ARRS terminal

 (Automated Radio Relay Service) is a webpage made by the developers of Escape from Tarkov for the release of the game.

Description
This a webpage appearing like a terminal. The inscription "Automated Radio Relay Service" and "NODE 14-4 KORD" can be seen. For the moment the terminal doesn't respond anything when you try to interact with the little box at the bottom. It is probable it will be reactivated later.



The name "ARRS" can also be seen on a screenshot published by the developers about the Hideout.





The ARRS terminal was connected to riddles also made by the developers of Battlestate Games. The riddles were connected to pieces of the lore of the game and the ones who achieved to get to the end of the riddle earned key for the game.

Step 1 : "QRCODE"
When you click on "tell me more" button, the following QR Code appear : After scanning it show " vjku ku pqv eyuc" which is a Caesar Code with a shift of 3 :

this is not cswa

"cswa" is actually a reference to "Contract Wars", a game from Absuloft in which some developers of Battlestate Games worked.

Step 2 : "TIMERCODE"
In 2015 a mysterious site has been discovered. It is : http://www.countdowntoreveal.com/

A light with a countdown can be seen. Also a code can be seen on the page and found in the code source of the page. The code is : "N5TYJJETNWRXJ6KBNAYYFJEGPOSXD4EG" and on 7 October 2015, "Escape From Tarkov" posted this image on Facebook : The text contain a clue to decipher the code. The clue is "CD_CES25_B32". "CES25" indicate to decrypt the code with a Ceasar Code with a shift of 25

M5SXIIDSMVQWI6JAMZXXEIDFONRWC4DF

Then "B32" indicate to decode the obtained "text" from BASE 32 to Text.

An image posted on 8 October 2015 help to decode this binary code. "(...) with his 32 troops. With a thought in his mind, he took 10 steps, enough to make light shine brighter. Then he looked again at his 32 man(...)" is actually a hint telling that we must use the BASE32 code.

The first part is in BASE32.

JNCVSX2OJ5PTAXY→KEY_NO_0_

This is a clue that indicate to remove all the three characters a zero from the second part of the previous code.

Step 1 : "LOOK IN THE DARK"
On 9 October this image was uploaded on the Facebook Page of "Escape From Tarkov". We can read " Look in the dark " on it.

On 10 October 2015 this Image was uploaded on Facebook with the inscription : "MRC_HINT UPLOADED". This image is actually an image of a computer the Wikipedia page of alpha bending. Alpha bending is linked to the transparency of an image and this is a hint for the next image.

When the transparency of the previous image is augmented we can see the inscription "S__R". It can be filled with a "P" and "Q" to obtain "SPQR" the initialism of the phrase linked to the ancient Roman Republic.

This is a link to the site : http://www.countdowntoreveal.com/spqr/

We can read the following text.

...There is YzM4 eyes out there, 38 to be ZXJyb, who 3JfbG make an error 9nLn in a while, i R4dA== judge them...

It contain a BASE64 code :

Step 2 : Combining the RAR files
It contain two times the same BASE32 code which decipher to ".dcm".

4 RAR files are needed to obtain an image. They have to be opened together, with WinRAR for example. The following is the obtained JPEG image and it is called "4hacvH6wkbZlh53c.png". We can see the city of Tarkov, "12:43:2027" and "NODE 14-4 KORD" the same inscription as seen on the ARRS terminal page.

Part 4 : "KNOWTHETRUTH12_ALLSEEINGEYE STARTED"
On 15 October 2015 this message was posted on the VKontakt group of Escape From Tarkov with an image.

KNOWTHETRUTH12_ALLSEEINGEYE STARTED

It means that all the cameras are now online.

On 27 February 2016, the user "TarkovEscaper" on Reddit, "Escape From Tarkov" on Facebook posted the same message.

''Attention! Attention!''

We've intercepted the following message

01001010 01011010 01010011 01011000 01001111 01001001 01000100 01010101 01001101 01010110 01011010 01000111 00110010 00110010 01001100 01001111 01001101 01000110 01010111 01000011 01000001 01011001 01001100 01000100 01001101 01001110 01010011 01011000 01000111 00110100 01011001 01001110 01000010 01001010 01000011 01011000 01001101 01011010 00110011 01000110 01001110 01011010 01000001 01010101 01010111 01000100 01001001 01001011 01001110 01001110 00110011 01010111 01010101 01001110 01000010 01010100 01001101 01011001 01011010 01001000 01001111

(It is a quest to get one free copy of EFT limited edition, only for one winner

You will get your prize in about 48 hours after finishing quest)"

The solution of the riddle was later posted both on Reddit and Facebook on 28 February 2016.

''One of the Tarkov mysteries solved! Congratulations to winner, who will get free digital copy of EFT Limited edition in couple days! You can try to decode the rest of codes yourself, if you still haven't, but you are not going to get any prize for that.''

