<p>Adversaries may target the Management Information Base (MIB) to collect and/or mine valuable information in a network managed using Simple Network Management Protocol (SNMP).</p><p>The MIB is a configuration repository that stores variable information accessible via SNMP in the form of object identifiers (OID). Each OID identifies a variable that can be read or set and permits active management tasks, such as configuration changes, through remote modification of these variables. SNMP can give administrators great insight in their systems, such as, system information, description of hardware, physical location, and software packages. The MIB may also contain device operational information, including running configuration, routing table, and interface details.</p><p>Adversaries may use SNMP queries to collect MIB content directly from SNMP-managed devices in order to collect network information that allows the adversary to build network maps and facilitate future targeted exploitation.</p>

None. No KEV entry in the public mapping names this technique. Given that 74.7% of KEV has no mapping at all, this says more about the mapping than about the technique.
Detection strategy · ATT&CK Enterprise v19.2
- DET0453 Detection Strategy for SNMP (MIB Dump) on Network Devices v1.0
AN1249 Network DevicesDefenders may observe suspicious SNMP MIB enumeration through abnormal queries for large sets of OIDs, repeated SNMP GETBULK/GETNEXT requests, or queries originating from non-administrative IP addresses. Anomalous use of community strings, authentication failures, or enumeration activity outside maintenance windows may also indicate attempts to dump MIB contents. Correlation across syslog, NetFlow, and SNMP audit data can reveal chains of behavior such as repeated authentication failures followed by successful large-scale OID retrieval.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.
