A vulnerability in the 802.11n wireless networking standard can be exploited by a remote attacker to target wireless networks, researchers have warned.

Introduced in 2009, the 802.11n standard is designed to increase the speed of wireless networks, improve their reliability and security, and extend the range of wireless transmissions. This version introduces a frame aggregation mechanism to the media access control (MAC) layer that increases throughput by sending two or more data frames in a single transmission.
