What if I told you there is an immensely popular operating system that you likely used it at least once, but did not realise what it was?

In fact, it is so popular and important there is an IEEE standard based on it.

It is uncanny how immensely popular AND immensely obscure this system is.

It is scary that until today I have never even heard of its reference desktop implementation.

The system is called "TRON".

p.s. thanks @fkinoshita for the pointer!

pretty amazing and feels magical to run three snippets each on different operating systems, with zero setup needed (batteries included) #macdev #swiftlang #python #linux #notepadexe

1. Python on Linux
2. Swift on Linux
3. Swifton macOS

Finally I can ditch my tired old Sparc station, and switch to #Windows like everyone else!

Introducing SSH2WIN a port of SSH2DOS to #16bit Windows. No win32s here!

This was both harder and easier than I thought it would be.

Official release coming soon, once I clean up some details.

I found a Linux kernel security bug (in AF_UNIX) and decided to write a kernel exploit for it that can go straight from "attacker can run arbitrary native code in a seccomp-sandboxed Chrome renderer" to kernel compromise:

This post includes fun things like:

• a nice semi-arbitrary read primitive combined with an annoying write primitive
• slowing down usercopy without FUSE or userfaultfd
• CONFIG_RANDOMIZE_KSTACK_OFFSET as an exploitation aid
• a rarely-used kernel feature that Chrome doesn't need but is reachable in the Chrome sandbox
• sched_getcpu() usable inside Chrome renderers despite getcpu being blocked by seccomp (thanks to vDSO)
