Data from MITRE ATT&CK®:
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).
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(Citation: SANS Information Security Reading Room Securing SNMP Securing SNMP). The MIB may also contain device operational information, including running configuration, routing table, and interface details.
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.(Citation: US-CERT-TA18-106A)(Citation: Cisco Blog Legacy Device Attacks)

Mitigations for this technique
MITRE ATT&CK Mitigations
Network Intrusion Prevention
Use intrusion detection signatures to block traffic at network boundaries.Software Configuration
Implement configuration changes to software (other than the operating system) to mitigate security risks associated to how the software operates.Update Software
Perform regular software updates to mitigate exploitation risk.Network Segmentation
Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services...Encrypt Sensitive Information
Protect sensitive information with strong encryption.Filter Network Traffic
Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic.How to detect this technique
MITRE ATT&CK Data Components
Network Connection Creation (Network Traffic)
Initial construction of a network connection, such as capturing socket information with a source/destination IP and port(s) (ex: Windows EID 5156, Sysmon EID 3, or Zeek conn.log)Network Traffic Content (Network Traffic)
Logged network traffic data showing both protocol header and body values (ex: PCAP)SP800-53 Controls
See which controls can help protect against this MITRE ATT&CK technique. This is based on mappings to associated SP800-53 controls produced by the MITRE Engenuity Center for Threat-Informed Defense.
