This paper presents a comprehensive cryptanalytic review of the critical vulnerability  CVE-2023-39910 , codenamed  "Milk Sad ," discovered in the widely used  Libbitcoin Explorer utility versions 3.0.0–3.6.0. The fundamental flaw lies in the use of a cryptographically insecure Mersenne Twister-32 (MT19937)  pseudorandom number generator  initialized by the system time, which catastrophically limits the entropy space to  32 bits  instead of the required 256 bits. The paper thoroughly…

This paper analyzes cryptographic vulnerabilities discovered in modern cryptographic key management infrastructure, with a particular focus on critical flaws in the architecture of hardware security modules (HSMs) when handling elliptic curve private keys. The study focuses on a class of attacks that exploit insufficiently isolated RAM management in certified cryptographic devices. In the modern Bitcoin cryptographic ecosystem,…

This article examines the evolution of security threats in the cryptocurrency storage space, focusing on modern methods for compromising private keys and seed phrases, which secure digital wallets. The modern cryptocurrency ecosystem faces a growing threat of cyberattacks aimed at compromising private keys and seed phrases, which are the foundation of digital wallet security. The complexity and…

This article examines the systemic cryptographic security threats posed by the Phoenix Rowhammer attack (CVE-2025-6202), which can extract private keys from DDR5 RAM through hardware-level bit manipulation. In recent years, the dynamic development of cryptocurrency technologies has led to an increased dependence of digital asset ecosystems on hardware and microchip components that store and process cryptographic data.…

In this article, we will look at the cryptographic attack of digital signature forgery (Digital Signature Forgery Attack), its consequences pose a threat to the security of transactions in the Bitcoin network, since digital signatures confirm the ownership and authorization of cryptocurrency transfers. We will consider examples of the impact of such attacks on Bitcoin based on…

This paper discusses how an attacker can introduce a hidden list of vulnerabilities through module updates, which can lead to compromise of ESP32 devices and gaining unauthorized access to private keys, affecting billions of devices using this microcontroller. One of the key issues is the CVE-2025-27840 vulnerability discovered in the ESP32 architecture. To ensure security for the Bitcoin network,…

Many crypto experts are asking: Will the cryptocurrency industry be able to withstand the new technological revolution? This article will discuss modern methods of protecting financial transactions and the Internet based on cryptography, which may be powerless against a sufficiently powerful quantum computer, and whether cryptocurrencies, whose market is estimated at hundreds of billions of dollars, are…
