The National Information Technology Development Agency, NITDA, on Monday issued a warning about a new version of the Grandoreiro banking malware, which is targeting users globally through sophisticated phishing campaigns.
In an advisory released by NITDA’s Computer Emergency Readiness and Response Team, the agency described Grandoreiro as a significant threat, using “advanced techniques, including screen overlay attacks and remote device control, to steal sensitive information such as banking credentials and personal data.”
The country’s technology regulator explained that the malware is primarily distributed via phishing emails and fraudulent websites that deceive victims into downloading malicious software disguised as legitimate updates or documents.
Once installed, the malware bypasses security controls, granting attackers unauthorised access to users’ devices.
NITDA warned that the malware could lead to financial losses and identity theft.

“This malware poses a significant risk to individuals and businesses, potentially compromising sensitive financial information and enabling unauthorised transactions,” the advisory stated.
To mitigate the risk, the agency urged the public to exercise caution and adopt recommended security measures.
“Cyber threats like Grandoreiro are evolving, and users need to stay vigilant and adopt robust security practices to protect their information,” the agency advised.
NITDA recommended avoiding links and attachments from unknown emails, downloading software only from trusted sources, and enabling multifactor authentication to secure online banking and financial accounts.
The agency also emphasised the importance of keeping antivirus software updated, avoiding public Wi-Fi for financial transactions, and regularly monitoring bank accounts for unauthorised activities.
The National Information Technology Development Agency is a public service institution established by NITDA Act 2007 as the ICT policy implementing arm of the Federal Ministry of Communication and Digital Economy of the Federal Republic of Nigeria.
It is responsible for developing programmes that cater for the running of ICT-related activities in the country.
