Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Writing to file in kprobe
Not going to find too many guides for BPF development. Best way to learn is by looking at existing code samples, like this repo

eBPF – Running sandboxed programs in a privileged context such as OS kernel
This is a good write-up and I like the diagrams. What appears to still be missing in an "off switch". AFAIK there are still no kernel boot time commands to disable eBPF entirely. I have to recompile the kernel to disable it.
eBPF has the potential for file-less malware to run hidden from detection and I foresee the ability to tickle ring -3 (and -4?) CPU within CPU functions while bypassing local firewalls.
Here is some example code of what people already know how to do today and this list will grow as people discover more capabilities. [1][2][3][4][5] These do require some privileges to insert but will remain running and hidden until reboot.

Boopkit: eBPF backdoor (TCP) for spawning reverse shells
For anyone interested, there are a few more projects with similar capabilities to look at:
- Bad-bpf: https://github.com/pathtofile/bad-bpf
- Offensive BPF: https://embracethered.com/blog/posts/2021/offensive-bpf/

Kubernetes security projects for entry grad roles in DevSecOps/Cloud security
From one noob to another - I had a lot of fun setting up Falco (https://falco.org) and creating custom policies & alerts.

An Overview of Kubernetes Security Projects at KubeCon Europe 2023
Falco is a well-known open source security solution originally created by Sysdig. It’s a CNCF incubating project and one of the few (as far as I can tell) options on this list that uses eBPF to scan for vulnerabilities.

Use some kind of SIEM or Falco to alert you to threats (you can't stop them, but a human can always intervene)

My GoLab 2022 experience
On the cgo side I want to highlight two talks: one from Loris Cro about dealing with cross-complition difficulties, that the usage of cgo brings, using the Zig language and the other from Jason Dellaluce and Leonardo Grasso about how to extend Falco, a Kubernetes threat detection engine, which is written in C++, with plugins written in Go, explaining the challenges of integrating cgo in both C and Go.
