Recently we faced an issue, after upgrading some components, the game client was not able to start occasionally, we still can see the game client process in the taskmgr.exe when this bug occurred, but the UI did not show, and the game client has anti-debug components, we cannot use a debugger to debug it. so I’m gonna talk about how to use Application Verifier to find the root cause of this bug.

VSCode VS VIM + Ctags + Cscope!

In this article, I’m going to talk about how to use WPT(Windows Performance Toolkit) to analyze CPU problems of programs

Take a note of FreeRTOS analysis

Today i’m gonna show you how to bypass anti-debug and anti-vm of VMProtect(version before 3.2)

Overview

Take a note of some useful commands that are hard to remember!

Most of us may have used virtualbox or vmware, they have friendly UI and are easily to use, they run under a host OS, just like a normal software. but xen is different, xen runs directly on hardware, it is loaded by the bootloader before OS, then it loads the first special VM(dom0), dom0 has access to hardware, xen-tools are installed on dom0 used to communicate with xen hypervisor and manage other VMs, other VMs can’t access the hardware directly. in this article, i will tell you how to install xen-4.8 on debian9 64bit, and install a windows guest OS.

Today i find some code which was written by me years ago in my harddisk, and i suddenly want to upload it to github, anyway, it’s sort of a reminder of my past youth.

This is just a test for my first blog.
