Summary


Tools

  • SHA256 Online Tool: XORBIN
  • AES Decryption: Secure text elements are typically encrypted using OpenSSL's AES cipher. Use OpenSSL.

Useful OpenSSL command structure:

openssl enc -aes-256-cbc -d -a -in <filename> -out <output_filename>

Useful OpenSSL flags:

  • -d: decrypts data
  • -a: tells OpenSSL that the encrypted data is in base64
  • -in <filename>: specifies the file to decrypt
  • -out <filename>: specifies the file to put the decrypted data in

Walkthrough

Phase 1: The Binary Matrix

URL: https://gsmg.io/puzzle

The initial image contains squares which represent bits.

  • Black/Blue = 1
  • Yellow/White = 0

It forms a 14x14 binary matrix:

0 0 1 1 0 1 0 0 1 0 1 1 0 0
1 1 1 1 0 0 1 1 1 0 1 0 1 1
1 1 0 1 1 1 0 1 0 0 1 0 0 1
0 1 1 0 1 0 0 0 0 1 1 1 0 1
0 1 1 0 0 0 1 1 0 0 0 1 1 0
1 0 0 1 1 0 0 0 1 0 0 0 1 1
1 0 0 1 1 1 0 0 0 1 0 0 0 0
1 1 1 0 0 0 0 0 0 0 1 0 0 0
0 0 0 1 1 1 0 1 1 1 1 1 0 1
1 1 1 1 1 1 0 0 1 1 0 0 0 1

0 1 0 1 1 1 0 1 0 0 0 1 1 0
0 1 1 0 1 1 0 1 1 0 1 0 1 1

Start from the upper-left square and read counterclockwise in a spiral. Convert the 8-bit groups to ASCII characters:

01100111 (103 g)
01110011 (115 s)
01101101 (109 m)
01100111 (103 g)
00101110 (46 .)
01101001 (105 i)
01101111 (111 o)
00101111 (47 /)
01110100 (116 t)

01110100 (116 t)
01100101 (101 e)
01100100 (100 d)

Resulting string: gsmg.io/theseedisplanted


Phase 2: The Seed is Planted

URL: https://gsmg.io/theseedisplanted

The Seed is Planted

The pictures refer to the song The Warning (by Logic). You can decipher this by rearranging the images: war + ning and LO + (crypto) gic.

Lyrics:

intro The warning

verse Phase one The seed is planted when opposites attract Can you dig it? It takes the physical to create the physical

Phase two The flower blossoms through what seems to be a concrete surface i.e. greed, racism, insanity, physical and social handicaps These are the things that mob the flower Red rose or black rose; no in-between

Phase 3 The Judgement If it were to fall upon you today, which flower would you be? The red rose or the black?

outro This is the warning

This webpage also contains a hidden POST form accessible via your browser's Developer Tools (F12 in Chrome).

  1. Unhide it.
  2. Enter the password: theflowerblossomsthroughwhatseemstobeaconcretesurface

Phase 3: Choice is an Illusion

URL: https://gsmg.io/choiceisanillusioncreatedbetweenthosewithpowerandthosewithoutaveryspecialdessertiwroteitmyself

Phase 2 Image

This phase's title references a quote from The Matrix Reloaded:

Merovingian: You see, there is only one constant one universal: causality - cause and effect. Morpheus: Everything begins with choice. Merovingian: No. Wrong. Choice is an illusion created between those with power and those without.

The primary password for this step's payload is causality. Hashing it yields the decryption key: SHA256(causality) = eb3efb5151e6255994711fe8f2264427ceeebf88109e1d7fad5b0a8b6d07e5bf

Decrypt the provided text (phase2.txt) in your terminal:

openssl enc -aes-256-cbc -d -a -in phase2.txt -pass pass:eb3efb5151e6255994711fe8f2264427ceeebf88109e1d7fad5b0a8b6d07e5bf

Decryption Result:

The ironic 2name of the keymakers trying to protect the current digital powers which are still in severe danger due to the keymaker's way of security by hiding, nearly unprotected, in plain sight. {eps3.4_[in one of the valleys of Phillip]runtime-error.r00., where daughters hit magic keypads} When this fails.. Crypto finally to the latin 3Moon? Tell me, 4How so mate?
# X 2 S H 4 Y 0 Q B 15 #
Q -> extend the name of a hackers' swordless fish, the I and W are below.
B -> ((BV80605001911AP)- (sqrt(-1)))^2
H -> (Answer to only this puzzle but nothing else) * -1
S -> cha' + (vagh * jav)
Ok kid, on the highway, let put it in the worst gear.

(Note: It is somewhat unclear how all equations relate, but researchers noted that S equals Klingon numbers 2+(5*6)=32 and BV80605001911AP is an Intel i5 processor model, evaluating B to (5i-i)^2 = 16i^2 = -16.)

Phase 3.1: Passwords Assembly

Using the other hints (2name, 3Moon, 4How so mate) which refer to a Thales Hardware Security Module, you must assemble a massive, 7-part password.

The Parts:

  1. causality - Established in the beginning.
  2. Safenet - From "2name" reference.
  3. Luna - From "3Moon" reference.
  4. HSM - Hardware Security Module ("4How so mate").
  5. 11110 - A reference to John F. Kennedy's Executive Order 11110 ("A ruler with a number... 5binary code" trying to rein in the Federal Reserve).
  6. 0x736B6E616220726F662074756F6C69616220646E6F63657320666F206B6E697262206E6F20726F6C6C65636E61684320393030322F6E614A2F33302073656D695420656854 - "raw data after 4 on row 1616" points to the genesis block in the source code to Bitcoin itself. (And "/(aBa, connected enf)" means keep casing and remove whitespace).
  7. B5KR/1r5B/2R5/2b1p1p1/2P1k1P1/1p2P2p/1P2P2P/3N1N2 b - - 0 1 - "A buddhist is forced to move...": A chess position reference after a move that avoids a checkmate. ("/(aBa, connected not enf)" means keep whitespace).

Concatenate all 7 parts exactly and take the SHA256 hash:

SHA256(causalitySafenetLunaHSM111100x736B6E616220726F662074756F6C69616220646E6F63657320666F206B6E697262206E6F20726F6C6C65636E61684320393030322F6E614A2F33302073656D695420656854B5KR/1r5B/2R5/2b1p1p1/2P1k1P1/1p2P2p/1P2P2P/3N1N2 b - - 0 1)
= 1a57c572caf3cf722e41f5f9cf99ffacff06728a43032dd44c481c77d2ec30d5

This hash acts as the key to decrypt phase3.txt:

openssl enc -aes-256-cbc -d -a -in phase3.txt -pass pass:1a57c572caf3cf722e41f5f9cf99ffacff06728a43032dd44c481c77d2ec30d5

Decryption Result of phase3.txt:

What if the merovingian is wrong. What instead of causality something else could be ours? Therefor, if so, the ...... is ours. The thinker's 1name behind all of that would grant you access to the next step (of humanity). Definitely look into his works might you have time. /(aa,connected enf)

I just passed a cheshire cat and I'm getting fed up with this puzzle.. It's taking forever. But, How long is forever? I don't know, but just add giveit in front of the answer and you can fall in the keyhole. /(aa,connected enf)

3.The fundamental limit to the precision with which certain pairs of physical properties are know. /(aa,connected enf)

Phase 3.2 is ciphered with aes-256-cbc base64 and a sha256 pw, yet again.
U2FsdGVkX1/u/Exb78Fl...

Phase 3.2: The Merovingian

Assemble the next password from the hints in the decrypted text above:

  1. "The thinker's 1name behind all of that..." -> Jacque Fresco ("The future is fluid... The future is ours to direct.") -> jacquefresco
  2. "I just passed a cheshire cat... How long is forever? add giveit in front..." -> Alice in Wonderland quote: "Sometimes, just one second" -> giveitjustonesecond
  3. "3.The fundamental limit to the precision..." -> heisenbergsuncertaintyprinciple

Combine these into the next password string: jacquefrescogiveitjustonesecondheisenbergsuncertaintyprinciple

Its SHA256 hash is: 250f37726d6862939f723edc4f993fde9d33c6004aab4f2203d9ee489d61ce4c

Decrypt phase3.2.txt (the Base64 payload from phase3.txt) using this hash:

openssl enc -aes-256-cbc -d -a -in phase3.2.txt -pass pass:250f37726d6862939f723edc4f993fde9d33c6004aab4f2203d9ee489d61ce4c

Decrypted Text (phase3.2.txt):

I've been waiting for you. You have many questions, and although the process has altered your consciousness, you remain irrevocably human. Ergo, some of my answers you will understand, and some of them you will not. Concordantly, while your first question may be the most pertinent, you may or may not realize it is also irrelevant.

