The Nigerian Communications Commission has warned Nigerians to be wary of new Trojan spyware apps, like Joker app, which can compromise their security. Even worse, these apps are appearing on Google Play Store and masquerading to be helpful.
From clicking online ads for users to approving One Time Password (OTP) for fraudsters, these apps pose a genuine risk to users. They can also steal sensitive information like contacts details and read text messages as well.

Here is the full statement from NCC’s Director of Public Affairs, Dr Ikechukwu Adinde:
“…in a related advisory, the NCC, based on another detection by CSIRT, wishes to inform the general public about the resurgence of Joker Trojan-Infected Android Apps on Google Play Store. This arose due to the activities of criminals who intentionally download legitimate apps from the Play Store, modify them by embedding the Trojan malware and then uploading the app back to the Play Store with a new name.
“The malicious payload is only activated once the apps go live on the Play Store, which enables the apps to scale through Google’s strict evaluation process. Once installed, these apps request permissions that once granted, enable the apps to have access to critical functions such as text messages and notifications.
“As a consequence, a compromised device will subscribe unwitting users to premium services, billing them for services that do not exist. A device like this can also be used to commit Short Messaging Service fraud while the owner is unaware.
“It can click on online ads automatically and even use SMS One Time password to secretly approve payments. Without checking bank statements, the user will be unaware that he or she has subscribed to an online service. Other actions, such as stealing text messages, contacts, and other device data, are also possible.”
