Turn off your VM and add following to vmx:

monitor_control.virtual_rdtsc = "false"
monitor_control.restrict_backdoor = "true"
isolation.tools.getPtrLocation.disable = "true"
isolation.tools.setPtrLocation.disable = "true"
isolation.tools.setVersion.disable = "true"
isolation.tools.getVersion.disable = "true"
monitor_control.disable_directexec = "true"

monitor_control.virtual_rdtsc = "false"

monitor_control.restrict_backdoor = "true"

isolation.tools.getPtrLocation.disable = "true"

isolation.tools.setPtrLocation.disable = "true"

isolation.tools.setVersion.disable = "true"

isolation.tools.getVersion.disable = "true"

monitor_control.disable_directexec = "true"

Tested on VMware Fusion + Windows XP.

Install Debian MIPS and Debian PowerPC on OSX

By @sskaje
Link: https://sskaje.me/2016/05/qemu-install-debian-mips-debian-powerpc-on-osx/

I tried MacPorts, but its qemu does not have qemu-system-ppc or qemu-system-mips. Even though, I have qemu installed under macports, if you see any dependency missing, try to port install qemu and then uninstall.

OSX 10.11.5
Xcode

Install QEMU

Download 2.6.0 from Qemu.org, configure and make like:

# ./configure --enable-cocoa --target-list=arm-softmmu,i386-softmmu,mips-softmmu,mips64-softmmu,ppc-softmmu,ppc64-softmmu,x86_64-softmmu
# make -j 8
# make install

# ./configure --enable-cocoa --target-list=arm-softmmu,i386-softmmu,mips-softmmu,mips64-softmmu,ppc-softmmu,ppc64-softmmu,x86_64-softmmu

# make -j 8

# make install

I did not see any error, Google if you see any.

Install Debian MIPS

Debian official installer only have netboot image. All you need is GOOD INTERNET CONNECTION, don’t download iso from debian cd mirror.

Prepare

Download vmlinux and initrd.

Install

Create Image

$ qemu-img create -f qcow2 disk.img 8G 
Formatting 'disk.img', fmt=qcow2 size=8589934592 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16

1 2	$ qemu-img create -f qcow2 disk.img 8G Formatting 'disk.img', fmt=qcow2 size=8589934592 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16

Install

$ qemu-system-mips -hda disk.img -kernel vmlinux-3.16.0-4-4kc-malta -initrd initrd.gz -nographic

1	$ qemu-system-mips -hda disk.img -kernel vmlinux-3.16.0-4-4kc-malta -initrd initrd.gz -nographic

Follow the instructions, almost same as debian x86/x86_64.
You may be asked to configure and mount partition, I picked one partition and choose ext4 and mount to /.

Now, you have to wait for a long long time…

Then:

   ┌─────────────────┤ [!] Continue without boot loader ├──────────────────┐
   │                                                                       │

Just continue.

Run

qemu-system-mips -hda disk.img -kernel vmlinux-3.16.0-4-4kc-malta -append "root=/dev/sda1" -nographic

1	qemu-system-mips -hda disk.img -kernel vmlinux-3.16.0-4-4kc-malta -append "root=/dev/sda1" -nographic

!!!REMEMBER!!!
NO -initrd
-append “root=/dev/sda1”
!!!/REMEMBER!!!

If you want to exit qemu under nographic:
press ctrl+a, then c (no ctrl), type quit, hit enter.

Install Debian PowerPC

Similar to MIPS, but debian provides cdrom installer.

vmlinux, initrd.gz

So,

Install:

 qemu-system-ppc  -kernel vmlinux -initrd initrd.gz -cdrom debian-8.4.0-powerpc-CD-1.iso -hda disk.img

1	qemu-system-ppc -kernel vmlinux -initrd initrd.gz -cdrom debian-8.4.0-powerpc-CD-1.iso -hda disk.img

Run:

You may see similar error message above saying quik loader failed to install, just ignore it.
And, for PowerPC, no -kernel and no -append is required.
You can also forward ssh to local loopback.

qemu-system-ppc -hda disk.img  -net user,hostfwd=tcp::10022-:22 -net nic -m 256

1	qemu-system-ppc -hda disk.img -net user,hostfwd=tcp::10022-:22 -net nic -m 256

Click Button and Read Text from Other Program on Windows

By @sskaje
Link: https://sskaje.me/2016/05/click-button-read-text-program-windows/

I have a protected application on windows, normally my clients have to run that program, click a button, copy some text from another text control, upload to somewhere…

I need to find a solution simulate button click and read the text control.

