User app registration - exploitable for BEC?
Hello. Recently dealt with a case of BEC. I'm not trained in forensics, but doing my best. Appears the hacker used an application called eM Client for their attack, getting access to a user's mailbox and hijacking a thread. I can see the login from two weeks ago (the incident was only noticed a couple days ago, however) - from a European country that SHOULD have been blocked by Conditional Access. Come to find out, the tenant conditional access was unassigned from everyone. We're not sure how - we re-enabled it, and audited changes, but the only change that appears was us re-enabling it. Which I thought indicates it was never configured right, except we've got a ticket documenting a change to Conditional Access a couple days after the hack that ALSO does not appear in the logs. So... it's likely it was changed, yet I have no record of that change (atleast, not through Entra > Monitoring > Auditing). If anyone knows any other ways of checking this, please advise - but I can't seem to even access our Diagnostic settings, the page tells me I need an Azure Active Directory subscription (I'm on Entra ID P1, which includes AAD.... this might be related to being global admin, and not Security Admin - we don't use that role in this relationship) ANYWAY, my amateur forensic skills have found that the attacker used an app called eM Client to get access. I'm not sure yet how they obtained the password, and got past MFA... But quick research shows this application (esp it's pro version) is known for use in BEC. The app was registered in Entra, and granted certain read permissions in Entra ID for shared mailboxes, presumably to find a decent thread to hijack. I'm not 100% sure yet there was any actual exploit done using this app, but it's popularity amongst hackers implies it does SOMETHING useful (i think remember that it authenticates using Exchange Web Services instead of Exchange Online, or something similar? Will update when I have the chance to check). We're in the process of improving our Secure Score, and this incident makes me think user's ability to register apps should be locked down. Checked Secure Score for this, and while there ARE recommendations around apps, disabling user app registration is NOT one of them. Just curious about people's thoughts. I just barely understand App Registration in Entra, but if this is a known attack vector, I would think disabling app registration would be a security recommendation?
Secure Score Improvement Recommended actions information sheet
Hello All I am starting a project to Improve our Secure score following the "Recommended Actions" section in the M365 Defender portal. Now each action comes with its own set of General information and remediation options. Rather than get the actions on each of the 208 recommendations by clicking through all the tabs and recording every step required to complete the recommendation , does anyone know if Microsoft has an Excel sheet with all the relevant Secure Score Improvement actions/information in one place? Will make running this project so much easier! Thanks in advance ! Kind Regards Christo
Secure Score - Secure Home Folders in macOS
I've performed the recommended manual remediation action (sudo chmod -R og-rw /Users/) on my Macs but Secure Score doesn't recognize it. I have noticed this occurring for a few item. We have also remediated some things through InTune but still seem to have no movement on the SecureScore. Is this a glitch within or am I missing something altogether. ThanksUnlock Proactive Defense: Microsoft Security Exposure Management Now Generally Available
As the digital landscape grows increasingly interconnected, defenders face a critical challenge: the data and insights from various security tools are often siloed or, at best, loosely integrated. This fragmented approach makes it difficult to gain a holistic view of threats or assess their potential impact on critical assets. In a world where a single compromised asset can trigger a domino effect across connected resources, thinking in graphs has become essential for defenders. This approach breaks down silos, allowing them to visualize relationships between assets, vulnerabilities, and threats, ultimately enabling proactive risk management and strengthening their stance against attackers. Traditional vulnerability management is no longer sufficient. While patching every potential weakness might seem like a solution, it's neither practical nor effective. Instead, modern security strategies must focus on the exposures that are easiest for attackers to exploit, prioritizing vulnerabilities that present the greatest risk. This shift marks the evolution of vulnerability management into what we now call exposure management. Earlier this year, we launched Microsoft Security Exposure Management in public preview, introducing defenders to powerful foundational capabilities for holistic exposure management. Backed by extensive threat research and Microsoft’s vast visibility into security signals, these tools provide coverage for commonly observed attack techniques. Exposure Management includes Attack Surface Management, Attack Path Analysis, and Unified Exposure Insights— solutions that offer security teams unmatched