10-question quiz on APKs, fake apps, banking trojans, and spyware

Android Threats — Module Quiz
Ten APPLY items on what an APK is (zip of code; package name vs icon), Install unknown apps as a trust switch, chat and “cracked” sideloads skipping store review, Play Protect as a filter, clone Play listings, overlay and Accessibility refusal, OTP-on-a-surprise-prompt, and spyware clues with safety-first if someone close may be involved. Wrong answers still teach. You will not install samples. You will not build overlays, pack APKs, bypass Play Protect, or operate stalkerware. Fictional packages such as com.ultra.battery.example stay on paper. Notes stay in $HOME/cyberlium-lab with chmod 600 — no live bank secrets, no other people’s messages, no shelter addresses. Next after this quiz is Dangerous Permissions to Avoid: still YOUR Settings, still never unknown APKs, still never a bank or a stalkerware sample as a “lab.”
