Microsoft is moving to disable NTLM by default, with some exceptions.
If implemented, this will have a significant impact on threat actors abusing credentials within a network.
The move to IAKerb and local KDC for local and cached authentication will be....interesting.
Falling back to NTLM for authentication using IP addresses instead of FQDNs, I suspect, will keep NTLM in most environments, but overall this is a hopeful step in the right direction.

Defenders are structurally outpaced. Threat actors operate without vendor dependencies or infrastructure constraints.
The Agentic SecOps Workspace transforms a natural language request into production-ready detection coverage in minutes.
The AI interprets the threat requirement, generates detection logic, validates syntax, deploys to production, and tests against both positive and negative indicators.
This isn't a use case built into a chatbot. It's an AI operator with access to the same APIs and tools as your security engineers. You focus on outcomes, the AI figures out how to achieve them.

Threat actors continue to operationalize current-events lures as part of malware delivery chains.
Recent research shows a backdoor deployed via attachments themed around breaking geopolitical news, using legitimate binaries and DLL sideloading techniques for persistence.
No attribution assumptions - just a reminder that contextual relevance remains one of the most effective social engineering tools.
What controls have you found most effective against news-driven phishing?

• Deploy EDR/AV on endpoints.
• Enable IDS/IPS at network edge.
• Automatic vulnerability scans (schedule weekly/monthly).
• Monitor persistence techniques (cron, startup scripts).
• Block known malicious IP ranges & TLDs.⸻
🏢 9. Physical & Cloud Security
• Restrict physical access to server racks/rooms.
• Enable provider security tools (AWS Security Groups, Azure NSG, IAM).
• Harden cloud images (CIS benchmarks).
• Review cloud logging & audit trails regularly.
• Disable unused cloud API keys / roles.⸻
📜 10. Policy & Compliance
• Use CIS / NIST / ISO-27001 benchmarks.
• Track & document every access change.
• Force annual access reviews & key rotation.
• Perform regular security training for admins.

Server Security Checklist — Essential Hardening Guide
Securing your servers isn’t optional — it’s your first line of defense against data breaches, ransomware, insider threats, and lateral movement. Use this checklist as a baseline for Linux, Windows, cloud, hybrid, or on-prem servers.
⸻
🔧 1. System & OS Hardening
• Keep OS & packages updated (apply security patches frequently).
• Remove / disable unused services & software.
• Enforce secure boot + BIOS/UEFI passwords.
• Disable auto-login and guest accounts.
• Use minimal OS images only (reduce attack surface).⸻
🔐 2. Access Control
• Enforce strong passwords & MFA everywhere.
• Use RBAC & least privilege access.
• Disable root/Administrator login over SSH/RDP.
• Rotate credentials & keys regularly.
• Implement just-in-time access for privileged users.⸻
🌐 3. Network Security
• Restrict inbound/outbound traffic via firewalls.
• Segment critical servers from general LANs/VLANs.
• Disable unused ports & protocols.
• Enable DoS/DDoS protection.
• Apply zero-trust network principles.⸻
🔑 4. Secure Remote Access
• Use SSH key-based authentication (disable password login).
• Enforce VPN for admin access.
• Log & monitor all remote access sessions.
• Disable legacy protocols (Telnet, FTP, SMBv1).
• Require bastion/jump host for critical access.⸻
📊 5. Logging & Monitoring
• Enable centralized logging (syslog / SIEM).
• Track failed login attempts & anomalies.
• Configure alerts for privilege escalation or config changes.
• Monitor log tampering.
• Retain logs securely for audits & forensics.⸻
🔒 6. Data Protection
• Encrypt data at rest (LUKS, BitLocker, etc.).
• Encrypt data in transit (TLS 1.2+).
• Strict database access policies.
• Regular, offline, immutable backups.
• Test restore procedures (don’t assume backups work).⸻
🔁 7. Application & Patch Management
• Keep middleware, frameworks, and apps patched.
• Delete default credentials & sample files.
• Enable code signing for software packages.
• Use secure coding practices (OWASP Top 10).
• Implement dependency scanning (Snyk, Trivy, etc.).⸻
🛡️ 8. Malware & Intrusion Defense
• Deploy EDR/AV on endpoints.
• Enable IDS/IPS at network edge.
• Automatic vulnerability scans (schedule weekly/monthly).
• Monitor persistence techniques (cron, startup scripts).
• Block known malicious IP ranges & TLDs.⸻
🏢 9. Physical & Cloud Security
• Restrict physical access to server racks/rooms.
• Enable provider security tools (AWS Security Groups, Azure NSG, IAM).
• Harden cloud images (CIS benchmarks).
• Review cloud logging & audit trails regularly.
• Disable unused cloud API keys / roles.⸻
📜 10. Policy & Compliance

New blog post live for my Sentinel Saturday series! :1000: :apartyblobcat:
Read the blog 👉 https://marshsecurity.org/sentinel-saturday-using-tasks-with-automation/In this post, I explore the power of using Microsoft Sentinel Tasks as part of your automation workflows.
Most teams aren’t getting the full #value out of Tasks in Microsoft Sentinel. Are you? When you combine Sentinel Tasks with automation, they become a game-changer.
- Auto-create tasks when automation fails (so nothing slips through the cracks)
- Auto-complete tasks when automation succeeds
- Use tasks to verify automation outcomes
- Build engineering feedback loops and automation #QARead the blog 👉 https://marshsecurity.org/sentinel-saturday-using-tasks-with-automation/
