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
Azure AD PIM token lifetimes
Does anyone know if Azure AD PIM has any impact on token lifetimes? I know an access token remains valid for 1 hour whereas a refresh token can have long life. Does this mean if user activates their role for only 30mins, they will continue to have privileged access for at least one hour unless user explicitly logs-out of the session.Want to earn an Exclusive Security Tech Community Badge?

Hunting for MFA manipulations in Entra ID tenants using KQL
The following article, Hunting for MFA manipulations in Entra ID tenants using KQL proved to be an invaluable resource in my search for an automated way to notify users of MFA modifications. I've adapted the KQL query to function within Defender Advanced Hunting or Azure Entra, my objective is to establish an alert that directly E-Mails the affected user, informing them of the MFA change and advising them to contact security if they did not initiate it. While the query runs correctly under Defender Advanced Hunting, I'm currently unable to create a workable custom alert because no "ReportId" is being captured. Despite consulting with Copilot, Gemini, CDW Support, and Microsoft Support, no workable solution has been achieved. Any insight would be greatly appreciated - Thank You! //Advanced Hunting query to parse modified: //StrongAuthenticationUserDetails (SAUD) //StrongAuthenticationMethod (SAM) let SearchWindow = 1h; let AuthenticationMethods = dynamic(["TwoWayVoiceMobile","TwoWaySms","TwoWayVoiceOffice","TwoWayVoiceOtherMobile","TwoWaySmsOtherMobile","OneWaySms","PhoneAppNotification","PhoneAppOTP"]);

Authenticator not displaying numbers on MacOS
I'm have an issue with MFA on a Mac (all the latest versions). We have conditional access policies in place, so once a day I'm prompted for MFA (I work off-site) and the Office app (e.g. Outlook, Teams) will create the pop-up window that 'should' display a number that I then match on my phone. My phone see's the push notification, but the Mac never creates the numbers in the first place. The pop-up is there, just no number. The workaround is: Answer 'its not me' on the phone On the Mac, select 'I can't use Authenticator right now' Tell the Mac to send a new request This time it creates the number and I can authenticate on the phone. It only appears to happen for the installed Office applications i.e. if I'm accessing applications/admin-centre via the browser, then the pop-up is within the browser and everything works first time. Is this a known issue?Meet Your New Cybersecurity Sidekick - Microsoft Security Copilot Agents
Imagine if your security team had a super-smart assistant that never sleeps, learns from every task, and helps stop cyber threats before they become disasters. That’s exactly what Microsoft’s new Security Copilot Agents are designed to do. Why Do We Need Them? Cyberattacks are getting sneakier and faster many now use AI to trick people or break into systems. In fact, 67% of phishing attacks in 2024 used AI. Meanwhile, security teams are drowning in alerts 66 per day on average and 73% of experts admit they’ve missed important ones. That’s where Security Copilot comes in. It’s like having an AI-powered teammate that helps you investigate threats, fix issues, and stay ahead of attackers. What Are Security Copilot Agents? Think of these agents as mini digital coworkers. They’re not just chatbots they’re smart, adaptable tools that: Learn from your feedback Work with your existing Microsoft security tools Help you make faster, better decisions Keep you in control while they handle the heavy lifting They’re built to be flexible and smart unlike traditional automation that breaks when things change. Real-World Examples of What They Do Here are a few of the agents already available: Phishing Triage Agent: Automatically checks if a suspicious email is a real threat or just spam. It explains its reasoning in plain language and learns from your feedback. Alert Triage Agents (in Microsoft Purview): Helps prioritize which security alerts matter most, so your team can focus on the big stuff first. Conditional Access Optimization Agent (in Microsoft Entra): Keeps an eye on who has access to what and flags any gaps in your security policies. Vulnerability Remediation Agent (in Microsoft Intune): Spots the most urgent software vulnerabilities and tells you what to fix first. Threat Intelligence Briefing Agent: Gives you a quick, customized report on the latest threats that could affect your organization. Even More Help from Partners Microsoft is also teaming up with other companies to build even more agents. For example: OneTrust helps with privacy breach responses. Tanium helps analysts make faster decisions on alerts. Fletch helps reduce alert fatigue by showing what’s most important. Aviatrix helps diagnose network issues like VPN or gateway failures. BlueVoyant: helps to assess your SOC and recommends improvements. Why It Matters These agents don’t just save time they help your team stay ahead of threats, reduce stress, and focus on what really matters. They’re like having a team of AI-powered interns who never get tired and are always learning.
