In the coming weeks, I will publish new articles covering exploration in areas such as Windows, Chrome, iOS/macOS, and hypervisors.

I sincerely hope these articles help other professionals define their own steps in this area.

Have a great day and enjoy reading.

👶🎩 Ah, the classic tale of a newbie coder's first foray into Linux kernel hacking. It's a gripping saga of hair-pulling sign-extension bugs and hypervisor mysteries that only 3 people on Earth truly understand. Dive in, if you dare, to this epic chronicle of reinventing the wheel—because who needs existing #hypervisors anyway? 🙄🔧

Finally organized my thoughts into a blog post around the state of hypervisors in my home lab, with some new hardware. I also called out a few nice features of XCP-NG and Proxmox that I discovered while I was evaluating both of them.

Supposed "hard" limits can as well be enforced with #containerization. It is just less common and not necessarily desired.

And no, those limits are not hard, and no, #hypervisors do not guarantee isolation either - see e.g. all the recently revealed #VMWare bugs with integer overflows and underflows, array out-of-bound accesses etc..

https://www.bleepingcomputer.com/news/security/vmware-fixes-four-esxi-zero-day-bugs-exploited-at-pwn2own-berlin/

⚠️ Just a reminder, folks:

The "container" movement on Linux emerged as a convenient way to manage different, possibly conflicting settings & dependencies for different apps on a machine. "Security" by sandboxing got tacked on later, and the quality of that isolation remains LOW regardless of all the trendy project names and acronyms that have filled that space.

Data centers' standard for high security consists of virtual machines (type 1 hypervisors) or separate dedicated hardware. Ain't no way, no how is a successful datacenter going to ask a giant, complex, contorted Linux or BSD (or hybrid Windows or Mac) kernel for sandboxing services to contain threats.

If you are using containers to enhance security – on any general-purpose machine – make sure they are running as VMs, or as sandboxes on a microkernel (not monolithic) architecture.

🤡 Apparently, we're supposed to be impressed that these folks can build #hypervisors, because everybody else is just a clueless poser stacking virtual Legos. Meanwhile, they're busy patting themselves on the back for not mistaking their keyboard for a toaster. 🧠💡

When a developer learns kubernetes microservices, works on a windows laptop protected by cyberark and behind bluecoat and must become a devsecops expert.

#GPU-accelerated #VM on #Proxmox, #XCPng? Here's what you need to know
Two of the biggest beneficiaries of #Broadcom's price hikes, at least on the free and #opensource side of things, have been the Proxmox VE and XCP-ng #hypervisors.
In this #tutorial, we'll be looking at what it takes to pass a GPU through to VMs running on either platform, and go over some of the more common pitfalls you may run into.

Обзор гипервизора Harvester 1.3.0

В процессе поиска подходящей платформы для того, чтобы инсталлировать Kubernetes у себя дома, я эксперементировал с разными вариантами. В этой статье - делюсь опытом работы с этой системой. Что такое Harvester? Официально - A Cloud Native Open Source Hyper-converged Infrastructure. Если попробовать сказать простыми словами - то эта операционная система, которая предназначена для запуска и управления Kubernetes, виртуальных машин и система хранения данных (СХД). Вот такая иллюстрация на сайте Harvester:

It must be Christmas because the #blog posts from my team at #linaro keep coming. In this one @ablu discusses how we have leveraged #rust to build portable #virtio backends that can be built to support multiple #hypervisors: https://www.linaro.org/blog/rust-device-backends-for-every-hypervisor/

While collecting the evidence in 2023 we (Marco Lux & Pedro Umbelino) recognized the ESXi attack by a random #ransomware group. We decided it is time to publish our results which cumulated in CVE-2023-29552 #vuln #forensics ( via John Kristoff )

Interestingly, #internet search engines like @shodan, still missing SLP in their collection, which is a pity. #ddos #systems #devices #products #services #tools #routers #management #cyber #printers #daemons #hypervisors #networks #threats #informatique

Listening to aNONradio by having qemu redirect OSS output to /dev/audio. Performance is good with 2 dedicated cores and 4G of RAM.
