The Nigerian Communications Commission (NCC) has alerted Nigerian telecom users of the existence of a new high-risk and extremely damaging malware called Flubot.
The NCC’s Director of Public Affairs, Mr Ikechukwu Adinde, said the malware is like every other malicious software and program designed specifically to disrupt, damage, or gain unauthorized access to a computer system.
“When Flubot infects a device, it can result in incalculable financial losses. Additionally, the malware creates a backdoor which grants access to the user’s device, thus enabling the invader or attacker to perform other criminal actions, including launching other variants of malware,” he said.
Information from the Nigeria Computer Emergency Response Team (ngCERT) revealed that Flubot malware targets androids with fake security updates and app installations.
The Flubot impersonates android mobile banking applications to draw fake web views on targeted applications, and its goal transcends stealing personal data and essentially targets stealing of credit card details or online banking credentials.
This malware can also be circulated through Short Message Service (SMS) and can snoop on incoming notifications, initiate calls, read or write SMSes, and transmit the victim’s contact list to its control centre.
It attacks Android devices by pretending to be FedEx, DHL, Correos, and Chrome applications and compels unsuspecting users to alter the accessibility configurations on their devices in order to maintain a continuous presence on devices.
The new malware damages the security of devices by copying fake login screens of prominent banks, and the moment the users enter their login details on the fake pages, their data is collected and transmitted to the malware operators’ control point.
This control quarter is where the data is exploited by intercepting banking-related One Time Passwords (OTPs) and replacing the default SMS app on the targeted Android device.
The malware is also capable of securing access into the device through SMS and proceeds to transmit similar messages to other contacts that may be on the device it has attacked, enticing them into downloading the fake app.
In a bid to tackle this malicious action, protect millions of telecom consumers and prevent criminal forces from using telecom platforms to execute fraud and complete damages, the NCC also listed measures to guard against attacks from Flubot.
Telecom users are expected not to install any app or security update following a page request, also not to click on any link when they receive a suspicious text message.
Users should also consider the use of updated antivirus software that detects and prevents malware infections, and apply critical patches to the system and application.
Also, the use of strong passwords and enabling Two-Factor Authentication (2FA) over logins should be embraced.
Data should be Backed-up regularly, and if affected by this campaign, victims should reset their device to factory mode as soon as possible as this will delete any data on your phone, including personal data.
According to the NCC, backups made after installing the malicious program should not be restored, and victims may contact ngCERT platform for technical assistance.
Infected personnel will also need to change the passwords to all of y online accounts, with urgency, around online bank accounts.
If anyone has concerns that their accounts may have been accessed by unauthorized people, they are advised to contact their bank immediately.
