TIN_LRU6 a single video published on June 16, 2015.

Similar to the First Wave videos it is encoded and reversed, with a simple Letter to Number cipher.

"YOU BE SEE ACHE EYE" is a homophone clue; when read aloud, it pronounces the spelling of UBCHI— a double transposition cipher.

In the video, at 0:02, the lower left corner flashes a scrambled string of text, can be seen appearing for less than one second. /_yo1utF.tEsuI/subbhG:jteZpV/ This is a Youtube URL encrypted using UBCHI. It was quickly decrypted using a bruteforce attack; thereby, bypassing the need for the (still undetermined) keyword — whose columnar key is: 10 4 5 1 6 7 2 8 9 3.

The decrypted URL provided a link to the unlisted, since removed, video: THE_PEN.

This video has been archived, and the reason for its removal, is discussed is in the relevant article.

TIN_LRU6's Audio
"Her fate is yours..."

Using the same process as previous videos. The audio was recomposed to reveal a hidden audio: "Her fate is yours..." Throwing down the gauntlet to solvers, in a race against time; this was a reference to the captive woman seen in the decrypted url: THE_PEN.

At the time, anons failed to make sufficient progress to save the woman. Her fate remains unknown.

Considerations for Potential Solvers
As Ubchi requires a keyword to be decoded properly, by bruteforcing the encryption, we may have missed an important clue. The keyword, if known, could provide a clue to aid further decryption. Yet, the only thing we know about this key is its disposition, and that it likely consists of a single word.

It's columnar disposition is: 10 4 5 1 6 7 2 8 9 3 Some words that apply this disposition are: voodooisti, winepresse, thicknesse, thicknessi Columnar disposition is determined by valuating the keyword alphabetically, then converting the letters to numbers. Thus, ABC = 123. ACB = 132. CODE becomes 1423. Judging by the nonsense words generated above, it is likely the word is reversed; therefore the true disposition of the keyword is likely: 3 9 8 2 7 6 1 5 4 10 There is no word (using this dictionary) that matches with these keys [program].
