2026 Quick-Reference Cheat Sheet & Benchmark Table: Evil Maid Attack, TPM 2.0 PCR & LUKS2/BitLocker Planner

Quick Answer & 2026 Technical Summary (luks2 argon2id bitlocker tpm planner)Updated 2026 Standard

Coined by Joanna Rutkowska, an Evil Maid attack occurs when an adversary gains brief unattended physical access to a powered-off device (e.g., in a hotel room). In traditional Linux setups, the `/boot` partition (containing the kernel and initramfs that prompt for your LUKS password) is unencrypted. The attacker replaces the initramfs with a trojanized version that logs your passphrase on the next boot. Use this interactive luks2 argon2id bitlocker tpm planner above to test evil maid attack simulator, tpm 2.0 pcr register calculator, and systemd cryptenroll tpm2 luks2 guide locally in your browser with zero server uploads.

How to Use Evil Maid Attack, TPM 2.0 PCR & LUKS2/BitLocker Planner

Select Your OS Stack & Physical Threat Profile

Choose Linux (LUKS2 + systemd-boot/UKI) or Windows (BitLocker) and configure your current boot architecture (Separate unencrypted /boot vs. Signed UKI, TPM-Only vs. TPM+PIN).

Toggle TPM 2.0 PCR Banks (PCR 0 through PCR 15)

Select which PCR registers seal your volume encryption key (e.g., PCR 7 Secure Boot + PCR 11 UKI + PCR 14 MOK) and inspect the calculated hex PCR mask.

Tune LUKS2 Argon2id Memory & Iteration Hardness

Set your system RAM allocation (e.g., 1 GiB to 4 GiB PBKDF memory cost) to defend offline disk images against ASIC/GPU cracking.

Run the Evil Maid Attack Simulation & Copy Hardening CLI

Review the pass/fail status across all 6 physical attack scenarios and copy the generated `cryptsetup`, `systemd-cryptenroll`, `sbctl`, or `manage-bde` commands.

Key Capabilities & Technical Architecture

Interactive TPM 2.0 PCR (0–15) Boot Measurement Matrix

Select specific Platform Configuration Registers (PCR 0 UEFI firmware, PCR 4 Boot Loader/UKI, PCR 7 Secure Boot Policy, PCR 11 Unified Kernel Image) to compute the PCR bitmask and see which physical attacks each register blocks.

Evil Maid & Cold-Boot Attack Vector Simulator

Test your laptop's configuration against 6 physical threat models: Initramfs `/boot` Backdoor, SPI Flash / BootHole Modification, TPM LPC/SPI Bus Sniffing, DMA Thunderbolt/PCIe, and RAM Cold-Boot.

LUKS2 Argon2id Memory-Hard PBKDF Tuner

Calculate optimal `cryptsetup luksFormat --type luks2 --pbkdf argon2id` memory cost (`--pbkdf-memory`), parallel lanes, and target iteration milliseconds based on your system RAM.

Copy-Ready systemd-cryptenroll, sbctl UKI & BitLocker Commands

Generate exact CLI provisioning scripts for Linux Unified Kernel Images (UKI + Secure Boot custom keys + TPM2 PIN) and Windows BitLocker (`manage-bde` TPM+PIN with DMA lockdown).

Practical Use Cases

Executive Travel & Hotel-Room Laptop Hardening

Eliminate the classic 'Evil Maid' vulnerability where an attacker modifies an unencrypted Linux `/boot` partition or sniffs a headless TPM-only auto-unlock key on the SPI bus.

Linux Unified Kernel Image (UKI) & TPM2 Provisioning

Design a brittle-free TPM 2.0 enrollment strategy using PCR 7 (Secure Boot state) + PCR 11 (signed UKI measurement) + pre-boot PIN so firmware updates don't brick boot unnecessarily.

Enterprise Windows 11 BitLocker Compliance Auditing

Verify why standard TPM-only BitLocker is vulnerable to physical SPI bus logic analyzers unless Pre-Boot PIN (`TPMandPIN`), Enhanced PINs, and Kernel DMA Protection are enforced.

Frequently Asked Questions (FAQs)

What is an Evil Maid attack and why doesn't standard Full Disk Encryption stop it?+

How does a Unified Kernel Image (UKI) + Secure Boot + TPM 2.0 defeat Evil Maid?+

A Unified Kernel Image bundles the Linux kernel, initramfs, and kernel command line into a single PE binary signed with your personal Secure Boot key (`sbctl`). During boot, UEFI verifies the signature (measured into PCR 7) and measures the UKI into PCR 11. If an attacker alters `/boot` or kernel parameters (`init=/bin/sh`), the PCR hash changes and the TPM 2.0 chip refuses to unseal the LUKS2 volume key.

Why is 'TPM-Only' automatic disk unlock vulnerable to a $50 logic analyzer?+

When BitLocker or LUKS2 is configured for silent TPM-only unlock (without a pre-boot PIN), the TPM automatically releases the Volume Master Key over the motherboard's discrete SPI or LPC bus as soon as the boot chain passes PCR checks. On laptops with discrete TPM chips, an attacker can tap the SPI pins with a logic analyzer and read the cleartext key in seconds unless `tpm2-pin=yes` / BitLocker Pre-Boot PIN is required.

Why is PCR 7 + PCR 11 preferred over PCR 0 + PCR 4 + PCR 8/9 on modern Linux?+

Binding directly to PCR 4 (raw bootloader code hash) means every routine kernel or systemd update changes the PCR digest and breaks TPM unlock. By binding to PCR 7 (Secure Boot authority state) and using signed PCR 11 policies (`systemd-measure`), any kernel signed by your enrolled private key unlocks seamlessly while unsigned tampering is blocked.

Why does LUKS2 use Argon2id instead of PBKDF2?+

Legacy LUKS1 used PBKDF2-HMAC-SHA256, which only consumes a few kilobytes of memory and can be parallelized across thousands of GPU shaders. LUKS2 defaults to Argon2id—a memory-hard key derivation function that requires up to 1–4 GB of dedicated RAM per password guess, neutralizing GPU brute-force acceleration.
