Getting Started Reverse Engineering Bare Metal Kernel Images - (Part 1/Setup) | This is a series, more will be released soon.

Arent all kernels bare metal kernels? Iv not seen one that is specifically designed to run in a VM. I dont doubt that one may exist, but ive never seen one.

Hey man, good write up :)

Can I ask what do you refer to as a "kernel"? In my experience, kernel is generally only used to refer to a component of an OS.

I'd generally describe a bare metal firmware as having no kernel. And the built application is just a binary, or a firmware image.

List of Popular Applications that use the `--no-sandbox` flag when running Chromium and Chrome based Applications and may expose users to RCE vulnerabilities.

This is literally just a list of Electron apps...

I'm not sure what "Untrusted desktop application without source code" has to do with sandboxing... if they wanted to give you malicious code, they don't need to use JS to do it. This feels like the author fundamentally doesn't understand the purpose of the sandbox and/or the security issues at hand.

Similarly with extensions, it seems pretty dumb to assume that a malicious extension in many of these applications wouldn't be able to cause damage regardless, especially considering that some of the extensions (e.g. for Teams, VSCode) are designed for performing file-system operations already.

It's also odd to me that this list doesn't separate what I would consider to be the biggest distinction for a discussion of sandboxing, which is whether or not the app renders web content from untrusted sources (e.g. chat rooms). I believe that would exclude VSCode, but would include Twitch, Slack, Signal, FBM, Teams, Discord, and Keybase. However, I don't think any of these intentionally accept arbitrary JS, so exploits still seem unlikely without some kind of additional XSS exploit.

What's the concern with Slack if it's sandboxed? That it's not open source?

MITRE ATT&CK Evaluation
Good morning all,

Might be useful information for red teamers with knowing product and what may get past with little to no information passed to blueteams.

Easy Malware to Reverse Engineer
Hey I have recently been analyzing some sample malware and everything I can find is for people far more advanced than me. Does anyone know were I can find some simple malware examples? I am using IDAPro and WinDbg

There is https://github.com/ytisf/theZoo

It has the reversed source code too

If you havenโ€™t already, working throughout the exercises and chapters in Practical Malware Analysis is a good starting point.
