"I met you yesterday at SANS and was wondering if you could help me promote my mentor session of SEC508 starting on September 23rd. If you could forward this invitation onto your network of contacts, that would be awesome." - Evan

Listener Feedback: Listener Scott Is Evil

"Sorry if you spoke about this, but I'm still catching up on your shows. I'm not an expert on how the browser and SSL works, but I worry about this being true. Also, if this works, I'm a little hesitant to mention this because it could be used. I was wondering about using the DNS vulnerability to hijack domains. I hear a lot of people saying people can't hijack SSL secured domain because the certificate wouldn't validate. Well I can see that you can't spoof the root certificate authorities because the certificates are preloaded in the browser. However, can someone get a certificate able to issue other certificates from a trusted root certificate authority and then sign the phony paypal.com web page with it. This way when my browser goes to the phony paypal.com website, it will tell my browser it was signed by "evilCA.com", then my browser should check to see if "evilCA.com" is valid, and it would pass because it was signed by a root CA. So by browser should be happy and not even alert me anything is wrong and give me an SSL pad lock, maybe even an extended certificate, if you can issue those from a normal cert (because I doubt bad people would front a business for an EV cert). Is this how the browser chain of trust works? What did I miss to prevent people from doing this? Thanks and I promise to catch up on all the past shows. Scott"

Stories Of Interest

Hacking Biometric Locks

VMware Releases A TON of Patches - [PaulDotCom] - Patches still pending for VM Fusion, WTF! You should patch, its important, especially because the security of multiple machines is at risk, in a platform independent kind of way.

Chrome is Shiny, but scratches easily - [PaulDotCom] - Oh hey look, a new web browser! And look, vulnerabilities in the new web browser! Who would have thought? All software has vulnerabilities, especially new software. People have been hacking away at Firefox for quite some time, and they do a decent job of keeping things patched. Sure, they implement new features, which then could present software vulnerabilities, but they get fixed in a timely manner, a manner which best fits with my security requirements, so I am sticking with Firefox. Lets not even talk about IE, a browser still plagued with security flaws, and ones that don't get fixed until MS decides to bless us with their holy than thou bi-monthly patches.

"Securing" Your iPhone - [PaulDotCom] - I was excited about this article, until I read it. The first two items are implementing a 4 digit pass code, because that provides security, right. Then make sure your phone locks, well duh. And somehow re-mapping my home button protects my information, at least it prevents people from bypassing the lock and accessing my address book. Is that really security or just a workaround? The best part about the article? The screenshot of the iPhone shows they have 3 apps that need updating, doesn't keeping your software up-to-date apply to your phone as well? Also, none of this protects your information as it flys in clear text over open wireless networks...

Mythbusters Prevented From Running RFID Hacking Show - [PaulDotCom] - Conflicting stories abound, it appears that CC companies do not want RFID shortcomings to be public knowledge. I don't think that talking about RFID hacking and vulnerabilities is a crime, so look for some things coming soon.

HP Adds Smart Card Readers to HP Printers - [PaulDotCom] - Okay, here's a newsflash, authentication is not the major security problem on printers and multi-function devices!!!!! How about implementing software without vulnerabilities, using secure protocols to transfer data, hardening the operating system, and encrypting the files/filesystem? Now you have no excuse, if you are building on technologies such as smart cards to these devices, you can implement all of the other security measures.

Botnet Counts: For Good Measure - [PaulDotCom] - Some really cool graphs on the number of botnet drones, yes they have sharply increased over the past few months. However, even more frightening, the number of C&C servers increased (Reference). This means, more drones and more individual botnets, confirming suspiciouns that botnets are more abundant and perhaps purpose built to avoid detection and eventual shutdown.
