Detects anomalous MS_T120 channel binding and MCS handshake patterns characteristic of the BlueKeep (CVE-2019-0708) remote code execution vulnerability in Microsoft RDP services.
Detection rules identifying malformed RDP MCS Connect Initial PDUs and unusual service crashes following RDP connection attempts, both indicative of exploitation attempts against the CVE-2019-0708 (BlueKeep) vulnerability.
Detects unauthorized or suspicious POST requests to the Cisco Firepower Management Center (FMC) web interface that lack standard authentication headers (Cookie, Authorization, or X-Api-Token). This pattern is consistent with exploit attempts targeting CVE-2026-20079.
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.
Detects attempts to exploit a vulnerability in WSO2 API Manager and Traffic Manager that allows for authentication bypass by utilizing a malformed JWT with the 'alg=none' header. Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.
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.
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.
Detects repeated authentication attempts over PPTP (port 1723) or L2TP (port 1701) protocols originating from an external network, indicative of potential brute-force activity against remote access services.

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 Server-Side Request Forgery (SSRF) attempts originating from the Grafana MCP (Model Context Protocol) process. The rule specifically monitors for instances where the 'grafana_api_request' tool is used in conjunction with a 'X-Grafana-URL' header targeting cloud metadata IP ranges (169.254.0.0/16), or where the host attempts to resolve GCP metadata domains ('metadata.google.internal'). This behavior is indicative of an attacker attempting to access cloud provider instance metadata to exfiltrate security credentials.
Detects HTTP requests containing JNDI lookup patterns commonly associated with the Log4Shell (CVE-2021-44228) vulnerability exploitation, where an attacker attempts to force an application to execute remote code via Java Naming and Directory Interface (JNDI) injection.
This rule detects attempts to exploit a path traversal vulnerability (CVE-2024-21762) in FortiOS SSL-VPN by monitoring for malformed GET requests targeting the /remote/fgt_lang endpoint. The rule also tracks successful exploitation by identifying HTTP 200 responses containing Linux password file patterns (root:x:0:0:), indicating potential remote file disclosure.

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.
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 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 HTTP POST requests targeting Cisco Firepower Management Center (FMC) that contain strings associated with internal service account processes or configuration files, indicative of an attempt to exploit CVE-2026-20316.
Detects unauthorized HTTP Basic authentication attempts targeting Cisco Firepower Management Center (FMC) using hardcoded service account credentials associated with CVE-2026-20316.
Detects unauthorized or suspicious POST requests to the Cisco Firepower Management Center (FMC) web interface that lack standard authentication headers (Cookie, Authorization, or X-Api-Token). This pattern is consistent with exploit attempts targeting CVE-2026-20079.
