  PUBLIC DEFENDER

  

  By Brian Livingston

  International standards bodies are just months away from finalizing a wireless networking improvement that’s being called Wi-Fi 7. When devices start supporting and using the new protocol, Wi-Fi 7 promises theoretical speeds far beyond what’s currently possible with Wi-Fi 6 (which was officially approved back in 2014).

  But don’t go out and buy all new stuff just yet. Theory is one thing, and reality is another. You may never see noticeably faster speeds from any Wi-Fi 7 devices you may own in the future. What are the reasons for this? I’m glad you asked.

  ON SECURITY

  

  By Susan Bradley

  The last time I was called upon to perform my fundamental American civic duty was years ago. It hasn’t changed much, except for technology.

  There were bar codes, large displays that broadcast PowerPoint slides, and a YouTube video that explained jury service. That video went so far as to explain who sat where in the courtroom. (I thought that was obvious, but apparently I have watched way too many Perry Mason episodes.)

• Why Wi-Fi 6, aka 802.11ax, for wireless?

  HARDWARE

  

  By Ben Myers

  Now that there is broad availability of routers compatible with the new Wi-Fi 6 standard, it’s easy to ask, “What’s in it for me?”

  There is a myriad of devices that are compatible with the 802.11ac specification, from laptops to cell phones to tablets to Internet of Things (IoT) devices. But the 802.11ac spec is not without limitations.

  FragAttacks is a newly discovered set of vulnerabilities that, when exploited, allows an adversary to steal data by intercepting a network.

  For once, a threat may be less dangerous than advertised.

• Is Wi-Fi security irretrievably broken?

  Posted on October 15, 2017 at 19:45 CDT by woody • Comment in the Forums

  There’s a lot of buzz this weekend about a flaw that’s purported to break security on most Wi-Fi connections, allowing an eavesdropper to snoop or use the connection without permission.

  Said to involve CVE-2017-13077, 13078, 13079, 13080, 13081, 13082, 13084, 13086, 13087, 13088, when they’re posted.

  See this thread from @campuscodi and be watching Bleepingcomputer tomorrow for details.

• ELSA: How the CIA tracked the location of an infected PC using WiFi signals

  Posted on June 28, 2017 at 08:28 CDT by woody • Comment in the Forums

  The latest WikiLeaks release talks about ELSA, reportedly a CIA project that allowed the government (and now, apparently, everybody) to snoop on the location of an infected PC.

  ELSA is a geo-location malware for WiFi-enabled devices like laptops running the Micorosoft Windows operating system. Once persistently installed on a target machine using separate CIA exploits, the malware scans visible WiFi access points and records the ESS identifier, MAC address and signal strength at regular intervals. To perform the data collection the target machine does not have to be online or connected to an access point; it only needs to be running with an enabled WiFi device. If it is connected to the internet, the malware automatically tries to use public geo-location databases from Google or Microsoft to resolve the position of the device and stores the longitude and latitude data along with the timestamp.

  Clever.
