Fake Gemini Installer Lures Users via Google Colab

Help Net Security · Medium sophistication
Last updated August 20, 2026

Attackers tricked a user into downloading a fake “Google Gemini” Windows installer by using a Google Colab page that looked trustworthy and then redirecting to a spoofed software download site. The downloaded file delivered the Vidar infostealer, which is commonly used to steal browser-stored passwords and other sensitive data.

Key findings

  • A malicious executable posed as a Google Gemini installer and was executed on a company network in EMEA.
  • The lure relied on a trusted Google platform (Google Colab) to increase legitimacy, then redirected to a spoofed “Windows Software Hub” site.
  • The payload was a newer Go-compiled Vidar infostealer variant and activity aligned with theft of browser credentials and sensitive data.
  • The campaign included instructions to run the executable as admin and add it to antivirus exclusions.
  • Command-and-control traffic was observed to a Telegram-based infrastructure with endpoint dtm[.]kijangturbo88[.]top.

Who’s being targeted

  • Commonly targeted roles: All employees, IT, Developers, Data Science/ML teams, Security awareness trainees.
  • Affected industries: Unspecified enterprise (EMEA region).
  • Attack channels: website.
  • Impersonated: Google Gemini installer / 'Windows Software Hub' download site, Software installer documentation (README).

Awareness takeaways

  • Only install AI tools (and any software) from official vendor download pages, avoid downloads reached via search results, redirects, or file-sharing/notebook platforms.
  • Treat any installer instructions that request admin rights or antivirus exclusions as a major warning sign and escalate to IT/security.
  • Be especially cautious of AI-themed downloads and websites, attackers actively exploit interest in AI tools to trick users.

Red flags to watch for

  • Download is hosted/linked through an unexpected third-party page rather than an official vendor download site
  • Installer instructions ask to run as administrator and add an antivirus exclusion
  • Redirect chain from a 'trusted' platform to an unknown software hub site
  • Any software guide that asks you to disable protections or add AV exclusions
  • Unnecessary request for administrator privileges for a basic installer
  • Bundled README pushing risky steps to 'make it work'

You search for “Google Gemini for Windows,” click the top result, and it’s on Google Colab… so it feels safe, right? But that Colab page silently bounces you to a fake 'Windows Software Hub' site, serving a file called Download_Google_Gemini_For_Windows.exe that’s actually the Vidar infostealer, built to rip passwords from your browser. The ZIP even includes a README telling you to run it as administrator and add it to your antivirus exclusions. That’s the aha moment: legit installers don’t beg you to weaken your defenses just to 'make it work.' If you ever see AI tool installers from Colab, random 'software hubs,' or READMEs asking for admin and AV exceptions, stop and send the link or file to IT or security before you touch it.
