This is an experimental release intended to test new features for Stratoshark 1.0.

What is Stratoshark? Stratoshark is a system call and log analyzer. It combines the analysis and filtering features of Wireshark with the capture and data enrichment features of Falco. It can be used for troubleshooting, analysis, development and education. Stratoshark is hosted by the Wireshark Foundation, a nonprofit which promotes protocol and system analysis education. Stratoshark and the foundation depend on your contributions in order to do their work. If you or your organization would like to contribute or become a sponsor, please visit wiresharkfoundation.org.

What’s New The following changes have been made since version 0.10.0:

• The Stratoshark Windows installer now includes a DLL that was required by the cloudtrail and gcpaudit plugins.
• The following issues have been fixed:
  • Wireshark appears in German where Systemlanguage is Dutch. Issue 20347.
  • If you double-click an interface in the welcome screen interface list, and have typed nothing in the capture filter box, the system reports an invalid capture filter. Issue 21303.
  • Qt: Appearance mode is stored per-profile while theme name is global — theme flips on profile switch. Issue 21311.
  • Qt: ‘Recent filters’ arrow button gives no hover/pressed feedback. Issue 21322.
  • Qt: Hidden interfaces (Welcome page right-click) not persisted across profile switch or restart. Issue 21325.
  • Qt: Preferences dialog left category tree cannot be resized (labels truncated, only horizontal scrollbar) Issue 21327.
  • Stratoshark: no-libpcap compilation broken (actionCaptureRestart) — fix from 554baf6294 never applied. Issue 21328.
  • Qt: Make theme preview resemble a real Wireshark window (mini packet-list mockup) Issue 21329.
  • stratoshark -D lists a bunch of network capture devices. Issue 21332. The following changes have been made since version 0.9.3:
• Stratoshark can now read Process Monitor (Procmon) files.
• Welcome Page Redesign: The welcome page has been redesigned to be more informative and easier to navigate. It now highlights the learning sections better and includes a new sidebar with tips and tricks for using Wireshark effectively. The welcome page is now also more accessible, with improved keyboard navigation and screen reader support.
• Lua Debugger: A built-in Lua script debugger has been added. It supports breakpoints, single-stepping, variable inspection, expression evaluation, and stack traces.
• Themes: Stratoshark now uses the same theme system as Wireshark, driving the colors used throughout the GUI from a single theme instead of many individual color preferences. The renamed Appearance › Theme and Font preferences page lets you pick a theme, switch between Light, Dark, and System appearance, set the packet pane font, and preview the result. A built-in default theme ships with Stratoshark, and additional themes can be installed as JSONC (JSON with Comments) files. The previous per-color settings are now provided by the active theme. Personal themes can be dropped as single .jsonc files into $HOME/.local/lib/stratoshark/themes (Unix) or %APPDATA%\Stratoshark\themes (Windows); the filename becomes the theme’s name in the dropdown. On first launch after the upgrade, Stratoshark checks the Default profile’s preferences for customized values of the removed per-color settings. If any are found, a personal theme named Personal (Migrated) is created automatically, the legacy keys are removed, and the theme is activated so the original visual customizations are preserved.
• Zooming (View › Zoom In / View › Zoom Out) now scales the whole window, including the capture and display filter fields and other window elements.
• The keyboard shortcuts dialog has been moved to View → Internals → Keyboard Shortcuts and now has a button to print the list of keyboard shortcuts to an HTML file.
• The application icon has been updated to support Liquid Glass on macOS Tahoe.
• Stratoshark and strato can now read plain Kubernetes Audit logs and Google Cloud Audit logs, and CloudTrail logs.
• The CloudTrail and Google Cloud Audit log plugins have been translated to Rust on macOS and Windows. Issue 20869 The following changes have been made since version 0.9.2:
• The Windows installers now ship with Qt 6.8.3. They previously shipped with Qt 6.8.1.
• Stratoshark now ships with “strato”, a command line tool similar to tshark.
• The Windows and macOS packages now ship with the gcpaudit and k8saudit plugins.
• The Falco Events dissector now adds IP geolocation fields alongside IPv4 and IPv6 address fields. The following changes have been made since version 0.9.1:
• A new “Plots” dialog has been added, which provides scatter plots in contrast to the “I/O Graphs” dialog, which provides histograms. The Plots dialog window supports multiple plots, markers, and automatic scrolling.
• The Falco Bridge dissector has been renamed to Falco Events. Filter fields now have a “falcoevents” protocol prefix, but a “falcobridge” protocol alias has been added for backward compatibility. Issue 20397
• Stratoshark can now show field offsets for supported plugins.
• Cloudtrail log messages can now be viewed as formatted JSON data.
• The system call dissector now has a “falcoevents.fd.stream” field, which provides a unique number for each file descriptor. The “Follow File Descriptor Stream” feature now uses this field to track streams. Issue 20538
• We now ship universal macOS installers instead of separate packages for Arm64 and Intel. Issue 17294 The following changes have been made since version 0.9.0:
• The application icons have been updated.

Bug Fixes The following bugs have been fixed since version 0.9.3:

• Interfaces hidden from the welcome page are now remembered across profile switches and restarts. Issue 21325 The following bugs have been fixed since version 0.9.2:
• .scap file extension wrongly associated with Wireshark. Issue 20583.
• sshdig should have a snaplen option. Issue 20586. The following bugs have been fixed since version 0.9.1:
• Stratoshark help message has Wiresharkisms in it. Issue 20229.
• Stratoshark and editcap could write incorrect block types. Merge request 19238.
• Stratoshark says I can’t capture on local interfaces. Issue 20494.
• Stratoshark: Crash While Sorting on evt.buflen column. Issue 20571. The following bugs have been fixed since version 0.9.0:
• Falco Bridge: Empty frame.protocols field. Issue 20248.
• Sysdig event and Falco bridge dissection mismatch due to unsupported pcapng block types. Issue 20358.

New and Updated Features Stratoshark can capture system calls locally on Linux and a variety of log sources on Windows, macOS, and Linux. The following features are either new or have been significantly updated since version 0.9.0:

• The welcome screen’s capture-source activity sparklines now keep their history for the whole session. Previously the sparklines, and the activity-first ordering of the source list, were reset whenever you started or stopped a capture or returned to the welcome screen, so the list re-shuffled each time. Now the history persists, the ordering stays stable, and a break in a sparkline marks the interval during which a capture was running (statistics are not sampled while capturing). When a source is dropping packets, the drops are shown as a separate line. Issue 21318

Removed Features and Support

• Dumpcap’s TCP@host:port interface has been removed.
• Building with Qt 5 is no longer supported.