visibility and insight into their risk landscape. Attack Surface Management offers a complete, continuous view of an organization’s attack surface, enabling teams to fully explore assets, uncover interdependencies, and monitor exposure across the entire digital estate. Central to this is the identification of critical assets, which are often prime targets for attackers. By highlighting these key assets, security teams can prioritize their efforts and better understand which areas require the most protection. By giving security teams a clear map of their exposure points, Attack Surface Management empowers a more informed and comprehensive defense strategy. Attack Path Analysis takes this a step further, guiding teams in visualizing and prioritizing high-risk attack paths across diverse environments, with a specific focus on critical assets. This capability allows for targeted, effective remediation of vulnerabilities that impact these key assets, helping to significantly reduce exposure and the likelihood of a breach by focusing on the most impactful pathways an attacker might exploit. Unified Exposure Insights gives decision-makers a clear view of an organization's threat exposure, helping security teams address key questions about their posture. Through Security Initiatives, teams focus on priority areas like cloud security and ransomware, supported by actionable metrics to track progress, prioritize risks, and align remediation with business goals for proactive risk management. Exposure Management translates vulnerabilities and exposures into more understandable language about risk and actionable initiatives related to our environment, which helps stakeholders and leadership grasp the impact more clearly. - Bjorn Pauwels Cyber Security Architect Atlas Copco Throughout the public preview, we collaborated closely with customers and industry experts, refining Microsoft Security Exposure Management based on real-world usage and feedback. This partnership revealed that the biggest challenges extended beyond deploying the right tools; they involved enhancing organizational maturity, evolving processes, and fostering a proactive security mindset. These insights drove strategic enhancements to features and user experience, ensuring the solution effectively supports organizations aiming to shift from reactive to proactive threat management. For example, several organizations created a 'RiskOps' role specifically to champion cross-domain threat exposure reduction, breaking down silos and unifying teams around common security goals. Security Operations (SecOps) teams now report significantly streamlined processes by leveraging asset criticality in incident prioritization, helping them address the most impactful threats faster than previously possible. Likewise, vulnerability management teams are using enhanced attack map and path analysis features to refine patching strategies, focusing more precisely on vulnerabilities most likely to lead to real risks. These examples underscore Exposure Management's ability to drive practical, measurable improvements across diverse teams, empowering them to stay ahead of evolving threats with a targeted, collaborative approach to risk management. Exposure Management enables organizations to zero in on their most critical exposures and act quickly. By breaking down silos and connecting security insights across the entire digital estate, organizations gain a holistic view of their risk posture. This comprehensive visibility is crucial for making faster, more informed decisions—reducing exposure before attackers can exploit it. We are excited to announce the general availability of Microsoft Security Exposure Management This release includes several new capabilities designed to help you build and enhance a Continuous Threat Exposure Management (CTEM) program, ensuring that you stay ahead of threats by continuously identifying, prioritizing, and mitigating risks across your digital landscape. Global rollout started 19 Nov, 2024 so keep an eye out for Exposure Management in your Defender portal, https://security.microsoft.com Cyber Asset Attack Surface Management To help you establish a comprehensive, single source of truth for your assets, we are expanding our signal collection beyond Microsoft solutions to include third-party integrations. The new Exposure connectors gallery offers a range of connectors to popular security vendors. Data collected through these connectors is normalized within our exposure graph, enhancing your device inventory, mapping relationships, and revealing new attack paths for comprehensive attack surface visibility. Additional insights like asset criticality, internet exposure and business application or operational affiliation are incorporated from the connected tools to enrich the context that Exposure Management can apply on the collected assets. This integrated data can be visualized through the Attack Map tool or explored using advanced hunting queries via KQL (Kusto Query Language). External data connectors to non-Microsoft security tools are currently in public preview, we are continuously working to add more connectors for leading market solutions, ensuring you have the broadest possible visibility across your security ecosystem. Discover more about