Woron — Scan 1.09

Developed during the golden era of hardware hacking in the early 2000s, this lightweight software became the global gold standard for telecom enthusiasts, security researchers, and casual hobbyists looking to back up cellular identities or consolidate multiple mobile subscriptions into a single "Multi-SIM" card.

: Implemented fixes to eliminate the byte leakage that Woron Scan relied on, rendering basic software brute-forcing ineffective.

Once the Ki and IMSI are obtained, a user can write these credentials onto a blank, programmable smart card (historically referred to as "Silver cards" or "Green cards"), effectively creating a functional clone of the original mobile identity. Modern Limitations: Why It Failed on Newer Cards

The software will begin sending thousands of challenges to the SIM card to analyze its responses. Timeframe: This can take anywhere from 30 minutes to several hours. Developed during the golden era of hardware hacking

Obtain woronscan.exe from a trusted archived repository (more on safety below). Place it in any folder and double-click. No installation or administrative privileges are strictly required, though some advanced scans may need admin rights for raw sockets.

Beyond security testing, it allowed users to read, edit, and recover deleted SMS messages and phonebook entries directly from the SIM storage. Once the Ki and IMSI are obtained, a

: It breaks down the 128-bit key byte-by-byte, significantly shortening the time required to guess the actual Ki.

Using Woron Scan was far from a guaranteed success. Users on forums frequently reported problems. Some cards were resistant and would stop scanning after hours of effort. Others were completely incompatible; for instance, the infamous or A38 bug was a significant hurdle. The A38 limit represented a specific number of authentication attempts that some SIM cards would allow before they locked up or stopped responding, effectively preventing the scan.

The specific version 1.09 is notable in the timeline. According to discussions on dedicated GSM forums, the final version of the original tool was . An interesting quirk is that when hovering over the executable file, it might incorrectly report a different version (e.g., 1.0.0.1 ), which was reportedly due to the original author forgetting to update the version number before compiling the final build.

Upon launching, the software initializes the card reader.
