Woron Scan 1.09 =link= Jun 2026

is a specialized, legacy software utility designed for interacting with GSM SIM cards. In the early-to-mid 2000s, it gained prominence in the "telecom underground" as a powerful tool for retrieving sensitive data, specifically the IMSI (International Mobile Subscriber Identity) and the KI (Authentication Key) from SIM cards. Functional Overview

In the realm of SIM card analysis, cloning, and security auditing, remains a legacy tool, recognized for its efficiency and speed in interacting with older generation SIM cards. While modern smartphones have evolved significantly, the principles behind SIM card technology, specifically the extraction of identification keys, remain relevant for researchers, forensic investigators, and users looking to manage multiple SIM cards on a single multi-SIM adapter.

A secret 128-bit cryptographic key assigned by the carrier. The network uses the Ki to authenticate the device through a challenge-response handshake without ever sending the key itself over the air. The Evolution: Woron Scan vs. Sim-Scan Woron Scan 1.09

: Designed for Comp128v1 authentication algorithms, which were standard on early GSM cards but have since been replaced by more secure versions. Technical and Safety Limitations

I ran the "Refresh Sectors" (Write/Read) function on that specific LBA range. After 45 minutes, the software reported "19 sectors remapped, 4 sectors remain unreadable." The drive passed a second full scan with only 4 orange blocks. I rebooted into XP, ran chkdsk /r , and the OS booted perfectly. That drive lasted another 3 years as a backup.

The tool targeted two distinct data fields embedded within the microchip:

Modern PCs do not have floppy drives, but you can use Rufus to create a bootable FreeDOS USB stick. Copy WSCAN109.EXE to the root of the drive.
