Computer scientists in Japan say they've developed a way to break the
WPA encryption system used in wireless routers in about one minute.
The attack gives hackers a way to read encrypted traffic sent between
computers and certain types of routers that use the WPA (Wi-Fi Protected
Access) encryption system. The attack was developed by Toshihiro
Ohigashi of Hiroshima University and Masakatu Morii of Kobe University,
who plan to discuss further details at a technical conference set for
Sept. 25 in Hiroshima.
Last November, security researchers first showed how WPA could be
broken, but the Japanese researchers have taken the attack to a new
level, according to Dragos Ruiu, organizer of the PacSec security
conference where the first WPA hack was demonstrated. "They took this
stuff which was fairly theoretical and they've made it much more
practical," he said.
They Japanese researchers discuss their attack in a paper presented at
the Joint Workshop on Information Security, held in Kaohsiung, Taiwan
earlier this month.
