A unique, publicly readable identification number used by the carrier network to recognize the device.

If you are interested in exploring similar tools or learning more about network security protocols, I can provide information on modern methods for securing SIM cards or digital forensics tools.

In the realm of telecommunications security and digital forensics, certain older software tools hold a significant place in history for their ability to interact with and analyze Subscriber Identity Module (SIM) cards. One such classic application is , a utility primarily used for scanning and extracting information from SIM cards that utilize the COMP128-1 authentication algorithm.

Users can view, edit, and export the SIM's stored contacts.

Insert the target SIM card into the SIM reader and connect the reader to the computer's COM port or USB-to-serial adapter. Launch the driver software provided with your reader.

: The tool can extract and archive stored text messages.

The intensive "brute-force" scanning process has a significant risk of permanently burning out or damaging the SIM card.

The software saves scans as uncompressed BMP or high-quality JPEG at user-defined levels (1–100). It does not add metadata, watermarks, or color profiles—just the raw sensor data.

: Woron Scan sends millions of challenges to the SIM card, analyzing the resulting responses to slowly piece together the secret 128-bit Ki key.

To extract data using Woron Scan 1.09, hardware and software components must operate in lockstep. The typical legacy workflow includes:

. Modern research has shown that this process can take relatively few queries compared to modern standards. The Role of Woron Scan in Modern Security
