Fake GTA 6 Download Sites Are Emptying Saved Passwords

24.08.2026 4 min 6

The hype around Grand Theft Auto 6 has turned into a password-stealing trap. Days after a GTA 6 leak began spreading on 18 August, scammers stood up fake "GTA 6 demo" and download sites, and the Play Now button hands you an infostealer instead of a game. Security firm Malwarebytes traced the campaign to lookalike domains such as gta6demo[.]asia, gta6demo[.]eu, gta6demo[.]us and rockstar-gta-6[.]com. Click download and you get gta6_installer.exe, a file of just 1.1 MB, impossibly small for a real game and a dead giveaway that something is wrong.

How the trap works

The installer is Vidar, an infostealer sold as a service to criminals. It does not need to crack your browser's encryption. Instead it quietly launches your own Chrome, Edge, Firefox, Brave, Opera or Vivaldi in headless mode, so the browser itself unlocks its saved data and hands it over. The first sample was spotted on 19 August, one day after the leak, riding the wave of people searching for an early look at the game.

What Vidar steals

Once it runs, it sweeps up far more than a game key would need:

  • Saved passwords and logins from up to 19 browsers.
  • Session cookies, which let an attacker step into your accounts without the password and even past two-factor login.
  • Browsing and download history and autofill data, including addresses and card hints.
  • Email and other apps. It also targets the Thunderbird mail client, Perplexity's Comet browser and credentials saved by FTP clients.
  • Crypto and gaming accounts. Wallet data and tokens for services like Steam and Discord are prime targets.

To stay hidden, Vidar does not hard-code its control servers. It reads them from ordinary-looking profiles on Telegram, Pinterest and Steam, so the traffic blends in with normal services.

How to protect yourself

  1. There is no public GTA 6 demo. Any site offering a "demo" or early download is fake. The game comes only from Rockstar and official stores.
  2. Check the file size. A modern AAA game is tens of gigabytes. A 1 MB "installer" is malware, not a game.
  3. Do not trust search ads or mirrors. Malicious pages buy their way to the top and copy Rockstar's artwork, sometimes generated with AI.
  4. If you already ran it, act fast. From a different, clean device, change your important passwords, then sign out of active sessions everywhere and turn on two-factor authentication.
  5. Watch your accounts. Check email, crypto and gaming accounts for new logins, changed recovery details or unfamiliar devices.
Important: because Vidar grabs session cookies, simply changing your password is not enough. An attacker with a live cookie stays logged in until you sign out of all sessions on each account. Do that step, and revoke access for anything you do not recognise.
Is there actually a GTA 6 demo to download?
No. There is no public demo or early build. Anything advertised as a "GTA 6 demo", leaked build or free download is a lure. The game will be released through Rockstar and official stores only.
Would a VPN have protected me?
No. A VPN encrypts your connection, but here you download and run the file yourself, so the malware is already on your device. A VPN does not stop a program you install. What helps is not running unknown files and keeping security software on.
I already installed it. What should I do first?
Treat every saved password as compromised. From a clean device change your passwords, sign out of all active sessions, enable two-factor authentication, and check bank, crypto and email accounts. Run a full malware scan on the infected machine before using it again.
How do I spot the fake sites?
Look for lookalike domains (gta6demo and similar), a tiny download that "installs instantly", pushy Play Now buttons, and any request to disable your antivirus. When in doubt, go straight to the official Rockstar Games site rather than a search result.
