NeoCryptoKey is an innovative software specialized in the cryptanalysis of the bitcoin-php/bitwasp libraries, widely used in PHP projects related to Bitcoin. In recent years, critical vulnerabilities have been discovered in this library that significantly weaken the security of private keys and, consequently, users’ funds. Based on a thorough analysis of these vulnerabilities, developers created NeoCryptoKey — a tool that allows the recovery of lost or forgotten Bitcoin wallets by exploiting these errors and vulnerabilities.
Key vulnerabilities include:
In 2020, a vulnerability related to the deterministic key generation algorithm BIP32 was discovered. This flaw allowed private keys to be calculated from public ones, posing a direct threat to the security of users’ cryptocurrency assets.
In 2022, a vulnerability was found in the implementation of the ECDSA digital signature algorithm used for signing Bitcoin transactions. This vulnerability allowed extracting the private key from signed transactions, which is especially dangerous for large accounts.
Additionally, systemic issues affecting transaction security and network interaction were identified — double-spending transaction verification errors, lack of SSL/TLS checks, CSRF vulnerabilities, and fee calculation errors.
NeoCryptoKey uses these explored vulnerabilities to recover lost private keys and passwords by implementing cryptanalytic attack algorithms such as:
- Exploiting defects in BIP32 key generation algorithms;
- Analyzing ECDSA transaction signatures to extract keys;
- Attacking vulnerabilities in transaction processing and network interaction.
The practical application of NeoCryptoKey significantly expands the possibilities for restoring access to Bitcoin wallets, especially in cases where the seed phrase is lost, wallet.dat files are corrupted, or passwords are forgotten. The tool uses CPU/GPU computational resources and multithreading methods to increase the speed of finding the correct keys.
Users are strongly advised to avoid using vulnerable versions of bitcoin-php/bitwasp, regularly update dependencies, employ multi-factor authentication, and store funds in hardware wallets. In case of access loss, specialized tools like NeoCryptoKey or professional assistance become effective solutions.
NeoCryptoKey demonstrates an innovative approach to solving the problem of Bitcoin asset loss, forecasting the growing demand for cryptanalytic recovery methods amid the continuous increase in cryptocurrency value and their widespread use. Special attention to security and timely use of advanced tools can significantly reduce the risk of fund loss in the next-generation digital economy.
NeoCryptoKey addresses the challenge of recovering lost Bitcoin wallets by leveraging identified vulnerabilities in the bitcoin-php/bitwasp library, enabling cryptanalytic attacks to recover private keys. Specifically, the program exploits:
- Errors in the deterministic BIP32 key generation algorithm discovered in 2020, allowing private keys to be derived from public data;
- Analysis of ECDSA-signed transaction signatures to extract private keys thanks to a vulnerability found in 2022;
- Attacks on weak points in transaction processing and network interaction, such as lack of verification and susceptibility to man-in-the-middle attacks.
Thanks to these methods, NeoCryptoKey can recover lost private keys and passwords even when the seed phrase is lost, wallet.dat files are damaged, or passwords forgotten. The use of cryptanalysis algorithms, CPU/GPU computing power, and multithreading enhances the efficiency of finding the correct key to access funds.
NeoCryptoKey does not merely rely on traditional recovery means but applies deep technical analysis of software implementation vulnerabilities to realistically restore access to Bitcoin wallets.
NeoCryptoKey finds lost Bitcoin wallets using the following types of vulnerabilities identified in the bitcoin-php/bitwasp library:
- Vulnerability in the deterministic BIP32 key generation algorithm that allows private keys to be derived from public data;
- Vulnerability in the implementation of the ECDSA signing algorithm that permits extraction of private keys from signed transactions;
- Lack of double-spending transaction verification;
- Errors in transaction signature code leading to key compromise;
- Lack of SSL/TLS certificate verification during network connections, allowing man-in-the-middle attacks;
- Fee calculation errors potentially causing transaction rejection or overpayment;
- CSRF vulnerabilities in web wallets enabling unauthorized transactions.
By exploiting these vulnerabilities, NeoCryptoKey employs cryptanalytic methods for recovering private keys and passwords, helping restore access to lost Bitcoin wallets.
