| T1437.001 | Web Protocols |
Adversaries may communicate using application layer protocols to avoid detection/network filtering by blending in with existing traffic. Commands to the mobile device, and often the results of those commands, will be embedded within the protocol traffic between the mobile device and server.
Adversaries may utilize many different protocols, including those used for web browsing, transferring files, electronic mail, or DNS.

| S1083 | Chameleon | |
| S1243 | DCHSpy |
DCHSpy has uploaded collected data to a Secure File Transfer Protocol (SFTP) server.[2] |
| S0550 | DoubleAgent |
DoubleAgent has used both FTP and TCP sockets for data exfiltration.[3] |
| S1054 | Drinik |
Drinik has code to use Firebase Cloud Messaging for receiving C2 instructions.[4] |
| C0054 | Operation Triangulation |
During Operation Triangulation, the threat actors used HTTPS POST requests for C2 communication.[5] |
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
