The Federal Government has warned Nigerians, home to over 200 million mobile phone users, to be wary of malicious apps on social media including the popular TikTok, that have been found to hijack Android devices.
The National Information Technology Development Agency (NITDA) which issued what the IT agency cites as “an urgent warning” want Android users to know about four specific malicious applications capable of taking control of their mobile phones.
These apps, NITDA says, are designed to steal information, mine cryptocurrency, and spy on users by monitoring their activities.

According to NITDA, once these malicious apps are installed, the malware activates and uses WebView to launch URLs to platforms like YouTube or a mobile gaming site called CrazyGames.com. While doing so, it exploits its permissions to gain access to locations, SMS messages, contacts, and call logs; make phone calls; take screenshots; and record audio and video.

NITDA on how malicious apps operate
According to NITDA, once these malicious apps are installed, the malware activates and uses WebView to launch URLs to platforms like YouTube or a mobile gaming site called CrazyGames.com. While doing so, it exploits its permissions to gain access to locations, SMS messages, contacts, and call logs; make phone calls; take screenshots; and record audio and video.
This invasive activity, according to NITDA, not only compromises user privacy but also significantly degrades device performance, leading to occasional slowdowns or freezes.
