Network Mapping for Attacks
Bad actors can map your entire correspondent banking network topology (who connects to whom) to identify weak links, target less sophisticated banks for social engineering, and impersonate specific banks more convincingly.
Authentication required to view relationship connections prevents attackers from obtaining complete network topology, making relationship mapping incomplete and social engineering attacks less targeted.
Business Email Compromise (BEC) Enhancement
BEC attacks become dramatically more effective when attackers have contact lists with names, email addresses, and phone numbers, allowing them to create highly convincing fake emails referencing real relationships and operational staff.
Member-only access and granular authorization controls prevent bulk contact harvesting. Contact details are only available to authenticated member institutions with proper access permissions, making contact list compilation for BEC attacks extremely difficult.
Insider Threat Amplification
Disgruntled employees can more easily facilitate fraud when they know the complete network map and can provide attackers with exact correspondent relationships to exploit.
Authentication requirements create audit trails and limit the pool of individuals with access to sensitive contact details, reducing insider threat vectors.
