Detects network connections to known JeetBot infrastructure domains and IP addresses. The rule specifically identifies potential exfiltration of Twitch OAuth tokens via URL parameters or interaction with known token-collection proxy endpoints, which are associated with the JeetBot/Twitch Enhanced Viewer credential harvesting campaign.
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 network connections to JeetBot/Twitch Enhanced Viewer malicious browser extension infrastructure exfiltrating Twitch OAuth tokens. Apex domains (jeetbot.cc, api.jeetbot.cc) are gated on a token-forwarding indicator to avoid false positives.
Detects the installation or update of browser extensions that utilize 'declarativeNetRequest' or 'webRequest' APIs in conjunction with 'content_scripts' and either broad URL access ('all_urls') or access to sensitive web domains (e.g., Google Gemini, Microsoft Copilot, Perplexity, Claude). This combination is highly indicative of extensions designed for data interception, credential theft, or unauthorized web traffic manipulation.
Detects instances where the Chrome browser process accesses camera or microphone hardware, or invokes media device APIs, potentially indicating unauthorized audio or video recording.
Detects browser-based processes (Chrome, Opera, Edge) making network requests to AI and cloud service domains (Google Gemini, Claude, Opera). This rule monitors for potentially unauthorized or excessive browser communication with these services.
Detects the creation of compressed archive files (zip, rar, 7z, dat) followed by a significant network upload (exceeding 5MB) on the same host within a 30-minute window, which is indicative of staging and exfiltrating collected data.
Detects potential exploitation of CVE-2025-3248 in Langflow by identifying suspicious inbound network traffic targeting the /api/v1/validate/code endpoint, correlated with subsequent python child processes containing base64 decoding and execution primitives such as eval, exec, or subprocess.
Detects lateral movement activity where a host identified as running the Langflow framework attempts to connect to internal MySQL (3306) or Nacos (8848) services while utilizing root credentials, potentially indicating an attacker pivoting from a compromised application server.

Detects embedded CVE-2026-46300 (Fragnesia) Linux privilege escalation exploit code used by KATARU IoT malware, copied unmodified from public PoC
Detects the execution of the 'su' binary preceded by command-line strings that are highly indicative of known Linux privilege escalation exploits, specifically those targeting vulnerabilities like PwnKit (CVE-2021-4034). The rule monitors for common exploit payloads or status messages (e.g., 'prctl PR_SET_DUMPABLE', 'fork userns mapper') associated with successful exploitation attempts that manipulate environment variables or process attributes to elevate privileges to root, while filtering out legitimate container-related processes.

Detects KATARU IoT malware samples embedding the DirtyFrag (CVE-2026-43284) Linux local privilege escalation exploit copied from public PoC code, as part of a chained LPE attempt targeting root shell spawning
Detects KATARU IoT malware embedded exploit code for CVE-2026-31431 (Copy Fail) Linux privilege escalation, identified by shared exploit-chain strings and syscall sequences used to spawn su as root

This rule monitors network connection logs, DNS query logs, and common security logs for known indicators of compromise, specifically IP addresses and domains associated with command and control (C2) infrastructure.
Detects an attempt to exploit CVE-2026-42018 in JFrog Artifactory, where an attacker bypasses authentication checks for the AWS token endpoint using a trailing-slash URL manipulation technique. This rule monitors for POST requests to the '/access/api/v1/aws/token/' endpoint.
Detects attempts to bypass AWS IMDSv2 security protections via the LiteLLM /config/pass_through_endpoint, where attackers inject the 'x-pass-X-aws-ec2-metadata-token' header to potentially strip authentication requirements.
