Detects activity associated with a potential RMM (Remote Monitoring and Management) agent communicating with known malicious infrastructure and accessing sensitive files like credentials or IDs. This often indicates an adversary leveraging legitimate RMM tooling for post-compromise activity or exfiltration.
Detects reconnaissance and lateral movement activity via kubectl. The rule monitors for the enumeration of Kubernetes secrets or configmaps, and the deployment or application of privileged workloads featuring flags such as hostPath mounts, privileged execution, hostNetwork, or hostPID.
Detects anomalous behavioral patterns where an AI agent process (e.g., Claude Code, Cursor, Aider) performs multi-category discovery of its own runtime environment, plugins, and host configuration. The rule identifies agents that trigger processes spanning at least three distinct discovery categories (Network, File/Plugin, Software, or System) within a short timeframe, indicating potential reconnaissance of agent-authorized capabilities and tools rather than standard host exploration. Covers T1082, T1518, T1083, T1016

Detects second-stage reconnaissance patterns indicative of the VelvetCake framework. The rule identifies PowerShell execution that combines multiple discovery commands (system information, network configuration, process listing, file system inspection, and antivirus/security software enumeration) within a single execution sequence or related process events.
Detects the 'comet.exe' process (Perplexity AI agent) performing file read, write, rename, or creation operations outside of standard browser paths (e.g., AppData, Temp, Downloads). This behavior potentially indicates the process is being leveraged for unauthorized data access or staging files on the local filesystem.
Detects unauthorized processes (non-browser) reading sensitive browser session and credential files (e.g., Cookies, Login Data) across multiple user profiles, followed by immediate outbound network connections. This behavior is highly characteristic of commodity information stealers (e.g., LummaC2, Stealc, Vidar) attempting to exfiltrate browser-stored credentials and session data.
Detects reconnaissance and lateral movement activity via kubectl. The rule monitors for the enumeration of Kubernetes secrets or configmaps, and the deployment or application of privileged workloads featuring flags such as hostPath mounts, privileged execution, hostNetwork, or hostPID.
Detects executable files launched from torrent-related directories or parent processes that perform reconnaissance commands or registry queries indicative of sandbox or virtualization detection, a technique observed in the MovieReaper malware loader.
Detects the execution of PowerShell commands that enumerate files within sensitive user directories such as Desktop, Downloads, Documents, or OneDrive, using common cmdlets like Get-ChildItem with recurrence or filtering. This behavior is indicative of an adversary attempting to discover or stage files for exfiltration.
Detects the execution of HTSPnew.Exe with specific command-line arguments indicative of KRSID ransomware operations, such as configuration flags for paths, batch processing, and dry-run modes. The use of these flags with this specific executable name is a strong indicator of malicious activity.
Detects the execution of PowerShell commands that enumerate files within sensitive user directories such as Desktop, Downloads, Documents, or OneDrive, using common cmdlets like Get-ChildItem with recurrence or filtering. This behavior is indicative of an adversary attempting to discover or stage files for exfiltration.
Detects the use of PowerShell to enumerate storage devices (USB, disk, partition information) and perform file operations such as copying or logging, potentially indicating malicious data collection from removable media or external drives.
Detects file creation events involving the 'SmartUploader' configuration file or process execution events referencing the tool, which may indicate unauthorized data collection or staging activity.
Detects high-volume file/directory enumeration behavior by the PlugX side-loaded process GRrte.exe, consistent with PlugX's use of FindFirstFileW/FindNextFileW/FindFirstFileExW for file and directory discovery (T1083).
Detects a sequence of PowerShell commands consistent with the VelvetCake reconnaissance module, including enumeration of antivirus software via SecurityCenter2, system information, IP configurations, running processes, recent files, and drive mapping within a short timeframe.
Detects Git command line executions involving 'branch', 'checkout', or 'push' operations that reference what appear to be full commit hashes as branch references. The rule flags instances where 'refname is ambiguous' warnings are generated, which may indicate an attempt to manipulate or interact with git repositories in ways that conflict with existing branches, potentially suggesting malicious repository tampering or discovery activity.
Detects high-volume filesystem activity (exceeding 300 operations in 5 minutes) initiated by 'claude-code' or 'claude' processes. This behavior may indicate an autonomous, patched, or jailbroken AI coding assistant performing mass file operations or reconnaissance without user confirmation.
This rule monitors process creation, file system activity, and HTTP logs for indicators associated with the 'GHOST-VAULT' or 'GHOST-CRED' threat activity. It specifically triggers on files or paths containing 'GHOST-VAULT-', processes named 'ghost_' or containing 'ghost_' in the command line, and HTTP requests containing 'GHOST-CRED/3.0', 'GHOST-VAULT/', or 'GHOST/0day'.
