MITRE ATT&CK Enterprise TechniquesAI

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.
T1059.001 PowerShell Execution
Adversaries may abuse PowerShell commands and scripts for execution.
T1213.006 Databases Collection
Adversaries may leverage databases to mine valuable information.
T1565.003 Runtime Data Manipulation Impact
Adversaries may modify systems in order to manipulate the data as it is accessed and displayed to an end user, thus threatening the integrity of the data.
Why these techniques?

IDOR authz bypass directly enables unauthorized execution of graph runs (T1059.001), data reads from app repos (T1213.006), and message injection (T1565.003) against other tenants; maps to public app exploitation (T1190).