data connectors in our documentation. Extended Attack Path Analysis Attack Path Analysis provides organizations with a crucial attacker’s-eye perspective, revealing how adversaries might exploit vulnerabilities and move laterally across both cloud and on-premise environments. By identifying and visualizing potential paths – from initial access points, such as internet-exposed devices, to critical assets – security teams gain valuable insight into the paths attackers could take, including hybrid attack paths that traverse cloud and on-prem infrastructure. Microsoft Security Exposure Management addresses the challenge of fragmented visibility by offering defenders an integrated view of their most critical assets and the likely routes attackers might exploit. This approach moves beyond isolated vulnerabilities, allowing teams to see their environment as a connected landscape of risks across hybrid infrastructures, ultimately enhancing their ability to secure critical assets and discover potential entry points. We are excited to update on our solution’s latest enhancement, which includes a high-level overview experience, offering a clear understanding of top attack scenarios, entry points, and common target types. Additionally, Exposure Management highlights chokepoints with a dedicated experience – these chokepoints are assets that appear in multiple attack paths, enabling cost-effective mitigation. Chokepoints also support blast radius querying, showing how attackers might exploit these assets to reach critical targets. In addition, we are adding support for new adversarial techniques including: DACL Support: We now include Discretionary Access Control Lists (DACLs) in our attack path analysis, through which more extensive attack paths are uncovered, particularly those that exploit misconfigurations or excessive permissions within access control lists. Hybrid Attack Paths: Our expanded analysis now identifies hybrid attack paths, capturing routes that originate on-premises and extend into cloud environments, providing defenders with a more complete view of potential threats across both infrastructures. In essence, attack path management allows defenders to transform isolated vulnerabilities into actionable insights across hybrid infrastructures. This comprehensive perspective enables security teams to shift from reactive to proactive defense, strengthening resilience by focusing on the most critical threats across their entire environment. Unified Exposure Insights With Microsoft Security Exposure Management, organizations can transform raw technical data into actionable insights that bridge the gap between cybersecurity teams and business decision-makers. By offering clear, real-time metrics, this platform answers key questions such as "How secure are we?", "What risks do we face?", and "Where should we focus first to reduce our exposure?" These insights not only provide a comprehensive view of your security posture but also guide prioritization and remediation efforts. To help your organization embrace a proactive security mindset, we introduced Security Initiatives—a strategic framework to focus your teams on critical aspects of your attack surface. These initiatives help teams to scope, discover, prioritize, and validate security findings while ensuring effective communication with stakeholders. Now, we are enhancing these capabilities to offer even greater visibility and control. The expanded initiative catalog now features new programs targeting high-priority areas like SaaS security, IoT, OT, and alongside existing domain and threat-focused initiatives. Each initiative continues to provide real-time metrics, expert-curated recommendations, and progress tracking, empowering security teams to drive maturity across their security programs. With this expanded toolset, organizations can further align their security efforts with evolving risks, ensuring a continuous, dynamic response to the threat landscape. SaaS Security Initiative (Powered by Microsoft Defender for Cloud Apps): Effective SaaS posture management is essential for proactively preventing SaaS-related attacks. The SaaS Security initiative delivers a comprehensive view of your SaaS security coverage, health, configuration, and performance and consolidates all best-practice recommendations for configuring SaaS apps into measurable metrics to help security teams efficiently manage and prioritize critical security controls. To optimize this initiative, activate key application connectors in Defender for Cloud Apps, including Microsoft 365, Salesforce, ServiceNow, GitHub, Okta, Citrix ShareFile, DocuSign, Dropbox, Google Workspace, NetDocuments, Workplace (preview), Zendesk, Zoom (preview), and Atlassian. For more information, check out https://aka.ms/Ignite2024MDA OT Security Initiative (Powered by Microsoft Defender for IoT): The convergence of Operational Technology (OT) and Information Technology (IT) has transformed industries worldwide, but it has also introduced significant new security challenges, particularly for industrial operations and critical infrastructure. The modern threat landscape, now accelerated by the growing capabilities of AI, demands specialized security solutions for these sensitive environments. The OT Security