Hi everyone, my name is Peter Lindgren and I'm the Technical Director of Helldivers 2. I've been making games at Arrowhead since the Magicka days and I've been involved in every game we've released to date. I will do my best in this post to address the concerns and confusion that's come up recently regarding the choice of Anti-Cheat software in Helldivers 2. So, let's start off with the more urgent questions:

Is GameGuard a kernel-level / administrator-priviledge anti-cheat?
Yes, GameGuard is a "kernel-level", aka rootkit, anti-cheat. Most anti-cheat run at "kernel-level", especially all of the popular ones. It's unfortunately one of the more effective ways to combat cheating. There are some anti-cheat systems that can run in "user-mode," but they are much less effective and tend to be cracked very quickly, resulting in widespread cheating.

Microsoft has announced an extension to the Windows Defender System Guard which will allow it to also verify and guarantee integryity of systems at a UEFI BIOS level. Citing an increase in hardware and firmware-level attacks over the years, the extended protection functionality aims to guarantee protection across the entire hierarchy of a device, from firmware up through to cloud processing.

The UEFI scanner is a new component of the built-in antivirus solution on Windows 10 and gives Microsoft Defender ATP the unique ability to scan inside of the firmware filesystem and perform security assessment. Working in conjunction with your systems' chipset, the UEFI scanner features a three-pronged solution to firmware security: UEFI anti-rootkit, which reaches the firmware through Serial Peripheral Interface (SPI); Full filesystem scanner, which analyzes content inside the firmware; and a Detection engine, which identifies exploits and malicious behaviors.

Windows 8 implements a radical new user interface called Metro for desktop PC's, which has so far received a mixed reception. However, there's many other changes under the hood and one of those is how password security is handled, which we look at here. It's a fact of life, that in today's modern world, we have to remember a plethora of passwords and PIN's, which can be daunting. This leads to security issues as users end up writing down passwords and/or create very insecure ones which can be easily guessed. Windows 8 aims to uphold strong password security, while at the same time, easing the burden on the user. Also, passwords can be obtained in various ways by miscreants, such as phishing, keylogging, guessing, and cracking. Windows addresses each of these problems in three main ways:

There have been many accounts of Sony using rootkits in their products back since 2005. However, a new story claims Sony's biometric Micro Vault USM-F thumb drive includes a rootkit which can allow hackers to compromise your PC. The rootkit was first discovered and confirmed by McAfee researchers Aditya Kapoor and Seth Purdy who posted the founding on their blog.
