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.
attack.mitre.org →
Why these techniques?

The LFI vulnerability in the public-facing WordPress theme directly enables exploitation of a public-facing application (T1190) and facilitates collection of data from arbitrary local system files via improper filename control in PHP include/require (T1005).