Initiative addresses these challenges by providing practitioners with a comprehensive solution to identify, monitor, and mitigate risks within OT environments, ensuring both operational reliability and safety. By leveraging Microsoft Defender for Endpoint discovery, the initiative offers unified visibility across enterprise and OT networks, empowering organizations to identify unprotected OT assets, assess their risk levels, and implement security measures across all physical sites. Enterprise IoT Security Initiative (Powered by Microsoft Defender for IoT): This initiative delivers comprehensive visibility into the risks associated with IoT devices within the enterprise, enabling organizations to assess their resilience against these emerging threats. As IoT devices frequently connect to endpoints, one another, or the internet, they become prime targets for cyberattacks. Therefore, businesses must continuously monitor the security of these devices, tracking their distribution, configuration, connectivity, exposure, and behavior to prevent the introduction of hidden vulnerabilities. By leveraging this initiative, organizations can proactively manage IoT risks and safeguard their digital landscape. Proactively understand how system updates affect scores The new versioning feature offers proactive notifications about upcoming version updates, giving users advanced visibility into anticipated metric changes and their impact on related initiatives. A dedicated side panel provides comprehensive details about each update, including the expected release date, release notes, current and updated metric values, and any changes to related initiative scores. Additionally, users can share direct feedback on the updates within the platform, fostering continuous improvement and responsiveness to user needs. Exposure History With the new history-reasoning feature, users can investigate metric changes by reviewing detailed asset exposure updates. In the initiative's history tab, selecting a specific metric now reveals a list of assets where exposure has been either added or removed, providing clearer insight into exposure shifts over time. Unified Role-Based Access Control (URBAC) Support We are excited to introduce the capability to manage user privileges and access to Microsoft Security Exposure Management through custom roles within the Microsoft Defender XDR Unified Role-Based Access Control (URBAC) system. This enhancement ensures higher productivity and efficient access control on a single, centralized platform. The unified RBAC permissions model offers administrators an alternative to Entra ID directory roles, allowing for more granular permission management and customization. This model complements Entra ID global roles by enabling administrators to implement access policies based on the principle of least privilege, thereby assigning users only the permissions they need for their daily tasks. We recommend maintaining three custom roles that align with organizational posture personas: Posture Reader: Users with read-only access to Exposure Management data. Posture Contributor: Users with read and manage permissions, enabling them to handle security initiatives and metrics, as well as manage posture recommendations. Posture Admin: Users who likely already hold higher-level permissions within the Microsoft Defender portal and can now perform sensitive posture-related actions within Exposure Management experiences.

I have registered a customer Secure Score for at least 6 months. Suddenly the score dropped from about 92% to 84% and checking the history looks like we never met the score above 90% but we have evidence of it including weekly meetings registering the score with a close follow up. I need that Microsoft explain how the score has dropped if we don't have regressed points, and don't matter if regressed since the history has been changed for the past months and we can't recover more than 6 months. I understand that daily we have new Items allocated to secure score, but how is that possible that it changes without history register? I need this explanation since I can't see any possible reason instead Microsoft Bug at Secure Score tool.
How much time does it takes to update secure score on Defender portal?
Hi Folks, I have marked some of the recommended actions on secure score as "third party" or "alternate mitigation". Even after 10 hours I can see action is still marked as "to be addressed". How much time does it take for changes to show up there? And also, how much time will it take to get this add up to my cumulative secure score?Outgoing mail is considered spam
Hi, I have a user in our tenant who sends emails to multiple people at one time. The maximum number is 200 recipients at a time per day. This concerns 1 email with, for example, 200 recipients. Now, after the email has been sent, this user is marked as Spam and the account is blocked. When I then look at the reason, it says Domain reputation. The user also remains within Microsoft's sent limits. How can I find out or where can I within O365 what the exact reason is why this user is blocked and the email is considered spam. There are several users who do this and do not receive any notifications. Can someone help me with this? Kind regards, Jacob
