This rule detects outgoing HTTP requests to 'apimantax.otax.fun' attempting to initiate a WebSocket upgrade connection. This is characteristic of the Mantax Otax v2 malware family establishing a Command and Control (C2) channel.
Detects HTTP POST requests to gapidriver.com/api/rest.php containing stager-specific status messages like 'build started', 'launch error', or 'all builds loaded', indicating NeedleStealer malware command-and-control activity.
Detects HTTP POST requests to gapidriver.com/api/rest.php containing stager-specific status messages like 'build started', 'launch error', or 'all builds loaded', indicating NeedleStealer malware command-and-control activity.
Detects Odyssey Stealer malware communicating with a known C2 infrastructure using TLS and performing data exfiltration via HTTP requests to raw-IP destinations using disguised file names such as analytics.gif, pixel.png, and content.js.
Detects repeated manual HTTP GET requests from many distinct source IPs to a canary token resource. The URI pattern follows a format indicative of a tracked canary token resource, and the threshold of 49 unique source IPs accessing the resource within a prolonged period suggests potential unauthorized reconnaissance or probing activities.
Detects high-frequency, repeated access to a specific fraud-tracking or canary token link by sources utilizing rotating VPNs or proxies over an extended period. This behavior is indicative of automated probing or credential validation attempts associated with the Phantom Deal campaign.
Detects a specific adversary pattern termed 'Phantom Deal' where a user is socially engineered into disabling their VPN (by claiming a link won't open), followed immediately by a rapid succession of accesses to the same tracking or canary link from that user account. The rule correlates sign-in events indicating a shift in VPN or MFA context with subsequent bursts of URL clicks.

Detects high-frequency, repeated access to a specific fraud-tracking or canary token link by sources utilizing rotating VPNs or proxies over an extended period. This behavior is indicative of automated probing or credential validation attempts associated with the Phantom Deal campaign.
Detects an attempt to exploit CVE-2026-24858 in FortiCloud SSO by sending a crafted SAML authentication request that lacks a signature. This vulnerability allows an attacker to bypass authentication by providing an unsigned SAML response.
Detects network requests to Google Sheets API containing specific markers (-tk- or val-) in the request body, indicative of potential command and control (C2) communication patterns often associated with malware payloads using Google Sheets for data exfiltration or command retrieval.
Detects anomalous URL-encoding patterns in requests handled by the Caddy web server. The rule uses regex to identify potentially malicious representations of path traversal characters and separators, such as double encoding or unusual Unicode mappings, which are frequently leveraged to bypass Web Application Firewalls (WAF) or path-based security filters.
Detects potential web reconnaissance or scanning activity against Microsoft IIS servers. The rule identifies suspicious behavior by monitoring for high frequencies of distinct URI requests, excessive 404 Not Found status codes indicative of path brute-forcing, and the presence of known security scanning user-agents.
Detects the creation of a WordPress administrator account within one hour of a recorded web request to a known web shell path (Mushr00w) or suspect plugin upload directory. This correlation is a high-fidelity indicator of post-exploitation persistence and administrative account hijacking.
Detects network activity communicating with Google Drive domains (drive.google.com and www.googleapis.com). This rule monitors outbound traffic, which may indicate the use of Google Drive as a command-and-control (C2) channel or for unauthorized data exfiltration.
This rule detects potential unauthenticated access or unauthorized configuration modifications to an AI agent management backend. It monitors HTTP logs for requests targeting configuration endpoints that lack proper authentication, specifically identifying attempts to retrieve sensitive information like Dify or Coze keys, or attempts to inject new agent configurations via unauthenticated POST requests.
Detects outbound web requests directed at public NPM mirrors and CDNs (unpkg, npmmirror, yarnpkg, jsdelivr) that contain strings matching known malicious package names associated with the 'Beamglea/ClickFix' campaign. This activity is typically indicative of a victim visiting a deceptive Cloudflare CAPTCHA phishing page designed to execute malicious scripts in the browser.
Detects potential Server-Side Request Forgery (SSRF) attacks targeting Grafana instances. The rule identifies suspicious 'grafana_api_request' calls that occur shortly after an unauthenticated discovery call ('tools/call') within the same session, where the target URL in the request header is not included in a defined allowlist of known internal Grafana hosts.

Detects high-frequency, automated requests to product and catalog pages within a short time window, characteristic of web scraping or catalog harvesting often used to feed fake-shop networks or build clone sites.
