Fake Streaming Ads Push StreamRat Android Trojan

Malwarebytes · Medium sophistication
Last updated September 3, 2026

Researchers found a real malicious ad campaign on Meta platforms (and reused on TikTok) that pushed a fake “free TV streaming” service to Spanish-speaking users, mainly in Spain. Clicking the ad led to a tailored website that coached Android users through installing an app from outside Google Play, resulting in StreamRat malware capable of stealing credentials and remotely controlling the device.

Key findings

  • A malicious paid-ad campaign promoting a fake free streaming service reached roughly 570,000 Meta users, and the same banners were also used on TikTok.
  • The ad click led to a fake streaming website that detected Android devices and only offered the malicious download to Android users.
  • The site tailored step-by-step instructions based on the referral source (Instagram/TikTok/Facebook/browser), including enabling installs from “unknown sources,” to push users past security warnings.
  • StreamRat is described as an Android banking trojan/infostealer that can capture typed data, display convincing fake login screens, and enable remote control of the device.

Who’s being targeted

  • Commonly targeted roles: All staff, Android/mobile device users, Finance (employees who use mobile banking apps).
  • Affected industries: Consumers / general public (mobile users), Social media platforms, Banking/financial services (downstream impact via credential theft).
  • Attack channels: website.
  • Impersonated: A free TV-streaming platform.

Awareness takeaways

  • Don’t install apps directly from ads or direct-download sites; prefer official app stores and verify the developer.
  • Treat any instructions to enable installs from “unknown sources” as a major warning sign.
  • Be suspicious of apps that request powerful permissions that don’t match their purpose (especially Accessibility).
  • If you installed a suspicious APK and granted Accessibility access, isolate the device and change passwords from a different device.

Red flags to watch for

  • The site coaches the user to change security settings to install from “unknown sources.”
  • The app is downloaded from a direct-download website rather than Google Play.
  • The offer is “free streaming” promoted via an ad and requires unusual install steps.

You’re scrolling Instagram and see a sponsored ad: “Watch FREE TV streaming on Android, install the app now.” Looks legit, right? But that ad can send you to a fake streaming site that knows you’re on Android, then walks you through downloading an APK from the web and turning on installs from “unknown sources” step by step. That’s how the StreamRat Android trojan lands: once installed, it can steal what you type, pop up fake banking logins, and let someone remotely poke around your phone like they’re holding it. Here’s the rule: if an ad or website tells you to install an Android app from the browser and enable “unknown sources,” stop and only install that app from the official app store instead.
