CyberPipe v5.3: Enhanced PowerShell Compatibility and Reliability

DFIR, Forensics, PowerShell, RAM, Triage, USB, Windows

I’m pleased to announce the release of CyberPipe v5.3, bringing critical compatibility improvements for Windows PowerShell 5.1 and enhanced reliability across all PowerShell environments.

The Problem

After releasing v5.2 with the new unified banner design, several users reported an interesting issue: CyberPipe would execute perfectly in PowerShell Core, but in Windows PowerShell 5.1, the script would complete the Magnet Response collection successfully—then immediately fail with an exit code error and stop before running EDD and BitLocker key recovery.

The collected artifacts were there. The output looked successful. But the script refused to continue.

The Root Cause

This turned out to be a known quirk in Windows PowerShell 5.1: the $process.ExitCode property isn’t always reliably populated after calling WaitForExit() on a process object. Even when Magnet Response completed successfully with exit code 0, PowerShell 5.1 would sometimes report a non-zero value, causing CyberPipe to think the collection had failed.

The Solution

Version 5.3 introduces dual validation logic that checks both the exit code and verifies that files were actually collected. If Magnet Response reports a non-zero exit code but artifacts were successfully collected, CyberPipe recognizes this as a PS 5.1 reporting issue and continues the workflow with a warning message.

The script now validates success based on what actually matters: did we collect the evidence?

Bonus: Adaptive Banners

While fixing the PS 5.1 compatibility, I also enhanced the banner display:

  • PowerShell Core: Displays the full Unicode box-drawing banner with visual flair
  • Windows PowerShell 5.1: Shows a clean ASCII banner optimized for automation, EDR deployment, and environments where Unicode rendering may be inconsistent

The script automatically detects which PowerShell edition is running and adjusts accordingly.

Testing & Validation

CyberPipe v5.3 has been tested and verified on:

  • ✅ Windows PowerShell 5.1
  • ✅ PowerShell Core 7.x
  • ✅ All collection profiles (Volatile, RAMOnly, RAMPage, RAMSystem, QuickTriage, Full)

The script now executes flawlessly in both environments with no workflow interruptions.

Compatibility Notes

This is a drop-in replacement for v5.2 with no breaking changes:

  • All command-line parameters work identically
  • Existing automation scripts require no modifications
  • All collection profiles function as before

Why This Matters

For incident response work, reliability is non-negotiable. When you’re collecting evidence from a potentially compromised system, you need tools that work consistently across different Windows environments—corporate workstations running PS 5.1, modern systems with PS Core, virtual machines, and physical hardware.

CyberPipe v5.3 ensures that whether you’re running an interactive collection or deploying via EDR automation, the script executes reliably from start to finish.

Streamline Digital Evidence Collection with CyberPipe 5.2

DFIR, Forensic Imaging, PowerShell, USB, Forensics, Triage

I first wrote CyberPipe when I was on the front lines of incident response, driven by the need for more robust and efficient triage collections, whether online or off.  Over the years, CyberPipe continues to adapt and improve, addressing the ever-changing challenges faced by incident response practitioners. 

CyberPipe (formerly CSIRT-Collect) is a PowerShell script that is designed to streamline the collection of digital evidence using Magnet Response in enterprise environments, ensuring that responders can gather critical data efficiently and effectively.  Other features include detection of encrypted drives, BitLocker key recovery, and memory image collection.

The most recent update includes enhancements in three areas: Collection, Capabilities, and Reliability.

🔍 What’s New in 5.2

Intelligent Collection

  • The script now includes dual disk space validation, checking both the target drive and the system drive with profile-aware thresholds to prevent sudden failures due to insufficient space. 
  • A pre-collection volatile snapshot captures uptime, users, connections, and processes to preserve transient state before heavy operations begin.
  • Reports virtual environment detection (VMware, Hyper-V, VirtualBox, etc.) to help analysts understand collection limitations.
  • Real-time progress indicators provide accurate size tracking during the collection, offering responders visibility into the remaining data capture.

Enhanced Capabilities

  • The new QuickTriage profile allows for rapid collection of volatile and system artifacts when time is ticking.
  • BitLocker recovery now includes all volumes, not just the C: drive.
  • A single-file report (CyberPipe-Report.txt) consolidates metadata and a summary of collected artifacts in a human-readable format.
  • All collected artifacts and logs are hashed using SHA-256 to enhance integrity and chain of custody.
  • Output compression is available via the -Compress flag, aiding in storage and transfer.
  • Network collection is simplified with the -Net parameter, eliminating the need for manual network path or configuration edits.

Improved Reliability

  • Profile-aware space checks alert when free space is insufficient for a chosen profile, preventing silent failures.
  • The script now validates exit codes from MAGNET Response to detect failures more effectively.
  • Artifact verification after collection ensures that all expected items were gathered.
  • Error handling and messaging have been refined to provide clearer feedback to the operator.

What I’m hoping this delivers

CyberPipe 5.2 aims to address some challenges observed in real-world triage and live-response operations:

  • Resilience in constrained environments — dual drive checks and profile awareness help prevent mid-collection failures.
  • Better transparency and oversight — real-time progress display and post-collection verification enhance confidence.
  • Faster response options — the QuickTriage profile is suitable when speed is paramount.
  • Stronger forensic hygiene — SHA-256 hashing, improved error detection, and full-volume BitLocker key recovery contribute to defensibility.
  • Easier network deployments — built-in ‘-Net‘ support facilitates smoother remote collection.

