Block Anonymous Access to Teams without GSA
Documentation states that anonymous access to Teams and Sharepoint can be blocked on the data plane with TrV2 through GSA. Testing TrV2 with a browser extension (Modheader) to inject the TrV2 header I found that injecting this header also to "data plane", ie Teams.microsoft.com does block anonymous access to Teams. I am wondering if this method could be safely used to block anonymous access to specific M365 service until a potential move to GSA
Get Custom Details from Sentinel
How do I go about getting the custom details set using https://learn.microsoft.com/en-us/azure/sentinel/surface-custom-details-in-alerts using REST API? I need to do this outside of logic app and using REST API. The incidents API endpoint doesn’t provide this detail and I couldn’t find any API endpoint listed in https://learn.microsoft.com/en-us/rest/api/securityinsights/operation-groups?view=rest-securityinsights-2024-01-01-preview that would allow me get to get the custom details with the values. Is there a sentinel or a graph API endpoint that’ll allow for me to get this information?
Blocking TCP 3389 - issues?
There is a strong push here to block RDP over part of our network. MSDI uses 3389 for name resolution. What order does MSDI use the three available methods for name resolution - TCP 135 (NTLM), UDP 137 (NetBIOS) and TCP 3389 (RDP)? We are currently seeing a lot of 3389 network traffic from the MSDI sensors to clients. TIA.Attack Simulation - Copy to SOC Mailbox
Hello Community! Currently we are using Knowbe4 to simulate phishing campaigns. We are evaluating the Microsoft E5 Attack simulation. One problem that I cannot figure out with the MSFT version is as follows: I have the SOC mailbox setup to send phishing emails to a shared mailbox for triage (I have it setup to not forward to Microsoft) When I create an attack simulation, and folks report the phish, I still get a copy of it in the phishing mailbox (I send these out monthly to thousands of people so I would prefer not to have a copy) I have looked at the email headers, and there is nothing in them that I can create a custom rule for. Has anyone been able to filter out attack simulation emails, while still receiving normal user reported emails in the SOC mailbox? Any advice appreciated. EmAzure Sentinel Training Lab solution is no longer on Azure Marketplace
Hi folks! It appears the Azure Sentinel Training Lab solution is no longer on Azure Marketplace. Was this removed for SFI security reasons and if so what are alternative deployments for this? https://github.com/Azure/Azure-Sentinel/tree/master/Solutions/Training/Azure-Sentinel-Training-Lab
Params required for Secure Score not available - AntiPhishPolicy
I have a pwsh script to configure the various threat protection policies. Has worked great. Went to run it on one tenant today, and got a number of invalid param errors. I investigated, and found that 1) The online portal doesn't list these params, they can't be set. Ex: EnableMailboxIntelligenceProtection, MailboxIntelligenceProtectionAction, EnableSimilarDomainsSafetyTips, etc They have a recommendation to configure Mailbox Protection to send to the Junk Mail folder (like everyone, which is what I've been doing for everyone). But this isn't an option for this tenant. Not on the web, or via ExchangeOnlineManagement. ``` PS C:\Users\me> Set-AntiPhishPolicy -EnableMailboxIntelligenceProtection $true Set-AntiPhishPolicy : A parameter cannot be found that matches parameter name 'EnableMailboxIntelligenceProtection'. ``` However, when I run Get-AntiPhishPolicy, those params DO return. A number of which I just can't set, but ARE Secure Score recommendations. EnableMailboxIntelligenceProtection : False EnableTargetedDomainsProtection : True EnableFirstContactSafetyTips : False EnableSimilarDomainsSafetyTips : False TargetedUserProtectionAction : Quarantine TargetedUserQuarantineTag : DefaultFullAccessPolicy MailboxIntelligenceProtectionAction : NoAction MailboxIntelligenceQuarantineTag : DefaultFullAccessPolicy TargetedDomainProtectionAction : NoAction TargetedDomainQuarantineTag : DefaultFullAccessPolicy AuthenticationFailAction : Quarantine SpoofQuarantineTag : DefaultFullAccessPolicy EnableSpoofIntelligence : True Furthermore, though this may be a temporary thing, I am unable to save any changes to the available params in the web console.Microsoft Security Fun Friday Week 3!

When we try to delete a Purview Records Management > File Plan label (or Data Lifecycle Management > Retention label), we get the following error: "You can't delete this record label because it's currently applied to items in your organization. You can use content explorer to determine which items have this label applied." (see attached image). When we go to content explorer to find the label (in this example, Bank Reconciliations), it doesn't appear to exist (see attached image). We also reviewed our Label policies and Retention policies, and the given labels are not associated with any policy that we can see. So, in result, we cannot clean up File Plan labels since we can't find and remove the association between them and policies / items. Has anyone encountered this error when deleting file plan retention labels, but then unable to find anything the label is associated with?
