![]() I will be using Parallels Desktop for Mac with Windows 7 and XP virtual machines for the tests. So, let’s see if there are some common cases when Windows goes to the black screen and if there’s any way to fix it. Needless to say, it took a while for me to do that, but now we’ve got some shiny screenshots and thorough instructions! How about that? In order to test a few fixes for the Windows black screen issue, I performed real tests with live configurations. Don’t rush to trash your poor virtual machine just yet-instead, we can try to fix it. Sound familiar? What can I say? That’s sad! But it’s not over. For instance: one of the worst-case scenarios is when Windows gives you the black screen. I could install special utilities, or just additional programs…īut this customization could result in some issues with the operating system. Sometimes I just add more RAM and CPU for the performance needs, or change the internal settings of the system. Once new software is installed on a Mac, some folks just start using it with the default settings, but others (and I’d say I’m one of them) optimize it by changing various settings. Some people are tech-savvy, and some aren’t. 2.Guest blog by Maria Golubeva, Parallels Support Team.The report concludes with recommendations and best practices to support your security strategy for a more ironclad defense against Emotet and other nefarious malware strains. Infrastructure is constantly shifting due to threat actors attempts to stay covert and maintain their C2 framework Its attacks serve multiple objectives and have become more prolific due to its wide range of infiltration tactics Shows evidence that attacking patterns are in continuous evolution Key highlights and takeaways for you from the Emotet research report: ![]() How to extract the recently updated Emotet configurationĬorrelating infection techniques and Emotet’s network infrastructure, revealing the agile-like software development lifecycle of Emotet How to create an Emotet sock puppet to fetch modules The report reveals never-before-exposed insights into Emotet, including a large-scale, detailed analysis of:Įmotet’s execution chains and their evolutionĮmotet’s multiple attack waves, campaigns, and network infrastructure Never-before-seen malware has infected hundreds of Linux and Windows devices Can admins get control of the revocation list? Sure, but then an attacker could also control the revocation. As the screenshot below shows, the driver loaded just fine." - Also, why can't we get a block list, or even better, a certificate revocation? Of course, if the driver is working as intended, and does not contain vulnerabilities and the key has not leaked, I supposed you wouldn't want to revoke it globally. The company claims that Windows users can enable a feature that automatically blocks known vulnerable drivers, but I was unable to make it work on my ThinkPad running the latest version of Windows 10, and as I'll get to shortly, Microsoft has no interest in helping me." Oh wait, nope: " turning on the combination of memory integrity and Hypervisor-protected code integrity will offer protection against BYOVD attacks, but at my request, Kálnai enabled both on a system running Windows 10 Enterprise, 4 and then attempted to load the vulnerable Dell driver exploited by Lazarus. ![]() Wait, could Microsoft fix this problem? - "Given the history, you might think that Microsoft would have created a viable defense to stop BYOVD attacks, but sadly there's no evidence that's the case.
