{ "description": "Targeted System Access Control Lists (SACLs) that make Object Access File System (4663), Registry (4657) and Handle Manipulation (4656/4658) auditing produce the events the Hayabusa/Sigma Security-channel rules rely on - WITHOUT enabling global file/registry auditing (which would flood). Only the specific autostart/persistence registry keys (ASEPs) and sensitive files referenced by the ruleset are audited. Principal is 'Everyone'. Registry keys use ContainerInherit so subkeys are covered. Objects that are absent on a given host (e.g. Wow6432Node on 32-bit, NTDS on non-DCs) are skipped. Per-user objects are handled via 'user_registry' and 'user_files': WELA enumerates every profile from ProfileList (plus C:\\Users\\Default so future users inherit the SACL), sets file SACLs under each profile, and sets registry SACLs on each user hive (loaded hives directly via HKU:\\, offline/Default hives by reg-load/unload of NTUSER.DAT). 'user_registry' keys are relative to the user hive root; 'user_files' paths are relative to the profile directory. Remaining edge cases (folder-redirected AppData on network shares, mandatory profiles) are not covered.", "registry": [ { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP Run (T1547.001)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunOnce", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP RunOnce" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunOnceEx", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP RunOnceEx" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunServices", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP RunServices" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunServicesOnce", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP RunServicesOnce" }, { "path": "HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Run", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP Run (WOW64)" }, { "path": "HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\RunOnce", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP RunOnce (WOW64)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer\\Run", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "ASEP Policies Explorer Run" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "Winlogon Shell/Userinit/Notify (T1547.004)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Image File Execution Options", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "IFEO debugger/GlobalFlag (T1546.012)" }, { "path": "HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows NT\\CurrentVersion\\Image File Execution Options", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "IFEO (WOW64)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Windows", "inherit": false, "rights": [ "SetValue" ], "note": "AppInit_DLLs / Load / Run (T1546.010)" }, { "path": "HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows NT\\CurrentVersion\\Windows", "inherit": false, "rights": [ "SetValue" ], "note": "AppInit_DLLs (WOW64)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\ShellServiceObjectDelayLoad", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "SSODL (T1547.005)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\SharedTaskScheduler", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "SharedTaskScheduler" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\ShellIconOverlayIdentifiers", "inherit": true, "rights": [ "CreateSubKey", "Delete" ], "note": "ShellIconOverlayIdentifiers" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Browser Helper Objects", "inherit": true, "rights": [ "CreateSubKey", "Delete" ], "note": "BHO (T1176)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Active Setup\\Installed Components", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "Active Setup (T1547.014)" }, { "path": "HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\Active Setup\\Installed Components", "inherit": true, "rights": [ "SetValue", "CreateSubKey", "Delete" ], "note": "Active Setup (WOW64)" }, { "path": "HKLM:\\SOFTWARE\\Microsoft\\Command Processor", "inherit": false, "rights": [ "SetValue" ], "note": "cmd AutoRun (T1546.011)" }, { "path": "HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\Command Processor", "inherit": false, "rights": [ "SetValue" ], "note": "cmd AutoRun (WOW64)" }, { "path": "HKLM:\\SYSTEM\\CurrentControlSet\\Control\\Session Manager", "inherit": false, "rights": [ "SetValue" ], "note": "BootExecute/AppCertDlls/SubSystems (T1546.009)" }, { "path": "HKLM:\\SYSTEM\\CurrentControlSet\\Control\\Lsa", "inherit": false, "rights": [ "SetValue" ], "note": "LSA Security/Authentication/Notification Packages -
