Today, we announce the release of **Falco Talon 0.3.0** 🦅!

Three updates in a row, after [Falco](https://falco.org/blog/falco-0-40-0/) and [Falcosidekick](https://falco.org/blog/falcosidekick-2-31-0/), it's time for [Falco Talon](htts://docs.falco-talon.org) to know a new version.

## What's new?

The key feature this release brings is the new actionner `kubernetes:sysdig`. For those who are not familiar with [sysdig](https://github.com/draios/sysdig), it's a CLI tool that allows to capture and record the syscalls, like `tcpdump` does for the network packets. Old brother of Falco, they share the same libs and filters.

With this new integration, when a suspicious event occurs in a pod, Talon triggers a capture and then exports the created artifact to AWS S3 or Minio. You can configure the `duration` and the `amount of bytes` captured for each syscall. Check out the [docs](https://docs.falco-talon.org/docs/actionners/list/#kubernetessysdig) to discover more settings.

See this example rule:

```yaml
- action: Capture the syscalls
actionner: kubernetes:sysdig
parameters:
buffer_size: 2048
duration: 20
output:
target: minio:s3
parameters:
bucket: falco-talon
prefix: /sysdig/
```
After the action has been completed, you'll find the capture in Minio:

And you can run the CLI tool `sysdig` to explore it:

```shell
❯ sysdig -r 2025-01-23T13-26-41Z_default_cncf-597d69dbd4-h9fcb_sysdig.scap.gz evt.type=execve and evt.dir=">"

```
