MFA Fatigue and Why Attackers Love It

Ever had your phone buzzing non-stop with MFA requests until you're tempted to just approve and make it stop? Well, attackers love this trick—it's called "MFA Fatigue", and it's one of their favorite tactics.

‍

Here's how it happens: attackers flood users with constant MFA prompts hoping the user eventually caves and clicks "Approve" just to stop the notifications. Sneaky, right?

CISOs Should Be Concerned

‍

MFA fatigue attacks represent a growing concern in our dynamic SaaS security landscape. While multi-factor authentication is meant to be a critical security layer, attackers have found ways to exploit human psychology to bypass it.

‍

The risks are substantial:

• Data Breaches: Once an attacker gains access through approved MFA, they can extract sensitive information or intellectual property
• Lateral Movement: Initial access can lead to privilege escalation and movement across your SaaS ecosystem
• Compliance Violations: Compromised accounts often lead to violations of regulatory requirements like SOC 2, ISO 27001, or GDPR
• Reputation Damage: Security incidents resulting from MFA fatigue can severely impact customer trust and brand reputation

Most concerning, these attacks target your SaaS identity infrastructure directly—the very foundation of your security posture in today's app-sprawling environment.

How Reco Handles MFA Fatigue

‍

We keep an eye out for signs you're being bombarded by MFA requests. Here's how:

• Declined MFA Requests: We watch for unusual spikes in MFA declines—multiple declines usually mean someone's trying to push their way in.
• Microsoft Blocking MFA Requests: If Microsoft itself steps in and blocks MFA prompts because someone went overboard, we'll notice and flag it immediately.
• Advanced Analytics: Reco's knowledge graph continuously crunches user behavior data, spotting patterns that indicate ongoing MFA fatigue attacks. If something looks suspicious, we'll spot it early and alert you ASAP.

Our Dynamic SaaS Security approach provides comprehensive protection against MFA fatigue attacks:

• Identity Threat Detection & Response (ITDR): Through our ITDR capabilities, Reco provides instant alerts on suspicious activities like MFA bombing campaigns.
• Contextual Intelligence: We don't just detect the attack—we provide rich context about the user, their role, the targeted applications, and potential business impact.
• Cross-App Visibility: Our platform monitors activity across your entire SaaS ecosystem, catching attempts that might target multiple applications simultaneously.
• Automated Response: Reco can trigger automatic remediation workflows through your existing security tools, stopping attacks before they succeed.

Reco's advanced analytics engine identifies suspicious patterns by analyzing:

• Activity originating from categorized high-risk IP addresses
• Unusual timing or frequency of authentication attempts
• Geographic anomalies compared to normal user behavior
• Sequential failed attempts across multiple applications
• Potential account lockouts or blocking actions by identity providers

All of this intelligence is presented in a comprehensive dashboard that gives security teams full visibility into potential MFA fatigue campaigns.
