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.”
Google has unveiled a new feature that allows Gmail users to change their existing email addresses without losing data or access to services, marking a major shift in the company’s long-standing policy.
Gmail
According to an update on Google’s account help page, the new option enables account holders to replace their current @gmail.com address with a new one while retaining all associated data, including emails, photos, and integrations with services such as Google Drive, Maps, and YouTube.
The guidance, however, was first spotted on the Hindi version of Google’s support page, suggesting that the rollout may begin in India or Hindi-speaking markets before expanding globally.
The English-language support page still carries the older advisory that Gmail addresses “usually cannot be changed.”
Google explained that under the new policy, users who update their Gmail address will automatically keep their original address as an alias.
This means emails sent to the old address will continue to arrive in the inbox, and the original address will remain valid for signing in to Google services.
Previously, users seeking a new Gmail address had to create an entirely new account and manually transfer their data, a process that often disrupted third-party app integrations. The new feature eliminates that inconvenience, ensuring continuity for users.
The company further clarified that while users can reuse their old Gmail address at any time, accounts that change their address will face certain restrictions.
These include a 12-month waiting period before another new Gmail address can be created, and the inability to delete the newly chosen address once it has been set.
Google assured users that all existing data would remain intact after an address update, including stored photos, messages, and emails.
The gradual rollout of the feature indicates that full global adoption is expected in the coming months, a move likely to be welcomed by millions of users who have long requested the ability to update their Gmail identities without starting afresh.
Nigerian Communications Commission (NCC) has said that Nigeria’s internet usage reached a record 1.24 million terabytes in November 2025.
According to the latest data from the NCC, the figure rose modestly from 1.235 million terabytes in October, reflecting steady growth in digital activity across the country.
Broadband penetration in Nigeria crossed the halfway mark in November 2025, reaching 50.58 per cent, up from 45.61 per cent in January, the telecoms regulator reported.
The figure, however, falls short of the 70 per cent coverage target outlined in the National Broadband Plan 2020–2025, which expires this month.
The country had roughly 109 million broadband subscriptions by November. Growth has been uneven, hindered by infrastructure and regulatory constraints, including frequent fibre-optic vandalism that triggers 30 to 43 network cuts daily, high right-of-way fees, and declining subscriber numbers earlier in the year.
Expansion of mobile networks, particularly 3G and 4G services, alongside limited 5G rollouts in urban centres, affordable smartphones, and competitive data plans, has driven uptake.
Investments in the National Communications Backbone and private-sector initiatives have also improved access, especially in underserved areas.
While Nigeria is gradually improving digital inclusion, achieving the original broadband plan remains challenging due to high infrastructure costs, coverage limitations, and deployment hurdles.
The NCC maintains that continued investment in mobile networks and broadband infrastructure will sustain gradual growth in the sector.
Commenting on the development, some Nigerian analysts attributed the surge to the broader mobile and broadband adoption and the growing appetite for streaming, online learning and other digital services.
According to the analysts, the figures suggest that internet connectivity is no longer a luxury but a necessity for both business and leisure, underscoring the slow but steady expansion of Nigeria’s digital economy.
Bureau of Public Service Reforms (BPSR) has named the Nigerian Communications Commission (NCC) among the top three Ministries, Departments and Agencies (MDAs) of the Federal Government with the Best Ranking in Website Performance for 2025.
L-R: Head Special Projects, Nigerian Export Promotion Council (NEPC), Salamatu Andu; Executive Commissioner, Technical Services, Nigerian Communication Commission (NCC), Engr. Abaraham Oshadame; Director General Bureau of Public Service Reforms (BPSR), Head Customer Support Service, Galaxy Backbone, Rosemary Ehize; Secretary to the ES. Nigerian Content Development and Monitoring Board, Tahir Aminu at the BPSR award ceremony for top four MDAs in BPSR Website Performance and Ranking 2025 at the BPSR office on Tuesday, 23rd December, 2025.
This is coming barely three weeks after the telecom regulator was recognized as one of the top five best-performing Federal Government agencies for 2025 by the Presidential Enabling Business Environment Council (PEBEC) – a testament to the Commission’s consistency in investment in technology for ensuring efficient service delivery.
In the BPSR 2024/2025 scorecard ranking of agencies’ websites, the NCC came second in the ranking, trailing behind Galaxy Backbone Limited, which came first while the Nigeria Export Promotion Council (NEPC) clinched the third position, from a pool of 235 MDAs, whose website were evaluated.
BPSR deployed 14 evaluation criteria in include MDA’s website compliance with .gov.ng domain name, appearance and aesthetics (look and feel) of the website, content, relevance to MDAs mandate/government policy and the website’ structure.
Others include website’s responsiveness (device compatibility), security, load time, usability/ease of navigation, availability/uptime, functionality, interactivity, accessibility and capacity building.
The recognition was announced at the official release of Federal Government 2024/2025 Scorecard Ranking for MDAs’ Website held at the Federal Ministry of Finance Auditorium in Abuja on Monday (December 22, 2025) while the award presentation took place at BPSR’s Office on Tuesday (December 23, 2025).
The award, which is an important index metric of the National e-Government Masterplan for determining the Nigeria e-Government Status, was received by the Commission in recognition of its commitment to maintaining a world-class website that enhances service delivery to the citizens.
Receiving the award on behalf of the Executive Vice Chairman of the NCC, Dr. Aminu Maida, the NCC’s Executive Commissioner, Technical Services, Abraham Oshadami, appreciated the BPSR for the recognition, describing the award as “another encouragement for the Commission to be a better public service institution leveraging digital platforms such as our web presence to enhance public service delivery to our various stakeholders, thereby implementing the Federal Government’s Ease of Doing Business policy direction.”
While presenting the award to the NCC, alongside other two agencies, BPSR’s Director-General, Mr. Dasuki Arabi, commended the top three for their proactive decisions in maintaining world-class websites, which are compliant with the Federal Government’s policy direction in effective and efficient service delivery to the citizens.
According to the DG, the 2024/2025 MDA’s websites’ ranking represents a collective effort of federal public institutions in Nigeria to be transparent, accountable and open in governance, as well as a confirmation to align with global best practices in service delivery to the citizens.
Developed about six years ago, Arabi said as a result of the annual ranking, more public institutions have indicated readiness to embrace reforms, and align with the policy direction of the current administration’s Renewed Hope agenda on improve governance for effective service delivery, as introduced by His Excellency President Bola Ahmed Tinubu.
“The ideals of harnessing and deploying technological tools for service delivery has become imperative following the COVID pandemic, and distortions of socio-economic system of nations, culminating in the evolution of competitiveness, cost effectiveness, and agile governance.
“As engine room of governance, it behoves on us in the public service to perform our statutory duties and we must put in place technological innovations and standardized websites to operate services as well as deliver service needs to citizens,” he said.
The Scorecard exercise, he said, is part of the BPSR reform broader function of conducting research on reform implementation efforts and presenting ‘best practice’ models to the entire Public Service, and to among others, improve access to government information, facilitate seamless financial transaction, eliminate corruption and cyber theft, as well as facilitate access to government services.
Speaking on the rigorous nature of the exercise that produced the top three winners, the DG said “in the past few weeks members of the Scorecard Jury drawn from inter-Ministerial Agencies, had worked tirelessly to mill websites of selected MDAs through a rigorous process of enduring criteria for the ranking and the outcome had also passed through a quality assurance mechanism to validate the outcome.”
