Technical Review: A Deep Analysis of the Dirty Pipe Vulnerability

Technical Review: A Deep Analysis of the Dirty Pipe Vulnerability

Dirty Pipe (CVE-2022-0847) proved that there is a new way to exploit Linux syscalls to write to files with a read-only privileges. The fact that someone can write to a file regardless of its permissions is a big security threat. An application of this vulnerability would be to write on the host from an unprivileged …

Using CO:RE to Achieve Portable Tracee eBPF Code

Using CO:RE to Achieve Portable Tracee eBPF Code

One of the biggest challenges of eBPF development is distribution of your eBPF project. With so many different versions of the Linux kernel out in the wild, it seems like an impossible task to compile your eBPF program against all of them to ensure compatibility. However, by using CO:RE, a feature of libbpf, this gets …

Detecting Malicious Activity in CI/CD Pipeline with Tracee

Detecting Malicious Activity in CI/CD Pipeline with Tracee

With the growing popularity of CI platforms to build software, bad actors are increasingly looking to exploit these environments to target organizations. In our post about the recent Codecov breach, we explored how an attacker was able to get access to credentials from within the CI/CD pipeline. To prevent this from …

How to Build eBPF Programs with libbpfgo

How to Build eBPF Programs with libbpfgo

In recent years, I have been I using a project called BCC to compile, load, and interact with my bpf programs. I have recently learned about a better way to build ebpf projects called libbpf. There are a few good resources to use when developing libbpf based programs but getting started can still be quite …

What is vmlinux.h and Why is It Important for Your eBPF Programs?

What is vmlinux.h and Why is It Important for Your eBPF Programs?

eBPF is a powerful and exciting technology that allows developers to add custom code to strategic points in the Linux kernel and interact with it by writing simple C or Go programs. The eBPF programs you write and run can inspect data in the memory of processes they attach to. In order to do so, however, the eBPF …
