What You Need to Know About Multifactor Authentication Fatigue Attacks and How they can be Prevented

Multifactor authentication is a security measure that requires users to provide a second form of verification before they can log into a corporate network. It has long been considered essential for keeping fraudsters out. However, cybercriminals have been discovering increasingly clever ways to bypass it.
During an attack on Uber’s IT systems in 2022, the hackers did not use any sophisticated tactics to gain access. Instead, they bombarded an employee with repeated login requests until, out of sheer frustration, the employee approved one.
This type of cyberattack is known as an “MFA fatigue attack” and poses a real risk to organisations, says Anna Collard, SVP Content Strategy and Evangelist at KnowBe4 AFRICA, a cybersecurity training designer.
“MFA fatigue attacks, also known as prompt spamming or authentication bombing, exploit human vulnerability, rather than relying on high-tech hacking methods,” she explains. “These attacks involve sending continuous push notifications to a target who has already provided their username and password, aiming to irritate or confuse them into unwittingly granting the attacker access to their account or system.”
With Uber, the attacker likely bought the contractor’s Uber corporate username and password on the dark web. The attacker then made repeated attempts to log into the victim’s Uber account. Each time, the victim received a request to approve a two-factor login, which blocked access at first. However, eventually, and after the attacker contacted the contractor on WhatsApp claiming they were from Uber IT and that the only way to get rid of the never ending notifications was to accept one, the contractor accepted one request, allowing the attacker to successfully log in.
Previously, cybersecurity experts believed that Multifactor Authentication (MFA) was a foolproof method to protect corporate IT systems from hackers. “Now we’re seeing attackers finding ways around it by bombarding the victim with scores of MFA requests or by tricking them over the phone,” says Collard. This tactic, similar to a swarm of bees overwhelming someone, is a simple yet effective social engineering technique used by hackers. “By bugging you repeatedly until you give in, malicious actors can manipulate users into approving fraudulent access attempts,” says Collard.
How can you prevent it?
The best way to prevent MFA fatigue attacks in organisations is not to use push notifications. “While MFA provides an extra layer of security, it’s not foolproof,” she asserts. “From a cybersecurity perspective, I would recommend that organisations disable push notifications altogether and rather use alternative verification methods.”
An example of a better verification method is number matching. “This involves matching a unique code provided by the authentication app with the code displayed on the screen during the login process,” explains Collard.
A challenge-response method is another effective way of providing additional security. This method asks a user a specific question to verify their identity or to perform a task in response to a challenge. “A challenge-response method is more difficult for hackers to bypass. It can involve mechanisms like biometric authentication, in which users must scan their fingerprints or irises or use facial recognition to gain access to a network.” However, both of the above are not immune against so-called man in the middle or social engineering attacks tricking the users to hand over their OTP or response to the fraudster.
Another effective verification method is FIDO2, an open authentication standard that allows users to log in without using passwords. “You can implement FIDO2 using hardware security keys,” she explains. Typically, USB sticks store the user’s private key, while the public key is stored on the authentication server. As soon as the user enters their username and password, the system requests them to use the hardware key. “It is more resistant to phishing as it works on a challenge-response protocol and doesn’t rely on a one-time PIN that can be intercepted,” she adds.
Mindfulness is key
As with all hacking attempts, it’s crucial that users remain calm and mindful, rather than reacting emotionally. “Stay tuned into your body’s responses when dealing with potential cybersecurity threats, whether they are phishing emails or MFA fatigue attacks,” says Collard. “If something feels strange, like if the situation is putting you under undue pressure, listen to that cue and don’t respond in a knee-jerk fashion. In this way, you’ll keep a straight head and thwart potential data breaches.”

NCC, REA Move to Power Telecoms with Renewable Energy

Nigerian Communications Commission (NCC) and Rural Electrification Agency (REA) have teamed up to develop an initiative that will reduce the $350 million annual spending on diesel by telecom operators in Nigeria.
According to a press statement by Nnenna Ukoha, acting had of Public Affairs, NCC, this collaboration will focus on deploying renewable energy solutions to support telecom infrastructure, particularly in rural and underserved areas.
To that end, the two agencies have inaugurated what they called NCC–REA Collaboration Committee, aimed at deploying renewable energy solutions to power telecom infrastructure across the country.
According to the State of Africa’s Infrastructure Report 2025 by the Africa Finance Corporation, telecom operators in Nigeria consume more than 40 million litres of diesel every month, costing them over $350 million annually.
The statement read, “The Nigerian Communications Commission has formally inaugurated the NCC–REA Collaboration Committee, marking a pivotal step towards advancing Nigeria’s digital and energy inclusion objectives by developing modalities for the deployment of renewable energy to support telecom infrastructure in Nigeria.”
The inauguration ceremony, held on Friday, at the NCC Headquarters in Abuja, was presided over by Dr Aminu Maida, executive vice chairman and chief executive officer, NCC.
Maida was joined by Abba Aliyu, managing director of the REA, along with senior executives and committee members from both organisations.
Speaking at the event, Maida described the collaboration as a timely and strategic alignment of national priorities.
He noted that bridging the connectivity and power gaps in rural areas remains critical for Nigeria’s growth and development.
He highlighted that the demand for digital services and connected communities creates an opportunity for renewable energy to play a crucial role.
Maida further emphasised that the partnership goes beyond infrastructure; it is aimed at driving inclusion, reducing inequalities, and fostering shared prosperity.
“Whether it is powering a base station or enabling a child to access digital learning, this partnership has the potential to transform realities and bring opportunity closer to the people.
“This initiative is about more than infrastructure, it is about driving inclusion, bridging inequalities and creating the conditions for shared prosperity,” he was quoted in the statement.
He also noted that the initiative aligns with President Bola Tinubu’s Renewed Hope Agenda, which aims to ensure no community is left behind in Nigeria’s energy and digital transformation.
Aliyu, representing REA, expressed confidence in the transformative potential of the collaboration.
“This partnership will unlock sustainable development opportunities for millions of Nigerians, especially those in areas lacking traditional infrastructure,” he said.
He further emphasised that the collaboration would address both energy and connectivity gaps, benefiting those who are currently underserved.
The newly established NCC-REA Collaboration Committee will work to co-develop and implement integrated solutions that leverage renewable energy to power telecom sites.
The statement noted that the committee will also focus on sharing geospatial data to improve planning, aligning funding frameworks, and tracking the socio-economic impact of the project through clear performance indicators.

Don’t Visit Telecom Centers for Now — ALTON Warns of SIM Service Downtime

Association of Licensed Telecommunications Operators of Nigeria (ALTON) has announced a temporary disruption in SIM-related services across all mobile networks in the country.
The disruption, according to a statement on Wednesday, follows a directive from the National Identity Management Commission (NIMC), mandating mobile network operators (MNOs) to migrate to a new identity verification platform.
ALTON said the transition had triggered unforeseen technical challenges, affecting services such as SIM registration, replacement, and mobile number portability.
“While the new platform is intended to enhance the integrity and efficiency of identity management in Nigeria, unfortunately, the transition has temporarily impacted service delivery,” the association stated.
It added that MNOs would not be able to support SIM swaps, new activations, and related services until the issues are resolved.
ALTON noted that its members are working closely with the Nigerian Communications Commission (NCC), NIMC, and other stakeholders to restore normalcy.
The association appealed for public understanding and urged subscribers to delay visits to service centers for SIM-related matters.
“We sincerely apologise for the inconvenience and will continue to provide timely updates,” the statement read.
ALTON reaffirmed its commitment to delivering secure and quality telecommunications services to Nigerians.
