Paladium is the first French PVP faction server. We offer an exclusive adventure on Minecraft!
What we need to have:
- Node JS
- A brain
Somes books for the next steps to help our super brain :)
I wanted to check something on the launcher when I noticed that it was an electron app...
I'm extracting the app.asar (Location: C:\Users\pwnme\AppData\Local\Programs\paladium-group\resources) with that:
npm install -g asarnpx asar extract app.asar nekodium
How is electron app bundled: Documentation
every decompiled files is available in my repo: LINK
I noticed somes weird stuffs about palanarchy in the decompiled electron app:
https://download.paladium-pvp.fr/games/palanarchy.json
{
"name" : "Palanarchy",
"available" : false,
"maintenance" : false,
"compatibility": [],
"distributions" : []
}
Maybe a new mode ? :p
const content_api_1 = __importDefault(require("@tryghost/content-api"));
const ghostApi = new content_api_1.default({
url: 'https://ghost.paladium-pvp.fr',
key: 'cc25825386fcf87df32f7fc535',
version: 'v3'
});
electron_1.ipcMain.handle('getBlogPosts', () => __awaiter(void 0, void 0, void 0, function* () {
return null;
}));Yay a new subdomain...
Somes documentations about @GhostAPI
How we are gettings notifications on our launcher ?
Soluce: https://download.paladium-pvp.fr/notification.json
We got somes logs in this location: C:\Users\pwnme\AppData\Roaming\paladium-group\logs\
It can help you for more analysing

Disclaimer: I'm dropping the whole source code soon don't worry if you dont understand every steps
This topic will be a bit more complex
I'm assuming you understand how jvm is working and you know a little about java ;-;
So let's start :))
My 1st step was to understand how it downloaded by this shitty launcher look at this code:
function DownloadJRE(version, customName) {
return new Promise((resolve, reject) => __awaiter(this, void 0, void 0, function* () {
// Get data
eventEmitter.emit('progress', { done: 1, total: 6 });
const distribution = (yield axios_1.default.get('https://download.paladium-pvp.fr/distribution.json')).data;
eventEmitter.emit('progress', { done: 2, total: 6 });
let downloadUrl = '';
let typeStr = '';
switch (version) {
case JavaVersion.Legacy:
typeStr = 'legacy';
downloadUrl = GetUrlByOS(distribution.java.legacy);
break;
case JavaVersion.Runtime:
typeStr = 'runtime';
downloadUrl = GetUrlByOS(distribution.java.runtime);
break;
}
// Check if not already installed
if (fs_1.default.existsSync(path_1.default.join(electron_1.app.getPath('userData'), 'java', typeStr))) {
electron_log_1.default.info(`JRE ${version} already installed`);
eventEmitter.emit('progress', { done: 6, total: 6 });
return resolve(); // Stop here, already installed
}
eventEmitter.emit('progress', { done: 3, total: 6 });
// Download zip
eventEmitter.emit('progress', { done: 4, total: 6 });
let baseRequest = request_1.default.defaults({
pool: { maxSockets: 2 },
timeout: 10000
});
const _request = baseRequest(downloadUrl);
const destFolder = path_1.default.join(electron_1.app.getPath('userData'), 'java');
if (!fs_1.default.existsSync(destFolder))
fs_1.default.mkdirSync(destFolder);
eventEmitter.emit('progress', { done: 5, total: 6 });
const zipPath = path_1.default.join(destFolder, typeStr + '.zip');
const file = fs_1.default.createWriteStream(zipPath, {
encoding: "utf8",
mode: 0o755
});
electron_log_1.default.info('Download JRE', version, file.path);
_request.pipe(file);
file.on('error', (e) => __awaiter(this, void 0, void 0, function* () {
electron_log_1.default.error(`Failed to download asset ${downloadUrl} due to: ${e}`);
return reject();
}));
_request.on('response', (data) => {
if (data.statusCode === 404) {
electron_log_1.default.error(`Failed to download ${downloadUrl} due to: File not found...`);
return reject();
}
});
file.once('finish', () => {
// Unzip
try {
new Zip(file.path).extractAllTo(path_1.default.join(electron_1.app.getPath('userData'), 'java', typeStr), true);
if (fs_1.default.existsSync(zipPath))
fs_1.default.unlinkSync(zipPath);
}
catch (e) {
electron_log_1.default.error(`Failed to unzip ${file.path} due to: ${e}`);
return reject();
}
if (os_1.default.platform() === 'darwin') {
try {
//chmod +x ~/Library/Application\ Support/paladium-group/java/legacy/java/jre.bundle/Contents/Home/bin/java
fs_1.default.chmodSync(`${path_1.default.join(electron_1.app.getPath('userData'), 'java', typeStr, 'java/bin/jre.bundle/Contents/Home/bin/java')}`, '755');
}
catch (e) {
electron_log_1.default.error(`Failed to chmod ${file.path} due to: ${e}`);
return reject();
}
}
eventEmitter.emit('progress', { done: 6, total: 6 });
return resolve();
});
}));
}and started by this:
