Initial Confidence and Impact is set by the analytic author. The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Associated Analytic StoryĪn instance of $parent_process_name$ spawning $process_name$ was identified on endpoint $dest$ by user $dest_user_id$ attempting to download a file. Limited false positives, however it may be required to filter based on parent process name or network connection. In addition, confirm the latest CIM App 4.20 or higher is installed and the latest TA for the endpoint product. To successfully implement this search you need to be ingesting information on process that include the name of the process responsible for the changes from your endpoints into the Endpoint datamodel in the Processes node. List of fields required to use this analytic. It allows the user to filter out any results (false positives) without editing the SPL. Windows_bitsadmin_download_file_filter is a empty macro by default. | where like(process_cmd_line, "%transfer%") AND process_file_name="bitsadmin.exe" -finding_report. | eval device_hostname=ucast(map_get(device,"hostname"), "string", null) | eval device=ucast(map_get(input_event,"device"), "map", null) | eval actor_process_file_name=ucast(map_get(actor_process_file,"name"), "string", null) | eval actor_process_file_path=ucast(map_get(actor_process_file,"path"), "string", null) | eval actor_process_file=ucast(map_get(actor_process,"file"), "map", null) | eval actor_process_pid=ucast(map_get(actor_process,"pid"), "string", null) | eval actor_process=ucast(map_get(actor,"process"), "map", null) | eval actor_user_name=ucast(map_get(actor_user,"name"), "string", null) | eval actor_user=ucast(map_get(actor,"user"), "map", null) | eval actor=ucast(map_get(input_event,"actor"), "map", null) | eval process_cmd_line=ucast(map_get(process,"cmd_line"), "string", null) | eval process_file_name=ucast(map_get(process_file,"name"), "string", null) ![]() | eval process_file_path=ucast(map_get(process_file,"path"), "string", null) | eval process_file=ucast(map_get(process,"file"), "map", null) | eval process_pid=ucast(map_get(process,"pid"), "string", null) | eval process=ucast(map_get(input_event,"process"), "map", null) | eval metadata_uid = ucast(map_get(metadata, "uid"),"string", null) | eval metadata = ucast(map_get(input_event, "metadata"),"map", null) ![]() | eval timestamp = ucast(map_get(input_event,"time"),"long", null) You can use bitsadmin /list /verbose to list out the jobs during investigation. In some suspicious and malicious instances, BITS jobs will be created. It's important to review all parallel and child processes to capture any behaviors and artifacts. Note that the network connection or file modification events related will not spawn or create from bitsadmin.exe, but the artifacts will appear in a parallel process of svchost.exe with a command-line similar to svchost.exe -k netsvcs -s BITS. Typically once executed, a follow on command will be used to execute the dropped file. Review the reputation of the IP or domain used. In addition, look for download or upload on the command-line, the switches are not required to perform a transfer. The following query identifies Microsoft Background Intelligent Transfer Service utility bitsadmin.exe using the transfer parameter to download a remote object.
