Nabaztag (Armenian for "hare", նապաստակ (napastak)) is a Wi-Fi enabled ambient electronic device in the shape of a rabbit, invented by Rafi Haladjian and Olivier Mével, and manufactured by the company Violet.

[1] Nabaztag was designed to be a "smart object" comparable to those manufactured by Ambient Devices; it can connect to the Internet (to download weather forecasts, read its owner's email, etc.).

[11] At first speaking only in English and French, as of June 2007, Nabaztag fully supports services in German, Italian, Spanish and Dutch.

Individual RFID chips were also produced and were called ztamp:s.[12] Nabaztag owners can join social networks to share photos and videos on websites like Flickr and YouTube.

Since Nabaztags can be programmed to provide new services using the API, there are user-created applications available, including a Dashboard widget and a lottery alarm.

[citation needed] In December 2006 (most notably around Christmas) a number of sold rabbits caused issues for Violet, the maker of Nabaztag.

[citation needed] The device embeds a PIC18F6525 microcontroller, a BenQ PC card 802.11b Wi-Fi adapter, an ml2870a Audio-PCM sound generator, an ADPCM converter, two motors to activate the ears, a TLC5922 LED controller, and a small amount of memory.

Nabaztag/tag can, as of November 2007, use RFID tags to read special edition versions of children's books by the French publisher Gallimard Jeunesse.

The Wi-Fi was also upgraded to support WPA encryption, and now uses a cheaper SoftMAC card instead of the BenQ device which embedded its own 802.11 protocol stack.

Additionally, it includes an integrated web cam, a USB port (which can be used for power as well as connectivity), and 256 MB of onboard storage.

New products make a stronger match to market needs, marking the end of Karotz's great story."

During DEF CON 21, Daniel Crowley, Jennifer Savage and David Bryan pointed out several security vulnerabilities[20] about the Karotz.
