In the ever-evolving landscape of cybersecurity, Multi-Factor Authentication (MFA) has emerged as a robust defense mechanism, adding layers of security beyond traditional passwords. However, a deceptive tactic known as “push-bombing” is undermining this very safeguard, posing significant risks to individuals and organisations alike.
Understanding Push-Bombing
Push-bombing, also referred to as MFA fatigue or MFA spamming, is a social engineering attack that targets the human element of security systems. Attackers initiate this method by obtaining a user’s login credentials, often through phishing or data breaches. Subsequently, they attempt to access the account, triggering a barrage of authentication prompts sent to the user’s device. The relentless stream of notifications aims to confuse or frustrate the user into inadvertently approving one, thereby granting unauthorised access to the attacker.
Real-World Implications
The consequences of successful push-bombing attacks are far-reaching. Once inside a system, attackers can exfiltrate sensitive data, deploy malware, or move laterally within networks to compromise additional systems. Such breaches not only result in financial losses but also damage an organisation’s reputation and can lead to regulatory penalties.
