Detects autonomous behavior where AI-driven processes attempt multiple network connections (SMB, SSH, HTTP, RDP, WinRM) to diverse targets following failed access attempts. The rule correlates initial failure activity with subsequent credential-related events and new lateral movement traffic from the same agent process within a short window, suggesting adaptive adversary pivoting.

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.

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.

0011
Detects the execution of command interpreters or scripting engines spawned by the ManageEngine ADSelfService Plus GINA client process (typically present at the Windows logon screen). This activity is highly suspicious as it indicates potential command injection or abuse of a pre-authentication component running at SYSTEM privileges.

This rule detects unauthorized or unauthenticated attempts to call the NetrServerPasswordSet2 method on a Domain Controller via the MS-NRPC (Netlogon) interface, which is indicative of an exploitation attempt related to CVE-2020-1472 (Zerologon). This vulnerability allows an attacker to bypass authentication and reset a Domain Controller's computer account password, leading to full domain compromise.

Detects rapid, machine-speed, sequential attack-path adaptation by suspected AI agent binaries. The rule monitors for a correlation of four stages occurring within a tight 20-minute window: 1) Failed service connections across three or more distinct protocols (SMB, SSH, HTTP, RDP, WinRM), 2) Credential access attempts (Logon events or execution of known credential-dumping tools), and 3) A lateral movement pivot to a new, previously un-targeted internal destination. The rule specifically keys on the InitiatingProcessId and InitiatingProcessCreationTime to ensure the sequence is attributed to a single process instance, distinguishing it from human manual penetration testing activity. Covers T1190, T1210, T1078

Detects signs of Zerologon (CVE-2020-1472) exploitation by correlating Netlogon (MS-NRPC) authentication anomalies involving known exploitation tools/process names with subsequent machine-account password reset events (Event ID 4742) occurring on the same device within a short time window.
