Woron Scan 1.09: A Lightweight but Outdated Port Scanner You Should Know About

: A compatible SIM card reader, often a Phoenix-style or Smart Card reader. Connectivity

When the GSM standard was originally established, network operators deployed the COMP128 algorithm to handle authentication and session key generation. The process relies on a challenge-response mechanism:

The “1.09” designation refers to a specific stable release from the classic family of Woron scanners, which also included versions like 1.07, 1.08, and the later 1.10 beta. Version 1.09 is often considered the most balanced release—bug-free, reliable, and compatible with Windows operating systems from Windows 98 up to Windows 10 (with some compatibility considerations).

According to multiple GSM forum discussions, Woron Scan is frequently mentioned alongside similar tools like SimScan, SIM-EMU, and GSM SIM Utility. It has been used by hobbyists, security researchers, and telecommunications enthusiasts to explore the capabilities and vulnerabilities of SIM cards, particularly older cards based on the COMP128v1 algorithm.

Several other applications serve overlapping functions or have superseded Woron Scan:

: The tool was famously used to attempt the extraction of the KI (Authentication Key) and IMSI (International Mobile Subscriber Identity) from older GSM SIM cards.

COMP128v1 was designed to keep the 128-bit Ki secret key hidden. When a tower challenged a phone, the SIM used the Ki key to generate a response. However, COMP128v1 suffered from a severe structural flaw: it leaked narrow bands of information when hit with specific, repetitive challenges.

Recognizing the massive vulnerability exposed by tools like Woron Scan, telecommunications operators rapidly phased out COMP128v1. They replaced it with algorithms (used in modern 3G, 4G LTE, and 5G SIM cards). These updated algorithms completely patched the side-channel info leaks. If you attempt to scan a modern SIM card with Woron Scan 1.09, the program will run infinitely without ever locating the Ki key. The "Self-Destruct" Counter Measures Woron Scan 1

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.

: It allows users to read, edit, and manage phonebooks or SMS messages stored directly on the card. Basic Setup Requirements

Woron Scan served as undeniable proof to major telecom giants that first-generation security standards were deeply flawed. The ease with which the tool ran on basic home hardware forced the industry to abandon early protocols and transition toward significantly more robust modern cryptographic layers. Why It Doesn't Work on Modern SIM Cards

This article provides a comprehensive overview of Woron Scan 1.09, covering its main functions, version history, usage scenarios, technical specifications, and important considerations for those interested in this niche software utility. Version 1

Despite its diminutive size, Woron Scan 1.09 packs a surprising set of features:

By scanning from inside the network, admins can verify firewall rules—ensuring that only intended ports are open.

is a legacy utility for reading and backing up GSM SIM card data. It excels at reading the phonebook, SMS, and technical identifiers (IMSI/ICCID) from older SIM cards. While it was historically significant for SIM analysis and cloning experiments, its utility is limited to 2G technology and is now mostly used by hobbyists or for retrieving data from legacy SIM cards.

Compared to other command-line cracking tools of its era, Woron Scan 1.09 gained massive traction due to its accessible graphical user interface (GUI) and robustness. Prominent features included:
