Hackers Shift to SIM Cloning

United Nations has discovered significant vulnerabilities in mobile phone technology that could potentially enable hackers to remotely attack at least half a billion SIM cards.

A United Nations (UN) group given to online security plans, warned counties to send out an alert about the underground plans.

A report following a discovery a German firm, earlier in the year showed a bug on the SIM cards which allows hackers to remotely gain control of and also clone certain mobile SIM cards.

The hackers have the capability to use compromised SIMs to commit financial crimes or engage in electronic espionage, according to Berlin’s Security Research Labs, which described the vulnerabilities at the Black Hat hacking conference that in Las Vegas on July 31.

The UN’s Geneva-based International Telecommunications Union, which has reviewed the research, described it as “hugely significant.”

“These findings show us where we could be heading in terms of cyber-security risks,” Hamadoun Touré, ITU secretary general told Reuters.

The ITU he said would notify telecommunications regulators and other government agencies in nearly 200 countries about the potential threat and also reach out to hundreds of mobile companies, academics and other industry experts.

It is thought that many of the 200 countries mentioned in the report are in Africa.

A spokeswoman for the GSMA, which represents nearly 800 mobile operators worldwide, said it also reviewed the research.

“We have been able to consider the implications and provide guidance to those network operators and SIM vendors that may be impacted,” said Claire Cranton, GSMA spokeswoman,

Cracking SIM cards has long been the Holy Grail of hackers because the tiny devices are located in phones and allow operators to identify and authenticate subscribers as they use networks.

Once a hacker copies a SIM, it can be used to make calls and send text messages impersonating the owner of the phone, according to Karsten Nohl, the chief scientist who led the research team.

Nohl said he conservatively estimates that at least 500 million phones are vulnerable to the attacks he will discuss at Black Hat. He added that the number could grow if other researchers start looking into the issue and find other ways to exploit the same class of vulnerabilities.

The ITU estimates some 6 billion mobile phones are in use worldwide. It plans to work with the industry to identify how to protect vulnerable devices from attack, Touré said.

“If you have a MasterCard number or PayPal data on the phone, we get that too,” if it is stored on the SIM, he said.

The newly identified attack method only grants access to data stored on the SIM, which means payment applications that store their secrets outside of the SIM card are not vulnerable to this particular hacking approach.

The mobile industry has spent several decades defining common identification and security standards for SIMs to protect data for mobile payment systems and credit card numbers. SIMs are also capable of running applications (apps).

Nohl said Security Research Labs found mobile operators in many countries whose phones were vulnerable, but declined to identify them. He said mobile phone users in Africa could be among the most vulnerable because banking is widely done via mobile payment systems with credentials stored on SIMs.

All types of phones are vulnerable, including iPhones from Apple, phones that run Google’s Android software and BlackBerry smartphones, he said.

The International Rescue Committee (IRC) has announced the formation of Airbel Ventures, a new humanitarian impact investing fund aimed at accelerating the introduction and scaling of breakthrough technologies in crisis-affected communities.

The fund will invest in companies whose ideas have the potential to change humanitarian response, including digital infrastructure for frontline health systems and climate-resilient agriculture.

The launch of Airbel Ventures follows a period of rapid innovation at the IRC, despite the humanitarian sector facing record funding cuts.

In the past year, the IRC’s Airbel Impact Lab has advanced more than twenty Artificial Intelligence (AI) and technology initiatives—from anticipatory action tools powered by climate and vulnerability data, to frontline service delivery using safe, orchestrated AI systems, to breakthrough diagnostic tools for emerging diseases.

Airbel Ventures’ first impact investment is in Signalytic, a company delivering solar-powered computing devices that ensure reliable electricity and connectivity for remote health facilities.

Following the investment, the IRC will pilot Signalytic’s technology with its Nigeria Health team, demonstrating the viability of next-generation digital infrastructure in humanitarian settings.

“We know breakthrough solutions already exist—what’s missing is the path to scale in humanitarian contexts,” said Dr. Jeannie Annan, Senior Vice President for Research & Innovation at the IRC and head of the Airbel Impact Lab.

