Zero-day in Microsoft Windows Used in Nokoyawa Ransomware Attacks

In February, Kaspersky experts discovered an attack using zero-day vulnerability in the Microsoft Common Log File System (CLFS). A cybercriminal group used an exploit developed for different versions and builds of Windows OS including Windows 11 and attempted to deploy Nokoyawa ransomware.

Microsoft assigned CVE-2023-28252 to this vulnerability and patched it on April 11th. The threat actor also attempted to execute similar elevation of privilege exploits in attacks on different small and medium-sized businesses in the Middle East and North America, and previously in Asia regions.
While most of the vulnerabilities discovered by Kaspersky are used by APTs, this one turned out to be exploited for cybercrime purposes by a sophisticated group that carries out ransomware attacks.
This group stands out by the usage of similar but unique Common Log File System (CLFS) exploits. Kaspersky has seen at least five different exploits of this kind. They were used in attacks on retail and wholesale, energy, manufacturing, healthcare, software development and other industries.
Microsoft assigned CVE-2023-28252 to the discovered zero-day. This is the Common Log File System elevation of privilege vulnerability which gets triggered by the manipulation of file format used by this subsystem.
Kaspersky researchers uncovered the vulnerability in February as a result of additional checks into a number of attempts to execute similar elevation of privilege exploits on Microsoft Windows servers belonging to different small and medium-sized businesses in the Middle Eastern and North American regions.
CVE-2023-28252 was first spotted by Kaspersky in an attack where cybercriminals attempted to deploy a newer version of Nokoyawa ransomware. Older variants of this ransomware were just “rebranded” variants of JSWorm ransomware, but in the aforementioned attack the Nokoyawa variant was quite distinct from JSWorm in terms of a codebase.
The exploit used in the attack was developed to support different versions and builds of Windows OS including Windows 11. Attackers used CVE-2023-28252 vulnerability to elevate privileges and steal credentials from the Security Account Manager (SAM) database.
“Cybercrime groups are becoming increasingly more sophisticated using zero-day exploits in their attacks. Previously it was primarily a tool of Advanced Persistent Threat actors (APTs), but now cybercriminals have the resources to acquire zero-days and routinely use them in attacks.
There are also exploit developers willing to help them and develop exploit after exploit. It’s very important for businesses to download the latest patch from Microsoft as soon as possible, and use other methods of protection, such as EDR solutions,” said Boris Larin, Lead Security Researcher with the Global Research and Analysis Team (GReAT) at Kaspersky.

REA, NBS Partner to Deliver Comprehensive Energy Data for Nigeria

The Rural Electrification Agency (REA) and the National Bureau of Statistics (NBS) have signed a Memorandum of Understanding (MoU) to conduct a nationwide energy survey aimed at closing long-standing data gaps in Nigeria’s power sector. The initiative is expected to guide policy, attract investment, and accelerate universal electricity access.

Signed in Abuja, the agreement establishes a National Energy Survey based on the Multi-Tier Tracking Framework (MTF), a globally recognized methodology that measures electricity access not only by grid connection but also by quality, affordability, reliability, and usage of electricity and clean cooking solutions.
The survey will be implemented under the Energy Sector Management Assistance Program (ESMAP) of the World Bank. Dr. Abba Aliyu, REA Managing Director/CEO, said the partnership underscores REA’s commitment to evidence-based rural electrification planning and will generate detailed insights on electricity access and off-grid solutions nationwide.
Prince Adeyemi Adeniran, Statistician-General of the Federation/CEO of NBS, emphasized that reliable statistics are essential for effective policymaking, assuring that NBS will provide technical oversight, sampling expertise, and quality assurance to meet global standards.
The survey will assess energy access, household affordability, expenditure patterns, and the adoption of off-grid technologies such as solar home systems, mini-grids, and clean cooking solutions. REA will provide sector expertise and policy alignment, while NBS manages regulatory approvals, methodology, and technical supervision.
Funded and technically overseen by the World Bank, the exercise will run for 18 months, with the resulting data expected to improve national energy planning, programme targeting, and private sector investment, particularly in underserved and rural communities.
Officials said the collaboration reflects the Federal Government’s commitment to strengthening inter-agency coordination, enhancing energy data availability, and advancing Nigeria’s goal of universal electricity and clean cooking access.

SiBAN New Executive Council to Champion Vision for Nigeria’s Digital Economy

The Stakeholders in Blockchain Technology Association of Nigeria (SiBAN), the nation’s foremost self-regulatory body for the blockchain industry, has completed its election cycle, heralding the beginning of a new executive council dedicated to scaling Nigeria’s digital economy.

The highly anticipated elections concluded recently with the emergence of a new leadership team poised to champion industry standards, foster innovation, and drive widespread adoption of blockchain technology across the country.
The newly elected executives, who will officially assume their roles in January 2026, represent a blend of legal, financial, and technical expertise critical for navigating the evolving regulatory landscape.
Leading the charge is Mela Claude-Ake, a lawyer, who has been elected the President of SiBAN to succeed the outgoing President, Obinna Iwuno, whose tenure was marked by significant achievements, including facilitating crucial reforms and forging strategic partnerships with regulators and other critical stakeholders in the digital asset industry. Mr. Iwuno will formally hand over the reins to the new council in January 2026.
Other elected to the executive council are Chimene Chinah – Vice President 1, in charge of Blockchain education and adoption; Oroke Cornelius – Vice President 2, in charge of membership, strategic partnerships, and funding; and Ayo Shonibare – Vice President 3, in charge of policy, regulation, and ethics.
Others are Ugochukwu Peters – Vice President 4 in charge of digital asset operations and capital markets, Mbene Vivian – Chief strategy officer in charge of projects and incubation, Olufunmilayo Tugbobo as Financial Secretary/Chief Financial Officer, and Chiemeka David Ohajionu as Chief Communications Officer.
The newly elected council’s structure reflects SiBAN’s commitment to addressing key pillars of the blockchain ecosystem: from grassroots education and fostering innovation through projects, to establishing robust regulatory frameworks.
In his acceptance speech, Mela Claude-Ake emphasized the vital role SiBAN plays in shaping the future of finance and technology in Nigeria.
“The trust placed in this new council is not one we take lightly. We inherit a great foundation built by the outgoing team. Our mission now is to accelerate. We stand at a critical juncture where the potential of blockchain to revolutionize every sector, from finance and governance to supply chain, is undeniable. This new council will focus relentlessly on advancing smart, collaborative regulation, democratizing blockchain education, and protecting the interests of all stakeholders to ensure that Nigeria remains a leader in the African digital economy space,” he assured.
He added that he is humbled by the opportunity to be the face of one of Nigeria’s youngest and most promising sectors — blockchain tech.
“As a tech enthusiast I am excited at the possibilities. The ecosystem needs careful nurturing by the government. My administration will be focused on building new bridges for the blockchain sector internationally and domestically, establishing trust with the public and unifying the sector. I enjoin all blockchain stakeholders in Nigeria, connected to Nigeria or of nigerian heritage to join hands together with my administration in building the industry of our dreams.”
The industry now looks forward to the handover ceremony in January 2026 and the initiatives the new SiBAN leadership will unveil to solidify the association’s role as a catalyst for innovation and a respected partner to the Nigerian government.
