A new security bug has been discovered on Windows 8 and above which makes ASLR useless. The bug was discovered by a security researcher named Will Dormann. He explained the issue in a detailed post on CERT:

Learn more about ASLR Windows and the DEP security feature in this expert response, including how to turn on DEP and why ASLR bypass is a bad idea. Windows 8 and 10 contain optional features to forcibly enable ASLR on images not marked as ASLR compatible, and to randomize virtual memory allocations so that rebased images obtain a random base address. This is useful in the case where an EXE is ASLR compatible, but one of the DLLs it uses is not. A security feature bypass for Internet Explorer exists as a result of how exceptions are handled when dispatching certain window messages, allowing an attacker to probe the layout of the address space and thereby bypassing Address Space Layout Randomization (ASLR). By itself, the ASLR bypass does not allow arbitrary code execution. Windows 10, version 1607 Windows Server 2016 Windows 10 includes Group Policy-configurable “Process Mitigation Options” that add advanced protections against memory-based attacks, that is, attacks where malware manipulates memory to gain control of a system.

Both EMET and Windows Defender Exploit Guard enable system-wide ASLR without also enabling system-wide bottom-up ASLR. Although Windows Defender Exploit guard does have a system-wide option for system-wide bottom-up-ASLR, the default GUI value of “On by default” does not reflect the underlying registry value (unset). This causes programs without /DYNAMICBASE to get relocated, but without any entropy. The result of this is that such programs will be relocated, but to the same address every time across reboots and even across different systems.

For those who don’t know, Microsoft first implemented ASLR (Address Space Layout Randomization) in Windows Vista that helps prevent code-reuse attacks. ASLR uses a random memory address to execute code, but in Windows 8, Windows 8.1 and Windows 10 the feature is not always applied properly. In Windows 8, 8.1 and Windows 10, ASLR is not using random memory addresses, essentially rendering it useless.

Actually, with Windows 7 and EMET System-wide ASLR, the loaded address for eqnedt32.exe is different on every reboot. But with Windows 10 with either EMET or WDEG, the base for eqnedt32.exe is 0x10000 EVERY TIME.
Conclusion: Win10 cannot be enforce ASLR as well as Win7! pic.twitter.com/Jp10nqk1NQ

The good thing though is, Will shared a manual Registry Edit to fix the issue. For this, you need to do the following.

• Create a text file with the following:Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession Managerkernel]
  “MitigationOptions”=hex:00,01,01,00,00,00,00,00,00,00,00,00,00,00,00,00
• Save the file with Registry extension (.reg)
• Open Registry Editor by typing “regedit” in the Start Menu
• Select File>Import and choose the .reg file you just created.

This should be able to fix the issue until Microsoft sends an update to fix it completely.

10 Tips to Optimize Windows 10 for Gaming

In order to optimize PC for gaming Window 10, follow on the instructions below.

1. Optimize Windows 10 with Game Mode

As for how to improve gaming performance on Windows 10, you can optimize Windows 10 with Game Mode.

Now, here is the tutorial.

4. Upgrade to SSD

To optimize Windows 10 for gaming, you can choose to upgrade the hardware of your computer so that making your computer faster.

As for upgrade hardware and how to makes Windows 10 faster for gaming, you can choose to upgrade HDD to SSD. But please note that upgrading to SSD would not increase the performance directly, but it could speed up your Windows 10 and reduce the game loading time.

Hence, you can choose to upgrade HDD to SSD so as to improve computer performance.

To upgrade HDD to SSD without data loss, you can choose the clone tool – MiniTool ShadowMaker. It enables you to clone OS from HDD to SSD without data loss.

You can download MiniTool ShadowMaker from the following button or choose to purchase an advanced edition.

Now, we will show you how to upgrade HDD to SSD without data loss with MiniTool ShadowMaker.

1. Install MiniTool ShadowMaker and launch it.

2. Click Keep Trial.

4. After entering its main interface, go to the Tools page.

5. Then click Clone Disk to continue.

6. Next, click Source module to choose select the clone source. Here, you can choose the original system disk as the clone source. Then click Finish.

7. Click Destination module to choose the target disk. Here, you need to choose the SSD as the target disk. Then click Finish.

Then click OK.

All data on the target disk will be destroyed during the clone process. If you have important files on it, please back up them Then click Yes to continue.

The disk cloning process will begin. The time it takes depends on the number of files on the hard drive and please do not interrupt the cloning process.

When the disk clone process is finished, you will receive a warning message that informs you that the original hard drive and the target disk have the same signature. If both are connected to your computer, either of them will be marked as offline. In addition, if you want to boot your computer from the target disk, please change the BIOS setting first.
