Breachwright 2.4.1

Breachwright 2.4.1

Breachwright 2.4.1 is a Windows packaging hotfix. Advent Cybersecurity created
Breachwright and releases the complete application as open-source software for
the security community. Windows and Linux packages continue to contain the
same feature set, with no accounts, activation, paid editions, seat limits, or
feature gates.

Windows startup fix

• Added .NET runtime configuration beside both Windows executables so the
  bundled Python.NET and WebView2 components load when Windows propagates
  internet-zone metadata from the downloaded ZIP to DLLs.
• Fixed the first-launch failure that reported an inability to resolve
  Python.Runtime.Loader.Initialize from Python.Runtime.dll.
• The fix preserves Windows download-origin metadata. It does not silently
  remove the Mark of the Web from bundled files.

Stronger release validation

• The packaged desktop test now requires the application window to be shown,
  not only the local backend health endpoint to respond.
• The Windows candidate workflow applies internet-zone metadata to the
  packaged Python.NET DLL and verifies that the desktop still opens.
• Windows and Linux native package, installation, upgrade, and archive gates
  remain required before publication.

Downloads

• breachwright-2.4.1-windows-x64.zip
• breachwright-2.4.1-linux-x64.tar.gz
• SHA256SUMS.txt

Verify the published SHA-256 checksum before installation. The Windows
executables are not currently Authenticode-signed, so Windows may show an
unknown-publisher or Microsoft Defender SmartScreen warning. Download only
from the official Advent Cybersecurity GitHub release and do not run files if
their checksums differ from SHA256SUMS.txt.

Back up the workspace from Settings > Data Safety before upgrading. This
hotfix adds no database migration and does not change saved assessment data or
provider configuration. AI remains optional, and using a commercial provider
can incur charges from that provider.
