Experts Finger Insiders in Telcos for Rising SIM Swap Fraud

Published

Cyber security experts have berated telecommunications operators over the prevalence of SIM swap fraud in the country, arguing that such fraud could be possible with an insider in the network operator of the subscriber that is targeted.

 

SIM swapping is a sophisticated form of fraud and falls under social engineering. Fraudsters will distribute phishing emails, trying to ascertain as much personal information from victims as possible.

 

How it works

Your phone network will momentarily go blind without signal or Zero Bars and after a while a call will come through.

The person on the other side will tell you that he is calling from Airtel, MTN, 9mobile or Glo depending on your network and that there is a problem in your mobile network.

 

He will instruct you to Please press 1 on your phone to get the network back.

 

If you press 1, the network will appear suddenly and almost immediately go blind again (Zero Bars) and by that action, your phone is #HACKED.

 

It will appear as though your line is without network; meanwhile your SIM has been SWAPPED.

 

It is increasing by the day.  Within a second they will empty your bank account and cause you enough damage. The danger here is that; you will not get any alert of any transaction.

 

Responding to this Oluseyi Akindeinde, chief technical officer, Digital Encode, said that SIM swap is not new.

 

“A lot of the perpetrators have insiders in the telecommunications operator that allow them to do this. Nothing really can be done to check it unless they checkmate the guys inside the telcos,” he said.

 

William Makatiani, managing director, Serianu, said that SIM swap has become a lucrative enterprise in Africa particularly because of the increased adoption of mobile money services and mobile based authentication.

 

“Attackers gather enough information on a target such as ID details; Phone numbers etc through social engineering and create a false identity. Using this information, the attackers can contact the service provider and request for SIM card replacement and thereafter start transacting using your phone.

Tony Ojobo, director, Public affairs, Nigerian Communications Commission (NCC), acknowledged the existence of SIM Swap fraud and explained that it is a criminal act which is the responsibility of law enforcement agencies.

 

“SIM swap fraud is a criminal matter. What NCC investigate and sanction are issues around regulatory breaches and issues that contravenes terms of operators’ license. Just as if banks identify any of their staff that collude with fraudsters to perpetrate fund such persons are arrested and handed over to the police to prosecute and punish,” he said.

 

Apart from law enforcement agencies; Makatiani offered a number of ways to combat SIM fraud which includes; introducing additional checks for SIM reissuing such as security questions, avoid responding to unsolicited calls and text messages asking about your bank details.

 

Others are introducing user behavioral analysis (UBA) especially for financial institutions to monitor for key indicators of compromise and alert the customers as well as Adopting the IMSI (International Mobile Subscriber Identity) a unique number associated with a specific GSM phone to ensure one-time use codes are sent only to legitimate subscribers.

ATU, AFRINIC Urge Governments, Regulators to Develop Internet Resilience Framework

As Africa continues to face internet disruptions, telecom leaders have urged governments and regulators to embrace and implement a Model Framework for Building Regional Internet Resilience.

The African Telecommunications Union (ATU), Internet Society, and African Network Information Centre (AFRINIC) have all endorsed the framework.

The framework organises Africa’s internet resilience challenge around three interdependent focus areas: networks and internet service providers (ISPs), critical infrastructure such as power grids and cables, and market conditions that influence affordability and demand, according to the organisations in a joint statement.

Once implemented, entities or operators responsible for an important part of a country’s internet ecosystem, such as electricity utilities, mobile network operators, ISPs, internet exchange points, or a country-code top-level domain registry, must develop a resilience plan within one year of the framework’s official adoption.

The statement also mentions several past disruptions that hampered communication, such as the West Africa Cable System failure in March 2024, which cut off 13 countries for days.

They went on to explain that the plan must be evaluated and updated on an annual basis and be compatible with the entity or operator’s continuity and reconstitution plans.

It (framework) should also specify how the organisation intends to incorporate the resilience features of redundancy, resourcefulness, rapid recovery—all of which are critical components of achieving overall robustness—into its operations.

