What evidence may show when persistence was created?¶

The most reliable creation time comes from correlating the event that made the mechanism appear with filesystem, configuration, account and process records. One timestamp rarely supplies the whole answer.

Find the causal event¶

Account, task, service, consent, extension and upload logs may directly record creation. Process telemetry, commands and administrative audit events can identify the account or process responsible and the surrounding session.

Filesystem metadata can support the sequence, but a timestamp may describe copying or later modification. Imported tasks, restored images and deployment systems can reproduce older values, while an offender may deliberately alter them.

Align clocks and coverage¶

Preserve original time zones, clock drift and the recording rules of each source. Also establish when logging began and its retention: absence before a date may mean the source did not exist, not that persistence was created later.

Use immediately preceding and following activity to form a supported window where no single creation event survives. That window may still connect the mechanism to a remote session, exploit or account. It does not by itself identify the person controlling that activity.
