Modern telecommunication networks no longer use the weak COMP128v1 cipher. Current mobile network operators utilize advanced , TU3 , or AES-128 cryptographic algorithms embedded within high-security USIM cards. These modern chips feature advanced physical and mathematical countermeasures against side-channel analysis and power profiling. Consequently, modern SIM cards completely block extraction software like Woron Scan, rendering any brute-force attempt futile. Legal and Compliance Boundaries
Because Woron Scan 109 is a legacy tool, modern USB-C diagnostic links will not work with it natively. It requires a specific hardware ecosystem. The Interface Cable
: Scanning a SIM card involves sending thousands of challenges to it. Some service providers implement "self-destruct" counters; if the software exceeds a certain number of attempts, the SIM card may permanently lock (become "bricked"). Legacy Status
Woron Scan is a dedicated software application designed to work with SIM card readers. Its primary function, as described in community forums and technical guides, is to extract the from a SIM card. The Ki is a 128-bit secret key used in the GSM authentication process. Once the Ki is obtained, along with the IMSI (International Mobile Subscriber Identity) , it becomes technically possible to create a clone of the original SIM card. woron scan 109
The software is designed to communicate with a SIM card via a hardware smart card reader (typically Phoenix or Smartmouse compatible). Its primary function is to read and manage the data stored on the Integrated Circuit Card Identifier (ICCID) and International Mobile Subscriber Identity (IMSI). Core Features
The interface of Woron Scan 109 is rudimentary by modern standards, reflecting its origin in the Windows 98/XP era. However, it packaged several complex smart card protocols into an accessible GUI:
If the file system is corrupt, the Woron Scan 109 attempts to reconstruct directory entries by scanning for known file signatures (JPEG headers, PDF footers, ZIP central directories). Modern telecommunication networks no longer use the weak
What environment are you running the tool on? What specific hardware reader/programmer model do you have?
This process could take a significant amount of time. Users reported waiting for "40 min" to several hours, with the software attempting millions of calculations to eventually reveal the Ki string. The software also offered advanced settings for experienced users, such as the "A38 limit" and the "Strong Ki" toggle, which were used to adjust the brute-force strategy for different card types.
Locate the USB Serial Port and assign it to (Woron Scan typically only scans low-numbered ports). The Interface Cable : Scanning a SIM card
Early GSM networks relied on an authentication algorithm known as . This algorithm suffered from a severe cryptographic flaw known as differential power analysis and side-channel leakage .
Based on detailed technical documentation from Chinese-language sources, using Woron Scan 1.09 is often a multi-step process that involves other utilities:
Woron Scan 109 was built for 16-bit and 32-bit Windows environments. It struggles on modern 64-bit systems like Windows 10 or Windows 11. Researchers generally run the utility inside a virtual machine or a dedicated legacy sandbox environment running: Windows XP Windows 98 / Me 📊 COMP128 Mutation & SIM Compatibility
