Detects network or system activity associated with the 'p2pwn' backdoor account on Dahua cameras, which is introduced by exploiting the CVE-2024-39943 vulnerability. The rule monitors for the presence of 'p2pwn' and 'p2password' strings across logs, including RPC/login events.
This rule detects potential exploitation attempts targeting the CAPWAP (Control and Provisioning of Wireless Access Points) protocol in FortiOS or FortiSwitchManager. The rule identifies suspicious UDP traffic on port 5246 containing an oversized payload (greater than 1400 bytes), which is characteristic of the exploitation pattern for CVE-2025-25249.
This rule identifies MikroTik devices running vulnerable versions of RouterOS (specifically those older than 7.24) that are susceptible to CVE-2026-84411. This vulnerability involves an integer underflow in the web management HTTP handling, which can lead to unauthenticated remote code execution or denial of service.
This rule detects potential exploitation of CVE-2026-86134, a NULL pointer dereference vulnerability in WatchGuard Fireware. It identifies a burst of authentication-related requests (login, authd, management) targeting a device, followed by system logs indicating a service crash, daemon restart, or core dump within a short correlation window. This behavior is indicative of a Denial of Service attack.
Detects a sequence of events characteristic of exploitation against RouterOS (CVE-2026-67276/CVE-2026-86060), involving a failed SSH login attempt with the username '-2', followed by the creation of a new user account within the same SSH session, and a successful login with that newly created account.
Detects evidence of an argument-injection attack against MikroTik RouterOS (CVE-2026-86060), where the attacker provides the literal username '-2' during the login process. This action allows the attacker to bypass standard credential validation by exploiting a forged privilege mask. This is typically observed in conjunction with unauthorized access attempts following CVE-2026-67279.
This rule detects potential exploitation of CVE-2026-86134, a NULL pointer dereference vulnerability in WatchGuard Fireware. It identifies a burst of authentication-related requests (login, authd, management) targeting a device, followed by system logs indicating a service crash, daemon restart, or core dump within a short correlation window. This behavior is indicative of a Denial of Service attack.
Detects anomalous SSH login attempts using the username '-2', which exploits a known argument-injection vulnerability (CVE-2026-86060) in MikroTik RouterOS. This vulnerability allows an attacker to bypass authentication and obtain unauthorized administrative privileges by forcing the login process to read privilege levels from the terminal file descriptor.
Detects anomalous activity on Dahua camera management interfaces (port 37777) where multiple failed authentication attempts are followed by administrative configuration actions without a corresponding successful credentialed login, suggesting exploitation of authentication-bypass vulnerabilities such as CVE-2021-33044 and CVE-2021-33045.
Detects a sequence of events characteristic of exploitation against RouterOS (CVE-2026-67276/CVE-2026-86060), involving a failed SSH login attempt with the username '-2', followed by the creation of a new user account within the same SSH session, and a successful login with that newly created account.
Detects an exploitation chain in RouterOS where an attacker triggers an SSH rekey before authentication completes, forcing the SSH server into a post-authentication state. This allows the attacker to execute arbitrary commands over an unauthenticated channel, leading to unauthorized creation, modification, or reconstruction of sensitive system and configuration files.
Detects potential command injection attempts or unauthorized access attempts directed at WatchGuard Access Point management interfaces, identified by suspicious strings typically used in exploitation payloads within device logs.

Detects a sequence of events characteristic of exploitation against RouterOS (CVE-2026-67276/CVE-2026-86060), involving a failed SSH login attempt with the username '-2', followed by the creation of a new user account within the same SSH session, and a successful login with that newly created account.
Detects unauthorized or suspicious configuration changes on Cisco IOS XR devices, specifically targeting the creation of SPAN/mirroring sessions, ACL modifications to bypass traffic filtering, and changes to AAA or local user authentication settings. These patterns are consistent with post-compromise activities by adversaries seeking persistence and traffic interception.
Detects anomalous, oversized fragmented UDP traffic (exceeding 1400 bytes) targeting or originating from the MikroTik btest service port (2000). This behavior is indicative of attempts to trigger integer underflows, system crashes, or uninitialized memory disclosures within the btest protocol implementation.
This rule detects potential attempts to exploit an SSH pre-authentication rekey or authentication bypass vulnerability (CVE-2026-67279) in MikroTik RouterOS devices. It monitors incoming TCP traffic on port 22 that contains the 'ROSSSH' signature followed by specific binary sequences indicative of exploitation attempts.
Detects the creation of an administrative-level user account (e.g., 'ops') on a MikroTik RouterOS device shortly after an anomalous login attempt using the '-2' username. This sequence is indicative of the exploit chain associated with specific MikroTik RouterOS vulnerabilities where an unauthenticated or specially crafted login is used to facilitate unauthorized user creation.
Detects the presence of an unauthorized administrative account (e.g., 'ops') on MikroTik RouterOS devices following a system 'Flagged' indicator. This rule correlates administrative account creation or modification events with system-reported compromise indicators to identify post-exploitation persistence mechanisms related to known RouterOS vulnerabilities.
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.
