Question malware detected Defender for Windows 10
Why did my Microsoft Defender detect a malicious file in AppData\Roaming\Secure\QtWebKit4.dll (Trojan:Win32/Wacatac.C!ml) during a full scan and the Kaspersky Free and Malwarebytes Free scans didn't detect it? Was it maliciously modifying, corrupting, or deleting various files on my PC before detection? I sent it to Virus Total, the hash: 935cd9070679168cfcea6aea40d68294ae5f44c551cee971e69dc32f0d7ce14b Inside the same folder as this DLL, there's another folder with a suspicious file, Caller.exe. I sent it to Virus Total, and only one detection from 72 antivirus programs was found, with the name TrojanPSW.Rhadamanthys. VT hash: d2251490ca5bd67e63ea52a65bbff8823f2012f417ad0bd073366c02aa0b3828
Device Stuck on Restart Screen After Update - Error Code: ATTEMPTED WRITE TO READONLY MEMORY
Hi everyone, I’m experiencing an issue with my Windows device that started after a recent update. For the past three days, my device has been stuck on a restart screen with the following error message: Your device ran into a problem and needs to restart. We'll restart for you. For more information about this issue and possible fixes, visit https://www.windows.com/stopcode If you call a support person, give them this info: Stop Code: ATTEMPTED WRITE TO READONLY MEMORY I’ve tried restarting the device multiple times, but it keeps returning to this screen. I’m unable to access my system or troubleshoot further. Has anyone else encountered this issue after an update? Any suggestions on how to resolve this would be greatly appreciated. Thank you in advance for your help!
Microsoft's recommendation regarding traffic inspection of m365 traffic
Hi, does anyone know, what is microsoft's official recommendation to prevent any attackers from distributing malware via microsoft's own cloud resources like discussed at https://www.theregister.com/2024/08/08/microsoft_google_cloud_storage_malware/? According to microsoft's networking principles, traffic related to Microsoft 365 shouldn't be inspected by any networking component and routed directly to microsoft (bypassing proxies and other traffic inspection solutions). How can this be configured safely, when there is such attack path?

Talk soon. -RodThis was my preparation for the exam Microsoft Certified: Cybersecurity Architect Expert (SC-100)!
Dear Microsoft 365 Security and Azure Security Friends, When I first read about this certification I was immediately excited! But at the same time I had a lot of respect, because it is an expert certification. I quickly started collecting information. The first thing I learned was that it takes a so-called prerequisite exam to become a Microsoft Certified: Cybersecurity Architect Expert certification. The following prerequisite exams are available (only one of these exams must be passed): Microsoft Certified: Security Operations Analyst Associate (SC-200) https://docs.microsoft.com/en-us/learn/certifications/security-operations-analyst/ Microsoft Certified: Identity and Access Administrator Associate (SC-300) https://docs.microsoft.com/en-us/learn/certifications/identity-and-access-administrator/ Microsoft Certified: Azure Security Engineer Associate (AZ-500) https://docs.microsoft.com/en-us/learn/certifications/azure-security-engineer/ Microsoft 365 Certified: Security Administrator Associate (MS-500) https://docs.microsoft.com/en-us/learn/certifications/m365-security-administrator/ I have taken all these prerequisite exams. The two exams AZ-500 and MS-500 helped me the most in preparing for the SC-100 (this is certainly not the case for everyone). In this SC-100 exam you will be quizzed on topics in Microsoft Sentinel, Microsoft Defender for Cloud, Microsoft 365 Defender for Cloud Apps (and all other Defender products), Azure Policy, Azure landing zone, etc. This spectrum is huge, please take enough time to "explore" these "portals" deeply. You don't have to have the technical knowledge down to the last detail. No not at all, in this exam it is important to use all the features and products with the right strategy. This was among other things my way to success! Now to my preparations for the exam: 1. First of all, I looked at the Exam Topics to get a first impression of the scope of topics. https://docs.microsoft.com/en-us/learn/certifications/cybersecurity-architect-expert/ Please take a close look at the skills assessed: https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RWVbXN 2. So that I can prepare for an exam I need an Azure test environment (this is indispensable for me). You can sign up for a free trial here. https://azure.microsoft.com/en-us/free/ Next, I set up a Microsoft 365 test environment. You can sign up for a free trial here. https://www.microsoft.com/en-us/microsoft-365/business/compare-all-microsoft-365-business-products I chose the "Microsoft 365 Business Premium" plan for my testing. I have also registered several free trials to test the various Defender products. 3. Now it goes to the Microsoft Learn content. These learn paths (as you can see below, all 4) I have worked through completely and "mapped"/reconfigured as much as possible in my test environment. https://docs.microsoft.com/en-us/learn/paths/sc-100-design-zero-trust-strategy-architecture/ https://docs.microsoft.com/en-us/learn/paths/sc-100-evaluate-governance-risk-compliance/ https://docs.microsoft.com/en-us/learn/paths/sc-100-design-security-for-infrastructure/ https://docs.microsoft.com/en-us/learn/paths/sc-100-design-strategy-for-data-applications/ 4. Register for the exam early. This creates some pressure and you stay motivated. https://docs.microsoft.com/en-us/learn/certifications/cybersecurity-architect-expert/ 5. Please also watch the video of John Savill, it is very helpful! https://youtu.be/2Qu5gQjNQh4 6. The Exam Ref for the SC-200 exam was also very supportive. https://www.microsoftpressstore.com/store/exam-ref-sc-200-microsoft-security-operations-analyst-9780137666720 7.

You can find a list of all the links here: https://github.com/tomwechsler/Microsoft_Cloud_Security/blob/main/SC-100/Links.md I know you've probably read and heard this many times: read the exam questions slowly and accurately. Well, that was the key to success for me. It's the details that make the difference between success and failure. Let me give you an example at this point. You want to make a business app available. The authentication should be done by each person with his own LinkedIn account. Which variant of Azure Active Directory do you use for this? At this point you should know the different types of Azure Active Directory. One final tip: When you have learned something new, try to explain what you have learned to another person (whether or not they know your subject). If you can explain it in your own words, you understand the subject. That is exactly how I do it, except that I do not explain it to another person, but record a video for YouTube! I hope this information helps you and that you successfully pass the exam. I wish you success! Kind regards, Tom Wechsler P.S. All scripts (#PowerShell, Azure CLI, #Terraform, #ARM) that I use can be found on github! https://github.com/tomwechslerNew Blog Post | Destructive malware targeting Ukrainian organizations
Destructive malware targeting Ukrainian organizations - Microsoft Security Blog Microsoft Threat Intelligence Center (MSTIC) has identified evidence of a destructive malware operation targeting multiple organizations in Ukraine. This malware first appeared on victim systems in Ukraine on January 13, 2022. Microsoft is aware of the ongoing geopolitical events in Ukraine and surrounding region and encourages organizations to use the information in this post to proactively protect from any malicious activity. While our investigation is continuing, MSTIC has not found any notable associations between this observed activity, tracked as DEV-0586, and other known activity groups. MSTIC assesses that the malware, which is designed to look like ransomware but lacking a ransom recovery mechanism, is intended to be destructive and designed to render targeted devices inoperable rather than to obtain a ransom.Detection and Response Team AMA Next Week!
