WIFI scramblers portable device
Recently, researchers have found a very big loophole in the WIFI protocol. 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 percent of Android devices. The vulnerability issue also sent shock waves across techno-savvy Japan, where a plethora of devices are connected wirelessly. A network without a password, just an agreement screen is even more insecure because now even people in the parking lot or building across the way can be sharing your digital connection! There are three solutions to help stay safe and secure in this digital wild west: stay offline, use your own access point or utilize a private network encryption system known as a VPN or use a WIFI jammer. The WIFI jamming device is the application of the signal transmission principle to isolate the WIFI signal, so that your smart device can not connect to the insecure wireless network.
