Click Tasks -> Ki search . A popup window will appear. Click the Search button. The software will begin sending calculations to the SIM card. It is advised to select the "Alternate Decoding Method" if your card is not responding with standard algorithms. Wait for the process to complete. This is the longest phase, potentially taking up to 3-4 hours. Once finished, record the resulting Ki values.

The software was built for Windows XP and 98. Running it on Windows 10 or 11 usually requires "Compatibility Mode" or a Virtual Machine.

Understanding Woron Scan 1.09: The Legacy SIM Tool Woron Scan 1.09 is a piece of legacy software that was once widely used by hobbyists and researchers to interact with and analyze SIM card data. Frequently searched for as "woron scan 109 free," it became a staple in the early days of mobile technology for those looking to explore the inner workings of GSM cards.

Over the past few months, my analytics dashboard has seen a 40% spike in searches for this exact term. Curiosity is peaking. But as a security researcher who has spent years cleaning malware off compromised machines, I am here to sound the alarm.

: In many jurisdictions, cloning a SIM card or accessing its security keys without authorization is illegal. It is primarily used today by security researchers or hobbyists working with legacy hardware. Click Tasks -> Ki search

Why does version 109 remain popular years after its release? The answer lies in its robust feature set:

: It generally only works with older GSM (2G) cards. Modern 3G, 4G, and 5G cards use much stronger encryption (Comp128v2/v3 or Milenage) that Woron Scan cannot crack. The software will begin sending calculations to the SIM card

This early GSM authentication algorithm contained mathematical flaws allowing the Ki to be deduced through a brute-force side-channel collision attack (often requiring between 50,000 to 150,000 targeted queries). Woron Scan automates this specific attack.

: The tool is most notable for its ability to attempt to extract the Ki (Authentication Key). This was historically used to clone older GSM "V1" SIM cards, which used a vulnerable authentication algorithm.

) from older COMP128v1 SIM cards, which is the necessary step for cloning.