... am I here? Wake up, you... I've designed you a beautiful strategic position. One for one, four for one.

Phase 3.2.1: Beaufort Cipher

In the decrypted text, clues:

  • "... am I here? Wake up, you..." -> From The Matrix: "The matrix has you" (replacing neo with you). So the key is THEMATRIXHASYOU.
  • "beautiful strategic position" -> Beaufort cipher.
  • "one for one, four for one" -> 1141 -> IBM EBCDIC 1141 encoding.

The symbol blob (Block 1) translated via EBCDIC 1141 yields a sequence of letters: vtkvplmepphluw... (snip)

Go to a cipher tool like CipherTools, paste the string, select Beaufort, and use the key THEMATRIXHASYOU. The translated message resembles The Architect from The Matrix:

Phase 3.2.2: VIC Cipher

The number string: 15165943121972409169171213758951813141543131412428154191312181219433121171617137149110916631213131281491109166131412199114371612126021664313711154112 Clues sentence: "A fubcd-king & oracle-queen, thingky mvps, on a sad board but as wide as the first one seen."

This references the VIC Cipher.

  • Removing repeating characters: FUBCD ORA.LE THINGKY MVPS
  • Appending the remaining letters: FUBCDORA.LETHINGKYMVPS/JQZXW

Using a VIC Cipher Decoder:

  • Alphabet: FUBCDORA.LETHINGKYMVPS.JQZXW
  • Digit 1: 1
  • Digit 2: 4
  • Input code: 1516594...

Decoding Salphaseion

The two highlighted abba sections can be decoded first. Treat a = 0 and b = 1, and interpret the resulting strings as 8-bit binary representation of ASCII characters:

  1. a b b a b b a b a b b a a a a b a b b b a b a a a b b b a a b a a b b a b a a b a b b b b a a a a b b b a a b b a b b b a b a b a b b a b b a b a b b a b b a a a b b a b a a b a b b b a a b b a b b b a b a a -> matrixsumlist
  2. a b b a a b a b a b b a b b b a a b b b a b a a a b b a a b a b a b b b a a b a -> enter

The "shabef" Encoding: We see the sequence shabef directly before English text "our first hint is your last command". In previous steps, the first command was sha256. Therefore, we infer a mapping: s=s, h=h, a=a, b=2, e=5, f=6 -> Meaning it maps purely to its alphabetical position (a=1, b=2 ... z=26) representing sha256.

The letter z seems to act as a separator to segment the character blocks:

  • Block 1: a g d a f a o a h e i e c g g c h g i c b b h c g b e h c f c o a b i c f d h h c d b b c a g b d a i o b b g b e a d e d d e
  • Block 2: c f o b f d h g d o b d g o o i i g d o c d a o o f i d h

Since letters only range from a-i and o, we translate a-i to 1-9 and o to 0:

  1. 174161018595377387932283725836301293648834223172419022725145445
  2. 36026487402470099740341006948

Treating these sequences as Base-16 integers provides corresponding hex strings, which map to ASCII text:

  1. Translates to: lastwordsbeforearchichoice
  2. Translates to: thispassword

anstoo = 1-14-19-20-15-15 (Further steps to decrypt the remaining AES blob in Salphaseion with these passwords are ongoing...)

Poem from the Creator

Roses are White but often Red.
Yellow has a number and so does Blue.
Go back to the first puzzle piece without further ado.

It might have shown you only one door, beware that the rabbits nest may contain a whole lot more.

Hush hush.

ECDSA Signatures from the Puzzle Address

The following are the ECDSA signature components extracted from spending transactions of the puzzle address 1GSMG1JC9wtdSwfwApgj2xcmJPAwx7prBe. All inputs share the same uncompressed public key.

Public Key (all inputs):

04f4d1bbd91e65e2a019566a17574e97dae908b784b388891848007e4f55d5a46
49c73d25fc5ed8fd7227cab0be4e576c0c6404db5aa546286563e4be12bf33559

Each signature consists of:

  • R, S — the two components of the ECDSA signature
  • Z — the transaction sighash (the message that was signed)
  • sighash_type — 1 = SIGHASH_ALL

Note: Having multiple signatures from the same key allows for nonce-reuse (lattice) attacks if any two R values are repeated across inputs. All R values above are distinct, but the 6 signatures together may still carry useful information for lattice-based private key recovery attempts.
