<p>Adversaries may access network configuration files to collect sensitive data about the device and the network. The network configuration is a file containing parameters that determine the operation of the device. The device typically stores an in-memory copy of the configuration while operating, and a separate configuration on non-volatile storage to load after device reset. Adversaries can inspect the configuration files to reveal information about the target network and its layout, the network device and its software, or identifying legitimate accounts and credentials for later use.</p><p>Adversaries can use common management tools and protocols, such as Simple Network Management Protocol (SNMP) and Smart Install (SMI), to access network configuration files. These tools may be used to query specific data from a configuration repository or configure the device to export the configuration for later analysis.</p>

Detection strategy · ATT&CK Enterprise v19.2
- DET0233 Detection Strategy for Network Device Configuration Dump via Config Repositories v1.0
AN0647 Network DevicesDefenders may observe adversary attempts to collect or export full device configurations by detecting unusual SNMP queries, Smart Install (SMI) activity, or CLI/API commands that request running or startup configuration dumps. Correlated behaviors include high-volume read requests for sensitive OIDs, repeated use of 'show running-config' or equivalent commands from untrusted IPs, or unexpected TFTP/SCP/FTP transfers containing configuration files. These behaviors often appear in sequence: anomalous authentication or privilege escalation, followed by bulk configuration retrieval and outbound transfer.networkdevice:syslog

No Sigma rule carries this tag. MITRE publishes a detection strategy above, so the behaviour is specified; what is missing is public detection content.
