Travelers who refuse face immediate deportation, entry denial, or equipment seizure. In inspection facilities, border agents deploy forensic hardware like Cellebrite UFED or GrayKey to bypass lockscreens over USB ports, dump flash partitions, and map financial applications.\u003C\u002Fp>\n\u003Ch3 id=\"2-targeted-extortion-and-physical-coercion\">2. Targeted extortion and physical coercion\u003C\u002Fh3>\n\u003Cp>Violent robberies targeting visible Web3 investors are increasingly common in major tourist hubs and global financial centers.
