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.
This rule detects the execution of processes containing 'OnvifUser' and command line arguments specifying '-u', which is consistent with the usage of ONVIF device discovery tools. ONVIF discovery protocols are used to identify network video transmitters. Unauthorized use of these tools can indicate reconnaissance activity within a network to identify cameras or video surveillance devices.
This rule detects various system events (including process execution and user account creation) that contain the specific string 'p2pwn' in combination with the string 'p2password'. This pattern suggests the activity involves potentially malicious credential testing, hardcoded credential usage, or suspicious account interaction activity.
Detects the presence of PNG image files containing a specific steganographic marker embedded within the iTXt metadata chunk, often used by the LausivLoader malware for C2 communication or payload delivery. The rule looks for the specific marker 0xFF89AD4A or known C2 indicators (yapw.life, stego_zrgaixkku8.png) within PNG files.

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.
Detects network communications between internal hosts and known malicious infrastructure associated with SpiceRAT, including TLS-based command channels and HTTP requests for decoy pages.
