I'm quite curious, I understand correctly that these drainer accidents so far happened to PC users? How likely is same situation happen to people who access their wallet through mobile device [tablet and phone]? Android has these "block third party installation" things [not sure what they really called] where we need to manually grant an apk installation from app other than play store and other official app market, but how "compatible" is those drainer with android or iOS? Can they be executable on both OS or [currently] they're only spread through PC?
Of course, if a mobile phone user, especially an Android user, downloads any applications outside the official stores from unknown sources in APK format and ignores the security feature that prevents the installation of apps from unknown sources, then these malicious or fake applications can, through the permissions granted by the user, access private data, violate user privacy, and drain wallets.
What happened with the OP was that he downloaded the Pumpfun sniper bot, which was developed in exe format for the computers that contained Malware. However, unscrupulous developers can develop an APK version to target phone users. Therefore, anyone should avoid downloading anything before being aware of security measures and ensuring that his sensitive data is in a safe place, not connected to the internet.
