FragAttacks to impact all modern security protocols of Wi-Fi

#fragattacks #wifi

As the world gets more connected, malicious users will find a way to get to the commoner. Wi-Fi's wavebands have relatively high absorption and work best for line-of-sight use. Many common obstructions such as walls, pillars, home appliances, etc. may greatly reduce range, but this also helps minimize interference between different networks in crowded environments. An access point (or hotspot) often has a range of about 20 metres (66 feet) indoors while some modern access points claim up to a 150-metre (490-foot) range outdoors. Newly Discovered WiFi Flaws that is FragAttacks stand for fragmentation and aggregation attacks, derive from the initial design of Wi-Fi protocols and several programming misconfigurations introduced to Wi-Fi devices.

These vulnerabilities surprise many due to the substantial improvements in WiFi security. For one, the defences against KRACK were proven entirely secure. This—coupled with the latest WPA3 security—which also went through improvements—made WiFI much safer than before. FragAttacks vulnerabilities are divided into two major categories: Design Flaws and Implementation Vulnerabilities. Design Flaws are flaws within the WiFi standard itself. These are found in most devices but are difficult to attack due to them requiring user interaction or unique network settings. Implementation vulnerabilities, however, are easier to attack. However, features that were not adopted into practice and parts of WiFi that were not widely studied earlier led to newly discovered design flaws and brought the security holes to be abused to proceed with sophisticated attacks, including those aimed at seizing control over outdated Windows 7 installations inside a local network.
