It absolutely does. I was just like you. There is always a way to domain admin. Nobody ever said don't protect your endpoints if you're not in the cloud. You protect them the same way you do if they are hybrid joined, just using a different technology. I helped build a cloud native org. We implemented STIGs on all our endpoints. They all had the slew of security point solutions too: SASE, EDR, Endpoint DLP, Insider Threat, ASR, etc. What I'm talking about has nothing to do with Entra. It's about moving employee devices out of AD to reduce attack surface because they don't need to be there and it reduces an incredible amount of attack surface. This has been a recommended best practice for a couple years now since Secure Future Initiative. Let me ask you something: How many times have you gotten domain admin or global admin from a device that was unable to talk to Active Directory? Active Directory is legacy and highly insecure in every organization I've consulted with. I thought security people were supposed to help people get off legacy and follow documented best practices? The reality with configuration based security improvements on-prem is not just that they are expensive. It's that the CIA triad includes availability and pentesters don't appreciate the services that get taken down in Sev1 and Sev2 incidents or degraded when you have to try to fix things on-prem. It's easy to say in a report, much harder to achieve in reality when the business requires you to be available all the time with no issues because that service that might be affected makes the company a million dollars a day. Why would the security community at all be advocating for increased attack surface? Access to shares, mapped drives, and NAS don't require domain admin for atatckers to smash and grab. Access to databases often leads to privilege escalation and ability to exfil from tier 2. If Tier 2 should be treated as hostile, why not remove it? Again, it's a documented best practice. I, like you, got domain admin on every engagement except one (because they didn't want me to). How often was I able to achieve that from a cloud only device? Just a couple times. It's significantly harder to compromise a global admin in that scenario unless you phish them directly or land on a device in a privileged role.

I agree! AD is insecure as hell.
I will extend this advice and say to move your employee endpoints out of AD and manage them in the cloud. There's no need for them to be hybrid joined anymore.

Let’s set the record straight: @lcfr_hax was the first to discover php2shell and develop a working exploit. See his August 5 tweet: xitter.cf/lcfr_hax/status/208503… His work convinced the PHP Foundation to invest in fixing this entire bug class. He then worked around the clock to review, test, and retest the patches.

Two critical vulnerabilities have been identified in PHP, a widely used programming language that powers websites and web applications. These vulnerabilities (CVE-2026-109618 and CVE-2026-109619) could allow malicious cyber actors to remotely execute code in PHP core, potentially compromising sensitive data and networks. The FBI urges organizations to take the following steps now: ➡️ If an immediate update is not feasible it is recommended that organizations take the system offline until it can be fully mitigated. ➡️ Immediately update affected PHP installations following the guidance on php.net. Inventory where PHP runs in your environment, prioritizing internet-facing systems and vendor products that bundle PHP. ➡️ Monitor web servers for suspicious activity, including PHP processes unexpectedly launching command shells or downloading files. Ensure appropriate process-monitoring capabilities are in place to help identify potential exploitation. ➡️ If you find signs of compromise, isolate affected systems, preserve your web server and PHP logs, and report it to your local FBI field office or ic3.gov. Those reports help us identify the actors involved and warn other organizations before they become victims. For the latest information, follow PHP’s announcement on php.net, CERT-EU Security Advisory 2026-018, and CISA’s Known Exploited Vulnerabilities catalog.

🚨 ConnectWise has suspended Cloud Backup and disabled 7 app identities after attackers compromised Microsoft 365 tenants. Backups and restores are unavailable. Previously issued access tokens may remain valid. Read: thehackernews.com/2026/10/co…

Microsoft Threat Intelligence is tracking an active supply chain attack in which a threat actor compromised the trusted OAuth App of the backup application ConnectWise Cloud Backup (AppId: 506e08f9-6e9a-4da4-942b-a099a03644ae), formerly SkyKick Backup, to obtain access tokens across customer tenants. ConnectWise Cloud Backup is a multitenant vendor application; customers grant consent for the application to operate in their tenants. We assess that the threat actor likely abused permissions previously granted by customers to the application, including highly elevated permissions like Directory.ReadWrite.All. On October 15, 2026, we observed broad successful service principal authentication originating from the IP address 144.172.64[.]128. Follow-on activity included Microsoft Graph API reconnaissance and attempts to add additional credentials on the related service principal in target tenants to maintain direct access as a backdoor. Microsoft Defender detects post-exploitation activity with the following alerts: - Any alert related to "Suspicious sign-in" - Graph API activity from a Microsoft threat intelligence IP address - Verified Threat Actor IP Defenders should review service principal sign-ins from unrecognized IP addresses, app credential changes, and OAuth grant activity associated with this specific OAuth AppId. In addition, we recommend looking for Threat Intelligence alerts on matching of IP against the Graph API activity and service principal activities. We will continue to monitor this incident and will share updates as they become available. We encourage customers to check ConnectWise advisory for more information and additional guidance: msft.it/6013aQBvV. Indicators of compromise (IOCs): - App name: ConnectWise Cloud Backup - AppId: 506e08f9-6e9a-4da4-942b-a099a03644ae - Publisher name: SkyKick - Source IP: 144.172.64[.]128 - User agents: Python-urllib/3.12, python-requests/2.31, python-requests/2.34.2
