Exfiltration Over Other Network Medium

From MITRE ATT&CK 19.2
Adversaries may attempt to exfiltrate data over a different network medium than the command and control channel. If the command and control network is a wired Internet connection, the exfiltration may occur, for example, over a WiFi connection, modem, cellular data connection, Bluetooth, or another radio frequency (RF) channel.
Adversaries may choose to do this if they have sufficient access or proximity, and the connection might not be secured or defended as well as the primary Internet-connected channel because it is not routed through the same enterprise network.

How MITRE says to detect it DET0077
Detection of Exfiltration Over Alternate Network Interfaces
Windows Analytic 0212
Execution of file transfer or network access activity through non-primary interfaces (e.g., WiFi, Bluetooth, cellular) by processes not typically associated with such behavior (e.g., rundll32, powershell, regsvr32).
WinEventLog:SysmonEventCode=3, 22WinEventLog:SystemEventCode=5005 (WLAN), EventCode=302 (Bluetooth)WinEventLog:SysmonEventCode=11
Linux Analytic 0213
Use of `rfkill`, `nmcli`, or low-level tools (e.g., `iw`, `hcitool`, `pppd`) to enable alternate interfaces followed by data transfer via non-primary NICs.
auditd:SYSCALLNoneNSM:FlowNone
macOS Analytic 0214
AppleScript or system calls to activate WiFi/Bluetooth interfaces (`networksetup`, `blueutil`), followed by exfiltration via AirDrop, cloud sync, or network socket.
