Detects Node.js processes executing suspicious command lines that involve fetching and executing remote JavaScript code. This behavior is indicative of a loader or downloader script commonly used to pull and evaluate malicious payloads at runtime, specifically referencing indicators associated with 'GHAPPIER'.

Detects potential path traversal or unauthorized access attempts by Semantic Kernel Agents (or related processes like Python/DotNet) to sensitive host files. The rule monitors for file read, creation, or modification activities targeting sensitive credentials, configuration files (e.g., .ssh, .aws, .kube), and system files, which could indicate a sandbox escape or malicious data collection.

Detects exploit attempts targeting a Python prompt-injection vulnerability (CVE-2026-26030). The rule identifies command lines attempting to traverse Python's object hierarchy (e.g., using __class__, __base__, __subclasses__) to import the os module and execute system commands. It also flags subsequent child processes (e.g., calc.exe, cmd.exe) spawned by Python interpreters or Semantic Kernel host processes.

Detects the invocation of file-related functions (DownloadFileAsync, upload_file) within the Semantic Kernel framework that lack associated validation function calls. This pattern is indicative of potential Remote Code Execution (RCE) or unauthorized file system access scenarios where an LLM agent is coerced into performing dangerous file operations without path sanitization.

Detects the execution and behavioral patterns associated with the malicious 'indexed-btree' npm package. The rule specifically looks for code patterns where a malicious loader is injected into 'BTree.prototype.set' and triggered at runtime. It also monitors for suspicious process spawning behavior, such as running node processes with detached and hidden windows flags, often used by the package to maintain persistence or execute malicious payloads silently.

Detects the use of common command-line tools (curl, wget, python, etc.) to interact with known cloud provider metadata service IP addresses or URL paths, often performed by shell processes. This behavior is frequently associated with initial reconnaissance or attempts to steal identity tokens from cloud-based virtual machines.

This rule detects potentially malicious activity involving Node.js modules. It monitors for the deletion of specific 'sharedLoad.min.js' or 'extended' files within 'node_modules' directories, the execution of Node.js processes attempting file deletion operations (like 'unlink' or 'rm') within 'node_modules', and the creation or modification of JavaScript files within 'node_modules' that contain 'btree' references. This activity may indicate an attempt to tamper with application dependencies, inject malicious code, or remove artifacts.

Detects execution of Node.js processes loading specifically named JavaScript files ('sharedLoad.min.js') within the 'node_modules/indexed-btree' directory, or file modifications involving these specific paths, which may indicate a malicious loader or supply chain compromise attempt.

004
This rule detects instances where a Node.js process spawns a child process, also running as node.exe, that attempts to execute a specific JavaScript file path (sharedLoad.min.js or its extended version). This behavior is characteristic of certain Node.js-based applications or potentially malicious scripts using shared loaders for modular execution.

This rule detects the execution or presence of specific Go or Terraform modules known to be malicious or associated with suspicious dependency retrieval. It monitors command-line activity from terraform.exe/go.exe attempting to download/run from these paths, as well as file system events involving these specific folder paths and filenames.

This rule detects potential exploitation attempts targeting vulnerabilities within the libheif image processing library. It monitors for image processing binaries (e.g., convert, magick) executing with command-line arguments related to HEIF/HEIC files, followed by multiple application crash events (SIGSEGV, coredumps) associated with libheif on the same device within a short time window.

Detects the creation or writing of the specific log file '/logs/send_sms_apix.log' associated with the AnonyMousKIT Phishing-as-a-Service (PhaaS) platform. This file is typically used by the kit to record SMS billing or gateway activity during a phishing operation.

Detects HTML smuggling files identified as 'FlipBook' lures, commonly used in device-code phishing campaigns. These lures utilize client-side JavaScript for AES-GCM decryption, extensive comment-based obfuscation, and specific junk-padding techniques to bypass security controls and trick users into providing credentials.

Detects a suspicious sequence of user activity where a device visits a social media platform (Twitter/X) followed shortly by navigation to a Google Doc. This pattern is often consistent with phishing lures where victims are enticed via direct messages or social engineering to open a malicious document hosted on Google Docs.

Detects a suspicious pattern where a user browser visits a Google Document and subsequently initiates a connection to the Telegram Bot API within a short timeframe (10 minutes). This sequence is indicative of malicious Google Apps Scripts embedded in documents attempting to exfiltrate victim information (IP, geolocation, device details) as part of a reconnaissance phase before a ClickFix-style payload delivery.

Detects a Redis process connecting to a suspected rogue replication master (using non-standard ports or known malicious IPs) followed by a file modification to a system cron directory. This sequence is indicative of a Redis Rogue Replication exploit where a crafted RDB file is used to achieve persistence by writing a malicious entry to a cron job.
