By fuzzing the cellular stack (specifically Layer-2 and Layer-3), researchers have successfully discovered vulnerabilities that can crash basebands. Connect the device to the PC while holding
While defenders cannot see the code, determined attackers can reverse-engineer the binary firmware. Tools like IDA Pro and Ghidra allow researchers to disassemble these binary blobs. Historically, this asymmetry favors the attacker. Once a vulnerability is found in a specific BP model (e.g., a stack overflow in the parsing of a GSM cell broadcast message), it affects millions of devices simultaneously. it affects millions of devices simultaneously.
