The Wi-Fi Protected Access (WPA) encryption standard for wireless networks has been cracked by two security experts, Erik Tews and Martin Beck.
They will present their approach at the PacSec conference in Tokyo next week and discuss it with attendees. With this attack, a hacker can connect to any computer on the same router and send or read data to it.
According to Martin Beck, the method they discovered was based on a vulnerability in the Temporal Key Integrity Protocol (TKIP) in the WPA standard, and was able to solve it in just 15 minutes, the shortest time ever recorded for such an act.
In fact, TKIP had already been guessed by someone using a dictionary attack before this, which is not a real "crack". Instead of this approach, the two security experts used a way to get WPA routers to send large numbers of data packets, and then build some kind of mathematical model through these packets, so that the password can be quickly cracked.
For now, only the WPA2 wireless standard appears to be relatively secure. WEP has long been a high-profile breach, from time to time exposed some weaknesses. At present, WPA has been widely used in many enterprises or homes, and its cracking has exposed countless wireless routers in homes and businesses to danger. For a long time, countless security experts have been working on the security of wireless networks. It is believed that in the near future, there will be more secure security solutions than WPA or even WPA2.
