| Parameter | Description |
|-----------|-------------|
| <source> | Internal path: /models/, /settings/, /firmware/ or specific file like model1.bin |
| <destination> | External destination on the host (e.g., serial: or virtual mount point) |
In incident response, you may have a memory dump from a compromised server. Attackers often use process_vm_readv to extract credentials from a database process. .getxfer can scan the kernel's memory transfer logs (if instrumented) or parse Page Map Entry (PME) structures to identify large buffer moves, helping you recover exfiltrated data. .getxfer
When the target function is called, .getxfer intercepts the arguments: source pointer, destination pointer, and number of bytes to transfer. Modern malware may:
The .getxfer command is used to initiate a data transfer from the radio’s internal memory to an external device (usually a PC running the OpenTX Companion software or a custom script). It typically retrieves model data, radio settings, or firmware-related binary blobs. explicit contracts: get what you need
Modern malware may:
.getxfer sits at an intersection: a technical affordance for robust transfers and a metaphor for the way data — and by extension, responsibility — moves between systems and people. Its terse name encourages minimal, explicit contracts: get what you need, transfer what you must, prove what you moved.
