Detects potential execution of MeshAgent, a remote access tool, on macOS systems. The rule specifically looks for the '--meshServiceName' argument in the command line, which is indicative of MeshAgent usage. Threat actors often rename the MeshAgent binary to evade detection, making command-line arguments a more reliable indicator.

This query helps you design client firewall rules based on data stored within DeviceNetworkEvents. Folder paths are alias'ed to help represent the
files making or receiving network connections without dealing with duplication from path variance due to different root drive letter or user profile
association.
To make the report easy to read, inbound remote IP addresses are not calculated by default (this can be changed by setting the value of IncludeInboundRemoteIPs to true).
Also, the ephemeral range is defaulted to 49152 to help eliminate false detections.

Snip3 is a family of related remote access trojans. Although the malware in this family contain numerous small variations, they all exhibit similar behaviors and techniques.
The following query looks for a function call to a method named DetectSandboxie. This method is used in RevengeRAT and AsyncRAT instances involved in a campaign targeting the aviation industry, first observed in 2021. It has also been associated in the past other malware, such as WannaCry and QuasarRAT. Individual PowerShell functions can be detected in the same way in some instances, though care should be taken to ensure that the command name is unique -- otherwise, this query may return many false positives.
