T1082 System Information Discovery Discovery
An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture.
attack.mitre.org →
T1016 System Network Configuration Discovery Discovery
Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of systems they access or through information discovery of remote systems.

Why these techniques?

Hard-coded SNMP credentials enable direct exploitation of an exposed network service (T1190) to extract device and network configuration details (T1082/T1016).

AC-9 Previous Logon Notification
addresses: CWE-798

Enables users to notice when hard-coded credentials have been exploited for unauthorized access.

AT-3 Role-based Training
addresses: CWE-798

Security training explicitly warns against hard-coded credentials, lowering their use in systems.

IA-1 Policy and Procedures
addresses: CWE-798

Policy and procedures prohibit hard-coded credentials in favor of managed authentication.

IA-13 Identity Providers and Authorization Servers
addresses: CWE-798

External identity providers eliminate the need for hard-coded credentials in applications.

IA-5 Authenticator Management
addresses: CWE-798

Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.

PL-9 Central Management
addresses: CWE-798

Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.

PM-16 Threat Awareness Program
addresses: CWE-798

Intelligence programs surface reports of campaigns that abuse hard-coded credentials in products, prompting removal or replacement and thereby reducing successful exploitation.

PM-3 Information Security and Privacy Resources
addresses: CWE-798

Planned investment enables secure credential storage and management systems instead of hard-coded credentials.
