Mongodb Driver Handshake And Topology Recon

Client performs structured MongoDB deployment reconnaissance by first initiating a standard driver handshake (ismaster / hello) disclosing client runtime and platform metadata (PyMongo, CPython, Linux x86_64), followed by an advanced topology-aware handshake request against the admin database including topologyVersion tracking and long-poll await semantics. This sequence reflects automated driver-level service validation and replica-set / cluster state discovery activity commonly associated with scanning frameworks, monitoring tooling, or pre-enumeration reconnaissance workflows preparing for deeper database interaction.
