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
