Security flaw prompts fears on Wi-Fi connections..affects practically every single person in the world

A NEWLY discovered flaw in the widely used Wi-Fi encryption protocol could leave millions of users vulnerable to attacks, prompting warnings Monday from the US government and security researchers worldwide.

The US government’s Computer Emergency Response Team (CERT) issued a security bulletin saying the flaw can open the door to hackers seeking to eavesdrop on or hijack devices using wireless networks.

“Exploitation of these vulnerabilities could allow an attacker to take control of an affected system,” said CERT, which is part of the US Department of Homeland Security.

The agency’s warning came on the heels of research by computer scientists at the Belgian university KU Leuven, who dubbed the flaw KRACK, for Key Reinstallation Attack.

According to the news site Ars Technica, the discovery was a closely guarded secret for weeks to allow Wi-Fi systems to develop security patches.

Attackers can exploit the flaw in WPA2 — the name for the encryption protocol — “to read information that was previously assumed to be safely encrypted,” said a blog post by KU Leuven researcher Mathy Vanhoef.

“This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks.” The researcher said the flaw may also allow an attacker “to inject ransomware or other malware into websites.” The KRACK vulnerability allows attackers to circumvent the “key” on a Wi-Fi connection that keeps data private.

The Belgian researchers said in a paper that devices on all operating systems may be vulnerable to KRACK, including 41 per cent of Android devices.

The newly discovered flaw was serious because of the ubiquity of Wi-Fi and the difficulty in patching millions of wireless systems, according to researchers.

“Wow. Everyone needs to be afraid,” said Rob Graham of Errata Security in a blog post.

“It means in practice, attackers can decrypt a lot of Wi-Fi traffic, with varying levels of difficulty depending on your precise network set up.”

the elephant in the room..of course it can be hacked..this was shown years ago..

krack eh?

“According to the news site Ars Technica, the discovery was a closely guarded secret for weeks to allow Wi-Fi systems to develop security patches.”

yeah right..

  1. IMHO, only fools use wifi. 2.4GHz microwaves are used in microwave ovens. Don’t be stupid.

  2. Reblogged this on World Peace Forum.
