Passware Kit Forensic 202121 Winpe Boot L 2021 |top| -

The Passware Kit Forensic (PKF) 2021.2.1 release includes advanced features for encrypted evidence discovery, with a major focus on its bootable tools and full disk decryption. Key Features of the 2021.2.1 Release

Dell Encryption Support: This version is the first to decrypt disks encrypted with Dell Data Protection and Dell Encryption, provided a recovery file is available.

Hardware Benchmark Tool: A built-in utility to measure the performance of your CPUs and GPUs on typical recovery tasks like MS Office, Zip, and BitLocker.

GPU Acceleration: Faster recovery for Android 4.4 images (using scrypt) and significantly improved speeds for Zip archives (up to 13x faster).

Attack Usability: New ability to view and export the exact settings of successful attacks to reuse on other files. Passware Bootable Memory Imager

A standout component of the 2021 series is the Passware Bootable Memory Imager, a UEFI-compatible tool designed for "warm-boot" memory acquisition. passware kit forensic 202121 winpe boot l 2021

Function: It runs from a bootable USB drive to acquire live memory (RAM) images from Windows, Linux, and Mac systems.

Secure Boot Compatibility: It is specifically designed to work with systems where Secure Boot is enabled by using a "Shim UEFI" key management process.

Forensic Utility: Acquiring memory via warm-boot allows investigators to extract encryption keys for BitLocker, TrueCrypt, VeraCrypt, and APFS/FileVault2 volumes that were mounted at the time of seizure. Creating and Using the Bootable Tool

To use the bootable features, you must first prepare a USB drive from within the main application:

Prepare the USB: Launch Passware Kit Forensic as an administrator, click Memory Analysis, and follow the prompts to create the Memory Imager USB. The Passware Kit Forensic (PKF) 2021

Target Boot: Connect the USB to the target machine and perform a warm boot (using the hardware reset button) to prevent the RAM from clearing.

MOK Management: On Secure Boot systems, you may need to "Enroll hash from disk" (specifically the grubx64.efi file) in the Shim UEFI screen to authorize the boot loader.

Analysis: Once the image is acquired, use the Full Disk Encryption or Memory Analysis tabs in PKF to search for passwords and encryption keys within the captured segments.

Why "2021" Still Matters Today

While newer versions of Passware (2024, 2025) exist, the 202121 WinPE Boot L remains a relevant tool for specific scenarios:

• Legacy Case Backlog: Many cold cases from 2020-2022 involve Windows 10 builds that play perfectly with 202121's drivers.
• Stability: Some practitioners report that newer WinPE builds are heavier and occasionally crash on older hardware (DDR3-era). The 2021 "L" is lighter and faster on Core 2nd/3rd gen machines.
• Cost/Licensing: Organizations with perpetual licenses from 2021 cannot upgrade; this version remains their most robust offline boot disk.

However, be aware of limitations in 2021: It does not support TPM 2.0 + PIN BitLocker unlock via boot capture (requires the OS to be running), nor does it handle Apple M1/M2 Macs (x86 WinPE can't boot them).

12) Troubleshooting common issues

• Passware fails to run: check missing DLLs, Visual C++ runtimes may be required — include the correct VC++ redistributable or necessary runtimes in WinPE.
• Hardware not detected: add vendor SATA/NVMe drivers via DISM.
• License activation issues: perform vendor-recommended offline activation before deployment.
• GPU not available: ensure appropriate GPU drivers and CUDA/OpenCL runtimes are added to WinPE (this may be complex; alternative is to perform cracking on a separate GPU workstation using images).

Forensic Soundness Considerations

Using Passware Kit Forensic 202121 WinPE Boot L is not without controversy. Any time you boot a suspect computer via your own media, you alter the system's last access timestamps and potentially the registry’s last boot time.

Best practices:

• Image the hard drive first using a hardware imager.
• Only use the WinPE boot disk if RAM capture is essential for encryption keys.
• Document every key press and the exact time of booting.
• Use a write-blocker between the USB and the target's internal drive? Not possible, since the system must write to the registry minimally. Instead, rely on Passware’s own logging that writes to the external USB only.

3) Create base WinPE

1. Launch "Deployment and Imaging Tools Environment" as Administrator.
2. Create working copy:
   • For x64: copype amd64 C:\WinPE_amd64
   • For x86: copype x86 C:\WinPE_x86
3. Mount boot.wim if you plan to add files manually.

10) Password recovery best practices (Passware-specific)

• Prefer forensic images rather than live disk manipulation.
• Collect hibernation file (hiberfile.sys), pagefile, and system registry hives (SAM, SYSTEM, SECURITY) for Windows offline password extraction.
• For encrypted volumes (BitLocker), capture full metadata; attempt recovery with known keys or Passware’s recovery methods.
• Use GPU-equipped workstation for faster brute-force/metadata attacks; record GPU details and settings.
• Keep wordlists, rules, masks documented and repeatable; save session state to resume long runs.

Requirements

• Licensed Passware Kit Forensic 2021 installer and valid activation key.
• Windows 10/11 machine for building WinPE.
• Windows ADK for Windows 10/11 (WinPE add-on) matching your target environment.
• Sufficient disk space (≥20 GB recommended).
• USB flash drive (≥16 GB) or ISO burner.
• Target-system imaging/storage drive with capacity to hold full disk image.
• Optional: Forensic write-blocker, external HDD.
• Administrative privileges on build machine.
• Hashing tool (e.g., HashCalc, certutil) for verification.
• Forensics documentation template.
