Account Recovery Abuse

An Account Recovery Abuse attack exploits legitimate password reset and account recovery mechanisms to gain unauthorized access to user accounts.

Attackers leverage weaknesses in how organizations verify user identity during account recovery processes, often bypassing normal authentication controls.

Common techniques include exploiting insufficient identity verification during password resets, manipulating security questions with publicly available information, intercepting recovery emails or SMS messages, or using social engineering to convince support staff to reset account credentials. Attackers may also abuse backup email addresses or phone numbers they have previously compromised.

These attacks are particularly dangerous because they appear to use legitimate system functions, making them harder to detect and often bypassing security monitoring focused on login attempts. Organizations with weak identity verification processes, overly helpful customer service policies, or inadequate logging of recovery activities are especially vulnerable.

Effective defenses include implementing multi-factor authentication for recovery processes, requiring multiple forms of identity verification, limiting recovery attempts, monitoring unusual recovery patterns, training support staff on social engineering tactics, and maintaining detailed logs of all account recovery activities. Regular audits of recovery procedures can help identify and close potential abuse vectors.
