File Basic Information is a Windows file information class that stores core metadata such as creation time, last access time, last write time, and file attributes. It is used when querying or setting basic timestamps and attributes on a file object.
What File Basic Information Does
File Basic Information is a Windows file information class used to read or update the core metadata attached to a file object. In practice, it carries the timestamps and attributes that Windows uses to describe when a file was created, last accessed, or last written, along with basic file flags.
Because these fields sit at the centre of file metadata handling, the class is important whenever software needs to inspect file history, preserve timestamps during legitimate maintenance, or make attribute changes without rewriting file contents. It is a low-level interface, so small mistakes can alter investigative evidence or application behaviour.
Why This Metadata Matters
These values are more than bookkeeping. Creation, access, and write times are often used by backup tools, indexers, security products, and forensic workflows to establish file age, activity, and sequence. File attributes can also influence how the operating system and applications treat a file, such as whether it is marked hidden, read-only, or otherwise special.
That makes the information class useful, but also sensitive. A program that updates metadata can change how the file appears in audits, timelines, synchronisation jobs, or compliance checks. In investigations, even a legitimate metadata write may need to be explained because it can resemble tampering.
Common Uses and Interpretation
Most callers use File Basic Information to query metadata before deciding whether a file needs to be touched, copied, archived, or compared. The class gives a compact snapshot of state that is easier to consume than parsing higher-level file system records.
It is also used when an application intentionally preserves or normalises metadata. For example, migration and restoration tools may need to carry timestamps forward, while administrative utilities may change attributes without editing the file body. The meaning of the fields is straightforward, but the operational consequences are not always simple, because later tools may trust those values as part of a workflow.
Operational and Security Implications
When metadata can be modified, defenders have to treat timestamps and attributes as potentially useful signals rather than absolute proof of history. File metadata can be altered by ordinary software, by administrative actions, or by malicious activity that aims to disguise execution, copying, staging, or cleanup. Forensics teams therefore compare this class with other file system artefacts instead of relying on it alone.
The class also matters in environments where change tracking is part of security monitoring. A benign maintenance job can create noise, while hostile metadata changes can help hide activity. File System Forensics Guide is useful here because it explains how to compare these timestamps and attributes with MFT records, journals, and timeline evidence. Anti-Forensics Detection Guide shows why timestomping and related artefact manipulation deserve specific scrutiny. Forensic Timeline Analysis Guide adds the broader timeline context needed to interpret those values correctly.
Risk and Threat Considerations
File Basic Information becomes risky when systems or investigators treat its timestamps as inherently trustworthy. Metadata can be rewritten without touching file contents, so an attacker or careless operator may create a misleading history that obscures execution, staging, or exfiltration activity.
Failure mechanism: A process with sufficient file write capability updates timestamps or attributes to match an expected timeline, reducing the value of the metadata as a standalone indicator.
Impact: Security teams may miss tampering, misorder events in an investigation, or draw the wrong conclusion about when a file appeared or changed.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
MITRE ATT&CK addresses the attack surface, CIS Controls v8 and NIST SP 800-53 Rev 5 set the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| MITRE ATT&CK | T1070.006 — Timestomp | Metadata timestamp manipulation is the core anti-forensics behaviour this term exposes. |
| Recommendation — Map abnormal file metadata changes to T1070.006 and correlate them with surrounding process activity. | ||
| CIS Controls v8 | CIS-8 — Audit Log Management | File timestamp and attribute abuse is best validated against durable audit evidence and log integrity. |
| Recommendation — Preserve and review audit trails that can corroborate or contradict file metadata changes. | ||
| NIST SP 800-53 Rev 5 | AU-6 — Audit Review, Analysis, and Reporting | Correlating file metadata with logs and other artefacts is an audit analysis problem. |
| SI-4 — System Monitoring | Monitoring is needed to detect suspicious file changes and metadata tampering patterns. | |
| Recommendation — Analyze audit data alongside file metadata to confirm or refute suspicious timestamp changes. Monitor for file metadata anomalies and alert on suspicious write or attribute changes. | ||
| ISO/IEC 27001:2022 | A.8.16 — Monitoring activities | Monitoring file metadata changes supports detection of suspicious or unauthorised activity. |
| Recommendation — Define monitoring for file attribute and timestamp anomalies within operational logging. | ||
Practitioner Guidance
What to watch for: Use this metadata as one evidence source, not as a final answer. When timestamps look abnormal, compare them with journal data, directory records, file hash history, and process or audit logs before deciding whether the file is genuine, copied, restored, or manipulated.
Governance implication: If software or scripts are allowed to set file metadata, define when that behaviour is legitimate and make sure investigators know which maintenance tools can create expected timestamp changes. That reduces false positives without blinding the team to real tampering.
