What We Are Particularly Excited About
In this release we are particularly excited about these new Slips features:
1.1.21 (Jun 1st, 2026)
* Improve Slips security by updating dependencies, reducing shipped build tools, sanitizing inputs, and improving permissions.
* Secure the Slips web interface by binding it to localhost and adding CSRF protection.
* Drop support for `webinterface.sh`. Now the web interface starts only with `-w`.
* Kill the redis server opened by Slips once the analysis is done, and save a Redis database snapshot for later analysis in the output directory.
* Support analyzing a redis dump.Rdb using the web interface.
* Add TOR exit nodes detection.
* Fix issue with TI feeds not updating periodically.
* Add detection for telnet, rlogin, and rsh logins using zeek scripts.
* Stop Slips on core module failures.
* Scale profiler workers down when throughput drops to reduce resource usage.
* Fix issue starting P2P in access point mode (-ap).
* Auto-rebuild Go binaries when needed after Slips is done auto-updating.
* Fix daemon shutdown with `-S`.
