Unauthorized cloning of SIM cards is illegal in many jurisdictions, as it facilitates unauthorized network access, interception of calls/messages, and potential identity theft 4.2.4 .
Because of an architectural flaw in Comp128v1, the card’s processor leaked information regarding the internal state of the secret Ki key during these authentication rounds.
Newer generations of network technology, such as 4G LTE and 5G, employ mutual authentication. This requires not only the SIM to authenticate itself to the network but also the network to authenticate itself to the SIM, significantly reducing the risk of man-in-the-middle attacks and unauthorized cloning.
Once the scan completes, the program displays the extracted and Ki . These can then be saved into a file, often in a .dat format, which can be used by smart card writing software to clone the data to a new multi-SIM card. Important Considerations and Limitations Woron Scan 1.09
The software cannot scan a SIM card through standard phone interfaces or modern USB adapters. It requires specialized hardware configurations:
Understanding the history of tools like Woron Scan 1.09 provides valuable insight into the iterative nature of cybersecurity, where the discovery of vulnerabilities leads directly to the development of more resilient global communication standards. Share public link

Version 1.08 reportedly had a rating of 7.23/10 based on 47 votes at the time, with 3,978 downloads recorded. The user interface and core functionality appear to have been similar to 1.09, with incremental improvements rather than a complete overhaul.
