  • There has been a new attack on WPA
  • You no longer need to have quality of service support
  • With the new attack though the user you are attacking and the access point can not be within radio range of each other
  • The hacker has to be the link between the access point and the user
  • They use the fact that they have preemptive access to the traffic in order to perform the exploit
  • You still do not get the WPA key you are only able to modify the ARP packet
  • The other end is also blacked out whilst you are decrypting the packet
  • Steve's advise is to just use WPA AES

  • Current 3D technology in cinemas works using "circular" polarization the way it works is
  • There's a digital projector with a special thing in front of it which at 144 times per second is flipping back and forth the circular polarization between clockwise and counterclockwise at the same time that the image is being changed.
  • So this light goes down and hits the silvered screen
  • They scramble the polarization upon reflection
  • Then what comes back to the user is the two separate images, circularly polarized with different spins
  • And they're wearing glasses with the matching circular polarized filters.
  • The advantage of this method over older technology is you do not have to hold your head straight

Questions & Answers

01:02:48 - 01:58:49

Question: [ 01 ]

01:02:48 - 01:11:10 Craig (Chicago)
Question: Is Hot Spot Shield a secure VPN service?

Answer: They are advertising supported so they are tracking and monitoring everything you do whilst using their service. This is a privacy risk and means someone is messing with your connection to insert adds. Steve does not give this his approval but recommends Hot Spot VPN

Question: [ 02 ]

01:11:11 - 01:17:38 Bob Carneim (Oak Ridge, Tennessee)
Question: What comes after flash cookies as a method of tracking people over the internet?

Question: [ 03 ]

01:17:39 - 01:25:20 Bill Barnes (Charlotte, North Carolina)
Question: Is opening ports through my firewall a security risk ?

Answer: If you open a port through your firewall then everyone on the internet has access to the service you have allowed. If a vulnerability is found in the service hackers may be able to get access to your network.

Comment: [ 04 ]

01:25:21 - 01:28:25 Joe Dorward (Bracknell Forest, England)
Listener Comment: If you know people who wont use a secure password mangement solution then it is better to write down a really good password than memorise a poor one as someone is more likely to try and guess your password over the internet than come to your house and look at it.

Steve's Comment: Steve agrees but adds that you should make an adjustment to the password you write down when you type it in so even if someone gets access to the paper with the password written on they cant use it.

Comment: [ 05 ]

01:28:26 - 01:40:33 Paul Bye (Rochester, Minnesota)
Listener Comment: My ISP "Charter Communications" are intercepting name errors which is a fundamental change to how DNS is meant to work and now means my VPN wont work.

Steve's Comment: There is normally a way to opt out of this 'feature' and DNS Benchmark contains of list of publicly available name servers which you could switch to

Question: [ 06 ]

01:40:34 - 01:48:48 Rod Duckworth (Sydney, Australia)
Question: Why cant I download all previous episodes through iTunes and also can I put the audio files on my site?

Answer: Leo only puts the 20 most recent shows on the RSS feeds for iTunes to save bandwith. You can put the audio files on your site but Steve and Leo would prefer it if you just used their URL as it enables podtrac to count how many times the episode was downloaded and then the sponsors can pay them.

Comment: [ 07 ]

01:48:49 - 01:52:15 John Prince (Somerset, UK)
Listener Comment: My router doesn't support WPA 2 so I contacted netgear about getting a firmware update and they told me that it is an end of life product and I would need to buy a new router.

Steve's Comment: Companies do have to discontinue products at some point but you could get a router that you can put open source firmware on

Question: Could a hacker capture encrypted packets and save them for decryption in the future when computing power is greater ?
