Malicious hackers are targeting Office 365 users with a spare of ‘MFA fatigue attacks’, bombarding victims with 2FA push notifications to trick them into authenticating their login attempts.
This is according to researchers from GoSecure, who have warned that there is an increase in attacks that are exploiting human behavior to gain access to devices.
Multi-factor authentication (MFA) fatigue is the name given to a technique used by adversaries to flood a user’s authentication app with push notifications in the hope they will accept and therefore enable an attacker to gain entry to an account or device.
In a blog posted earlier this week, GoSecure described the attack as “simple”, given that “it only requires the attacker to manually, or even automatically, send repeated push notifications while trying to log into the victim’s account”.
