Woron Scan 1.09 – Limited

is a Windows-based software utility designed to interact with smart card readers to read, analyze, and sometimes extract security credentials from GSM SIM cards 1.2.1 . Its primary function is to extract crucial identification and cryptographic data—specifically the IMSI (International Mobile Subscriber Identity) and the Ki (Key Identification) —which are essential for cloning older, vulnerable SIM cards 4.2.2 . Key Capabilities and Features

While collision searching is a cryptographic attack, Woron Scan 1.09 also leveraged a form of side-channel analysis, specifically a timing attack or power analysis inference (depending on the hardware used). In the context of the software, the attack

In the early days of GSM mobile networks, SIM cards relied on relatively primitive cryptographic algorithms to authenticate mobile devices to cellular towers. The most common algorithm used at the time was Comp128v1.

While modern smartphones have made SIM card management largely invisible to the user, Woron Scan represents a fascinating era of "DIY" mobile security. Here is a deep dive into what Woron Scan 1.09 is, how it functioned, and its place in tech history. What is Woron Scan 1.09? Woron Scan 1.09

: It could only successfully clone older SIM cards (Version 1 of the COMP128 algorithm). Newer "V2" or "V3" cards introduced in the late 2000s were hardened against the specific brute-force and side-channel attacks Woron Scan employed.

If you are experimenting with legacy telecom hardware, keep these safety practices in mind:

Consequently, the industry transitioned away from the flawed COMP128v1 architecture: is a Windows-based software utility designed to interact

The version number 1.09 places the software in a perpetual “almost ready” state. Unlike today’s SaaS products with rolling updates, shareware of the 1990s and early 2000s often lingered in sub-2.0 versions for years. Each minor increment (1.07 → 1.08 → 1.09) signified bug fixes or support for new drive types (e.g., IDE, SCSI, or early SATA). The developer—possibly an individual named Woron or a team using the name as a brand—would distribute the tool via BBS (bulletin board systems), floppy disks in computer magazines, or early download sites like SimTel or Tucows.

Once the scan is successful, the software will display the 32-character Save this information (IMSI and Ki) to a

The phone sends the SRES back to the network; if it matches the network's calculation, access is granted.

Ask any veteran tech about Woron Scan 1.09, and they will mention the noise. When the software encounters a bad sector, it begins a rhythmic retry pattern involving the stepper motor. The sound is a distinctive "Click... whirrr... click... whirrr." If you run the repair function, the drive often emits a high-pitched "squeal" followed by a loud as the heads reset.

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.
