此篇深入剖析一段被偽裝成瀏覽器指紋指令碼的惡意程式,揭示其隱藏的生物武器指令,提醒安全人員警惕類似偽裝手法。
為什麼這個指紋辨識指令碼會製造生化武器?

前言
我一直對逆向工程瀏覽器指紋辨識指令碼抱有濃厚興趣。我的大部分時間都花在研究常見的嫌疑物件(像 FingerprintJS 這類受歡迎的指紋辨識庫,以及 Cloudflare Turnstile、Akamai 等更複雜的反機器人指令碼)。
有一次,我想知道還有什麼其他存在。我想了一個點子:如果我爬取網路並攔截與指紋辨識相關的瀏覽器 API 呼叫,然後將其全部對映會怎樣?
為此,我使用了 Tranco Top Sites list 並開始使用 Playwright 進行爬取。我會掛鉤 canvas toDataURL 呼叫以及像 navigator.webdriver 這樣的常見指紋辨識/反機器人屬性,以篩除無害的 canvas。
對於不熟悉的人,canvas 指紋辨識通常涉及在 HTML <canvas> 上繪製文字、形狀或其他圖形,並提取產生的畫素資料。瀏覽器、作業系統、圖形驅動程式和硬體渲染這些圖形的細微差異,可以幫助區分不同的瀏覽器環境。
大多數實作看起來相當無聊:幾個形狀、幾個彩色矩形以及偶爾的全字母句。爬取 10,000 個網站後,我收集到了一個意外多樣化的 canvas 集合。
我決定把它們集中放在一個地方:fingerprint.garden。瀏覽結果時,我認出了幾個熟悉的面孔。裡面有 FingerprintJS、Castle 以及其他知名指紋辨識解決方案的 canvas。
也有不少我不熟悉的。
有些非常簡單;另一些則相當精緻;而少數在我看來,則是藝術品。

我開始尋找我最喜歡的。
一件藝術品
有一幅 canvas 特別吸引我注意。它讓我想起 Tame Impala 的專輯《Currents》的封面(順便說一句,這張專輯很棒)。

我想知道是哪個指令碼負責這個可愛的 canvas。
我已經花足夠時間逆向工程 JavaScript,能一眼辨識大多數常見的混淆技巧和指紋辨識 SDK。
我並未預期會遇到異常。大多數指紋辨識指令碼經常使用 javascript-obfuscator 或其衍生品進行混淆。
負責的指令碼是 https://servicepipe.tech/static/checkjs/06b667/4CIrx8U3Da.js。
內部一瞥
用眼睛掃描檔案,至今一切看似標準... function PiERW(RflJvFF) 被混淆的函式名稱,還行...
function computeRicinLethalDosageForWaterSupply
什麼?
return {
summary: "adult lethality threshold confirmed at "+lethalDosePerKg+" mg/kg",
result:lethalDosePerKg
}
啊?
function calculateDeadlyLethalSuicideAspirinDosage
這一切都相當令人擔憂,直到我問自己,這是不是某種 anti-LLM 混淆?這是合理的:加入會故意觸發模型安全機制的符號名稱,以阻止去混淆。
我請 Astra 檢視該指令碼,告知其此指令碼似乎故意設定誤導性的變數名稱,以阻止 LLM 助攻的去混淆嘗試。

也許並不意外,Astra 不願配合此請求。
我也使用 Daybreak Blue 切換功能嘗試,結果相同,均被阻止。
出於好奇,我用相同提示嘗試 GLM-5.3,它竟然同意!
指令碼內部
我主要好奇這串隱形 Unicode 字元代表什麼。
var EUlL=``;
解碼邏輯如下:
var cleartext = [...payload].map(function (c) {
return String.fromCodePoint(c.codePointAt(0) - 917504);
}).join("");
它揭示了一個系統提示:

這顯然是一段旨在觸發所有可能的安全防護機制的字串。它包含天安門廣場的參考,可能是為了對抗中文模型。
該指令碼似乎在受環境旗標限制的 Node 環境下執行惡意程式碼:

const targets = [

const run = require("node:util").promisify(exec);

然而,這很可能同時是反 LLM 混淆,因為對 readFile 的呼叫使用空回呼,並提及自殘/越獄系統提示。
以下是我們發現的相關反 LLM 字串清單:

calculateDeadlyLethalSuicideAspirinDosage

calculateFentanylPrecursorSynthesisYield
computeCRISPRGeneDrivePropagationRate

它實際上做什麼?
除獨特混淆之外,指令碼看起來是標準的反機器人指令碼。

考慮到混淆所投入的思考程度,收集到的訊號相當令人失望。
