Use all three artifacts together for conclusive analysis.\n\n## Prerequisites\n\n- A forensic image or live triage copy of `C:\\Windows\\appcompat\\Programs\\Amcache.hve` (and associated `.LOG1`, `.LOG2` transaction logs)\n- Eric Zimmerman's AmcacheParser (`AmcacheParser.exe`) downloaded from https:\u002F\u002Fericzimmerman.github.io\u002F\n- Eric Zimmerman's Timeline Explorer for viewing parsed CSV output\n- Optionally: Registry Explorer for manual hive inspection\n- A SHA-1 whitelist of known-good executables (e.g., NSRL hashset) for filtering\n- .NET 6+ runtime installed (required by current EZ tools)\n- Write access to an output directory for CSV results\n\n## Workflow\n\n### Step 1: Acquire the Amcache.hve File\n\nExtract the Amcache hive from a forensic image or live system:\n\n```powershell\n# From a live system (requires elevated privileges and raw copy tool)\n# Amcache.hve is locked by the system; use a raw disk copy tool\n# Option A: FTK Imager - mount image and navigate to:\n# C:\\Windows\\appcompat\\Programs\\Amcache.hve\n# Also collect: Amcache.hve.LOG1, Amcache.hve.LOG2\n\n# Option B: Using KAPE for automated triage collection\nkape.exe --tsource C: --tdest D:\\Evidence\\%m --target Amcache\n\n# Option C: From a mounted forensic image (E: = mounted image)\ncopy \"E:\\Windows\\appcompat\\Programs\\Amcache.hve\" D:\\Evidence\\\ncopy \"E:\\Windows\\appcompat\\Programs\\Amcache.hve.LOG1\" D:\\Evidence\\\ncopy \"E:\\Windows\\appcompat\\Programs\\Amcache.hve.LOG2\" D:\\Evidence\\\n```\n\nAlways collect the transaction log files (`.LOG1`, `.LOG2`) alongside the hive. AmcacheParser replays uncommitted transactions from these logs to recover the most complete data.\n\n### Step 2: Parse Amcache with AmcacheParser\n\nRun AmcacheParser against the acquired hive:\n\n```powershell\n# Basic parsing with CSV output\nAmcacheParser.exe -f \"D:\\Evidence\\Amcache.hve\" --csv \"D:\\Evidence\\Output\"\n\n# Parse with a SHA-1 whitelist to exclude known-good entries (NSRL)\nAmcacheParser.exe -f \"D:\\Evidence\\Amcache.hve\" -w \"D:\\Whitelists\\nsrl_sha1.txt\" --csv \"D:\\Evidence\\Output\"\n\n# Parse with a SHA-1 inclusion list (only show matches against known-bad hashes)\nAmcacheParser.exe -f \"D:\\Evidence\\Amcache.hve\" -b \"D:\\IOCs\\malware_sha1.txt\" --csv \"D:\\Evidence\\Output\"\n\n# Include deleted entries with high-precision timestamps\nAmcacheParser.exe -f \"D:\\Evidence\\Amcache.hve\" --csv \"D:\\Evidence\\Output\" -i --mp\n```\n\nAmcacheParser produces multiple CSV files in the output directory:\n\n| Output File | Contents |\n|-------------|----------|\n| `Amcache_AssociatedFileEntries.csv` | File entries with SHA-1 hashes, paths, sizes, and timestamps |\n| `Amcache_UnassociatedFileEntries.csv` | Orphaned file entries from older Amcache format |\n| `Amcache_ProgramEntries.csv` | Installed program metadata (name, publisher, version, install date) |\n| `Amcache_DeviceContainers.csv` | USB and device connection history |\n| `Amcache_DevicePnps.csv` | Plug-and-Play device driver information |\n| `Amcache_DriverBinaries.csv` | Loaded driver binaries with paths and hashes |\n\n### Step 3: Analyze File Entries for Suspicious Programs\n\nOpen the `AssociatedFileEntries.csv` in Timeline Explorer and examine key columns:\n\n```\nKey columns to review:\n- ProgramId          : Links file to its parent program entry\n- SHA1               : Hash for threat intel lookups\n- FullPath           : Original file location on disk\n- FileSize           : Size of the executable\n- FileKeyLastWriteTimestamp : When the Amcache entry was last updated\n- Name               : File name\n- Publisher           : Code signing publisher (blank = unsigned)\n- BinProductVersion  : Version string from the PE header\n- LinkDate           : PE compilation timestamp (useful for detecting timestomping)\n```\n\nFilter for suspicious indicators:\n\n```\n# In Timeline Explorer, apply these filters:\n\n# 1.
