It is a very small application (usually under 1MB) that can run from a USB drive.
The software allows users to manage or, in some cases, attempt to recover PIN and PUK codes depending on the card's security level. Phonebook Management:
In the digital age, the demand for portable software—applications that run without installation, often from a USB drive—has grown significantly. Portable versions of antivirus, system scanners, and cleanup tools are especially appealing to IT professionals and privacy-conscious users. However, this demand has also created a fertile ground for malicious actors to distribute counterfeit or backdoored software. The hypothetical or misremembered “Woron Scan 109 Portable” serves as an excellent example of why users must exercise extreme caution when encountering unfamiliar portable security tools. woron scan 109 software portable
Woron Scan is a classic Windows-based application used primarily to extract cryptographic keys—specifically the and IMSI (International Mobile Subscriber Identity) —from older GSM SIM cards.

If testing older cards for cryptographic weaknesses, the reader must support a clock frequency of 3.571 MHz or 6.00 MHz. Software Configuration
Because the software is legacy and its primary use is technical, you will not find it on sites like the developer's official page or major download portals. Portable versions of antivirus, system scanners, and cleanup
: If scanning for KI, the software will perform a series of challenges and responses with the card to derive the 128-bit key. Security and Legal Considerations
The software works exclusively against SIM cards utilizing the legacy authentication algorithm. This algorithm suffered from a severe structural flaw known as a "differential power and collision attack." By sending a massive sequence of targeted challenges to the card and measuring the responses, Woron Scan can mathematically deduce the secret Ki value.
