Frequently Asked Questions
Questions we hear every day.
Everything you need to know about fake APKs and sideloaded app risks.
What is a fake APK?
A fake APK is a malicious Android app disguised as a legitimate one — often mimicking courier tracking, banking, or WhatsApp apps — designed to steal your data or spy on your device once installed.
How do I know if an APK is fake or unsafe?
Fake APKs are almost always installed outside the Google Play Store, often via a link sent through WhatsApp or SMS. Arjuna checks where every app on your device was installed from and verifies its signature against the real developer's.
Is sideloading apps always dangerous?
Not always — sideloading is common for beta apps or regional software. The risk is when a sideloaded app impersonates a trusted brand like a bank. Arjuna flags this specific pattern rather than blocking all sideloading.
Can a fake courier APK steal my banking details?
Yes. Fake courier tracking apps are one of the most common APK scams in India — they often request excessive permissions and contain hidden keyloggers or SMS readers that can capture OTPs and banking credentials.
