The objective of this repo is to share 100+ hunting queries (osquery) that will help cyber threat analysts (hunter/investigator) in their hunting or investigation exercises. Broadly, I have covered persistence, process interrogation, memory analysis, driver profiling, and other misc categories. Persistence and Process Interrogations queries map to the multiple tactics & techniques/sub-techniques of MITRE ATT&CK framework.

The following are the key highlights under each category. Please have a look at the repo(windows) for the details.

• Registry Run Keys / StartUp Folder
• RunKeys (with hashvalue)
• Security Support Provider
• Service Creation / Modification (auto_start)
• look for suspicious dlls loaded by any service (with associated username & hash value of the dll)
• WMI Event Consumers (commandline & script)
• WMI Process interrogation
• Application Shimming
• Print Processors - Reg Keys
• look for suspicious print drivers
• Screensaver Backdoor
• Image File Execution Options Injection (IFEO)(debugger/GolbalFlag)
• PowerShell Process Interrogation
• Dynamic Data Exchange (DDE)

• Identify the parent & Grantparent processes for all OR a given process - look for any suspicious parent, child relationships
• Identifying Suspicious Processes (processes) with usernames (users)
• Identifying the programs that are running from "TEMP" locations
• Identify the processes with open pipes (look for suspicious pipe and/or process)
• Any processes spawning out of wow64 directory
• Identifying suspicious dlls loaded by any service with user_account associated with it (with hash value)
• Identify if the binary is signed or not
• PowerShell Process Interrogation (Parent / children of PowerShell)
• WMI Process Interrogation (Parent / children of PowerShell)
• Identifying the excessive resources usage by a suspicious process - Excessive Memory Usage (In Bytes)
• Identifying the processes that makes the remote network connections and look for any suspicious connections

• pslist equivalent
• pstree equivalent ( Parent & Child)
• pstree equivalent ( Grandparent, Parent & Child)
• dlllist equivalent ( with a specific pid )
• dlllist - load all the dlls
• getsids - equivalent
• svcscan - equivalent
• netscan - equivalent
• Code Injection
• malfind (not exactly) equivalent

• Group By and Order By device_name
• Drivers without manufacturer name with sign status
• Unsigned drivers
• Drivers with no service associated with sign status

• File Profilig - Files with mtime<btime with hash values and sigcheck status in the critical directories
• Tracking User Changes
• look for any suspicious domain connection
• Execution (PS,DDE)
• Lateral Movement

Note: I will share "osquery.conf" file and queries related to Linux as I get some time to complete them.
