), J(10), K(11), L(12), T(20), U(21) or V(22) in the entire plaintext.

The potential solver is advised to investigate in depth —particularly the videos possible connection to TIN_BODY1—and to draw their own conclusions.

TODO

 * Find out the relation to TIN_BODY1;
 * Find the meaning of the playlist's name;
 * Find out the meaning of the code inside the second batch of videos;
 * Find out the meaning of the missing segments from Kennedy's speech.
