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.

FG Plans EO to Criminalise Fiber Cable Damage Costing Telcos Billions

Nigeria will criminalize the destruction of broadband fiber cables following repeated complaints by MTN Nigeria Communications Plc and other telecommunications companies that they are losing billions of naira, according to people familiar with the matter.

FG Plans EO to Criminalise Fiber Cable Damage Costing Telcos Billions

Federal ministry of works, which supervises federal road constructors, is finalizing the regulation that will be signed as an executive order by President Bola Tinubu, said the people, asking not to be identified as they weren’t authorized to comment.

While there are presently laws against vandalism, the authorities are aiming to regulate construction firms more closely.

The order will enforce stiff penalties on offenders, said the people, declining to provide more details or say when it will be signed.

“Telecom assets are critical backbone that supports the economy across sectors,” said Temitope Ajayi, a senior presidential aide, who noted that the Association of Telecommunications Companies (ATCON) has been demanding the classification for years.

New rules will provide “further assurance that the Nigerian government will protect their investments against vandals and criminal elements.”

The Nigerian Communications Commission (NCC) estimates that the sector will make up more than a fifth of the country’s gross domestic product by the end of 2027, up from 13.5% in the third quarter of last year.

The move will help alleviate pressure on the telecoms sector, which is facing increased operating costs and sales pressures from a sharp depreciation in the currency and a threefold increase in energy prices.

Repairs and revenue losses from damaged cables is estimated to have cost the sector almost 27 billion naira ($23 million) last year alone, documents seen by Bloomberg show.

MTN Nigeria, the biggest wireless operator in Africa’s most-populous nation, and Airtel Africa Plc bore the brunt of the costs, the documents show.

MTN suffered more than 6,000 cuts on its fiber cable last year, the documents show. On Feb. 28, a cut on its network in three different locations by a road construction firm, an oil serving company and someone burning rubbish in a manhole meant customers faced more than five hours of data and voice outages.

The operator relocated 2,500 kilometers (1,553 miles) of vulnerable fiber cables between 2022 and 2023, at a cost of more than 11 billion naira – enough to build 870 kilometers of new fiber lines to areas without coverage.

A presidential order on the matter would be welcomed, said Tony Izuagbe Emoekpere, president, Association of Telecommunications Companies of Nigeria.

“When it comes to communication infrastructure, they are destroyed at will, so we are eagerly awaiting the president’s order,” he said. “It would be a great boost to the industry, and it will also encourage investment.”

Telegram, the messaging giant founded by Pavel Durov and headquartered in Dubai, anticipates hitting a remarkable milestone of one billion active monthly users within the next year.

Durov’s departure from Russia in 2014, prompted by governmental pressures to stifle opposition communities on his VK social media platform, underscores Telegram’s commitment to neutrality despite geopolitical challenges.

With 900 million active users currently, Telegram stands as a beacon of free speech in the digital realm, particularly influential in former Soviet Union republics and pivotal during conflicts like the Russia-Ukraine standoff.

Durov’s staunch advocacy for freedom of expression and opposition to censorship by tech giants like Apple and Google reinforces Telegram’s status as a neutral platform.

Opting for the UAE as its base, Durov cites its neutrality and openness as conducive to Telegram’s ethos, serving both opposition groups and governments alike while maintaining impartiality.

In Durov’s vision, the pursuit of freedom eclipses material gain, shaping Telegram’s trajectory as a bastion of digital liberation.

During the meeting between the Director-General of NITDA, Kashifu Inuwa Abdullahi, and Director General of NIMC, Engr. Bisoye Coker-Odusote, with some management staff of both organisations, they discussed various initiatives, which include building DPI stacks for a secured and seamless data exchange and forming partnerships to transform the national identity system.

This collaboration also aims to harness the potential of the innovative ecosystem and emphasise the use of Public Key Infrastructure (PKI) to drive digital transformation in Nigeria.

To ensure a smooth implementation, a 12-man committee was set up. This committee will play a crucial role in kickstarting and harmonising the initiatives. It is expected to deliver a comprehensive implementation report within the next 4 weeks
