Intelligence Profile

According to Lumen, J-Magic is a variant of cd00r and passively scans for five different predefined parameters before activating. If any of these parameters or “magic packets” are received, the agent sends back a secondary challenge. Once that challenge is complete, J-magic establishes a reverse shell on the local file system, allowing the operators to control the device, steal data, or deploy malicious software.
