Detects exploit attempts targeting the authentication bypass vulnerability in Dahua NetKeyboard devices (CVE-2021-33044) by monitoring HTTP requests containing malicious 'global.login' RPC parameters.
Detects unauthenticated HTTP POST requests targeting the FortiGate administrative API (/api/v2/), which may indicate exploitation attempts related to CVE-2025-25249. The rule specifically looks for requests lacking authentication headers (Cookie or Authorization).
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.
The following analytic detects Cisco IOS-XE configuration changes performed by the WebUI WSMA process.
Detects unauthenticated HTTP POST requests targeting the FortiGate administrative API (/api/v2/), which may indicate exploitation attempts related to CVE-2025-25249. The rule specifically looks for requests lacking authentication headers (Cookie or Authorization).
This rule detects potential exploitation attempts against SonicWall SMA1000 appliances, specifically targeting the /wsproxy endpoint using a custom 'SMA Connect Agent' user agent string. This behavior is associated with SSRF vulnerabilities (CVE-2026-15409 and CVE-2026-15410) identified as being utilized by the threat actor group UTA0533 in campaigns involving INC Ransomware.
This rule identifies instances of Cisco Secure Email Gateway (AsyncOS) running vulnerable versions that are susceptible to CVE-2026-76461. It parses the software inventory data to identify appliances within branches 15.5, 16.0, and 16.5, comparing the patch and build versions against the known secure release versions (15.5.5-0141, 16.0.4-302, 16.5.0-780).
Detects unauthenticated HTTP POST requests targeting the FortiGate administrative API (/api/v2/), which may indicate exploitation attempts related to CVE-2025-25249. The rule specifically looks for requests lacking authentication headers (Cookie or Authorization).
Detects the creation or use of known backdoor accounts ('p2pwn', 'p2password') on Dahua surveillance devices, which are often utilized by adversaries to maintain unauthorized access to compromised hardware.
This rule detects the creation or modification of specific files ('auth_codes.json' or files containing 'seria2') associated with the offline recovery process of Dahua devices. The presence of these files suggests an attempt to utilize or access deterministic recovery codes to bypass authentication on the device.
Detects anomalous, high-frequency, and highly regular HTTP requests directed at Dahua camera infrastructure for the purpose of harvesting snapshots. The rule uses statistical analysis to identify automated collection patterns, such as a high volume of requests across multiple devices with low variance in request intervals.
This rule detects suspicious UDP traffic directed at port 8800 targeting the Dahua P2P cloud relay interface. It specifically monitors for enumeration attempts against device serial numbers, which may be a precursor to unauthorized access or reconnaissance against vulnerable Dahua devices.
Detection rules identifying suspicious communication patterns associated with Dahua P2P Cloud Relay devices, including WSSE authentication attempts and device probing to known cloud relay endpoints. These patterns are consistent with reconnaissance and exploitation activity against IoT devices within the context of Operation CameraSwarm.
Detects network activity related to the exploitation of Dahua P2P relay services via easy4ipcloud.com. The rule monitors for unauthorized device probing, serial number enumeration, and illicit relay authentication attempts (e.g., using DHP2P protocols and X-WSSE authentication), which are indicative of attackers attempting to abuse IoT device remote access functionality (CVE-2025-31702).
Detects network activity related to Dahua P2P relay services (easy4ipcloud.com) on port 8800. The rules monitor for device lookup queries (/online/p2psrv/), probe requests (/probe/device/), and the presence of WSSE authentication headers, which may indicate interaction with or exploitation attempts by tools targeting P2P-enabled surveillance hardware.
This rule identifies instances of Cisco Secure Email Gateway (AsyncOS) running vulnerable versions that are susceptible to CVE-2026-76461. It parses the software inventory data to identify appliances within branches 15.5, 16.0, and 16.5, comparing the patch and build versions against the known secure release versions (15.5.5-0141, 16.0.4-302, 16.5.0-780).

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.
This rule detects anomalous high-frequency, short-duration bursts of CAPWAP (Control and Provisioning of Wireless Access Points) traffic originating from external sources and targeting internal FortiGate devices. This behavior is indicative of automated exploitation attempts, specifically targeting known heap-grooming activities used in vulnerabilities like CVE-2023-27997, which rely on repetitive 'Add-Station' operations. Legitimate controller traffic is filtered by focusing on internal-to-internal communication patterns.
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.