ATU has warned that every blackout is a flashing red warning, and that the framework would act as an insurance policy against outages.

“Connectivity remains Africa’s nervous system and when it stutters, schools, hospitals and markets stutter too. This framework is our insurance policy against digital darkness”, said John Omo, secretary general of ATU.

Arthur Carindal, AFRINIC’s head of stakeholder engagement, commended the institutions for their coordinated efforts.

He said: “It is a great honour for AFRINIC to collaborate with ATU and ISOC in transformative initiative enabling all stakeholders to participate in developing Africa’s internet resilience model framework, which highlights key policy recommendations and best practices for strengthening internet infrastructure in Africa.”

NCC Rallies Stakeholder Support to Protect Telecom Infrastructure

Nigerian Communications Commission (NCC) has reiterated its commitment to the full operationalisation of President Bola Ahmed Tinubu’s Executive Order on Critical National Information Infrastructure (CNII), which designates telecommunications facilities as critical national assets deserving optimal protection.

This comes on the heels of a successful mediation led by the Office of the National Security Adviser (ONSA), in collaboration with the Commission, which resulted in the suspension of a planned strike by the Natural Oil and Gas Suppliers Association of Nigeria (NOGASA).

The strike, if carried out, would have disrupted the supply of diesel to telecommunications sites nationwide, severely affecting network operators’ ability to power their diesel-driven generators and maintain uninterrupted connectivity.

In the days leading up to the resolution, the ONSA, under the leadership of the National Security Adviser (NSA), Mallam Nuhu Ribadu, held strategic engagements with NOGASA’s leadership, with the Commission providing technical and regulatory guidance to highlight the potential implications of service disruptions on national security, the economy, and everyday life.

The discussions culminated in an agreement to call off the industrial action, averting what could have been a nationwide disruption of telecom services.

“Telecommunications infrastructure is the backbone of our connectivity and digital economy. Any disruption, whether through vandalism, accidental damage during construction work, theft of equipment, denial of access to maintenance teams, or interruptions in the supply of essential operational materials, has far-reaching implications for service delivery, economic stability, and national security,” the NSA said.

The Commission expressed appreciation to the ONSA for its leadership and dedication to protecting national assets and commended the maturity and understanding demonstrated by relevant stakeholders in recognising the national importance of telecommunications services.

Commenting on the development, the Executive Vice Chairman/Chief Executive Officer of the Commission, Dr. Aminu Maida, stated: “We will continue to enforce strict compliance by our licensees with technical standards for the deployment and maintenance of telecommunications infrastructure, while working closely with relevant stakeholders to strengthen awareness and cooperation on their protection.

“We also recognise mediation as an effective tool for building consensus among stakeholders. This resolution underscores the importance of dialogue in preventing avoidable service disruptions. Ultimately, we call on all Nigerians to regard telecom infrastructure as a shared national asset, one that underpins our ability to connect with loved ones, transact businesses, access healthcare, pursue education, and participate in the global digital economy.”

The Commission reaffirmed that it would continue to coordinate with security agencies, industry stakeholders, and the public to ensure that Nigeria’s telecommunications infrastructure remains protected, resilient, and reliable for all.

Active internet subscriptions across mobile, fixed, and VOIP networks in Nigeria dropped to 141.1 million in June, representing a 0.3% decline from the 141.5 million recorded in May, according to the latest statistics from the Nigerian Communications Commission (NCC).

Mobile network operators MTN, Airtel, Globacom, and 9mobile maintained their dominance with a combined 140.6 million subscriptions, leaving Internet Service Providers and others with 528,633 subscriptions at the end of June.

Despite the slight drop in subscriptions, data consumption continued to grow. Nigerians used 1.044 million terabytes of data in June, marginally higher than the 1.043 million terabytes recorded in May, which had been the highest monthly usage since January 2023.

Telecom operators say this surge in data usage is driven by the rapid growth of Nigerian cities, especially Lagos, where more people, businesses, and devices are fueling record bandwidth consumption. In response, operators are expanding capacity to meet the rising demand.
