以太坊，智能合約和NPM惡意軟件：加密威脅的新時代

攻擊者正在利用以太坊智能合約掩蓋惡意軟件，這標誌著針對加密貨幣空間的網絡威脅的複雜演變。

Yo, crypto enthusiasts and security aficionados! Things are getting wild in the digital frontier. The latest buzz? Ethereum smart contracts are being weaponized to hide npm malware. Buckle up; it's a bumpy ride.

喲，加密愛好者和安全愛好者！在數字邊界，事情變得越來越瘋狂。最新的嗡嗡聲？以太坊智能合約被武器化以隱藏NPM惡意軟件。扣這是一個顛簸的旅程。

Smart Contracts: Not Just for DeFi Anymore

智能合約：不僅僅是為了defi

Remember when smart contracts were all about decentralized finance and revolutionary applications? Well, bad actors have found a new use for them: concealing malicious commands. ReversingLabs recently blew the whistle on a scheme where attackers were using Ethereum smart contracts to mask command-and-control (C2) server addresses. Instead of relying on traditional infrastructure, these sneaky coders are embedding URLs within the blockchain itself. Talk about hiding in plain sight!

還記得智能合約何時與分散的金融和革命性應用有關？好吧，壞演員為他們找到了新的用途：隱藏惡意命令。 ReversingLabs最近在一個方案上吹響了哨子，攻擊者正在使用以太坊智能合約來掩蓋命令和控制（C2）服務器地址。這些偷偷摸摸的編碼器不依賴傳統的基礎設施，而是將URL嵌入區塊鏈本身中。談論隱藏在視線中！

The lowdown? Packages like colortoolsv2 and mimelib2 on npm looked harmless but were secretly pulling instructions from these smart contracts. Once activated, they would download second-stage malware. As Lucija Valentić from ReversingLabs pointed out, hosting malicious URLs on Ethereum contracts is a novel tactic, signaling a rapid evolution in how attackers are evading security scans.

低點？ NPM上的Colortoolsv2和Mimelib2等包裝看起來無害，但秘密地從這些智能合約中提取了說明。激活後，他們將下載第二階段惡意軟件。正如ReversingLabs所指出的LucijaValentić所指出的那樣，在以太坊合同上託管惡意URL是一種新穎的策略，這表明攻擊者如何逃避安全掃描的迅速發展。

The Social Engineering Twist

社會工程扭曲

But wait, there's more! This isn't just about clever code; it's also about social engineering. These malicious packages were part of a larger campaign involving fake cryptocurrency trading bots on GitHub. Think fabricated commits, bogus maintainer accounts, and shiny documentation—all designed to lure unsuspecting developers. It’s like a digital mirage, making the malicious dependencies seem legit upon superficial review.

但是等等，還有更多！這不僅僅是聰明的代碼；這也與社會工程有關。這些惡意套餐是涉及Github上的假加密貨幣交易機器人的大型運動的一部分。思考捏造的提交，虛假的維護者帳戶和閃亮的文檔，旨在吸引毫無戒心的開發人員。這就像一個數字海市rage樓，使惡意依賴性在膚淺的評論中似乎是合法的。

A Growing Trend

增長的趨勢

This isn't an isolated incident. In 2024 alone, there have been numerous crypto-related malicious campaigns across open-source repositories. From the Lazarus Group using Ethereum contracts to spread malware to fake Solana trading bots stealing wallet credentials, the trend is clear: crypto developer tools and open-source code are prime targets.

這不是一個孤立的事件。僅在2024年，開源存儲庫就有許多與加密相關的惡意運動。從使用以太坊合同的Lazarus集團來擴展惡意軟件到偽造的索拉納交易機器人竊取錢包證書，趨勢很明顯：加密開發人員工具和開源代碼是主要目標。

While Ethereum isn't the only blockchain affected, the use of smart contracts to host malicious commands represents a significant escalation. It's like the digital equivalent of hiding a needle in a haystack, only the haystack is a public, decentralized ledger.

儘管以太坊並不是唯一受影響的區塊鏈，但使用智能合約來託管惡意命令代表了一個重大升級。就像將針頭藏在乾草堆裡的數字等效物一樣，只有乾草堆是一個公共，分散的分類帳。

Why This Matters

為什麼這很重要

This trend highlights the importance of vigilance and robust security practices in the Web3 space. Trusting code based solely on metrics like commit numbers and stars is no longer enough. Dependency verification needs to be based on code, artifacts, and network indicators. As ReversingLabs aptly puts it, trust is math.

這種趨勢強調了Web3領域的警惕和強大安全慣例的重要性。僅基於諸如提交數字和星星之類的指標的信任代碼已經不夠了。依賴性驗證需要基於代碼，工件和網絡指標。正如ReversingLabs恰當地說的那樣，信任是數學。

Personal Take: The Cat-and-Mouse Game Continues

個人拍攝：貓和鼠遊戲繼續

Look, the reality is that attackers will always seek new ways to bypass defenses. The use of Ethereum smart contracts to conceal malware commands is just the latest evolution in this ongoing cat-and-mouse game. It underscores the need for continuous monitoring, proactive threat hunting, and a healthy dose of skepticism when evaluating open-source code.

看，現實是，攻擊者將始終尋求繞過防禦的新方法。使用以太坊智能合約掩蓋惡意軟件命令只是這款正在進行的貓和鼠標遊戲中的最新演變。在評估開源代碼時，它強調了對持續監測，主動威脅狩獵以及健康劑量的懷疑的必要性。

It's a bit of a buzzkill, but necessary. I mean, nobody wants their ETH stack drained by some cleverly disguised malware, right?

這有點像嗡嗡聲，但有必要。我的意思是，沒有人希望他們的ETH堆棧被一些巧妙偽裝的惡意軟件耗盡，對嗎？

Final Thoughts

最後的想法

So, what’s the takeaway? Stay sharp, folks. Keep your security tools updated, verify your dependencies, and remember that in the world of crypto, trust but verify is more than just a mantra—it's a necessity. The bad guys are getting smarter, and we need to be one step ahead. And who knows, maybe this heightened awareness will lead to even more robust security measures in the long run. Until then, stay safe and keep those private keys locked down!

那麼，收穫是什麼？伙計們，保持敏銳。保持安全工具的更新，驗證您的依賴關係，並記住，在加密貨幣世界中，信任，但驗證不僅僅是一種咒語，這是必要的。壞人變得更聰明，我們需要領先一步。誰知道，從長遠來看，這種提高的意識將導致更加強大的安全措施。在此之前，請保持安全，並將這些私鑰鎖定！
