nca noc engineer 2A protocol that secures Wi-Fi networks has a security flaw (called “KRACK”) that exposes most wireless networks to eavesdropping. KRACK is a flaw in the wireless protocol called WPA-2 which is in wide use. If this flaw is exploited, it would give an attacker free access to hijack connections, inject malicious content, and read data.

As of this writing, there isn’t any software in the wild that can exploit this flaw, but that can change quickly. Many vendors have released patches to this flaw already, please check your vendor’s website or call their support team to find out if one is available for your phones, computers, and network devices. Windows and Apple iOS are largely immune from this vulnerability; however, Android, Samsung, Cisco and others are not.


What you can do:

  • Check with your manufacturer for a patch and apply immediately if available
  • Do not use Wi-Fi for business-critical applications, or when accessing sensitive information
  • Use Encryption technologies such as VPN to secure wireless network traffic
