DirtyCred
falco
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.
DirtyCred
- DirtyCred: DirtyCred is a kernel exploitation concept that swaps unprivileged kernel credentials with privileged ones to escalate privilege. Instead of overwriting any critical data fields on kernel heap, DirtyCred abuses the heap memory reuse mechanism to get privileged.
- DirtyCred: Linux Kernel Privilege Escalation
- GitHub - Markakd/DirtyCred
- DirtyCred (vulnerability for Linux found at BlackHat conference) - what is the deal with this? Media is making headlines about it but nothing here?

Blackhat 2022 recap – Trends and highlights
The new exploitation method presented by Zhenpeng Lin is called DirtyCred and is based on swapping Linux Kernel credentials. It’s simple, effective and generic. This allows it to perform container escape and still be an actual threat.

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.

K8s secret management
Use some kind of SIEM or Falco to alert you to threats (you can't stop them, but a human can always intervene)

How to Deploy and Scale Strapi on a Kubernetes Cluster 2/2
Falco, is a security project that can help you detect threats from within your cluster.
- Opensource IDS for Kubernetes??

Go based eBPF projects
https://falco.org/ is a security-focused monitoring and alerting with an eBPF option
- Is there a utility that can send shell command to all pods?

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.
