Investigation guide
edit## Config If enabling an EQL rule on a non-elastic-agent index (such as beats) for versions <8.2, events will not define `event.ingested` and default fallback for EQL rules was not added until 8.2, so you will need to add a custom pipeline to populate `event.ingested` to @timestamp for this rule to work.
Rule query
editprocess where event.type in ("start", "process_started") and process.args : ( "/Users/*/Library/Application Support/Google/Chrome/Default/Login Data", "/Users/*/Library/Application Support/Google/Chrome/Default/Cookies", "/Users/*/Library/Cookies*", "/Users/*/Library/Application Support/Firefox/Profiles/*.default/cookies.sqlite", "/Users/*/Library/Application Support/Firefox/Profiles/*.default/key*.db", "/Users/*/Library/Application Support/Firefox/Profiles/*.default/logins.json", "Login Data", "Cookies.binarycookies", "key4.db", "key3.db", "logins.json", "cookies.sqlite" )
