Quick Heal Security Labs detected an Android Banking Trojan that targets more than 232 banking apps including those offered by Indian banks. The malware is known as Android.banker.A2f8a (Previously detected as Android.banker.A9480).
Like most other Android banking malware, even this one is designed for stealing login credentials, hijacking SMSs, uploading contact lists and SMSs on a malicious server, displaying an overlay screen (to capture details) on top of legitimate apps and carrying out other such malicious activities.
Android.banker.A2f8a is being distributed through a fake Flash Player app on third-party stores. This is not surprising given that Adobe Flash is one of the most widely distributed products on the Internet. Because of its popularity and global install base, it is often targeted by attackers.
After installing the malicious app, it will ask the user to activate administrative rights. And even if the user denies the request or kills the process, the app will keep throwing continuous pop-ups until the user activates the admin privilege. Once this is done, the malicious app hides its icon soon after the user taps on it. In the background, the app carries out malicious tasks – it keeps checking the installed app on the victim’s device and particularly looks for 232 apps (banking and some cryptocurrency apps).
If any one of the targeted apps is found on the infected device, the app shows a fake notification on behalf of the targeted banking app. If the user clicks on the notification, they are shown a fake login screen to steal the user’s confidential info like net banking login ID and password.
Indicator of compromise is following app has been installed.

Adobe had also announced that it will stop updating and distributing Flash player by the end of 2020 in all formats of browser.
Tips to stay safe
- Avoid downloading apps from third-party app stores or links provided in SMSs or emails.
- Always keep ‘Unknown Sources’ disabled. Enabling this option allows installation of apps from unknown sources.
- Most importantly, verify app permissions before installing any app even from official stores such as Google Play.
- Install a reliable mobile security app that can detect and block fake and malicious apps before they can infect your device.
- Always keep your device OS and mobile security app up-to-date.
