Balancer被黑客攻擊,損失超過一億美元!

Balancer審計受到關注,因超過1億美元的漏洞事件

隨著去中心化交易所及自動化市場製造商Balancer發生成功的漏洞事件,超過1億美元的數字資產被盜,許多加密貨幣交易者正在尋求答案。

在週一的一則X推文中,Balancer更新了用戶,表示此次事件“僅限於V2可組合穩定池,並不影響Balancer V3或其他Balancer池”。

該平台補充說,它已經接受了頂尖公司的廣泛審計,並且長期以來都有漏洞獎勵計劃以激勵獨立審計人,這讓人質疑漏洞是如何發生的。

“Balancer經歷了超過10次的審計,”TAC區塊鏈的開發者關係負責人Suhail Kakar在X上表示。“該金庫被三家不同的公司審計過,仍然被黑客攻擊,損失達到1.1億美元。這個領域需要接受‘由X審計’幾乎沒有意義。代碼很難,去中心化金融更難。”

根據GitHub上提供的Balancer V2審計清單,四家不同的安全公司——OpenZeppelin、Trail of Bits、Certora和ABDK——對該平台的智能合約進行了11次審計,其中最新的一次是在2022年9月由Trail of Bits進行的。

Cointelegraph聯繫了OpenZeppelin以獲取評論,但在發稿時尚未收到回覆。Trail of Bits的發言人則拒絕對此次漏洞事件發表評論,表示“在確定根本原因之前,所有Balancer的分叉都不安全”。

此次漏洞事件的報導早在週一就出現,導致超過1.16億美元的質押以太幣(包括StakeWise質押ETH、包裝以太幣(WETH)和Lido的wstETH)被轉移到一個新創建的錢包。Nansen的一位研究分析師告訴Cointelegraph,Balancer事件可能源於智能合約問題,存在“故障的訪問檢查,允許攻擊者發送命令提取資金”。

項目提供20%白帽獎金以回收資金

在週一的一筆區塊鏈交易中,Balancer團隊向攻擊者發出通知,提供高達20%被盜資金的白帽獎金,如果在48小時內全額歸還。

“如果你選擇不合作,我們已經聘請了獨立的區塊鏈取證專家,並積極與多個執法機構和監管合作夥伴合作,”Balancer表示。

截至發稿時,該項目尚未宣布有關獎金或漏洞的其他更新。

這次事件再次強調了去中心化金融(DeFi)領域的安全性問題。即使經過多次審計,漏洞仍然可能存在,這對投資者和用戶來說是一個警示。未來,如何提高智能合約的安全性和透明度,將是整個行業需要深思的課題。

Ultra-realistic cinematic shot of a lone secret agent sprinting across connected rooftops in a European old town.
Wind whipping his jacket as he leaps between buildings.
A helicopter hovers low behind him, its spotlight cutting through drifting dust.
Camera angle: low-angle chase shot.
Mood: high-stakes, relentless pursuit. add mickey mouse Base Setup
keep 100 percent facial information adherence of the attached image and turn her into a lone night hiker standing in the shallow river at the mouth of the canyon, captured as a live action photograph or movie still, not an illustration or CGI render, with an alluring, confident, quietly sexy mood.

Shot and Camera
Three quarter body shot from slightly low height on the riverbank, placing her on the left third while the water leads into the dark canyon and the star filled sky dominates the top of the frame, preserving the original wide vertical composition.

Identity and Pose
She has a slim athletic build, natural proportions, medium length loose hair, and lightly tanned skin, 8k Photorealistic and hyper realistic. She stands barefoot in the water with one leg forward, hips relaxed, wearing a fitted cropped technical top and separate high waisted trail shorts with an open lightweight jacket slipping off one shoulder, one hand loosely holding a headlamp at her side and the other brushing hair from her face as she looks up at the stars.

Lighting and Environment
Keep the soft starlight and faint glow from the distant horizon, giving a gentle rim on her shoulders and hair while a subtle fill from the reflected sky reveals her features. The canyon walls, river reflections, pebbled shore, and dense star field stay exactly like the reference, with small ripples around her feet grounding her in the water.

Masking and Constraints
Change only by adding the subject and her outfit, keep lighting, perspective, white balance, canyon geometry, and river reflections the same, with realistic scale, body proportions, and clear contact between feet and water surface. Change only the requested element and keep lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same, and absolutely avoid added text, painterly or toon styling, CGI look, blown highlights, banding, plastic skin, overly tidy backgrounds, or floating feet while requiring consistent perspective, consistent white balance, subtle film like grain, and physically correct contact shadows and reflections.
