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.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
Why these techniques?

T1190 for exploiting the public-facing WordPress theme vulnerability (LFI via improper filename control in PHP include/require). T1005 for reading arbitrary local files remotely, enabling data collection from the local system.
