Scamming - Fraud
The website smallboi.app is malicious. The website tricks visitors into downloading spam or malicious apps by claiming they need to do so in order to download apps they can get from Google Play Store and Apple App Store. If you are sent messages with a link to ogzilla.net, please do not click it, just delete it.
Visitors to ogzilla.net will be redirect to the untrustworthy cswsaa.com, where the website will pretend to download the app or game selected. In the example below, we are attempting to download Apple Music (do not do this)
Visitors will then be asked to download additional files required to complete the download. But this only a trick into getting the visitors to go to the malicious website, smallboi.app, where they will be asked to download malicious apps.
If you have installed apps via ogzilla.net, cswsaa.com or smallboi.app, please remove them from your smartphone or mobile device. And, it is recommended that you change your online account passwords.
