Happy New Year!  No Resolutions Required
Posted by Lisa Garvey on Jan 3, 2018

For the past several days, I’ve been inundated with promotional emails telling me how to get the new year off to a good start: lose weight, exercise, get better sleep, clear out my closet, increase my credit rating. (And, since I live in California, I can’t even drive to the grocery store without passing a billboard promising that recreational weed will help me achieve all of the above. Frankly, I don’t think it can help with my credit score.)

The Not-So-Fast Times at Ridgemont High
Posted by Louise Peter on Dec 19, 2017

Many of us recall the scene from Fast Times at Ridgemont High when Jeff Spicoli, played by Sean Penn, gets the munchies and orders pizza to be delivered to Mr. Hand’s classroom. If this happened today, Spicoli would have ordered pizza from his iPhone without leaving his seat. And Spicoli’s phone? It would be connected to the school’s WiFi network. And with the growing number of student and school issued devices accessing the WiFi network, WiFi performance would be… well, less than Greased Lighting (but that’s for another blog).

Securing K-12 WiFi - A Scary Movie Blog
Posted by Louise Peter on Oct 31, 2017

It is a classic urban legend horror scene - a young woman is home alone (she is usually a babysitter). She receives creepy phone calls asking "Have you checked the kids?" The babysitter calls the police and the police set up watch outside the house to keep the babysitter safe. The police trace the phone calls and to their horror, they discover that the calls are not coming from another location, but they are coming from inside the house.

About One CVE at the Tail End of KRACK: 13088
Posted by Hemant Chaskar on Oct 27, 2017

In my last video blog on KRACK attack, I explained the technical details of workings and countermeasures for 9 out of 10 CVEs. The one I did not discuss in detail was CVE-2017-13088. At the time there wasn't enough information available on it and though it looked like the twin of CVE-2017-13087, due to differences between how group keys are distributed in MFP mode versus non-MFP mode, it required separate consideration.  After receiving more details from the researcher (@vanhoefm), I am prepared to share  information about CVE-2017-13088 and the appropriate countermeasures.

A+ WiFi on the Big Days and Every Day
Posted by Jeff Olson on Oct 24, 2017

Johnny is excited - well, not really - because tomorrow is state-wide, academic-testing day at his school. For weeks now, his teachers have told him just how important this day is for him and his school. Even his parents were instructed on how they can help prepare Johnny for the big day: ensure he gets enough sleep, has a quality breakfast, and arrives to school on-time. Johnny isn’t thrilled by this extra attention.

WPA2 Key Reinstallation Vulnerabilities (KRACK) Explained
Posted by Hemant Chaskar on Oct 16, 2017

Researchers from the University of Leuven (@vanhoefm and team) have discovered flaws in WPA2 implementation in clients and APs. These flaws create vulnerabilities for replay and decryption attacks on packets transferred over WiFi links. They have named them KRACKs (Key Reinstallation AttaCKs). Both 802.1x (EAP) and PSK (password) based networks are affected. These vulnerabilities have been cataloged under 10 CVEs. In the series of videos below, I explain these CVEs in detail with Vivek Ramachandran, Founder and CEO of Pentester Academy.

Is your Business Wireless Network Secure?
Posted by Jeff Olson on Oct 10, 2017

We’ve Got Your Back.

Security is top of mind for IT teams, business leaders, and the general public. News of attacks, ransomware, and data breaches has become commonplace; most recently Equifax and Yahoo. Have you stopped to ask yourself: Is my WLAN secure? Have I done all that I can to ensure is it secure?

Witnessing ethical train wreck after train wreck in Silicon Valley, it’s easy to conclude that the quest for success at all costs is a recent phenomenon and one limited to startups.

Auto Packet Capture, Where Have You Been All My Life?
Posted by Robert Ferruolo (Dr. RF) on Aug 8, 2017

You can tell how long someone has been troubleshooting networks by the length of their arms. Orangutans like me have been doing it a long, long time.  I started with a sewing machine sized Network General luggable that I carried around the world. Now I have to stand up very straight  to keep my knuckles from dragging on the ground.
