is a legacy utility software used for reading, managing, and occasionally cloning GSM Subscriber Identity Module (SIM) cards. While largely obsolete for modern 4G and 5G security standards, it remains a notable tool in the history of mobile forensics and GSM security research. Core Functionality

Understanding Woron Scan 1.09: The Legendary SIM Cloning and Decoding Tool : Beyond security testing, it includes basic features

SimScan and Woron Scan were competing third-party tools developed around the same time for similar purposes. Both were designed to work with SIM readers to extract the Ki. Some users found one worked better for specific cards or setups than the other, and they were often used in tandem during the troubleshooting process.

In practice, if you search GitHub or SourceForge for "woron109," you will find a handful of abandoned projects and shell scripts. Tech enthusiasts have reverse-engineered the protocol and implemented partial clones, but the "true" Woron Scan 109 remains a semi-legendary tool passed around on USB sticks at hacker camps.

) and International Mobile Subscriber Identity (IMSI). Once these are extracted, they can be written to a programmable "Silver" or "Gold" wafer card to create a functional clone. Phonebook and SMS Management Only very early GSM SIM cards (typically manufactured

Most modern SIM cards use updated algorithms like COMP128v2 or v3, which are specifically designed to resist the collision-based attacks used by Woron Scan. Université catholique de Louvain needed to run this software or how to protect modern SIM cards from similar attacks?

: It was designed to work with smart card readers/programmers and blank programmable cards (often referred to as "wafer cards" or "Silver/Green cards"). Nairobi Business Monthly Technical Limitations & Risks COMP128v1 Vulnerability : Woron Scan relies on a security flaw in the

The core action involves selecting the "Scan KI" function. The software begins transmitting a heavy stream of pseudo-random challenges to the SIM. Depending on the speed of the processor and the specific card generation, discovering all 8 pairs of the Kicap K sub i key can take anywhere from 30 minutes to several hours. Step 4: Cloning (Optional Security Testing) Once the IMSI and Kicap K sub i

Woron Scan 109 cannot function purely via software; it requires a physical bridge to talk to the ISO 7816 smart card interface used by SIM cards. Historically, this required:

It creates a map of all addressable blocks, excluding bad block lists already stored in the device’s G-List (grown defect list) or P-List (primary defect list).
