<p>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. By manipulating runtime data, adversaries may attempt to affect a business process, organizational understanding, and decision making.</p><p>Adversaries may alter application binaries used to display data in order to cause runtime manipulations. Adversaries may also conduct Change Default File Association and Masquerading to cause a similar effect. The type of modification and the impact it will have depends on the target application and process as well as the goals and objectives of the adversary. For complex systems, an adversary would likely need special expertise and possibly access to specialized software related to the system that would typically be gained through a prolonged information gathering campaign in order to have the desired impact.</p>

Sigma rules · SigmaHQ da9bb07d64, tag attack.t1565.003
No Sigma rule carries this tag. MITRE publishes a detection strategy above, so the behaviour is specified; what is missing is public detection content.

Detects powershell scripts that adds a Name Resolution Policy Table (NRPT) rule for the specified namespace.
This will bypass the default DNS server and uses a specified server for answering the query.
