Wireless Presenters Attacked Using an Arduino

Posted by on 29/07/2010 No comments

An anonymous reader writes “This week Dutch security researcher Niels Teusink described a method of attacking wireless presenter devices at an Amsterdam security conference. He had a demo showing how it is possible to use an Arduino and Metasploit to get remote code execution by sending arbitrary keystrokes to the presenter dongle. He has now released the code and made a blog post explaining how it all works. Better watch out the next time you’re giving a presentation using one of these devices!”

German User Fined For Having an Open WI-Fi

Kilrah_il writes “A German citizen was sued for copyright infringement because copyrighted material was downloaded through his network while he was on vacation. Although the court did not find him guilty of copyright infringement, he was fined for not having password-protected his network: ‘Private users are obligated to check whether their wireless connection is adequately secured to the danger of unauthorized third parties abusing it to commit copyright violation,’ the court said.”

Wi-Fi Direct aims to be the ‘Bluetooth Killer’

Imagine a wireless home network where devices communicate directly with one another instead of through the wireless router — a sort of mesh network without the need to switch to ad hoc mode. Today the Wi-Fi Alliance announced it has almost completed the standard which could make these a reality: Wi-Fi Direct.

Wi-Fi Direct was known as “Wi-Fi Peer-to-Peer,” and has repeatedly been referred to in IEEE meetings as a possible “Bluetooth Killer.” By means of this standard, direct connections between computers, phones, cameras, printers, keyboards, and future classes of components are established over Wi-Fi instead of another wireless technology governed by a separate standard.

Even though the 2.4 GHz and 5 GHz bands are often dreadfully overcrowded in home networks, the appeal of such a standard is twofold: Any certified Wi-Fi Direct device will be able to communicate directly with any legacy Wi-Fi devices without the need for any new software on the legacy end, and transfer rates will be the same as infrastructure connections, thoroughly destroying Bluetooth. The theoretical maximum useful data transfer for Bluetooth 2.0 is 2.1 Mbps, while 802.11g has a theoretical maximum throughput of 54 Mbps.

“Wi-Fi Direct represents a leap forward for our industry. Wi-Fi users worldwide will benefit from a single-technology solution to transfer content and share applications quickly and easily among devices, even when a Wi-Fi access point isn’t available. The impact is that Wi-Fi will become even more pervasive and useful for consumers and across the enterprise,” Wi-Fi Alliance executive director Edgar Figueroa said in a statement today.
