MITRE ATT&CK Enterprise TechniquesAI

T1046 Network Service Discovery Discovery
Adversaries may attempt to get a listing of services running on remote hosts and local network infrastructure devices, including those that may be vulnerable to remote software exploitation.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

The SSRF vulnerability (CWE-918) in Misskey APIs enables exploitation of a public-facing application (T1190) and facilitates internal network service discovery (T1046) by allowing low-privileged attackers to send HTTP requests to private IPs.
