The apps that criminals use are known as “Android Dropper,” which is a subtype of malware that aims to allow another malicious file to run. In this case, seventeen apps share a dropper, or DawDropper, and present themselves as productivity tools and utilities, such as a QR code reader and document scanner. The term used (dropper) refers specifically to the slow and accurate transfer of users’ personal data.
Trend Micro states that DawDropper uses an online database called Firebase Realtime Database, a cloud storage service, to avoid detection by security tools and dynamically obtain an address to download the payload.
Thus, it means that the criminals are operating through the cloud storage with enough space for downloading the downloads. The company claims that malicious download payloads are also uploaded to GitHub.
How do attacks work?
Droppers are apps that are built to pass the security checks of the Google Play Store. However, they are then used to download invasive malware on electronic equipment, such as Octo (Coper), Hydra, Ermac and TeaBot. So, it all starts with the user downloading the app, and once it’s installed, the attack sequence begins as the apps that are part of DawDropper establish connections with cloud databases to receive the link to the malicious content and install on the device.
All the apps involved in the scam have been removed from the Play Store. But check out the list and see if you’ve downloaded any in the past few months:

Octo malware, for example, disables Google Play Protect and uses remote computing to record victims’ device screen and activity, including confidential banking information, email and app passwords being sent to a remote server.
According to Trend Micro, more and more cybercriminals are specialized and seeking to manipulate the security mechanisms of stores and illegally capture data from the largest number of users. It is necessary to be attentive.
