iCS Decoder for iCLASS® SE / SEOS Decoder

Introduction

Lab401 is the exclusive distributor for the iCopy-X in Europe and Oceania.

The iCS Decoder is an iCopy-X accessory that allows for the rapid decoding and cloning of iCLASS SE® / SEOS® Decoder.

Until now, cloning of iCLASS SE® and iCLASS SEOS® has been impossible. With the iCS Decoder and iCopy-X - it's as easy as cloning any standard RFID tag.

Most iCLASS® SE® & SEOS® systems still have legacy card acceptance enabled in their configuration. The iCS Decoder can decode iCLASS SEOS® IP / SE cards, and then generate an new card with legacy encoding.

For pentesters, the iCS Decoder exposes an entirely new in-scope attack surface. Likewise, LEA can use the device to make rapid clones in the field of a previously impossible badge type.

Please note:

• The iCS Decoder will only work for target systems that are configured to accept legacy cards. This is the default configuration.
• This technique will not work on all iCLASS SE® readers. Coverage is approximate 85%.
• The iCS Decoder is an accessory - it requires an iCopy-X.
