Does use of an administrative tool prove malicious activity?¶

No. Administrative tools are designed to make powerful changes, and the same tool can be used legitimately in one session and maliciously in another. Its use is an event to explain, not a conclusion about intent.

The assessment should connect a particular invocation to an operator or automated job, its instructions, its targets and its effects.

Establish the organisation's normal use¶

Baseline evidence can show whether the organisation uses the tool, from which management servers, under which accounts and during what maintenance windows. This makes a deviation measurable rather than merely unusual in the investigator's experience.

Compare the event using features such as:

• source device and account;
• authentication or management session;
• command arguments, script or job identifier;
• parent and child processes;
• destination systems and data; and
• approval record and resulting changes.

A deployment utility launched from its usual server during an approved change may be routine. The same utility launched from a user workstation against new targets may require a different explanation, but still does not prove an offence without the wider evidence.

Avoid relying on appearance¶

An offender may copy, rename or execute a tool from an unusual path. Those facts can support analysis, but filenames and locations are readily changed. Conversely, the vendor's signed binary may execute unauthorised instructions exactly as designed.

Report the observed command and effect separately from any inference about purpose or personal control. An account name, by itself, identifies neither the person at the device nor who supplied an automated job.
