services / Azure / Private DNS A record set
An A record set maps internal hostnames to IPv4 addresses within an Azure Private DNS zone, used for name resolution inside linked virtual networks.
Private (internal) records, not public-facing; supports a single organizational network function.
Microsoft.Network/privateDnsZones/A/write
Creating/updating the record set replaces internal hostname-to-IP mappings, letting an attacker repoint internal names to attacker-controlled IPs to route/intercept traffic (DNS hijack within the private zone).
Risks
Scope: HIGH
