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.
Nigeria has exactly 156,662 active fixed wired internet subscriptions as of mid-2026.
This is a tiny fraction compared to mobile GSM networks, which dominate the market with over 154 million subscribers.
The fixed wired market primarily consists of homes and offices using direct physical cables like fiber optics.
Fixed wired services use physical cables, like glass fiber or copper wire, to bring internet directly into a building.
It is like a dedicated, private water pipe for your home. It provides very fast speeds, unlimited data, and is reliable.
In contrast, mobile GSM uses radio waves transmitted from tall towers to phones, acting more like a sprinkler that sprays a signal across an entire neighborhood.
Because laying physical cables across cities is expensive and hard to do, these subscriptions are very rare.
However, the market has seen recent growth, driven largely by Fiber-to-the-Home (FTTH) services.
The top players are: MTN FibreX with 110,564 subscribers, which is roughly 88.7 per cent of the entire market.
SWIFTNG accounts for about 13,945 connections.
The others are ipNX and 21st Century Technologies which make up the number.
Nigerian Communications Commission (NCC) says it is intensifying efforts to implement Nigeria’s planned 112 national emergency number following its approval by the National Economic Council (NEC).

The commission disclosed this during a meeting between Vice President Kashim Shettima and an NCC delegation led by the Chairman of its Governing Board, Chief Idris Ibikunle Olorunnimbe, at the Presidential Villa, Abuja.
Briefing the Vice President, Olorunnimbe said the NCC had already established about 35 Emergency Communications Centres (ECCs) across the country to support a unified national emergency response system.
He said the next phase of implementation would focus on closer collaboration with state governments and emergency response agencies to ensure the effective rollout of the initiative.
The development follows the recent approval by the NEC, chaired by the Vice President, for the adoption of 112 as Nigeria’s single national emergency number across all tiers of government and emergency response agencies.
The council also approved the establishment of a multi-agency implementation committee to be jointly coordinated by the Office of the Vice President and the NCC.
Olorunnimbe stressed that the success of the initiative would depend on the commitment of state governments to support and maintain emergency communications infrastructure, as well as the readiness of response agencies to promptly attend to distress calls.
“We need commitment at every level of all response agencies—from top to bottom—including the Nigeria Police Force, ambulance services across the states and, at the national level, the National Emergency Management Agency (NEMA),” he said.
Responding, Shettima directed the NCC to develop a comprehensive roadmap for the nationwide implementation of the single emergency number in line with international best practices.
He also urged the commission to work closely with the National Emergency Management Agency (NEMA), citing the agency’s experience in disaster management, relief and rehabilitation.
The Vice President assured the commission of the Federal Government’s commitment to sustaining the initiative, saying funding would be mobilised through the National Economic Council and partnerships with the private sector.
He also called for greater dedication from all emergency response agencies to ensure the success of the programme.
The adoption of 112 is expected to harmonise emergency communications across Nigeria by providing a single number through which citizens can quickly access police, fire, ambulance and other emergency services.
The initiative is also expected to replace multiple emergency contact numbers currently in use and improve coordination and response during emergencies.
Nigerian Communications Commission (NCC) has said that it was strengthening collaboration with state governments and industry players to develop a transparent, cost-based pricing framework for sharing telecom ducts as part of efforts to speed up broadband expansion across Nigeria.
Ayuba Shuaibu, director of Policy, Competition and Economic Analysis, NCC, disclosed this at the Stakeholders’ Forum in Abuja.
Shuaibu said the initiative was designed to build consensus among all parties.
“The primary purpose of this forum is to ensure seamless synergy between the Commission and all stakeholders,” he said.
The director said the consultation was prompted by longstanding complaints over permits, levies and other charges imposed by different levels of government.
He said bringing together state commissioners, telecom operators, tower companies and representatives of the Nigeria Governors’ Forum had helped improve understanding of the issues.
“This engagement is a work in progress. We expect more input from stakeholders before presenting the outcome to the Nigeria Governors’ Forum,” he added.
Dr Helen Adeneye, commissioner for Innovation, Science and Technology, Kogi State. welcomed the consultation, saying Nigeria needs a harmonised policy that clearly defines the responsibilities of both the federal and state governments.
“We need a harmonised policy that allows states to collaborate better with telecom operators and creates a more business-friendly environment,” she said.
Dr Adeneye added that adopting the Dig-Once policy would establish a uniform pricing system and help resolve disputes over charges for telecom infrastructure deployment.
Chidi Ajuzie, chief executive officer, WTES Projects Limited, whose firm is conducting the consultancy study, said the proposed framework would introduce a common cost structure for duct sharing to support broadband investment and economic growth.
“The study is designed to create a uniform pricing model that will drive broadband growth, economic development and wider adoption across the country,” he said.
Ajuzie explained that the consultants had developed preliminary floor and ceiling prices to guide operators while allowing flexibility within the approved range.
He added that the recommendations remain open to industry input before the NCC finalises the framework.
The Dig-Once Policy is designed to reduce the cost and disruption of deploying broadband infrastructure by requiring fibre ducts to be installed whenever roads are constructed or rehabilitated.
The NCC is developing a cost-based pricing framework for sharing these ducts to promote fair pricing, reduce duplication of infrastructure and encourage investment.
The proposed model is expected to support the Federal Government’s broadband expansion targets while improving collaboration between telecom operators and state governments.
