NCC alerts on new Malware AbstractEmu, attacking android devices

The Nigerian Communications Commission (NCC) has alerted telecom consumers and the general public that a new Android malware has been discovered.

NCC in a statement by the Director, Public Affairs, Dr Ikechukwu Adinde, said the malware, named ‘AbstractEmu’, can gain access to smartphones, take complete control of infected smartphones and silently modify device settings while simultaneously taking steps to evade detection.

The statement said this discovery was announced recently by the Nigerian Computer Emergency Response Team (ngCERT), the national agency established by the Federal Government to manage the risks of cyber threats in Nigeria, which also coordinates incident response and mitigation strategies to proactively prevent cyber-attacks against Nigeria

“AbstractEmu has been found to be distributed via Google Play Store and third-party stores such as the Amazon Appstore and the Samsung Galaxy Store, as well as other lesser-known marketplaces like Aptoide and APKPure.

“The advisory stated that a total of 19 Android applications that posed as utility apps and system tools like password managers, money managers, app launchers, and data saving apps have been reported to contain the rooting functionality of the malware.

“The apps are said to have been prominently distributed via third-party stores such as the Amazon Appstore and the Samsung Galaxy Store, as well as other lesser-known marketplaces like Aptoide and APKPure. The apps include All Passwords, Anti-ads Browser, Data Saver, Lite Launcher, My Phone, Night Light and Phone Plus, among others.

“According to the report, rooting malware although rare, is very dangerous. By using the rooting process to gain privileged access to the Android operating system, the threat actor can silently grant itself dangerous permissions or install additional malware – steps that would normally require user interaction. Elevated privileges also give the malware access to other apps’ sensitive data, something not possible under normal circumstances”, the statement said.

NCC further said the ngCERT advisory also captured the consequences of making their devices susceptible to AbstractEmu attack. Once installed, the attack chain is designed to leverage one of five exploits for older Android security flaws that would allow it to gain root permissions.

The Commission said it also takes over the device, installs additional malware, extracts sensitive data, and transmits to a remote attack-controlled server.

“Additionally, the malware can modify the phone settings to give app ability to reset the device password, or lock the device, through device admin; draw over other windows; install other packages; access accessibility services; ignore battery optimisation; monitor notifications; capture screenshots; record device screen; disable Google Play Protect; as well as modify permissions that grant access to contacts, call logs, Short Messaging Service (SMS), Geographic Positioning System (GPS), camera, and microphone.

“The ngCERT also asserts in the advisory that, while the malicious apps were removed from Google Play Store, the other app stores are likely distributing them”, NCC noted.

To mitigate the risk, NCC said “users should be wary of installing unknown or unusual apps, and look out for different behaviours as they use their phones.

“Reset your phone to factory settings when there is suspicion of unusual behaviours in your phone”.