Suspected identity theft (pass-the-ticket) when switching LAN/WiFI
Hi, I see this alert "Suspected identity theft (pass-the-ticket)" when a user switches from LAN to WiFi or back. The laptop's DNS record has both IP addresses. I'm guessing Defender still thinks a different device is using the same Kerberos ticket. How do you deal with that? Can you tune the alert somehow so that doesn't keep alerting? Jan 16, 2025 4:15 PM This Kerberos ticket was first observed on 1/16/25 4:15 PM on [Device Name] (Laptop IP1). Jan 16, 2025 4:57 PM - Jan 16, 2025 4:57 PM [Username] accessed [Server Name] (CIFS) from [Server IP] (Laptop IP2). Thanks for your supportNew Blog Post | Migrating from Windows Information Protection to Microsoft Purview
By Edwin Chan Introduction In July 2022 we announced the sunsetting here: Announcing the sunset of Windows Information Protection (WIP) - Microsoft Community Hub of Windows Information Protection (WIP). The last version of windows to ship with WIP will be Win11 24H2, it will be the first version to not include WIP. However, the decryption capabilities will remain. Why are we doing this? Windows Information Protection, previously known as Enterprise Data Protection (EDP), was originally released to help organizations protect enterprise apps and data against accidental data leaks without interfering with the employee experience on Windows. Over time, many of you have expressed a need for a data protection solution that works across heterogenous platforms, and that allows you to extend the same sensitive data protection controls on endpoints that you have for the various SaaS apps and services you rely upon every day. To address these needs, Microsoft has built Microsoft Purview Data Loss Prevention (DLP), which is deeply integrated with Microsoft Purview Information Protection to help your organization discover, classify, and protect sensitive information as it is used or shared. What scenarios are in scope? WIP provided customers with the following key capabilities: Extend data protection to managed and unmanaged devices Protect enterprise data at rest when it's stored on a protected device Restrict which apps, removable drives, printers, network shares, and sites are allowed or restricted from copying, accessing, and storing sensitive data Classify data based upon the app or site where it was created, copied, or downloaded. Granular controls to designate different levels of data access restrictions Remote wipe sensitive data at rest How does deprecation impact WIP users? WIP as an offering is no longer under active feature development. The sunset process will follow the standard Windows client feature lifecycle, which shows which existing features and capabilities are supported and for what timelines. This was announced in July here. Following this deprecation announcement, the Microsoft Endpoint Manager team announced ending support for WIP without enrollment scenario by EOY 2022, which only impacts unmanaged devices. The announcement by the Microsoft Endpoint Manager team is here. Please visit the Microsoft Endpoint Manager announcement for the latest on the decommissioning of MEM’s support for the ‘unenrolled’ scenario. How should you respond to the deprecation notice? If you are using WIP without enrollment, Microsoft will be communicating with you directly about the impact to your devices and the timelines for that impact. Please keep an eye on the message center for the latest updates. Microsoft Endpoint Manager will continue to support WIP with enrollment (managed devices) scenarios for the duration of the OS lifecycle (until 2026) and will continue to offer options to enroll both corporate and personal devices for management (and subsequently to receive WIP policy). How do I start planning for this change? Refer to this chart for a breakdown of WIP capabilities and how they map to Purview: Read the full post here: Migrating from Windows Information Protection to Microsoft Purview
Global Administrator MFA recovery not possible
Since Microsoft automatically enforced MFA on administrator role in Azure you can end up in the situation where it is no longer possible to recover your tenant. If your only account on that tenant is with Global Administrator role and you accidentally loose your MFA, the only way is to call Microsoft support. Support on the phone is automated where any question regarding Azure is redirected to visit Azure portal. If your only user cannot login then Azure portal is not accessible.
Attack simulation Payload editor - recently broken?
Hello, Just last Wednesday, Jan. 8th, I created a new custom payload and was happy with the testing of the email. I logged in today and noticed that a majority of the formatting had been removed. I found this post: https://answers.microsoft.com/en-us/msoffice/forum/all/phishing-attack-simulation-payload-editor-is/88232e12-9744-4d87-9566-3fd5d8c2ed3a Seems like he is having the same issue I am facing. Nothing is centering and many of the blocks I have created are gone (ie the External email, banner). Anyone else having these issues or has anyone found a way to "fix" it. Here is a snip of the same payload, one sent Wednesday, the other Monday: Monday, Jan. 13th: Any help would be appreciated.Get $25 USD for reviewing a Microsoft Security product on Gartner Peer Insights in 2025

Hi everyone, I was just marveling about the addition of custom regulations in Compliance manager but apparently very few users seem to be using this particular module in Purview , at least I can't seem to find any user forum for it. Can anyone point me in the right direction or am I the only user of Compliance manager in the know universe 🙃 Regards, GuðjónAuthenticator 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?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?
