Firefox Extensions

L0 Member

Hello guys, this is my first post, I'm glad I can be part of this community, I tried to make a query to see what extensions are installed in Firefox. I hope it is ok and useful and if you have something to add to improve it, I would be very happy.


config case_sensitive = true

| preset = xdr_file
| filter agent_os_type = AGENT_OS_WINDOWS
| filter event_sub_type = FILE_CREATE_NEW
| filter causality_actor_process_image_name = "firefox.exe"
| filter action_file_path contains "C:\Users\*\AppData\Roaming\Mozilla\Firefox\Profiles\*\extensions"
| filter action_file_name not contains "Zone.Identifier"
| alter action_file_name = split(action_file_name, "_")
| arrayexpand action_file_name
| filter action_file_name not contains "tmp"
| fields _time as Time, agent_hostname as Hostname, agent_ip_addresses as IPv4, actor_effective_username as User, action_file_name as extensionID, action_file_sha256
