description: This search is to detect a suspicious file creation of sqlite3.dll in
|
|
%temp% folder. This behavior was seen in IcedID malware where it download sqlite
|
|
module to parse browser database like for chrome or firefox to stole browser information
|
|
related to bank, credit card or credentials.
|
|
data_source:
|
|
- Sysmon Event ID 1
|
|
search: '`sysmon` EventCode=11 (TargetFilename = "*\\sqlite32.dll" OR TargetFilename
|
|
= "*\\sqlite64.dll") (TargetFilename = "*\\temp\\*")
|
|
| stats count min(_time) as
|
|
firstTime max(_time) as lastTime by dest signature signature_id process_name file_name file_path action process_guid| `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)`
|
|
| `sqlite_module_in_temp_folder_filter`'
|
|
how_to_implement: To successfully implement this search, you need to be ingesting
|
|
logs with the process name, parent process, and command-line executions from your
|
|
endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the
|
|
Sysmon TA.
