That\u2019s why this bug is so cool and provides an opportunity to exploit devices literally with zero-click interaction at any state of wireless connection (even when a device isn\u2019t connected to any network). For example, one can do RCE in just powered-on Samsung Chromebook. So just to summarize:<\/p>\n

  1. It doesn\u2019t require any user interaction.<\/li>\n
  2. It can be triggered every 5 minutes in case of GNU\/Linux operating system.<\/li>\n
  3. It doesn\u2019t require the knowledge of a Wi-Fi network name or passphrase\/key.<\/li>\n
  4. It can be triggered even when a device isn\u2019t connected to any Wi-Fi network, just powered on.<\/li>\n<\/ol>\n<\/blockquote>\n

    In this research, I used ALFA networks wireless adapter in the monitor mode, which is based on Realtek 8187 wireless chipset. The exploit can be implemented with python Scapy<\/a> framework. For some reason, Ubuntu GNU\/Linux distrubution isn\u2019t good enough to inject Wi-Fi frames fast, so it is better to use Kali.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
