Wi-Fi WPA Security Found Vulnerable
Sean Michael Koerner | 10/19/2017
Researchers have found that the widely used Wi - Fi security protocol WPA 2 is vulnerable to a replay attack , leaving hundreds of millions of devices vulnerable.
The widely used Wi-Fi security protocol WPA2 is vulnerable to multiple vulnerabilities, collectively known as “KRACK attacks.” “Attackers can use this new attack method to read information that was previously thought to be securely encrypted,” the vulnerability advisory warns. “The attack is effective against all modern secure Wi-Fi networks.”
KRACK is an acronym for Key Reinstallation Attacks. The latvia mobile database discovered by security researchers Mathy Vanhoef and Frank Piessens of the Catholic University of Leuven in Belgium. The researchers detailed the KRACK attacks in a paper and plan to discuss them at the Computer and Communications Security (CCS) and Black Hat Europe conferences later this year.
In total, KRACK attacks exploit 10 vulnerabilities: CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081, CVE-2017-13082, CVE-2017-13084, CVE-2017-13086, CVE-2017-13087, and CVE-2017-13088. These are designations for different variants of key reinstallation attacks affecting WPA2.
The KRACK vulnerabilities introduce new approaches to exploiting the way WPA2 generates encryption keys for each session. The researchers note that all WPA2-protected Wi-Fi networks use a four-way handshake to generate a new session key.
"This 14-year-old handshake has not been attacked to date and is even proven secure," the paper's abstract states. "However, we show that the quadruple initial packet exchange is vulnerable to a key reinstallation attack."