For those who want to know all of the steps, here it is ''Thanks for participation! This is not last mystery of Tarkov.''
 * 1) Binary code that was announced with quest - the easiest part
 * 2) After that you get Base32 code which have login and password to ARRS terminal
 * 3) In the profile you can find 3 notes about dark deeds of Evgenue A.K. and last note have hidden ASCII85 encrypted parts
 * 4) It gives us an image, a screenshot from email of this Evgenue, which have hidden Morze code
 * 5) Morze gives us an audio file, from which we find out about new service available at /TARBANK and it also have Morze code
 * 6) You can use EvgenAK login/pass for the Tarbank page and you see that it have safe with password field
 * 7) Morze from step 5 have anogramm for "furious winds" which is login and password for ARRS and it have last bits of riddle
 * 8) Profile have 4 notes, 3 of which got parts of password to safe and the last one is the order of those notes to get password together.

Step 1 : Binary code to BASE 32
The binary code is a BASE 32.

JZSXOIDUMVZG22LOMFWCAYLDMNSXG4YNBJCXMZ3FNZAUWDIKNN3WUNBTMYZHO

Step 2 : Base 32 to Text and connection to the ARRS terminal
The Base 32 is decrypted to ASCII text and give this :

New terminal access

EvgenAK

kwj43f2w

So the username is "EvgenAK" and the password "kwj43f2w".

Then the username and the password must be used into the ARRS terminal.

Step 3 : Decryption of the 3 notes of the "EvgenAK" profile
You can find 3 notes on the profile page :

Note 203
DATE:: 23.08.2012 ::

The last one contain some ASCII85 code:



After decryption it give that:

ORUGK4TPNVQW4NTTORSXA427/otzkxi000cy.pvm

The first part is encoded in BASE 32 :

theroman6steps_

The "theroman6steps" part is a clue to decipher the second part "otzkxi000cy.pvm". It refers to Ceasar Code with a shift of 6 steps. So it give

interc000ws.jpg

It give us a link a link to an image :

http://countdowntoreveal.com/interc000ws.jpg

Step 4 : Image with Morse Code
This is the obtained image :

It contain a Morse Code which is :

wlkdjsnwed.mp3

It lead to the MP3 file located here : http://countdowntoreveal.com/wlkdjsnwed.mp3

Step 5 : Audio File analysis and Morse Code
The audio file instruct about the site http://countdowntoreveal.com/tarbank (this site is unavailable) and contain a Morse Code which is :

P_RUSIUOF_ P_NDISW_P_RUSIUOF_P_NDISW

Step 6 : Tarbank login
The use of the username "EvgenAK" and the password "kwj43f2w" is required to enter the site. Once entered a new password is required.

Step 7 : ARRS terminal login
A new username and password must be used in the ARRS terminal. They are given by the Step 5 Morse Code. It is a anagram of "Furious Winds".

P_FURIOUS_P_WINDS_FURIOUS_P_WINDS

Step 8 : Decryption of the 4 Notes of the "Furious Winds" profile
The "profile page" contain 4 notes :

Note 101
shift14_oSRlo3phoyDiKJV0PCa5APslYPU

Note 102
01110000 01100001 01110011 01110011 01110111 01101111 01110010 01100100 01110000 01100001 01110010 01110100 00001101 00001010 00110101 00111001 00111001 00110011 00110000 00111001

Note 103
33 35 30 37 31 31 34 31 20 33 34 30 36 32 31 36 32 20 33 33 36 37 33 35 36 33 20 33 34 36 36 30 35 36 30 20 30 33 32 30 35 30 36 35 20 31 35 30 33 32 30 36 37 20 31 35 30 33 31 34

Note 104
50 49 51

The first part of the note 101 "shift14" give a clue to the Caesar Code with a shift of 14. The second part decipher to this:

cGFzc3dvcmRwYXJ0DQo5ODgzMDI

This a BASE 64 code which decipher to this :

passwordpart

988302

The note 102 is a binary code.

passwordpart

599309

The note 103 are ASCII character in Hexadecimal which give :

trapdrowssap

544743

Inverted it give :

passwordpart

347445

The note 104 contain 3 ASCII characters in hexadecimal who refers to there counterparty in Text.

2 1 3

It give the order to assemble the 3 part and give the password "599309988302347445" to redeem the key which is already activated.

Riddle : "Strange Signal"
On 27 June 2016 Escape From Tarkov posted this message on Facebook :

We've intercepted strange signal, that translates into following text.

In the "uzfqdoqbfqp.txt" file we can find the word "archive" which lead to the site http://countdowntoreveal.com/archive (This is site is currently unavaible). A page with a username already completed with "ceasar" and a password can be seen.

Step 5 : Decryption of the password and Login
The numbers at the end of each RAR file are the number of space to count between the characters from the beginning of each linked TXT file. The order is given by the linked MP3 file.

Following the order the password is "24089460354063017".

The password must then be entered on the site found before : http://countdowntoreveal.com/archive/
