It concerns an authentication system which is widely used to secure wireless connections.
Experts said it could leave "the majority" of connections at risk until they are patched.
The researchers added the attack method was "exceptionally devastating" for Android 6.0 or above and Linux.
A Google spokesperson said: "We're aware of the issue, and we will be patching any affected devices in the coming weeks."
The US Computer Emergency Readiness Team (Cert) has issued a warning on the flaw.
"US-Cert has become aware of several key management vulnerabilities in the four-way handshake of wi-fi protected access II (WPA2) security protocol," it
said.
"Most or all correct implementations of the standard will be affected."
Computer security expert from the University of Surrey Prof Alan Woodward said: "This is a flaw in the
standard air max 97
gold uscita , so potentially there is a high risk to every single wi-fi
connection out there, corporate and domestic.
"The risk will depend on a number of factors including the time it takes to launch an attack and whether you need to be connected to the network to launch
one, but the paper suggests that an attack is relatively easy to launch.
"It will leave the majority of wi-fi connections at risk until vendors of routers can issue patches."
Industry body the Wi-Fi Alliance said that it was working with providers to issue software updates to patch the flaw.
"This issue can be resolved through straightforward software updates and the wi-fi industry air
max 97 gold uomo , including major platform providers, has already started
deploying patches to wi-fi users.
"Users can expect all their wi-fi devices, whether patched or unpatched nike air
max 97 bianche , to continue working well together."
It added that there was "no evidence" that the vulnerability had been exploited maliciously.
Tech giant Microsoft said that it had already released a security update.
Security handshake
The vulnerability was discovered by researchers led by Mathy Vanhoef, from Belgian university, KU Leuven.
According to his paper air max 97
bianche uomo , the issue centres around a system of random number
generation known as nonce (a number that can only be used once), which can in
fact be reused to allow an attacker to enter a network and snoop on the data
being sent in it.
"All protected wi-fi networks use the four-way handshake to generate a fresh session key and so far this 14-year-old handshake has remained free from
attacks, he writes in the paper describing Krack (key reinstallation attacks).
"Every wi-fi device is vulnerable to some variants of our attacks. Our attack is exceptionally devastating against Android 6.0: it forces the client into
using a predictable all-zero encryption key."
Dr Steven Murdoch from University College air max 97 nere
uomo , London said there were two mitigating factors to what he agreed was
a "huge vulnerability".
"The attacker has to be physically nearby and if there is encryption on the web browser, it is harder to exploit."
When any device uses wi-fi to connect to, say nike air max 97
nere , a router it does what is known as a "handshake": it goes through a
four-step dialogue, whereby the two devices agree a key to use to secure the
data being passed (a "session key").
This attack begins by tricking a victim into reinstalling the live key by replaying a modified version of the original handshake. In doing this a number
of important set-up values can be reset which can, for
example http://www.airmax97offerta.it/ ,
render certain elements of the encryption much weaker.
This attacks appears to work on all wi-fis tested - prior to the patches currently being issued.
In some it is possible to decrypt and inject data, enabling an attacker to hijack a connection. In others it is even worse as it is possible to forge a
connection, which nike air max 97
offerta , as the researchers note, is "catastrophic".
Not all routers will be affected but the people this could be most problematic for are the internet service providers who have millions of routers
in customers' homes. How will they make sure all of them are secure?

BEIJING, Feb. 28 (Xinhua) -- More than four years after promising a great renewal of the Chinese nation, while making sure China stands tall in the world
and the Communist Party of China (CPC) runs itself with strict discipline, Xi
Jinping's insights on China's political and economic development are
revitalizing China's modernization drive.
When Xi appeared in front of the press at the Great Hall of the People on Nov. 15, 2012 after being elected as the Party's top leader, his confident
demeanor and open admission of challenges such as the Party's corruption all
pointed to change.
"We are not complacent, and we will never rest on our laurels," he told the 1.3 billion Chinese in a televised address, after praising past achievements.
More than 1,500 days into his helmsmanship, Xi has successfully imbued the country's political and economic governance thought with his own thinking.
The Chinese president, who is also general secretary of the CPC Central Committee and chairman of the Central Military Commission, has spearheaded a
popular anti-graft drive which exposed a long list of fraudulent officials, from
low-ranking "flies" to high-ranking "tigers."
In 2016, a report by The Wall Street Journal said that during the campaign, which has punished more than a million officials since late 2012, Xi has called
for greater checks on political power, creating a "cage of regulations" that
ensures cadres "dare not, cannot and don't want" to be corrupt.
Xi has publicly defended free trade against the backdrop of weak growth momentum in major economies and rising trade protectionism, and managed to
sustain the world's second-largest economy on the track of fast
