Wi-Fi technology depends on the ability to break big data into smaller data clusters. Depending on the network requirements the data constantly shifts from larger to smaller data packets. Researcher Mathy Vanhoef published a study last week which explains what he calls FragAttacks. A hacker within radio range can exploit a dozen vulnerabilities with the potential to impact huge numbers of wi-fi-enabled devices.
Vanhoef documents how hackers can redirect users to malicious websites. They may also exploit or tamper with network-connected devices. In FragAttacks, short for fragmentation and aggregation attacks, hackers inject malicious commands into encrypted Wi-Fi traffic. WPA-based encryption protection has serious vulnerabilities.
Trusted networks open to FragAttacks
With these types of hacks data in the form of malicious coding can be injected into the Wi-Fi traffic. But it’s not possible to exfiltrate and pull anything out. In other words, FragAttacks don’t let the hacker read users’ passwords or other private data.
