The Attack Surface
Using the ‘XPRV’ Master Key incorrectly opens a myriad of vulnerabilities, making it crucial to understand the attack vectors. If you misconfigure access or expose your key through nefarious means, the risks become tremendous. Cybercriminals can exploit weak points in hardware, use phishing tactics, or manipulate firmware vulnerabilities – with potentially devastating outcomes for your assets. The chance of an unauthorized party emptying your wallet increases exponentially with every misstep.
