Detects network communication associated with the SilkParasite campaign. This includes detection of TLS traffic using self-signed LokiDev certificates (CN=localhost, O=LokiDev), direct connections to known malicious C2 IP addresses, and DNS queries for the domain normativ.dushanbeidc.org, which is linked to the LokiDev infrastructure.
Detects network communication associated with the SilkParasite campaign, specifically identifying TLS traffic using fraudulent certificates impersonating the Uzbekistan railway authority (azure.uzrailwaystax.com) and connections to identified malicious infrastructure using specific JA4X TLS fingerprinting.
Detects outbound RDP-over-TLS connections using non-standard high-numbered ports (64350, 64330, 65535, 65111, 61256), characteristic of SilkParasite command and control infrastructure. The rules trigger on known C2 IP addresses and general suspicious RDP behavior on these specific ports.
Detects high-frequency TCP connection attempts to port 37777, commonly associated with Dahua surveillance devices. The rule uses a threshold of 200 connection attempts within 60 seconds from a single source, which is characteristic of mass-scanning or brute-force activity.
Detects network communication to known SpiceRAT Command and Control (C2) IP addresses and DNS queries for known SpiceRAT-related domains. The rule identifies potential compromise by flagging outbound traffic or DNS resolutions associated with SpiceRAT infrastructure.
Detects high-frequency login attempts directed at the Dahua Easy4IP SDK port 37777, consistent with automated brute-force toolkits like async_brute.py. The rule monitors for a specific packet sequence indicating authentication attempts within a short timeframe.
Detects network traffic attempting to impersonate the Uzbekistan railway authority via suspicious TLS certificates. The rules identify specific SNI domains, certificate subjects, and issuers associated with the 'SilkParasite' campaign, which uses Chinese state-affiliated certificate authorities to facilitate C2 communications.
Detects RDP-over-TLS/NLA traffic occurring over non-standard high ports, which is often indicative of C2 communication or lateral movement associated with the SilkParasite infrastructure cluster.
Detects outbound network traffic from internal hosts to known IP addresses associated with the SpiceRAT malware command and control infrastructure.
Detects network traffic attempting to exploit CVE-2021-33044 in Dahua NetKeyboard devices. The rule identifies specifically crafted 'global.login' requests designed to bypass authentication mechanisms.
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.
Detects outbound TLS-encrypted network traffic directed towards known SilkParasite infrastructure using non-standard high ports commonly associated with RDP-over-TLS (NLA). The rule identifies potential Command and Control (C2) activity by flagging connections to suspicious IP/port combinations typical of this adversary cluster.
Detects network communication associated with the SilkParasite campaign, specifically targeting TLS connections that use spoofed certificates impersonating azure.uzrailwaystax.com or communication with known SpiceRAT command-and-control server IP addresses.
Detects high-frequency, unauthenticated probe requests targeting Dahua P2P relay endpoints (/probe/device/ and /online/p2psrv/). This activity is indicative of automated scanning, enumeration, or potential exploitation attempts related to CVE-2025-31702 against internet-facing or network-connected Dahua hardware.
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 network communications between internal hosts and known malicious infrastructure associated with SpiceRAT, including TLS-based command channels and HTTP requests for decoy pages.
Detects network activity associated with the SilkParasite C2 infrastructure (used by SpiceRAT and NodeEdgeRAT malware). The rule monitors for specific impersonated TLS certificates, known malicious IP addresses, and unique JA4X TLS fingerprints associated with these threat actors.
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 malformed SCTP packets that trigger a protocol decoding error ('pkt_too_small'). This behavior is associated with the 'DiagSpill' vulnerability (CVE-2026-74469), where specially crafted chunk sequences in the SCTP stream can cause a remote service crash or potential instability. The rule includes a threshold to mitigate noise from non-malicious malformed packets.
This rule detects network activity associated with the SilverFox malware, specifically targeting communication patterns between the compromised host and identified relay infrastructure. The detection focuses on unique URL query patterns for relay discovery and dispatcher requests, as well as the identification of staging/download links within server responses.
Detects network activity associated with the Rapuncel malware, including raw TCP exfiltration of files via POST requests to /upload, connections to known malicious C2 infrastructure, and repeated exfiltration retry patterns.