There are two buttons, generate and exit, and a text control.

Here is what I did in C++, build under Windows XP + Visual C++ 6.0/7.0 in CLI.

1 Run the program.

	STARTUPINFO si;
	PROCESS_INFORMATION pi;
	ZeroMemory(&si, sizeof(si));
	ZeroMemory(&pi, sizeof(pi));
	
	if (!CreateProcess(
		NULL,
		(LPTSTR)  "GetResult.exe",
		NULL,
		NULL,
		false,
		CREATE_NO_WINDOW,
		NULL,
		NULL,
		&si,
		&pi
	)) {
		DWORD errval = GetLastError();
		cout << "CreateProcess Failed: " << errval << endl;
		return 2;
	}

	Sleep(500);

STARTUPINFO si;

PROCESS_INFORMATION pi;

ZeroMemory(&si, sizeof(si));

ZeroMemory(&pi, sizeof(pi));

if (!CreateProcess(

NULL,

(LPTSTR) "GetResult.exe",

NULL,

false,

CREATE_NO_WINDOW,

NULL,

&si,

&pi

)) {

DWORD errval = GetLastError();

cout << "CreateProcess Failed: " << errval << endl;

return 2;

}

Sleep(500);

Sleep is required here, to ensure that you can find correct control.

2 Find controls

	int ctrlBtnGet = 0x01;
	int ctrlTxtResult = 0x03e8;
	int ctrlBtnExit = 0x02;

	HWND wGetWindow = FindWindow(0, "Window Title");	
	HWND wBtnGet = GetDlgItem(wGetWindow, ctrlBtnGet);
	HWND wBtnExit = GetDlgItem(wGetWindow, ctrlBtnExit);	
	HWND wTxtResult = GetDlgItem(wGetWindow, ctrlTxtResult);

int ctrlBtnGet = 0x01;

int ctrlTxtResult = 0x03e8;

int ctrlBtnExit = 0x02;

HWND wGetWindow = FindWindow(0, "Window Title");

HWND wBtnGet = GetDlgItem(wGetWindow, ctrlBtnGet);

HWND wBtnExit = GetDlgItem(wGetWindow, ctrlBtnExit);

HWND wTxtResult = GetDlgItem(wGetWindow, ctrlTxtResult);

These CtrlID can be read by many *Spy app on windows.

3 Perform click and read from text control

In my case, Sleep is also required after BM_CLICK was sent to target program, otherwise I may have to click more than once.
So, I wrote a loop

	int max_retry = 5;
	
	int retry = 0;
	
	int length;
	char buf[2048] = {0};
	
	do {
		SendMessage(wBtnGet, BM_CLICK, 0, 0);
		Sleep(300);
	
		length = (int) SendMessage(wTxtResult, WM_GETTEXTLENGTH, 0, 0);
		
		if (length > 0) {
			SendMessage(wTxtResult, WM_GETTEXT, sizeof(buf) / sizeof(buf[0]), (LPARAM) buf);
			printf("%s\n", buf);
			break;
		}
		
	} while (++retry < max_retry);

int max_retry = 5;

int retry = 0;

int length;

char buf[2048] = {0};

do {

SendMessage(wBtnGet, BM_CLICK, 0, 0);

Sleep(300);

length = (int) SendMessage(wTxtResult, WM_GETTEXTLENGTH, 0, 0);

if (length > 0) {

SendMessage(wTxtResult, WM_GETTEXT, sizeof(buf) / sizeof(buf[0]), (LPARAM) buf);

printf("%s\n", buf);

break;

}

} while (++retry < max_retry);

I tried GetDlgItemText and GetWindowText, neither of these two works to get text from the control.
WM_GETTEXTLENGTH and then WM_GETTEXT is the best choice so far as I know.

4 Click Exit

	SendMessage(wBtnExit, BM_CLICK, 0, 0);

1	SendMessage(wBtnExit, BM_CLICK, 0, 0);
