Android devices are facing an increased uptick in adware, infostealers, and trojans from malicious apps in 2025. Notably, these apps are almost all entirely found within the official Google Play Store or from the pre-installed apps of cheaper, low-end OEMs.
While apps hosting intrusive ads have topped the charts, banking trojans and firmware-level cryto stealers have surged in popularity. The latter could be found among modified versions of WhatsApp and the firmware of said low-cost phones.
