ESET researchers discovered an uncommon type of phishing campaign targeting Android and iPhone users. They analyzed a case observed in the wild that targeted clients of a prominent Czech bank.

This technique is noteworthy because it installs a phishing application from a third-party website without the user having to allow third-party app installation. On Android, this could result in the silent installation of a special kind of APK, which even appears to be installed from the Google Play store. The threat targeted iOS users as well.
The phishing websites targeting iOS instruct victims to add a Progressive Web Application (PWA) to their home screens, while on Android, the PWA is installed after confirming custom pop-ups in the browser. At this point, these phishing apps are largely indistinguishable from the real banking apps they mimic on both operating systems.