MTN Nigeria Suffers 9,218 Fibre Cuts in 2025 as Vandalism, Theft Cripple Network

MTN Nigeria, the country’s largest telecommunications operator, recorded a historic surge in network disruptions in 2025, suffering 9,218 fibre cuts as of December 31, alongside 211 base station sites affected by theft and vandalism, incidents that disrupted mobile and data services relied upon daily by millions of Nigerians.

MTN Nigeria Suffers 9,218 Fibre Cuts in 2025 as Vandalism, Theft Cripple Network

The data was revealed by Dr Karl Toriola, chief executive officer/managing director, MTN Nigeria via a social media post titled ‘MTN Nigeria 2025 Wrapped’.

The scale of the damage highlights the growing vulnerability of Nigeria’s telecommunications infrastructure, which has come under increasing pressure from road construction activities, cable theft and deliberate acts of vandalism.

MTN said 5,478 fibre cuts occurred within just the first seven months of 2025, with 760 incidents recorded in July alone, underscoring the intensity of the challenge.

Some of the incidents had wide-ranging consequences, knocking out connectivity across multiple states simultaneously and affecting voice calls, data services, digital payments and enterprise operations.

The company described the situation as a national infrastructure problem, rather than an isolated corporate issue, given the economy’s deep dependence on mobile networks.

“These gaps were shaped by real operational challenges such as fibre cuts, theft, and vandalism. Their impact is felt directly by customers and reflected in what they tell us,” Toriola,

The disruptions were reflected in customer feedback volumes, as MTN handled an unprecedented number of complaints during the year. The operator said it resolved 1,624,263 customer complaints in 2025, spanning call centres, social media platforms, emails and physical service centres nationwide.

Despite the setbacks, MTN pointed to signs of operational resilience. The company retained its ranking as Nigeria’s best network by Ookla, returned to profitability after a challenging period, declared an interim dividend, and expanded its subscriber base to over 85 million users by September 2025.

The figures show that while Nigeria’s telecom operators continue to invest heavily in network expansion and customer service, infrastructure sabotage remains a major drag on service quality and operating costs.

MTN acknowledged that performance improvements remain a work in progress. “We are not where we want to be yet. We see you. We hear you. We exist because of you. And we will get better,” Toriola said.

As the company enters its 25th year of operations in Nigeria, Toriola said MTN is doubling down on customer-centricity, treating every piece of feedback as a guide for improvement, while also stepping up engagement with government agencies.

The CEO renewed calls for stronger regulatory and legal protections for telecommunications infrastructure, urging policymakers to classify fibre cables, base stations and other critical assets as national infrastructure and criminalise vandalism to deter repeat attacks.

The newly licensed firms are Intellvision Technologies Limited, Granet Technologies Limited, Fiber Sonic Limited, Dasol Solution Services Ltd, Boost ISP Limited, and Amazon Kuiper Nigeria Limited.

Five of these companies are headquartered in Lagos, while Granet Technologies Limited operates from Owerri in Imo State, highlighting the persistent concentration of broadband infrastructure in major commercial hubs like Lagos, Abuja, and Port Harcourt.

This development intensifies competition in Nigeria’s broadband market, which faces pressure from dominant mobile network operators such as MTN and Airtel, alongside rapid expansion by satellite providers like Starlink.

Traditional ISPs continue to grapple with shrinking customer bases, aggressive data pricing from telcos, and satellite disruptions, even as NCC data from Q2 2025 showed Spectranet, Starlink, and FibreOne controlling about 65 per cent of the 313,713 active ISP subscribers.

The inclusion of Amazon Kuiper Nigeria Limited marks a significant entry of global satellite broadband competition, building on Nigeria’s recent approvals for other low Earth orbit providers to enhance connectivity in underserved areas.

Industry analysts view the licences as a strategic push to improve internet quality amid rising demand for digital services, though geographic clustering underscores ongoing infrastructure challenges outside urban centres.

NCC’s move aligns with broader efforts to foster a competitive telecoms sector critical to Nigeria’s digital economy ambitions.
