Self-isolated hackers, assemble!

3 new tutorials and a new VM for you to play around with:

Lab VM 2.0: https://azeria-labs.com/lab-vm-2-0/ 

Emulating Router Firmware: https://azeria-labs.com/emulating-arm-firmware/

Stack Overflows: https://azeria-labs.com/stack-overflow-arm32/

XN Exploit Mitigation and ROP: https://azeria-labs.com/return-oriented-programming-arm32/

The new Lab VM contains:

- QEMU emulated Armv7 environment ready to start

- Two different Tenda router firmware versions (AC6 and AC15)

- All scripts necessary to start the firmware emulation

- Two small Arm exploitation challenges to learn the basics of bypassing XN

The Emulation tutorial walks you through the process of emulating Arm Router firmware. If you want to skip that and dive straight in, the Lab VM already contains all scripts and firmware ready to start up.

The Stack Overflow tutorial covers what happens under the hood when you see a segmentation fault and how to take control over the program counter for further exploitation.

The XN and ROP tutorial teaches you how exploitation changes with the XN mitigation & what ROP chains are.

I wrote this up in a day and now I have a migraine lol.

Time to rest. To all you sitting in self-isolation, I hope you enjoy the distraction and have fun playing around with the VM. :)
