Android Trojan

According to the report by ESET, the Trojan affects the victim’s Android device initially through a battery optimization app that the user might have installed from the official Google Play Store in their device or through an APK file from a third party resource.

The Trojan attacks the victims’ device as soon as the malicious app is opened. It immediately hides the app icon without launching and prompts the user into accepting an accessibility service on their Android device called enable statistics.

Once the user has enabled this malicious accessibility service, the Trojan would now send a notification to the victim asking him to launch the official PayPal app if installed on their device.

As soon as the victim launches the PayPal app on their device and logs in to his account#, the malicious accessibility service will now forge the user into sending a specific amount of a money to the attacker’s PayPal email address.

Since the victim is just forged into sending money to the attacker by logging into his PayPal account, instead of stealing the login credentials of the user and trying to login by itself, it is able to bypass the two factor authentication feature enabled by the user.

The malicious accessibility service is said to be activated every time an user opens the official PayPal account which means it can steal the user’s money multiple times.

However, it does not perform any malicious activity if there is no sufficient balance or a card has not been linked to the PayPal account of the victim.