As always, CyberPipe is freely available at https://github.com/dwmetz/CyberPipe. Forks and Contributions welcome and appreciated. 

Is there a feature you’d like to see? I think next I might work on support for copying output to AWS/Azure. Thoughts?

Toby-Find: Simplifying Command-Line Forensics Tools

DFIR, Forensics, Malware, Memory Analysis, Raspberry Pi, Triage

In digital forensics, we often take a toolbox approach — success hinges on having the right tool for the job. Some tools offer broad functionality, while others are deeply specialized. Distributions like KALI and REMnux do a fantastic job bundling a wide range of forensic and security tools, but keeping track of what’s actually installed can be a challenge.

If you’re using a graphical interface, browsing through available packages is fairly intuitive. But when you’re living in the terminal — as many analysts do — that discoverability disappears. There’s no built-in index of command-line tools or how to invoke them.

The first version of Toby-Find was born out of necessity. I teach a Network Forensics course at the university, using a custom VM loaded with tools like Zeek, Tshark, Suricata, and more. I wanted students to have an easy, searchable way to see what CLI tools were available and how to run them — without needing to memorize commands or dig through man pages.

Later, when I built Toby (a forensic-focused Raspberry Pi rig running a customized KALI install), I updated Toby-Find to include the complete CLI toolset geared toward forensics and malware analysis from the KALI ecosystem.

And because I can’t leave well enough alone, I decided to build a REMnux-compatible version too.

⸻

Once installed, you can launch Toby-Find (via tf, toby-find, or tf-help) from any terminal and instantly search for tools, descriptions, examples, and more.

Whether you’re working from a custom VM, a rugged Pi, or a hardened REMnux box, Toby-Find gives you a fast, terminal-friendly way to surface the tools at your disposal — without breaking focus. It’s lightweight, portable, and easy to extend for your own lab or classroom.

You can grab the full installer from GitHub, and contributions are always welcome. If you find it helpful — or build on it — I’d love to hear about it.

Sharper Strings and Smarter Signals: MalChela 3.0.1

DFIR, Forensics, Malware, Rust, Triage

It’s a strange but satisfying feeling to hit version 3.0, then realize soon after you’re already back in the weeds fixing, refining, and optimizing. That’s what this 3.0.1 release is all about — a tight round of updates aimed at boosting clarity and cutting noise, especially when running mStrings or working within the FileMiner panel. Additionally, a number of optimizations came about in getting MalChela to run smoothly on Toby, and to minimize any unnecessary re-building of the binaries. This post walks through what’s new and improved.

🧠 Smarter Detections in mStrings

The mstrings tool — one of the most feature-rich in the toolkit — got a round of refinements:

  • Generic Executable detection removed: This was too noisy and matched a lot of clean files. It’s been replaced by more focused patterns.
  • Suspicious DLLs now detected more precisely: Legit Windows DLLs like ole32.dll and gdiplus.dll are now excluded unless they’re paired with indicators like GetProcAddress, LoadLibrary, or manual syscall patterns.
  • Rule cleanup and expansion: Several detections were removed, refined, or added (like packer stubs and dropper markers) to better target actual malicious behavior.
  • Tighter MITRE mapping: Each detection is now carefully aligned to a corresponding MITRE ATT&CK technique, often down to the sub-technique level.

If you’ve ever run mstrings and felt unsure which hits mattered most — or got buried in generic noise — this update should feel much cleaner.

Reminder: You can easily update the detection criteria by modifying detections.yaml.

🔍 Built-In MITRE Lookup (GUI)

If a detection shows a MITRE ID like T1082, you can now look it up directly inside the GUI. The new MITRE Lookup Bar sits at the top of the config panel (only when running mstrings). Paste a technique ID, hit Lookup, and it’ll open the official MITRE ATT&CK page in your browser.

🗂️ FileMiner Improvements

The FileMiner GUI panel saw some polish too:

  • “Select All” functionality: You can now batch-run tools across multiple matching files in a case — a huge time-saver during triage.

🧰 Build and Setup Updates

Two quick notes for folks cloning the repo for the first time:

  • The release.sh script now builds all binaries in release mode — one command to build everything cleanly.
  • Docs and README were updated to recommend building in –release mode from the start, especially for smoother GUI usage.

🧪 Platform Testing

Confirmed functional on:

  • macOS (Silicon)
  • Ubuntu (Desktop and minimal)
  • REMnux (custom REMnux tools.yaml)
  • Raspberry Pi (Zero 2W and 4B)
  • Windows via WSL (CLI)

Still some quirks with native Windows support due to YARA compatibility and pathing, but if you’re a Windows power user and want to pitch in, I’d love your help.

💭 Final Thoughts

MalChela isn’t trying to replace your favorite tools — it’s trying to bundle them in ways that save time, reveal context, and give you clarity during analysis. The 3.0.1 release doesn’t bring sweeping new features, but it does make the experience tighter, more predictable, and more useful where it counts.

As always, thanks to those who’ve tested it, given feedback, or just watched quietly from the shadows. 🕵️‍♂️ If you want to contribute — whether it’s rules, regex, docs, or bugs — you’ll find me at dwmetz/MalChela.

Happy hunting.
