Detects the execution of MeshCentral remote management agent (meshagent.exe) or activity associated with its default installation paths and markers. MeshCentral is legitimate remote access software that can be abused by adversaries for persistence and command-and-control access.

Detects the execution of MeshCentral remote management agent (meshagent.exe) or activity associated with its default installation paths and markers. MeshCentral is legitimate remote access software that can be abused by adversaries for persistence and command-and-control access.
Detects the installation or execution of common remote monitoring and management (RMM) tools, including AnyDesk, TeamViewer, ScreenConnect, and Quick Assist. These tools are frequently abused by adversaries for persistence and command-and-control post-compromise.
Detects a host making 3 or more outbound connections within 5 minutes to AWS-hosted IP addresses known to host NJRAT C2 infrastructure from the GTA6 lure campaign, consistent with periodic RAT beaconing rather than a one-off incidental connection.

This rule detects potential VNC remote access activity by identifying systems that exhibit both the presence of specific VNC configuration/history files (AccInfo.ini, History.txt) and concurrent network activity on port 10635, which is commonly associated with VNC-like remote access tools.
Detects the installation or execution of known remote access tools (RMM) from suspicious parent processes (browsers, archives) or from user-writable directories (Temp, Downloads). This behavior is characteristic of initial access and staging activities performed by ransomware operators or Initial Access Brokers (IABs). The rule excludes known IT-managed deployment paths and signed binaries used by the organization.
Detects unauthorized remote access sessions within N-able N-central by monitoring the Windows Application log for events indicating usage of the default 'MSP Support' account or source IP addresses associated with active exploitation of CVE-2026-18577.

Detects network traffic between internal hosts and a known malicious IP address on port 5556, characteristic of Go_RAT (hVNC) command and control communication. This rule monitors for established TCP connections to identify potential C2 beaconing or active remote management sessions by the GapiUpdate campaign.

Detects the execution of 'famitrf2.exe' when it is launched as a child process of 'rserver3.exe' from the specific path 'C:\intel\rserver\rserver3.exe'. This pattern is highly indicative of Remote Administrator (RAdmin) software activity, which can be leveraged for legitimate remote management or malicious remote access.
Detects outbound network traffic from internal hosts to known MeshCentral Command and Control (C2) infrastructure. MeshCentral is legitimate remote monitoring and management (RMM) software that is frequently abused by threat actors to maintain persistent remote access to victim environments. This rule monitors for established TCP connections on specific ports associated with MeshCentral C2 nodes.
