Detects attempts to list, read, create, update, or delete Kubernetes secrets via the Kubernetes API server. This activity can indicate an adversary attempting to gain access to sensitive information or manipulate the environment.
Detects rapid high-volume file and messaging operations across multiple Microsoft 365 services (SharePoint, OneDrive, Teams, Exchange) within a compressed 10-minute window from a single identity and IP address. This behavior can indicate data exfiltration or reconnaissance by an adversary.
Slack Anomalous Activity Detected
Cortex XDR
This rule detects anomalous activity reported by Slack's internal anomaly detection system. This includes events such as impossible travel, new device access, suspicious IP changes, and other behavioral anomalies that could indicate a compromised account or unauthorized access to a Slack workspace.

Detects the creation or modification of suspicious Launch Agent or Launch Daemon .plist files, or a hidden application support directory, masquerading as 'com.apple.accountsd' on macOS. This behavior is often indicative of persistence mechanisms used by adversaries.
Detects web access logs matching the specific 'wp_debug_session' parameter used by the ErrTraffic webshell to communicate with compromised servers. This rule identifies HTTP requests containing both 'wp_debug_session=' and 'mode=php' in the URI query string, which are indicators of ErrTraffic webshell activity.
Detects network traffic associated with the EvilTokens phishing kit's 'killed' gate check mechanism. The kit GETs /api/device/gate/<PAGE_ID> with the ngrok-skip-browser-warning header. When the backend returns a killed flag, the phishing page wipes the DOM and renders a fake 'Page Not Found - Microsoft' error to evade analysis or block specific victims.
Detects PowerShell execution patterns used for host reconnaissance and application enumeration, specifically looking for combinations of Get-StartApps and Get-AppxPackage with silent error handling. This behavior was observed in the easy-day-js malware dropped via the Mastra npm supply chain compromise.
This rule detects network connections initiated by scripting engines (wscript.exe, cscript.exe) or PowerShell (powershell.exe) to common Remote Desktop Protocol (RDP) ports (3389, 3390, 3391). This activity can be indicative of an adversary attempting to establish or pivot RDP sessions using unexpected processes, potentially for lateral movement or persistence.
Detects network connections on port 21 (FTP) where the RemoteUrl contains common FTP data type commands ('TYPE A', 'TYPE I', 'TYPE a', 'TYPE i'). This could indicate active FTP sessions, potentially for data transfer or exfiltration.
