Detects attempts to exploit CVE-2021-33044, an authentication bypass vulnerability in Dahua NetKeyboard hardware. The rule triggers when a POST request containing 'global.login', 'clientType: NetKeyboard', and 'loginType: Direct' is observed, which allows unauthorized access by manipulating authentication parameters.
Detects network traffic attempting to exploit the Dahua CVE-2021-33044 vulnerability, which allows an unauthenticated user to bypass authentication mechanisms on affected NetKeyboard devices.
Detects attempts to exploit a buffer overflow vulnerability (CVE-2026-7273) in Zyxel GS1900 series switches. The rule monitors for oversized POST requests directed at CGI scripts on the device's web management interface.
Detects malicious interactions with an unauthenticated Docker daemon API, specifically identifying the creation of privileged containers with host bind mounts, the deployment of containers with specific naming conventions for network reconnaissance (netns-probe/net-setup), subsequent container start events, and the use of the Docker exec API to perform host namespace escapes via nsenter.
Detects attempts to exploit CVE-2021-33045, an authentication bypass vulnerability in certain Dahua camera firmware. The attack involves sending a crafted login request containing 'global.login', 'clientType', and 'Loopback' parameters, which allows an attacker to bypass authentication mechanisms.
This rule detects attempts to exploit CVE-2021-33044 in Dahua devices, specifically targeting the NetKeyboard clientType during the global.login RPC request. This vulnerability allows an unauthenticated remote attacker to bypass authentication mechanisms.
This rule detects attempts to exploit the authentication bypass vulnerability in Dahua firmware (CVE-2021-33045) via the JSON-RPC interface. The attacker attempts to manipulate the 'loginType' and 'ipAddr' fields, specifically using 'Loopback' as the login type and '127.0.0.1' as the IP address to bypass security controls.
Detects an unauthenticated remote code execution (RCE) attempt against Langflow via the /api/v1/validate/code endpoint. The rule monitors for POST requests containing code execution patterns such as eval, exec, os.system, or subprocess, indicating an attacker attempting to leverage the vulnerability to execute arbitrary commands.
Detects HTTP requests targeting the /terminal/ws endpoint of a Marimo notebook application, which indicates an attempt to exploit CVE-2026-39987, a pre-authentication Remote Code Execution vulnerability involving WebSocket connections.
Detects network traffic attempting to exploit CVE-2021-33044, an authentication bypass vulnerability in Dahua NetKeyboard devices, by identifying specific login request strings used in the exploit chain.
Detects repeated authentication login attempts (opcode 0xA0) against Dahua Easy4IP devices over TCP port 37777, indicative of a brute-force or credential stuffing attack.
Detects network activity related to the exploitation of the CVE-2025-31702 vulnerability in Dahua P2P Relay services. The rules monitor for probe attempts, device parameter fetching (randsalt), serial number enumeration bursts, and successful no-auth channel responses, indicating a bypass of authentication mechanisms on vulnerable Dahua devices.
This rule detects a specific network exploit attempt targeting Dahua devices (CVE-2021-33045), where an attacker attempts to bypass authentication by manipulating the login parameters, specifically by forcing the system to interpret requests as coming from the local loopback interface.
Detects attempts to exploit CVE-2021-33044, an authentication bypass vulnerability in Dahua NetKeyboard hardware. The rule triggers when a POST request containing 'global.login', 'clientType: NetKeyboard', and 'loginType: Direct' is observed, which allows unauthorized access by manipulating authentication parameters.
This rule detects an attempt to exploit CVE-2021-33045, an authentication bypass vulnerability in certain Dahua products. An attacker can bypass authentication by sending a crafted HTTP POST request to the application, specifically using a loopback authentication type with a local IP address (127.0.0.1) in the login payload.
Detects high-concurrency brute-force attempts against Dahua Easy4IP-enabled devices targeting port 37777, identified by specific binary patterns (opcode 0xA0) in the packet payload. This indicates an automated attempt to compromise device authentication.
This rule detects an attempted authentication bypass vulnerability (CVE-2021-33045) targeting Dahua NetKeyboard devices. The exploit involves a specific HTTP request structure to the 'global.login' endpoint, where the 'loginType' parameter is set to 'Loopback' and the 'ipAddr' is set to '127.0.0.1', attempting to leverage internal loopback logic to circumvent authentication mechanisms.
Detects repeated authentication login attempts (opcode 0xA0) against Dahua Easy4IP devices over TCP port 37777, indicative of a brute-force or credential stuffing attack.
Detects network traffic associated with exploitation attempts against Dahua P2P relay services. The rules monitor for specific URI patterns ('/online/p2psrv/' and '/probe/device/') used to probe the device, as well as traffic containing a hardcoded AES-OFB initialization vector, which indicates attempts to exploit CVE-2025-31702.
Detects network packets targeting the Dahua SDK service (port 37777) that match the signature of a crafted login request, specifically checking for the 0xFF/0x00 magic header and the 0x00/0xA0 opcode. This pattern is commonly associated with unauthorized authentication attempts, including brute-force attacks or exploitation of known authentication bypass vulnerabilities in Dahua devices.
Detects malicious activities associated with the SilkParasite campaign targeting Redis servers. The rules identify the initiation of a 'SLAVEOF' command to a rogue replication host, subsequent handshake (PSYNC/REPLCONF) with an external attacker-controlled node, and the modification of server configuration ('CONFIG SET dbfilename') to potentially facilitate unauthorized file persistence or data exfiltration through the Redis replication mechanism.
