T1070.002: Clear Linux or Mac System Logs
Adversaries may clear system logs to hide evidence of an intrusion. macOS and Linux both keep track of system or user-initiated actions via system logs. The majority of native system logging is stored under the /var/log/ directory. Subfolders in this directory categorize logs by their related functions, such as:[1]
* /var/log/messages:: General and system-related messages * /var/log/secure or /var/log/auth.log: Authentication logs * /var/log/utmp or /var/log/wtmp: Login records * /var/log/kern.log: Kernel logs * /var/log/cron.log: Crond logs * /var/log/maillog: Mail server logs * /var/log/httpd/: Web server access and error logs
This ATT&CK object is revoked or deprecated in the current MITRE ATT&CK release.
It remains available for historical context and inbound links. Use current ATT&CK relationships and replacement guidance before basing detection or reporting work on this page.
Analyst summary pending validation
Glexia publishes ATT&CK takes only after source-hash and schema validation. Until then, use the official MITRE definition below and the defensive relationship context on this page.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.
Related techniques
This mirrors the MITRE pattern of making group, software, campaign, and technique relationships scannable. Relationship notes come from mirrored ATT&CK relationship text when available.

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates .
Imported snapshots across ATT&CK releases (1)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|
| 19.1 | 1.0 | Current bundle Revoked | fb8f7db66a3c… |
Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
