Picture this: You’re enjoying a quiet evening when your phone buzzes. It’s a push notification asking you to approve a login. Odd—you’re not trying to log in anywhere. A few minutes later, another notification pops up, then another. Before long, you’re overwhelmed with requests, and out of frustration, you approve one just to make it stop. Congratulations, you’ve just fallen victim to an MFA fatigue attack—a devious tactic that cybercriminals use to bypass your defenses.
In 2022, MFA fatigue attacks were linked to high-profile breaches, including the infamous Uber hack where attackers bombarded employees with MFA notifications until someone caved. It’s a simple trick, but the damage it can cause is anything but. So how do these attacks work, and more importantly, how can you prevent them?
This blog is your guide to understanding MFA fatigue attacks, why they’re so dangerous, and how you can prevent them from happening to your business.
An MFA fatigue attack—also known as MFA bombing—is a type of identity-based attack where hackers exploit multi-factor authentication systems by sending repeated push notifications to the victim’s device. The goal? To coerce the victim into confirming their identity by wearing them down with relentless authentication requests.
Hackers thrive on human error and fatigue. According to a 2023 cybersecurity report by Verizon, 74% of breaches involved the human element, including phishing, stolen credentials, or errors (Verizon DBIR). This attack method plays on human psychology, making even robust MFA systems vulnerable.
Understanding how these attacks operate is critical to protecting against them. Here’s a breakdown of the process:
These attacks are frighteningly effective, leveraging human behavior instead of complex technical exploits. They take advantage of a simple truth: people make mistakes when stressed, annoyed, or tired.
Here’s the hard truth: 70% of data breaches are caused by compromised passwords or identity-based attacks (source). That’s not just an IT issue; it’s a business problem with massive implications.
A single approved MFA notification can lead to:
The September 2022 Uber breach cost the company millions—not just in immediate damages but also in long-term trust and reputation.
Could your business survive such a blow?
It’s not always easy to spot an MFA fatigue attack in progress, but there are telltale signs:
If any of these red flags appear, it’s time to act quickly.
Prevention starts with smarter strategies and better tools. Here’s what you can do:
Modern MFA solutions offer adaptive authentication, analyzing the context of each login attempt (e.g., location, device, time). If something looks suspicious, access is denied automatically—no repeated MFA requests needed.
Human error is the biggest vulnerability in cybersecurity. Invest in user education to teach your employees how to recognize and respond to suspicious MFA prompts.
Follow these best practices to minimize risk:
Set up alerts for repeated login attempts or multiple failed authentications. A strong security information and event management (SIEM) system can help detect these attack patterns in real time.
Not every employee needs access to every system. Enforce role-based access management to limit potential damage if an account is compromised.
Partner with experts who can deploy multi-layered security solutions tailored to your business. Prevention is always cheaper—and less painful—than recovery.
Think of cybersecurity as a seatbelt: you hope you’ll never need it, but you’ll be grateful it’s there when you do. Ignoring threats like MFA fatigue attacks is like driving without a seatbelt—you’re betting your business won’t crash.
But here’s the reality: 60% of small businesses that suffer a cyberattack shut down within six months. Can you afford to take that gamble?
Preventing MFA fatigue attacks and other identity-based threats requires a proactive approach. Without proper expertise, your business risks being exposed to unauthorized access, data breaches, and operational disruptions.
The good news? You’re not alone in this fight. By combining robust technology, well-trained employees, and expert guidance, you can build defenses strong enough to keep attackers out. And that’s where we come in. Our team specializes in securing businesses like yours with advanced MFA solutions, user education, and 24/7 monitoring to ensure you’re always one step ahead of attackers.
The time to act is now. Your business deserves more than reactive measures—it deserves proactive security that evolves with the threats you face. Don’t wait until a successful attack forces you to pick up the pieces. Let’s stop the fatigue before it starts.

MFA fatigue attacks, also known as MFA bombing, occur when threat actors overwhelm users with multiple multi-factor authentication requests in an attempt to gain unauthorized access. This can lead to users becoming desensitized to the notifications, increasing the risk of successful login attempts by attackers.
To prevent MFA fatigue attacks, security teams should implement measures such as rate limiting the number of MFA requests, educating users about social engineering tactics, and encouraging the use of strong, unique login credentials. Training on MFA best practices can also help users recognize potential phishing attacks.
SMS codes, authentication apps, biometric scans, and hardware tokens are examples of MFA methods. Combining these methods can enhance security and reduce the risk of unauthorized access.
Social engineering tactics are often employed by attackers to manipulate users into providing their login credentials or to trick them into approving unauthorized MFA requests. Awareness of these tactics can help users better protect themselves against identity-based attacks.
If you receive unexpected MFA requests, do not authenticate them. Instead, immediately change your login credentials and report the incident to your security team. This can help mitigate the risk of unauthorized access due to potential MFA fatigue attacks.
Attackers may use malware to automate the process of sending MFA requests, leading to MFA fatigue. When users become overwhelmed by constant notifications, they may inadvertently approve a request from a hacker, compromising their accounts.
Training on MFA can equip employees with the knowledge to recognize potential MFA attacks and understand how to authenticate safely. It can also raise security awareness about the risks associated with MFA fatigue and other types of attacks that may target their accounts.
The MITRE ATT&CK framework is a comprehensive knowledge base that outlines various tactics and techniques used by attackers. It can help security teams understand the methods employed in MFA attacks, including MFA bombing, so they can better prepare and defend against them.
Yes, using multiple types of MFA can significantly enhance security. For instance, combining something you know (like a password) with something you have (like a hardware token) can create a layered defense against potential MFA fatigue attacks.
Not using MFA increases the risk of unauthorized access to sensitive accounts and data. Attackers can exploit weak passwords through brute-force or phishing attacks, making it crucial to implement multi-factor authentication as a security measure.
