Executive Summary

IT service desks represent a growing security blind spot that threat actors increasingly exploit to bypass organizational security controls. By impersonating legitimate employees or end-users, attackers can manipulate helpdesk personnel into performing actions such as resetting credentials, granting elevated access, or disabling security features. This social engineering vector circumvents traditional security measures by exploiting trust placed in the service desk function. Organizations should implement strict verification procedures for service desk requests, including multi-channel authentication and enhanced staff training on social engineering tactics. Regular security awareness and red team exercises focused on service desk scenarios can help identify and remediate these vulnerabilities before they are exploited.

Summary

Could a simple call to the helpdesk enable threat actors to bypass your security controls? Here’s how your team can close a growing security gap.
