舊合約，大問題：Truebit 代幣遭受大規模黑客流失和以太幣盜竊

Truebit 的 TRU 代幣在價值 2600 萬美元的以太幣被盜後崩潰，暴露了遺留智能合約漏洞。這對 DeFi 世界來說是一個鮮明的提醒。

Another Day, Another Digital Dollar Disappears

又一天，又一個數字美元消失了

Well, folks, grab a cuppa and settle in. It seems the wild, wired world of decentralized finance just served up another stark reminder of its volatile nature. This time, the spotlight’s on Truebit, an Ethereum-based project that watched its TRU token plummet nearly 99.9% faster than a hot dog vendor closing shop on a rainy Tuesday. The culprit? A sophisticated hacker, who, with a flair for the dramatic, drained approximately 8,535 Ether – a cool $26.6 million – from the protocol’s reserves. It’s a story as old as time, or at least as old as five-year-old smart contracts.

好吧，伙計們，喝杯茶，安頓下來吧。去中心化金融的狂野、有線世界似乎再次鮮明地提醒人們其不穩定的本質。這次，焦點集中在 Truebit，這是一個基於以太坊的項目，該項目的 TRU 代幣暴跌速度比熱狗供應商在下雨的星期二關門的速度快了近 99.9%。罪魁禍首？一位經驗豐富的黑客，憑藉戲劇性的天賦，從協議的儲備中耗盡了大約 8,535 個以太幣——相當於 2660 萬美元。這是一個與時間一樣古老的故事，或者至少與五年前的智能合約一樣古老。

The Glitch in the Old Machine: How the Ether Vanished

舊機器的故障：以太幣是如何消失的

According to the digital detectives at Lookonchain and independent researchers like Weilin Li, this wasn’t some cutting-edge, never-before-seen trick. No, this was a classic case of an antique vulnerability. The attacker exploited a flaw in an *older* smart contract, deployed roughly half a decade ago. Imagine that: code from 2021 coming back to bite you in 2026. This particular old-timer had a minting function that, under just the right (or wrong) conditions, would essentially give away TRU tokens for free. Our resourceful hacker then repeatedly bought these 'free' tokens and immediately sold them back into the protocol’s reserve, steadily siphoning off Ether with each transaction. They even reportedly paid a small 'builder bribe' to ensure their transactions got VIP treatment, like getting the best table at a crowded restaurant.

根據 Lookonchain 的數字偵探和李偉林等獨立研究人員的說法，這不是什麼尖端的、前所未見的伎倆。不，這是一個古老漏洞的典型案例。攻擊者利用了大約五年前部署的“較舊”智能合約中的缺陷。想像一下：2021 年的代碼會在 2026 年回來咬你。這個特殊的老前輩有一個鑄造功能，在正確（或錯誤）的條件下，基本上會免費贈送 TRU 代幣。然後，我們足智多謀的黑客反复購買這些“免費”代幣，並立即將它們賣回協議的儲備中，在每筆交易中穩步吸走以太幣。據報導，他們甚至向“建築商行賄”，以確保他們的交易得到 VIP 待遇，比如在擁擠的餐廳獲得最好的餐桌。

Market Mayhem and a Muted Response

市場混亂和反應冷淡

As word spread, the TRU token’s price did a swan dive, leaving many investors with holdings worth less than a subway token. Liquidity evaporated, and panic selling ensued. Truebit, for its part, acknowledged the

隨著消息傳開，TRU 代幣的價格大幅跳水，許多投資者持有的代幣價值還低於地鐵代幣。流動性蒸發，恐慌性拋售隨之而來。 Truebit 則承認
