Abuse of Trust

Abuse of Trust refers to a cybersecurity attack where malicious actors exploit legitimate access privileges or relationships to compromise systems or data.

This type of attack leverages existing trust relationships—whether between users, systems, or organizations—to bypass security controls that would typically prevent unauthorized access.

Common examples include insider threats where employees misuse their legitimate system access, supply chain attacks where trusted vendors are compromised to reach target organizations, and credential theft where attackers use stolen legitimate credentials to appear as authorized users. These attacks are particularly dangerous because they often bypass perimeter security measures and may go undetected for extended periods.

Abuse of trust attacks can also involve social engineering tactics, where attackers manipulate trusted relationships to gain access to sensitive information or systems. For instance, an attacker might impersonate a trusted colleague or vendor to trick employees into providing access credentials or sensitive data.

Defending against abuse of trust requires implementing zero-trust security models, continuous monitoring of user behavior, regular access reviews, and strong authentication mechanisms. Organizations must also maintain clear policies regarding access privileges and regularly audit trust relationships with third-party vendors and partners.
