Fake AI Tools Steal Logins and Push Malware

Last updated October 15, 2026

A weekly incident roundup describes multiple real-world attacks where criminals used "AI" branding to trick people into handing over passwords/MFA codes or running harmful PowerShell commands. The write-up includes two practical, repeatable social-engineering workflows: fake AI-platform login pages that steal credentials and Custom GPTs that persuade users to execute commands that install malware.

Key findings

  • Attackers used fake "AI" services to spoof Google and Okta login pages and capture passwords and MFA codes.
  • Attackers used Custom GPTs to convince Windows users to run PowerShell commands that kick off a multi-stage malware infection and persistence.
  • After compromising accounts (especially advertising/admin portals), attackers may add unauthorized administrators to preserve access.

Who’s being targeted

  • Commonly targeted roles: Marketing, Finance, All employees (Windows users), IT / Identity & Access Management.
  • Affected industries: Advertising/Marketing teams using ad platforms, Any organization using SSO (Google/Okta) for business apps, Software/IT teams using AI tools and Windows endpoints.
  • Attack channels: website.
  • Impersonated: ChatGPT / Gemini / Claude (fake AI advertising tool) with Google/Okta login, Custom GPT / AI assistant.

Awareness takeaways

  • Treat “run this PowerShell command to verify/fix/install” prompts as a likely scam; stop and contact IT/security through known channels.
  • Verify the website/service before entering credentials, especially when it offers “AI tools” and redirects to Google/Okta login pages.
  • For high-impact platforms like advertising accounts, routinely review admins/roles and investigate any newly added privileged users immediately.

Red flags to watch for

  • The site is a lookalike “AI tool” asking for Google/Okta credentials unexpectedly
  • MFA prompts appear in an unusual flow or at an unusual time
  • After login, account roles/admins change without a normal request
  • Any site/AI tool asking you to run PowerShell commands as a “verification” step
  • Commands that download/install software or change system settings
  • Unexplained scheduled tasks or startup/Run key changes after the action

You see a shiny “AI ad booster” site saying, “Sign in with Google to unlock AI campaign automation.” Looks legit, right? But this “AI” site is a credential trap. It spoofs Google and Okta login screens, captures your password and MFA code, then quietly adds a new admin to your ad account. There’s a second twist: malicious Custom GPTs saying, “To verify you’re not a bot, open PowerShell and run this command.” That command kicks off a multi-stage infection and installs a remote access trojan. Aha moment: real AI tools never need your password on some random site or a “verification” PowerShell script. If any AI page asks for Google or Okta login or PowerShell commands, stop and contact IT or security through our normal help channel.
