Detects the execution of suspected Sauron Loader components staged in C:\ProgramData\keyroll\ (rnpkeys.exe or tdwp.dll) followed by an outbound network connection from the same host within a 2-minute window. This behavior correlates the staging of malicious binaries with the loader's automated outbound registration attempt.

This rule monitors for indicators of compromise (IOCs) associated with the threat actor SideCopy and their associated malware, such as ReverseRAT. It hunts for specific malicious SHA256 file/process hashes, connections to known malicious C2 infrastructure (IPs and domains), requests to known malicious URLs, and user interaction with these URLs via email clicks.

Detects instances where package management tools (pip, npm, docker) spawn child processes that immediately attempt to read sensitive files (SSH keys, cloud/container credentials) or perform outbound network connections. This behavior is indicative of a trojanized supply-chain package executing malicious post-install logic to exfiltrate secrets or establish initial communication with a C2 server.

This rule detects Terraform CLI execution of the 'init' command correlated with network access to HashiCorp AWS registry domains, or the presence of Terraform lock files in specific sensitive or project-related directory paths. This combination often indicates infrastructure-as-code management activities or potential misuse of Terraform in a production environment.

This rule performs a retrospective hunt for indicators of compromise (IOCs) associated with the ClosedQuorum malware. It identifies suspicious activity by matching against known file hashes, specific filenames, and network traffic directed towards services (such as DeepSeek, OpenRouter, Mistral, and Discord) which the malware uses for C2 or data exfiltration. The detection logic aggregates results from file system, process, and network telemetry.

Detects network activity associated with the 'ClickFix' social engineering campaign, which commonly targets users with fake error messages to trick them into executing malicious commands. The rule identifies communication with known malicious infrastructure (domains and IP addresses) found in CommonSecurityLog events, while implementing filters to exclude common security scanners and deduplicating per-host alerts.

Detects the use of common scripting and command-line utilities (such as curl, python, or bash) to interact with known Polygon blockchain RPC endpoints or specific smart contract addresses/selectors, which may indicate unauthorized interaction with decentralized applications or crypto-assets.

Detects outbound network traffic from internal hosts to known IP addresses associated with Exvicy Malware-as-a-Service (MaaS) Command and Control (C2) or hosting infrastructure. This rule acts as an indicator of compromise (IOC) match to identify potential infected hosts communicating with malicious external servers.

This rule detects network connections from internal devices to a list of known malicious domains and IP addresses. These indicators are commonly associated with command and control (C2) infrastructure or malicious activity, and alerting on these connections can help identify compromised systems within the environment.

Detects anomalous, chained execution patterns initiated by AI agents integrated with Model Context Protocol (MCP) servers. The rule identifies a multi-stage sequence involving the invocation of browser automation tools followed by shell execution and subsequent outbound network activity, potentially indicating an AI-driven attack chaining filesystem, shell, or cloud-API access in an unauthorized manner.
