Network-Optimized Technical Synopsis:

How Are SIM Cards Attacked?
A SIM card represents the user's identity within the GSM network, making the security of its components critically important. Due to this significance, various attacks targeting SIM cards are constantly emerging. From the user’s perspective, attacks on SIM cards primarily fall into two categories: Disrupting the user’s normal access to network services.Gaining economic benefits by intercepting the SIM card or obtaining the transmitted encryption key (Ki).

Similar to computer operating systems, mobile operating systems often contain vulnerabilities due to design flaws or oversight—such as failing to disable backdoor code originally intended for testing purposes. These weaknesses create exploitable gaps for attackers. One common method involves sending specially crafted text messages that target these vulnerabilities, causing internal program errors in the phone’s operating system and rendering the device inoperable.
