Android Banking Malware SlemBunk Part of Well-Organized Campaign (fireeye.com)
itwbennett writes: Researchers from FireEye first documented the SlemBunk Android Trojan that targets mobile banking users in December. Once installed, it starts monitoring the processes running on the device and when it detects that a mobile banking app is launched, it displays a fake user interface on top of it to trick users into inputting their credentials. The Trojan can spoof the user interfaces of apps from at least 31 banks from across the world and two mobile payment service providers. The attack is more complicated than it appears at first glance, because the APK (Android application package) that users first download does not contain any malicious functionality, making it hard for antivirus apps and even Android's built-in app scanner to detect it.
This is why I don't and never will have a banking app on any mobile device.
