Nigerian Government Sounds Alarm on Rising Ransomware Attacks Targeting Citizens and Businesses

2025-01-27

In an era where digital transformation is reshaping industries, cyber threats are becoming increasingly sophisticated and pervasive. The Nigerian government has recently raised the alarm over a surge in ransomware attacks targeting both individuals and businesses. This wave of cybercrime, led by the notorious Phobos ransomware, poses a significant threat to the nation’s digital infrastructure. With critical sectors like healthcare, education, and telecommunications under fire, the government is urging citizens and organizations to bolster their cybersecurity measures. Here’s a detailed look at the situation and what it means for Nigeria’s digital future.

The Nigerian government, through the Nigeria Computer and Emergency Response Team (ngCERT), has issued a high-level alert regarding a sharp increase in ransomware attacks. These attacks, primarily orchestrated by the Phobos ransomware group, are targeting critical cloud service providers and other vulnerable sectors within Nigeria’s cyberspace. The ngCERT, operating under the Office of the National Security Adviser (NSA), has classified the threat as “high and critical,” emphasizing the urgency of the situation.

The most at-risk sectors include technology and telecommunications, education, healthcare, service providers, and non-governmental organizations (NGOs). The attackers exploit weak networks by using phishing campaigns to deliver hidden payloads or by leveraging tools like Angry IP Scanner to identify vulnerable Remote Desktop Protocol (RDP) ports. Once inside, they deploy spoofed email attachments containing malicious payloads, such as Smoke Loader, to initiate further attacks.

This alarming development coincides with a rise in insider fraud within Nigerian banks. Recently, commercial banks dismissed 93 employees for fraudulent activities, including a case where a staff member allegedly stole N44 billion from customer accounts. Additionally, the Nigerian Communications Commission’s Computer Security Incident Response Team (NCC-CSIRT) has identified five malicious Google Chrome extensions that secretly track users’ online activities and steal sensitive data.

The government is urging organizations to secure their RDP ports and adopt robust cybersecurity practices to mitigate these threats. The ngCERT is also collaborating with affected entities to resolve incidents and prevent future attacks.

What Undercode Say:

The recent surge in ransomware attacks in Nigeria underscores the growing sophistication of cybercriminals and the vulnerabilities within the nation’s digital infrastructure. Phobos ransomware, in particular, has emerged as a formidable threat, exploiting weak networks and unsecured RDP ports to infiltrate systems. This trend is not unique to Nigeria; globally, ransomware attacks have increased by over 150% in the past year, with attackers targeting critical sectors like healthcare and education.

One of the most concerning aspects of this situation is the exploitation of RDP ports. RDP, a protocol widely used for remote access, has become a favorite entry point for cybercriminals. When left unsecured, it provides an open door for attackers to deploy malicious payloads and exfiltrate sensitive data. Organizations must prioritize securing these ports by implementing strong passwords, multi-factor authentication, and regular security audits.

The rise in insider fraud within Nigerian banks further highlights the need for comprehensive cybersecurity strategies. Insider threats are particularly challenging to detect and prevent, as they often involve trusted employees with access to sensitive systems. Banks and other financial institutions must invest in advanced monitoring tools and employee training programs to mitigate these risks.

The discovery of malicious Google Chrome extensions by the NCC-CSIRT is another reminder of the importance of vigilance in the digital age. Browser extensions, while convenient, can pose significant security risks if not properly vetted. Users should regularly review and remove unnecessary extensions, ensuring they only install those from trusted sources.

From a broader perspective, this wave of cyberattacks reflects the urgent need for a coordinated national cybersecurity strategy. While the ngCERT’s efforts are commendable, more resources and collaboration are required to combat these threats effectively. Public-private partnerships, increased funding for cybersecurity initiatives, and widespread awareness campaigns are essential to building a resilient digital ecosystem.

For individuals and businesses, the key takeaway is clear: cybersecurity is no longer optional. Implementing robust security measures, staying informed about emerging threats, and fostering a culture of cyber awareness are critical steps in safeguarding against ransomware and other cyberattacks. As Nigeria continues its digital transformation journey, addressing these challenges will be pivotal in ensuring a secure and prosperous future.

By understanding the gravity of these threats and taking proactive measures, Nigeria can turn the tide against cybercriminals and protect its digital landscape. The time to act is now.
