The Nigerian Communications Commission (NCC) has alerted Nigerians of a malicious app called ”Fast Cleaner” that steals the banking app login details on Android phone users.
Ikechukwu Adinde, NCC director of public affairs, issued the warning in a statement released this weekend.
Adinde said the NCC Computer Security Incident Response Team (CSIRT) discovered the Fast Cleaner app which claims to be a phone booster and battery saver tool but actually contains a malware named ‘Xenomorph’.
He said the application’s main operation is to steal credentials, combined with the use of SMS and notification interception to log-in and use potential two-factor authentication tokens.
“Xenomorph is propagated by an application that was slipped into Google Play store and masquerading as a legitimate application called “Fast Cleaner” ostensibly meant to clear junk, increase device speed and optimize battery. In reality, this app is only a means by which the Xenomorph Trojan could be propagated easily and efficiently.
To avoid early detection or being denied access to the PlayStore, “Fast Cleaner” was disseminated before the malware was placed on the remote server, making it hard for Google to determine that such an app is being used for malicious actions.
Once up and running on a victim’s device, Xenomorph can harvest device information and Short Messaging Service (SMS), intercept notifications and new SMS messages, perform overlay attacks, and prevent users from uninstalling it. The threat also asks for Accessibility Services privileges, which allow it to grant itself further permissions.
The CSIRT said the malware also steals victims’ banking credentials by overlaying fake login pages on top of legitimate ones.
