I'm also trying to understand the implications of this work.

Does it imply that some for some functions F(x) = y, you can compute x given the value of y without computing the inverse of F ?

If so, what constraints does F need to meet for this ?

Most countries don't have for profit prisons or detention centers.

I believe it ships with its own kernel

> The TinyKVM guest has a tiny kernel which cannot be modified.

I wonder if someone has already made a Reverse Engineering CTF challenge for this concept.

There actually was one with subleq: https://www.google.com/amp/s/blog.attify.com/flare-4-ctf-wri...

I would also be very curious to see if it's possible to make a decompiler for this type of obfuscated program.

Typically these obfuscators are applied in an automated fashion so yes.

DEFCON Quals challenge incoming.

Please no we’ve already suffered enough :(

I read it as reverse engineering WTF challenge... cool stuff though, seriously.

The jargon of 0-day and n-days are pretty common in the vulnerability detection community. The rest of your rant is pretty difficult for me to understand though.

This only affects anyone that wants to spin up VirtualBox VM's on Linux hosts.

I'm not an expert in this field, but my best TL;DR is that VirtualBox and other VMM's (virtual machine monitor) used to ship with their own hypervisors (the thing that let's you run virtual machines). However, now Linux has its own hypervisor/framework (KVM) and now VirtualBox can use KVM to do all the functionalities their own hypervisor used to do.

Someone please correct me if I'm wrong

Thanks! Appreciate it.

This is article is way too old to be relevant right now. Back in 2016, Instagram and snapchat were just developing. And honestly I'd like to see a comparison between this study and a more recent one to see if the results actually match.
