Basic search to find Log4J running on hosts from the DataLake

Basic search which lists processes that include log4j in the cmdline> on Windows, Mac and Linux. The query returns a lot of results but works for an insight into what's running on the estate.

SELECT
meta_hostname AS ep_name,
name,
cmdline,
path,
query_name,
sophos_pid,
pid
FROM xdr_data
WHERE query_name IN( 'running_processes_linux_events', 'running_processes_osx_events', 'running_processes_windows_sophos')
AND LOWER(cmdline) LIKE '%log4j%'

    User "HulkHogan" opened this PDF "TLPGREEN_CYIM-21-028.1_UPDATE_Log4j Vulnerability Exploited in the Wild_20211213.pdf" with the Microsoft Edge Browser (msedge.exe). Since the XDR query looks for literally anything containing the string "log4j" it will also show these instances
