Malware can be preinstalled, delivered during the initial installation of the wallet, or pushed through a removable media. Once the malware is installed, there are a variety of exfiltration methods an attacker can use, and Guri evaluated several, including physical, electromagnetic, electric, magnetic, acoustic, optical and thermal.
