CyberPipe v5.3: Enhanced PowerShell Compatibility and Reliability

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.
