Users could read, edit, and backup contacts stored directly on the SIM card.
Frequent "brute force" scanning can occasionally "kill" or lock a SIM card if the internal counter for authentication attempts is reached. Conclusion
The effectiveness of Woron Scan 1.09 is tied to the authentication algorithm. This early algorithm had a cryptographic flaw that allowed the KI to be "cracked" if enough queries were sent to the card. Woron Scan 1.09 Software
It provided tools to view the PIN/PUK status and other technical files (EF - Elementary Files) within the SIM's file system. The Technical Context: Comp128v1
SIM cloning and unauthorized access to GSM data may be illegal in your jurisdiction. This software should only be used for educational purposes or on SIM cards you personally own for data recovery. Users could read, edit, and backup contacts stored
Understanding Woron Scan 1.09: A Tool for SIM Card Analysis In the niche world of GSM security and SIM card management, remains a frequently discussed piece of legacy software. While the mobile industry has moved toward more secure USIM and eSIM technologies, this utility serves as a historical benchmark for understanding how early SIM cards functioned and how their internal data was accessed.
Specifically one that supports Phoenix or Smartmouse mode (typically using a COM port or a USB-to-Serial bridge). This early algorithm had a cryptographic flaw that
The most "famous" feature of Woron Scan is its ability to extract the KI from older Comp128v1 SIM cards. By running a series of challenges against the card, the software could deduce the key used for network authentication.
