MITRE ATT&CK Enterprise Techniques

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.
T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
T1608.001 Upload Malware Resource Development
Adversaries may upload malware to third-party or adversary controlled infrastructure to make it accessible during targeting.
T1608.002 Upload Tool Resource Development
Adversaries may upload tools to third-party or adversary controlled infrastructure to make it accessible during targeting.
Why these techniques?

Unrestricted file upload in public-facing web application (T1190) enables staging of malware/tools (T1608.001, T1608.002) and deployment of web shells for execution/persistence (T1100, T1505.003), leading to RCE.
