title: 'Suspicious history file operations'
id: eae8ce9f-bde9-47a6-8e79-f20d18419910
status: experimental
description: 'Detects commandline operations on shell history files'
# Rule detects presence of various shell history files in process commandline
# Normally user expected to view own history with dedicated 'history' command and not some other tools
# There is a possibility for rule to trigger, when T1070.003 techinuque is used (history file cleared)
# For this rule to work execve auditing must be configured
# Example config (place it at the bottom of audit.rules)
# -a always,exit -F arch=b32 -S execve -k execve
# -a always,exit -F arch=b64 -S execve -k execve
