The following rule detects attempts to tamper with Linux log records by looking for interpreter processes, or common utility commands interacting with critical log files such as /var/log/wtmp, /var/log/btmp, or /var/run/utmp. It also includes scenarios where 'dd' or 'cp' might be used with /dev/null or /dev/zero to effectively clear or overwrite log content.
