Detects specific malformed HTTP request patterns associated with the Casbaneiro (Metamorfo) banking trojan. The rules identify suspicious beaconing attempts, including specific URI structures ('/$p', '/$or?u=') and malformed headers (missing Host header combined with specific Content-Length anomalies).
Detects unauthenticated requests to the WordPress admin-ajax.php endpoint utilizing the 'super_create_nonce' action. This action allows an unauthenticated user to generate a valid session nonce, which is a critical bypass mechanism often required for the exploitation of vulnerabilities within the Super Forms plugin, such as CVE-2026-14894.
KQL Query from file: repeated-unauthenticated-post-to-elementor-pro-forms-endpoint-cve-2026-32475-pr.kql
This rule detects network communication (via DNS queries, web logs, or device network events) with a list of known malicious domains associated with Command and Control (C2) activity.
Detects unauthenticated requests to the WordPress admin-ajax.php endpoint utilizing the 'super_create_nonce' action. This action allows an unauthenticated user to generate a valid session nonce, which is a critical bypass mechanism often required for the exploitation of vulnerabilities within the Super Forms plugin, such as CVE-2026-14894.
Detects anomalous credential retrieval activity occurring within 30 minutes of a GitLab Duo Chat GraphQL subscription request. This pattern is indicative of potential exploitation of CVE-2026-87719, which involves insecure deserialization within the GitLab EE GraphQL subscription serializer to facilitate unauthorized credential access.
This rule detects HTTP requests directed at suspicious URI patterns associated with 'LeakySensey' logs. It specifically monitors for attempts to access transaction or compromise log endpoints, which could indicate an attacker attempting to enumerate leaked data or verify compromised credentials from an exposed log repository.
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 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 originating from browser processes to known JeetBot command and control (C2) infrastructure. The rule identifies suspicious C2 communication and, specifically, attempts at token exfiltration by monitoring for auth tokens in the URL of requests directed to known JeetBot hosts and Twitch-related infrastructure.
Detects network connections originating from browser processes to known JeetBot command and control (C2) infrastructure. The rule identifies suspicious C2 communication and, specifically, attempts at token exfiltration by monitoring for auth tokens in the URL of requests directed to known JeetBot hosts and Twitch-related infrastructure.
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 HTTP traffic from internal hosts to the 'gapidriver.com' domain, specifically identifying the GapiUpdate stager behavior. The rule looks for authenticated GET requests to '/api/get.php' using a specific Bearer token and User-Agent, as well as status reporting to '/api/rest.php'.
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 DNS queries, TLS SNI headers, and HTTP host headers associated with identified C2 infrastructure for NetSupport Manager malware, specifically domains themed around 'GTA6'. These indicators are used by attackers for command and control communication.
Detects HTTP requests attempting to access 'cmd.jar' on Cisco Firepower Management Center (FMC) devices, which is indicative of post-exploitation activity related to CVE-2026-20079, where an attacker may be attempting to retrieve or upload a command executor.
Detects an attempt to exploit CVE-2026-20079 in Cisco Firepower Management Center (FMC) by targeting the home.jsp file with a specific malicious parameter string indicating post-exploitation activity.
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 outbound WebSocket upgrade requests from internal network assets to known IronToll C2 IP addresses, restricted to requests whose Host header ends in one of the disposable TLDs observed across the campaign's 73+ rotating lookalike domains (.cfd, .sbs, .shop, .icu, .buzz, etc). This narrows the alert to the campaign's actual phishing-domain pattern rather than any WebSocket traffic that happens to reach the same shared Tencent/Alibaba cloud IPs, and a per-source threshold caps repeat alerts from the same host to one per hour.
Detects DNS queries, TLS SNI, and HTTP Host header traffic associated with the IronToll phishing campaign. The rule specifically monitors for government-impersonating domains and lookalike domains utilizing various non-standard top-level domains (TLDs).
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.
