Detects HTTP POST requests to a Gitea repository's diffpatch API endpoint whose body contains both a real git diff header and the malicious 'hooks/post-index-change' file path used by the CVE-2026-60004 exploit chain to plant an executable Git hook via an add/add merge collision.

Detects an attempt to exploit CVE-2021-33045 in Dahua devices, where an attacker sends a malicious JSON-RPC request to bypass authentication by leveraging the 'Loopback' login type and targeting the '127.0.0.1' address in the 'ipAddr' parameter.
Detects an attempt to exploit CVE-2021-33045 in Dahua devices, where an attacker sends a malicious JSON-RPC request to bypass authentication by leveraging the 'Loopback' login type and targeting the '127.0.0.1' address in the 'ipAddr' parameter.
Detects unauthorized exfiltration of sensitive information, such as camera credentials or location data, directed to the Telegram Bot API as part of the 'Operation CameraSwarm' campaign.
This rule detects attempts to exploit CVE-2021-33044, a vulnerability in Dahua hardware that allows an attacker to bypass authentication by sending a specially crafted request to the global.login endpoint.

Detects TLS connections using suspicious certificates identified as belonging to the SilkParasite threat actor. The rule monitors for specific certificate issuer strings paired with either malicious subject domain patterns (targeting Central Asian entities) or specific JA4X fingerprints associated with known malicious activity.

This rule monitors for network traffic related to known fake GitHub pages and malicious loader sites impersonating LastPass Authenticator. It detects attempts to access specific malicious domains and organization pages on GitHub, as well as the delivery of malicious pages containing spoofed trust badges and branding, commonly used in phishing campaigns.
Detects outbound network traffic to a known malicious IP address associated with Rapuncel Stealer, specifically looking for HTTP POST requests to the /upload endpoint, indicating possible data exfiltration.
Detects network activity associated with the EtherHiding technique, where adversaries leverage the Polygon blockchain to resolve command-and-control (C2) infrastructure and communicate with malicious smart contracts. This rule identifies specific JSON-RPC requests ('eth_call') using SloppyRAT contract selectors and DNS queries for blockchain-related RPC endpoints.
Detection of network traffic associated with the delivery of the Rapuncel information stealer. The rules monitor for large ZIP archives masquerading as LastPass Authenticator installers and detect attempts to reach out to external domains for DLL sideloading artifacts (TitanStorage.dll and ProManager.dll).
Detects potential unauthenticated Remote Code Execution (RCE) exploitation attempts targeting the IKEv2/ISAKMP VPN service on WatchGuard Firebox devices (CVE-2025-14733). The rule monitors UDP traffic on standard IKE ports 500 and 4500, looking for specific payload patterns and elevated data sizes consistent with exploitation attempts, coupled with a threshold to reduce noise.
This rule detects IDS/IPS or vulnerability management alerts triggered by exploitation attempts targeting the Cisco IOS XR control plane, specifically related to CVE-2026-20212.
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 network activity and email headers associated with the DoppelBrand campaign. The rule monitors DNS queries for specific IOC domains (service-nowinc.com, domainlify.net) and inspects SMTP traffic for malicious MAIL FROM addresses and Reply-To headers targeting these domains.
Detects high-frequency POST requests to the JFrog Artifactory '/access/api/v1/tokens' endpoint, which is indicative of mass exploitation attempts targeting vulnerabilities (CVE-2026-82329) against administrative token management.
This rule detects SQL injection attempts targeting the BuddyBoss members REST endpoint, specifically identifying exploitation patterns associated with the 'sqlmap' tool. The rule monitors for specific URL parameters including 'member_type', 'search_terms', and 'scope' in combination with an 'sqlmap' user-agent, indicating an automated exploitation attempt against the application.
Detects outbound network traffic consistent with the Chisel proxy/tunneling tool establishing a connection to an external VPS associated with the Miku threat actor. The rule monitors for established TCP connections to a specific remote IP address on port 443, utilizing a threshold to reduce noise by ensuring multiple connection attempts occur.
