Libbitcoin 的 Mersenne Twister 事故：加密貨幣漏洞暴露了對真正隨機性的需求

深入探討 Libbitcoin Explorer 漏洞、其對 Mersenne Twister 算法的依賴，以及有關加密安全隨機性的重要經驗教訓。

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?

在不斷發展的加密貨幣世界中，安全漏洞是一個持續的威脅。最近，Libbitcoin Explorer (bx) 庫中的一個重大缺陷在加密社區引起了軒然大波，洩露了大約 120,000 個比特幣 (BTC) 私鑰。罪魁禍首？可預測的隨機數生成算法：Mersenne Twister-32。讓我們來解開這個有趣的戲劇，好嗎？

The Mersenne Twister-32: Not So Random After All

Mersenne Twister-32：畢竟不是那麼隨機

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 漏洞的核心在於 Mersenne Twister-32，這是一個以系統時間為種子的偽隨機數生成器 (PRNG)。雖然在視頻遊戲中生成角色的統計數據完全可以接受，但其確定性本質使其成為加密目的的糟糕選擇。通過在算法中植入系統時間，私鑰的生成變得可預測，從而使攻擊者能夠以比“去中心化金融”更快的速度暴力破解密鑰。

Impact and Fallout: Wallets at Risk

影響和後果：錢包面臨風險

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!

該漏洞產生了深遠的影響，影響了多個依賴 Libbitcoin Explorer 3.x 庫的錢包，包括 Trust Wallet Extension 和 Core 的版本。這些錢包的用戶面臨著私鑰洩露的真實風險，導致資金損失。事實上，多個區塊鏈上至少價值 90 萬美元的加密貨幣消失得無影無踪。哎喲!

Law Enforcement: Unexpected Exploiters?

執法：意外的剝削者？

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.

這裡有一個轉折點：執法機構是最先利用該漏洞的機構之一，利用它追回了與刑事調查相關的約 120,000 比特幣。這項價值數十億美元的恢復工作凸顯了加密缺陷的雙刃性質。這就像在黑客帝國中發現一個小故障——對某些人有利，但對另一些人則不太好。

'Milk Sad': A Quirky Code Name

“Milk Sad”：一個古怪的代號

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，由於有缺陷的隨機化過程生成的種子短語的前兩個單詞，該漏洞被暱稱為“Milk Sad”。對於嚴重的安全問題來說，這是一個略帶憂鬱的綽號，但是，嘿，它令人難忘！

The Importance of True Randomness: Lessons Learned

真正隨機性的重要性：經驗教訓

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?

這一事件清楚地提醒我們隨機性在密碼系統中發揮的關鍵作用。為了減輕此類風險，加密貨幣社區必須優先考慮嚴格的安全審核，並採用錢包開發的最佳實踐。帶有安全元件 (SE) 芯片和真隨機數生成器 (TRNG) 的硬件錢包是您的朋友。選擇具有經過驗證的安全記錄的錢包，對軟件更新保持警惕，並避免使用偽隨機種子的錢包。知道了？

Looking Ahead: A More Secure Crypto Future

展望未來：更安全的加密貨幣未來

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 漏洞強調了加密貨幣領域需要嚴格的加密標準和徹底的安全審核。開發人員必須優先考慮安全實踐，而用戶則應保持知情和警惕。通過從此類事件中吸取教訓，我們可以建立一個更安全、更有彈性的生態系統。

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 漏洞源於 Mersenne Twister-32 算法，暴露了加密實踐中的關鍵弱點。當然，這是一個警示故事，但也是一個學習和成長的機會。加密貨幣愛好者，請保持安全，並記住：真正的隨機性是您的盟友！
