  • TripleCross

    A Linux eBPF rootkit with a backdoor, C2, library injection, execution hijacking, persistence and stealth capabilities.

    Project mention: eBPF – Running sandboxed programs in a privileged context such as OS kernel | news.ycombinator.com | 2022-11-06

    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.

  • tilck

    Project mention: A future without containers? ( thoughts ) | reddit.com/r/freebsd | 2022-11-10

    Wow, just now seeing this topic. I work for a cloud company hosted in AWS. We started out, Netflix/Spotify style microservices. We were all on ec2 images generate by packer (and later with AWS Image Factory). When Docker hit, we kicked the tires but never did anything with it beyond using it for running unit tests, and later, infrastructure tests. 5 years ago, during a hackathon, our little group began experimenting with Unikernels, or library operating systems. Interestingly enough, these Unikernels were all stripped down BSD kernels. OSv is FreeBSD based, and Rumprun is NetBSD based. Services running in EC2 on Unikernels would spin up and start sending and receiving traffic before the AWS EC2 healthchecks completed. They are blazing fast! Only problem in 2017, was the tooling. It would have taken too much effort to use Unikernals with our infrastructure. As soon as they start making Unikernels that can run Java bytecode like native code, the fate of containerization will be sealed, IMO. We could get basic JVM webservers running on OSv, but not Cassandra, not Kafka, not yet. OSv now runs on Firecracker, but I have not tried it out, yet. Some links if you are interested: OSv: https://osv.io Rumprun: https://github.com/rumpkernel/rumprun We used this tooling during the Hackathon, but doesn't look like it has been touched in 3 years: https://github.com/solo-io/unik Unikraft Unikernel Dev kit: https://unikraft.org/ And don't forget Firecracker running in Kubernetes https://www.weave.works/oss/firekube/ And of course, being a FreeBSD subreddit, let's not forget FreeBSD on Firecracker https://www.daemonology.net/blog/2022-10-18-FreeBSD-Firecracker.html

  • pwru

    Packet, where are you? -- eBPF-based Linux kernel networking debugger

    Project mention: A list of new(ish) command line tools – Julia Evans | news.ycombinator.com | 2022-04-12

    [pwru](https://github.com/cilium/pwru) is a fun new tool from the Cilium folks for tracing network packets in the kernel. Like tcpdump but it shows you the full path including kernel syscalls. Lets you debug much deeper than "when the packet gets to this port it gets dropped".

  • h-encore
