Hunts for sqlservr.exe spawning command shells or system utilities, a pattern consistent with xp_cmdshell abuse. It also flags later steps from a public intrusion write-up: certutil decoding, SAM, SYSTEM or SECURITY hive saves and local account or group changes.
Results are grouped per device and day and ranked by stage count. Rows can also appear without a SQL parent when two later stages occur on the same device and day.
Triage: Some jobs use xp_cmdshell legitimately. Review the command line and the account. Hunting query, not an alert.
Limitations: Activity inside the SQL process with no child process is not visible. Renamed tools, obfuscation and privilege escalation tools are not covered. Needs Defender for Endpoint on the SQL servers.

Lists accounts that still sign in successfully with Authenticated SMTP over the last 30 days. Microsoft plans to disable Basic auth for SMTP AUTH by default for existing tenants at the end of December 2026.
Rows come from SigninLogs and AADNonInteractiveUserSignInLogs, grouped per account with source IP count, apps and first and last seen.
Triage: Find the owner of each account, then move the sender to OAuth or a mail relay before the change. Inventory query, not an alert.
Limitations: Covers only sign-ins that reach the logs. Cross check with the Exchange admin center SMTP AUTH Clients Submission Report, which keeps 90 days.

Tested in a live Sentinel tenant with a test file. Copilot Cowork and Claude Code folder conventions not validated with live events; the Tool column is a label only and does not filter results. Matches files named SKILL.md in OneDrive and SharePoint only; local-only files and marketplace plugin skills are not visible.

Detects the usage of command-line flags in AI coding assistant CLIs (such as Claude Code, Amazon Q CLI, and others) that intentionally skip security permissions, bypass approvals, or disable sandbox protections. The rule identifies potential developer activity that may inadvertently reduce the security posture of the development environment.

This rule monitors for the addition of new credentials (secrets) to service principals or applications in an Azure/Entra ID environment. It then correlates this event with subsequent mailbox activity (such as accessing mail items, sending mail, or message binding) performed by the application within 7 days of the credential creation. This detection pattern is indicative of potential OAuth application-based persistence and mailbox data exfiltration.
This rule monitors Entra ID Sign-in logs for authentication events flagged by risk detections related to anonymizing infrastructure, such as VPNs, TOR exit nodes, or proxies. It identifies successful logins and aggregate sign-in volume from these IP addresses, flagging successful logins as critical due to the potential for valid account abuse through multi-hop proxy chains.
