Detects potential exploitation of CVE-2026-87886 in the Acronis Backup plugin for cPanel & WHM, where an adversary uses insecure file permissions to elevate privileges. The rule monitors for execution of file permission or ownership changing utilities (chmod, chown) targeting files associated with backup plugins.
Detects a suspicious scenario where a non-root process associated with Acronis backup plugins (typically used on cPanel, WHM, or Plesk servers) spawns a child process that executes with root privileges. This behavior is indicative of potential privilege escalation exploiting CVE-2026-87886.
Detects the use of chmod or chown commands to modify permissions or ownership of files associated with Acronis backup plugins within cPanel, WHM, or Plesk environments. This activity is indicative of potential unauthorized manipulation or exploitation of the backup configuration, such as that associated with CVE-2026-87886.
Detects Python scripts containing natural-language comments that narrate attack rationale, reasoning, or step-by-step intent. This behavior is a diagnostic signature of scripts generated or operated by AI agents, which tend to document their own processes in plain text comments, unlike human-written malicious code.
Detects potential database ransomware activity by correlating the usage of AES_ENCRYPT for record modification, followed by the dropping of tables and the insertion of ransom notes containing specific contact keywords (e.g., bitcoin, proton mail) within database queries or system logs.
Detects an attempt to exploit CVE-2025-3248, an unauthenticated remote code execution vulnerability in Langflow. The rule identifies POST requests to the '/api/v1/validate/code' endpoint that contain base64 encoded strings in the request body, which are characteristic of malicious Python payloads designed to execute arbitrary code.
This rule aggregates vulnerability data from Microsoft Defender for Endpoint (Threat and Vulnerability Management) over the last 7 days. It groups vulnerable devices by CVE ID and severity level, providing an overview of known software weaknesses currently present across the fleet.
This rule detects the use of 'npm' or 'node' to install packages from a registry other than trusted, standard registries (e.g., npmjs.org, GitHub). It specifically monitors command lines involving 'claude-code' that utilize custom, non-standard registry URLs. This behavior is indicative of potential supply chain attacks or the installation of unauthorized/malicious dependencies.
Detects shell/install scripts that deploy an XMRig-based Monero cryptominer, consistent with the install script planted on the LeakySensey git repository server

This rule detects the execution of processes associated with CLI proxy routers (such as CLIProxyAPI or router-for-me) that establish network connections to multiple AI provider APIs (e.g., Anthropic, OpenAI, Google Gemini) within a short window. This pattern is indicative of efforts to bypass rate-limiting or allowlisting mechanisms commonly used by corporate environments to control and audit AI service interactions.

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.

Detects attempts to delete, truncate, or overwrite critical system logs and user command history files (such as /var/log/auth.log, syslog, or .bash_history) on Linux systems using common utilities like rm, shred, and truncate. The rule includes exclusions for legitimate system maintenance processes like logrotate and cron.
This rule detects potentially unauthorized root account activity by monitoring for 'root' logon events and privileged process execution (such as 'su' or 'sudo'). It flags sessions or commands that occur outside of defined business hours, originate from unapproved IP addresses, use unapproved accounts, or are executed via suspicious parent processes, providing a high-confidence indicator of anomalous administrative behavior.
Identifies instances of Google Chrome running on endpoints with version numbers below the threshold patched for CVE-2026-85046. This detection focuses on specific build numbers (e.g., 152.0.7977.82 for Windows/Linux) to identify potentially vulnerable browser installations in the environment.
Detects network connections to command-and-control infrastructure associated with the JeetBot/Twitch Enhanced Viewer malicious browser extension. The rule triggers on connections to known malicious domains or IPs, as well as specific API endpoints on ambiguous domains that are used for exfiltrating Twitch OAuth tokens.

Detects file artifacts referencing OtterCandy malware, which combines OtterCookie and RATatouille RAT capabilities, associated with WaterPlum/Contagious Interview campaign
