Wifi security is threatened by a new bug: reveals a Belgian researcher who has found the problem on several testing devices at his laboratory. Specifically it is the so-called fragattacks (fragmentation and aggregation attacks), which can exploit these vulnerabilities to attack the devices present within the radius of the radio range by stealing the information stored there. Experiments indicate that each wifi product is affected by at least one vulnerability, and that many products are affected by different vulnerabilities.
However, it is worth remembering to update your devices to the latest versions of the firmware and rely only on websites with https protocol. For further information we leave you to the original document that you can find linked to source.
