ngCERT Issues High Alert to Nigerians Using Android Phones

Nigeria Computer Emergency Response Team (ngCERT) has raised alarms over a new wave of advanced cyberattacks targeting Android mobile phones through a malware campaign dubbed Tria Stealer.

The malicious software is designed to infiltrate Android devices, hijack messaging accounts, intercept One-Time Passwords (OTPs), to steal sensitive personal and financial data.Best Android smartphones

According to ngCERT, Tria Stealer spreads primarily through deceptive tactics, such as fake event invitations distributed via popular messaging platforms like WhatsApp and Telegram.

Unsuspecting users are enticed to download an infected  (APK) file, often disguised as a harmless system application, to evade detection.

Once installed, Tria Stealer requests extensive permissions, including access to SMS, call logs, and app notifications.

It immediately commences data harvesting activities, sending stolen information to a Command and Control (C2) server operated via Telegram bots.

This trojan spreads through fake links, usually disguised as wedding or event invites, and tricks users into downloading malicious APK files

“Account takeover of messaging platforms. Impersonation of victim for fraudulent money transfer requests. Compromise of banking and financial applications. Identity theft and credential harvesting.”

In plain terms, if your phone is compromised, the consequences could be catastrophic.

Your financial apps are vulnerable, your reputation could be ruined by impersonation and even simple personal messages could be twisted into tools for scams.

Here’s what users should be doing now:

Don’t download apps outside the official Play Store.

Be suspicious of random invites or links, even from people you know.

Turn on 2FA for everything—banking, emails, social platforms.

Get a reputable antivirus and keep it updated.

If you run an organisation, you should already be taking this seriously.

ngCERT’s guidance says you should raise awareness, monitor mobile devices, and not let your team click on unverified links.Smartphone deals

“Deploy network monitoring for suspicious outbound connections to known C2 domains,” it said, meaning, keep an eye on every digital door in and out.

This isn’t one of those cases where you wait to see if it affects you. By the time you realise it, it may already be too late.
