Reproduce ADS creation in `System32\\Tasks` and capture DACL behavior.\n2. Trace `NtUserLoadKeyboardEx` with kernel debugger to identify read-access failure points.\n3. Hunt for similar overlooked trusted directories (e.g., `System32\\spool\\drivers`).\n4. Read the comment below for start.", "creation_timestamp": "2026-09-10T08:20:02.039014Z"}
