NCC-CSIRT Warns of Yanluowang Ransomware, Calls for Stronger Security Measures
The Nigerian Communications Commission’s Computer Security Incident Response Team (NCC-CSIRT) has urged organisations to adopt stronger cybersecurity measures like ensuring their employees use strong, unique passwords for every account and enabling multi-factor authentication (2FA) wherever it is supported to prevent ransomware attacks. It also advised organizations to ensure regular systems backup.
The NCC-CSIRT’s warning contained in its advisory of August 12, 2022, came after the Yanluowang threat actors gained access to Cisco’s network using an employee’s stolen credentials after hijacking the employee’s personal Google account containing credentials synchronised from their browser.
Ransomware is a malware designed to deny a user or organization access to files on their computer until they pay the attackers.
Cisco reported the security incident on its corporate network but said it did not identify any impact on its business although the threat actors had published a list of files from this security incident on the dark web on August 10.
NCC-CSIRT estimated potential damage from the incident to be critical while predicting that successful exploitation of the ransomware will result in ransomware deployment to compromise computer systems, sensitive products and customers’ data theft and exposure, as well as huge financial loss to organizations by incurring significant indirect costs and could also mar their reputations.
The team said, “The first step to preventing ransomware attacks is to ensure that employees are using strong, unique passwords for every account and enabling multi-factor authentication (2FA) wherever it’s supported.”
It further disclosed that “In response to the attack, Cisco has immediately implemented a company-wide password reset. Users of Cisco products should ensure a successful password reset.
“As a precaution, the company has also created two Clam AntiVirus signatures (Win.Exploit.Kolobko-9950675-0 and Win.Backdoor.Kolobko-9950676-0) to disinfect any potentially compromised assets. Clam AntiVirus Signatures (or ClamAV) is a multi-platform antimalware toolkit that can detect a wide range of malware and viruses.
“User education is critical in thwarting this type of attacks or any similar attacks, including ensuring that employees are aware of the legitimate channels through which support personnel will contact users, so that employees can identify fraudulent attempts to obtain sensitive information. “Organizations should ensure regular systems backup,” the advisory urged.
The Computer Security Incident Response Team (CSIRT) is the telecom sector’s cyber security incidence centre set up by the NCC to focus on incidents in the telecom sector and as they may affect telecom consumers and citizens at large.
The CSIRT also work collaboratively with the Nigeria Computer Emergency Response Team (ngCERT), established by the Federal Government to reduce the volume of future computer risks incidents by preparing, protecting and securing the Nigerian cyberspace to forestall attacks, problems or related events.
In the wake of increasing geopolitical tension, Cassava Technologies has unveiled its National Sovereign Cloud offering for African governments.
The solution, the company claims, will help the continent’s governments ensure data is kept on infrastructure that remains under local legal and operational jurisdiction.
According to the official announcement, made yesterday, the solution provides “secure, locally-governed digital infrastructure that enables the deployment of AI-enabled public services”.
The overarching solution encompasses cloud, cyber security, AI computing infrastructure, as well as local language AI models and skills support for governments.
The announcement comes amid increasing uncertainty over the hosting of sensitive national data on cloud services operated by foreign hyperscalers, which are subject to legal frameworks, such as the U.S. CLOUD Act. The CLOUD Act opens the door to allow American authorities to access data stored on the servers of US hyperscalers, wherever those servers are physically located.
Cassava has claimed separately that currently, “approximately 33% to 45% of the world’s data is hosted in the USA”.
The company added: “A sovereign cloud reduces exposure to extraterritorial laws, improves cyber resilience, and ensures that model weights and training data for public AI remain under national custody.”
The Africa Data Centres Association’s 2026 Economic Report states that “data sovereignty has evolved from a legal aspiration into a strategic policy lever”.
Ahmed El Beheiry, Group COO and Group Chief Technology and AI Officer, Cassava Technologies said: “Across Africa, governments are accelerating their digital transformation agendas and are increasingly focused on ensuring that data and digital infrastructure remain secure and sovereign.”
Announced at the Mobile Word Congress in Barcelona, this week, the Sovereign Cloud offering launch accompanied the launch of Cassava’s Cloud Partner programme.
The partner programme targets mobile network operators and system integrators across Africa to resell and distribute AI, cloud, and other digital services using Cassava’s infrastructure and technology platforms.
El Beheiry added: “We are expanding Africa’s sovereign AI ecosystem to build solutions that address the continent’s unique challenges while creating new opportunities for growth and digital inclusion.”
The programme offers partners access to NVIDIA Cloud Partner solutions, Cassava’s AI Factory, its own native AI solutions and its AI Multi-Model Exchange, which supports both Anthropic’s Claude and Google’s Gemini models.

The notice, signed by company secretary Uto Ukpanah, stated: “This is to enable Mr. Mroue to focus on other priorities within MTN Group Limited. The Board wishes to express its appreciation to Mr. Mroue for his immense service to MTN Nigeria and wishes him success in his future endeavours.”
Mroue joined MTN Nigeria’s board on June 1, 2022, bringing over 28 years of telecom experience. A veteran MTN executive, he previously served as CEO of MTN Uganda and MTN Liberia, non-executive director at MTN Cyprus, and held leadership roles at MTN Ghana.
Since February 2022, he has been MTN Group’s Chief Technology and Information Officer, overseeing technology strategy and governance. Earlier, as MTN Nigeria’s COO from August 2018 to January 2022, he also sat on the MTN Nigeria Foundation board.
The exit follows MTN Nigeria’s stellar 2025 results, posting a ₦1.70 trillion profit before tax—reversing a ₦550.3 billion loss in 2024 driven by forex woes—marking one of the telco’s strongest rebounds.
Google has rolled out support for Yorùbá and Hausa languages in its AI-powered Search features—AI Overviews and AI Mode—enabling millions of Nigerians to get quick answers, summaries, and conversational web exploration in their mother tongues.
The update forms part of Google’s push to cover 13 African languages, including Afrikaans, Akan, Amharic, Kinyarwanda, Afaan Oromoo, Somali, Sesotho, Kiswahili, Setswana, Wolof, and isiZulu, selected based on high search activity across the continent.
Now, a Kano student can ask complex questions in Hausa, while an Ibadan trader seeks business tips in Yorùbá—both receiving culturally nuanced AI responses via text or voice on Android, iOS, or web.
Taiwo Kola-Ogunlade, Google’s West Africa Communications Manager, said: “Building truly global Search requires nuanced local understanding. With Gemini-powered AI, we’ve made advanced capabilities relevant in Yorùbá and Hausa, so Nigerians converse naturally with Search in their mother tongues.”
To use: Open the Google app, tap AI Mode, and query in Hausa or Yorùbá for personalised guidance—breaking language barriers and making technology reflect Nigeria’s diverse identity.
