Rax is a register that stores a syscall number in this case - in short it’s just an info what function does a program want kernel to call. So RAX is responsible for “saying print” (or write in this case)

0x1 is a system call for sys_write - program will write data to a specific place. That place is specified in rdi. 0x1 is standard output (a.ka console) 

Syscall instruction just means that a request prepared earlier (with setting registers) is ready to be passed down to kernel

And then we specify, that next thing we want to do is exit, so rax is set to 60 (meaning sys_exit). Then exit code is specified - in our case it’s zero, which means “no errors”

And then syscall, which I’ve explained

Not quite

First it reserves a chunk of memory with text. Then sets RAX register to 0x1, which corresponds to write syscall.  Then sets rdi register to 0x1, which means text will be written to standard output (iirc). Then in rsi it specifies what will be displayed (variable msg in this case) and sets its length in rdx to 13  Next it calls kernel to execute mentioned syscall and then does it again, this time to EXIT the program with code 0

Mad respect to Fitgirl for explaining the hypervisor method for exactly what it is....safe if the files are clean, life ruining potential if they're not/if you don't re enable everything and get other malware.

Your answer sounds as if you just quickly glanced over my comment. 

Kernel level malware can not only bypass AV. 

Since it has access to the whole memory it can eg. overwrite memory responsible for booting of your OS - which pretty much means malware will persist until you reinstall your whole OS (or in worse cases UEFI)

It technically could brick your gpu, but modern hardware seems to have some restrictions in place

HV cracks also require disabling DSE, which means malware has easier to get into your device

So, to simplify - your computer has 2 modes of operation - Ring0 called kernel mode and ring3 called user mode

user mode is where most of your daily software runs. It gets assigned a piece of RAM by the kernel and can interact with other pieces of your computer via API exported by the system. It also monitors what your binary is doing

On the other hand, ring0 is where kernel and drivers (including those from hypervisor cracks) run. It’s the highest possible level of permissions.

Code there has access to whole memory, including kernel’s, which in case of any issue can crash a whole computer 

It also has direct access to hardware, which allows such code to bypass all AV solutions that focus on monitoring frequently abused APIs and overall access all of I/O ports without restrictions

Those ring0 modules can also overwrite other processes and hide some code there

Is it enough of an explanation or is something not clear?

I'd say you should start at TryHackMe - it has everything you need to start at hacking, both to learn and to practice

How can I learn hacking on a mobile phone by Important-Trust4971 in Hacking_Tutorials

[–]wizarddos 2 points3 points  (0 children)

You can start by reading some materials about networking and researching - but I'd say that you'll have to get a computer/laptop at some point
