The primary vulnerability is the outdated COMP128-1 algorithm, which has been replaced in nearly all modern SIM cards.
The software can change PIN1 codes or unblock PIN/PUK attempts.
Requires outdated hardware and operating systems for stability.

Let’s compare this legacy tool to three popular modern solutions:
If you lost your SIM card, you lost your contacts. Having a clone meant a backup was always ready. Dual-SIM Workarounds:
The software interacts with the SIM's microcontroller to retrieve critical identifiers:
Users report that the software requires specific hardware, such as an RS232-based SIM reader or a USB-to-RS232 converter, to interface correctly with the PC. Summary of Pros and Cons Historically reliable for V1 SIM card cloning. High risk of permanently damaging (bricking) the SIM card. Simple interface for basic GSM data extraction. Does not work with modern, secure SIM cards. Works well with legacy hardware readers.

Based on forum discussions from the mid-2000s, Woron Scan was a tool for users who wanted to:
Because Woron Scan 1.09 is no longer supported or updated by an official developer, it is frequently hosted on unverified third-party software archives, forum threads, and file-sharing directories.
