Libbitcoin 的 Mersenne Twister 事故：加密货币漏洞暴露了对真正随机性的需求

深入探讨 Libbitcoin Explorer 漏洞、其对 Mersenne Twister 算法的依赖，以及有关加密安全随机性的重要经验教训。

In the ever-evolving world of cryptocurrency, security vulnerabilities are a constant threat. Recently, a significant flaw in the Libbitcoin Explorer (bx) library sent ripples through the crypto community, exposing approximately 120,000 Bitcoin (BTC) private keys. The culprit? A predictable random number generation algorithm: the Mersenne Twister-32. Let's unpack this juicy bit of drama, shall we?

在不断发展的加密货币世界中，安全漏洞是一个持续的威胁。最近，Libbitcoin Explorer (bx) 库中的一个重大缺陷在加密社区引起了轩然大波，泄露了大约 120,000 个比特币 (BTC) 私钥。罪魁祸首？可预测的随机数生成算法：Mersenne Twister-32。让我们来解开这个有趣的戏剧，好吗？

The Mersenne Twister-32: Not So Random After All

Mersenne Twister-32：毕竟不是那么随机

At the heart of the Libbitcoin vulnerability lies the Mersenne Twister-32, a pseudorandom number generator (PRNG) seeded with system time. While perfectly acceptable for generating your character's stats in a video game, its deterministic nature makes it a terrible choice for cryptographic purposes. By seeding the algorithm with system time, private key generation became predictable, allowing attackers to brute-force keys faster than you can say 'decentralized finance.'

Libbitcoin 漏洞的核心在于 Mersenne Twister-32，这是一个以系统时间为种子的伪随机数生成器 (PRNG)。虽然在视频游戏中生成角色的统计数据完全可以接受，但其确定性本质使其成为加密目的的糟糕选择。通过在算法中植入系统时间，私钥的生成变得可预测，从而使攻击者能够以比“去中心化金融”更快的速度暴力破解密钥。

Impact and Fallout: Wallets at Risk

影响和后果：钱包面临风险

The vulnerability had far-reaching consequences, affecting several wallets that relied on the Libbitcoin Explorer 3.x library, including versions of Trust Wallet Extension and Core. Users of these wallets faced the very real risk of private key compromise, leading to the loss of funds. In fact, at least $900,000 worth of cryptocurrency across multiple blockchains vanished into thin air. Ouch!

该漏洞产生了深远的影响，影响了多个依赖 Libbitcoin Explorer 3.x 库的钱包，包括 Trust Wallet Extension 和 Core 的版本。这些钱包的用户面临着私钥泄露的真实风险，导致资金损失。事实上，多个区块链上至少价值 90 万美元的加密货币消失得无影无踪。哎哟!

Law Enforcement: Unexpected Exploiters?

执法：意外的剥削者？

Here's a twist: law enforcement agencies were among the first to exploit the vulnerability, using it to recover approximately 120,000 BTC linked to criminal investigations. Valued at billions, this recovery effort highlights the double-edged nature of cryptographic flaws. It's like finding a glitch in the Matrix – good for some, not so good for others.

这里有一个转折点：执法机构是最先利用该漏洞的机构之一，利用它追回了与刑事调查相关的约 120,000 比特币。这项价值数十亿美元的恢复工作凸显了加密缺陷的双刃性质。这就像在黑客帝国中发现一个小故障——对某些人有利，但对另一些人则不太好。

'Milk Sad': A Quirky Code Name

“Milk Sad”：一个古怪的代号

Adding a touch of the absurd, the vulnerability was nicknamed ‘Milk Sad’ due to the first two words of the seed phrase generated by the flawed randomization process. It's a slightly melancholy moniker for a serious security issue, but hey, it's memorable!

更荒唐的是，由于有缺陷的随机化过程生成的种子短语的前两个单词，该漏洞被昵称为“Milk Sad”。对于严重的安全问题来说，这是一个略带忧郁的绰号，但是，嘿，它令人难忘！

The Importance of True Randomness: Lessons Learned

真正随机性的重要性：经验教训

This incident serves as a stark reminder of the critical role randomness plays in cryptographic systems. To mitigate such risks, the crypto community must prioritize rigorous security audits and adopt best practices for wallet development. Hardware wallets with Secure Element (SE) chips and True Random Number Generators (TRNG) are your friends. Choose wallets with proven security records, stay vigilant about software updates, and avoid wallets using pseudorandom seeding. Got it?

这一事件清楚地提醒我们随机性在密码系统中发挥的关键作用。为了减轻此类风险，加密货币社区必须优先考虑严格的安全审核，并采用钱包开发的最佳实践。带有安全元件 (SE) 芯片和真随机数生成器 (TRNG) 的硬件钱包是您的朋友。选择具有经过验证的安全记录的钱包，对软件更新保持警惕，并避免使用伪随机种子的钱包。知道了？

Looking Ahead: A More Secure Crypto Future

展望未来：更安全的加密货币未来

The Libbitcoin vulnerability underscores the need for rigorous cryptographic standards and thorough security audits in the cryptocurrency space. Developers must prioritize secure practices, while users should remain informed and vigilant. By learning from incidents like this, we can build a more secure and resilient ecosystem.

Libbitcoin 漏洞强调了加密货币领域需要严格的加密标准和彻底的安全审核。开发人员必须优先考虑安全实践，而用户则应保持知情和警惕。通过从此类事件中吸取教训，我们可以建立一个更安全、更有弹性的生态系统。

So, there you have it. The Libbitcoin Explorer vulnerability, rooted in the Mersenne Twister-32 algorithm, exposed critical weaknesses in cryptographic practices. It's a cautionary tale, sure, but also an opportunity to learn and grow. Stay safe out there, crypto enthusiasts, and remember: true randomness is your ally!

所以，你就知道了。 Libbitcoin Explorer 漏洞源于 Mersenne Twister-32 算法，暴露了加密实践中的关键弱点。当然，这是一个警示故事，但也是一个学习和成长的机会。加密货币爱好者，请保持安全，并记住：真正的随机性是您的盟友！
