Lukas Stefanko, a researcher with ESET said the hackers are making the copy look identical to the Clubhouse website. But once the users click on ‘Get it on Google Play the app automatically gets downloaded onto the user’s phone.
However, the legit Clubhouse App will redirect to Google Play and not download the Android Package Kit (APK).
He further added, it is not clear how the victims discover the website. Perhaps it is spread via social media or third-party websites such as forums. The fake website looks identical to the real one, where users can join via an invite from an existing user. “Sign up to see if you have friends on Clubhouse who can let you in.” message shows up to click. While the real website redirects users to download the app on the store. While the fake site misleads users to get the app on Google Play.
There are many telltale signs on taking a closer look at the fake website. Firstly it is an HTTP connection and not a secure HTTPS. The other indicator is the site uses .mobi a top-level domain rather than the .com used by the legitimate domain.
