The marketing term "exclusive software download" usually serves as a lure. In reality, this software is rarely proprietary or exclusive; it is often open-source hacking tools or cracked versions of professional forensic software repackaged for consumers. The process is technically demanding. It requires a USB SIM card reader and often involves "brute-forcing" the SIM card’s encryption to extract the Ki (Authentication Key). While this may have been feasible with older 2G COMP128 v1 encryption, modern 3G, 4G, and 5G SIMs utilize much stronger encryption (such as COMP128 v2/v3) that is virtually impossible to clone via standard consumer hardware.
