Do We Still Need Subnets in Virtualized Networks?
The proponents of microsegmentation are quick to explain how the per-VM-NIC traffic filtering functionality replaces the traditional role of subnets as security zones, often concluding that “you can deploy as many tenants as you wish in a flat network, and use VM NIC firewall to isolate them.”

Presenter: Craig Williams (@security_craig) – Sr Technical Leader / Security Outreach Manager, Cisco TALOS
I’m from Talos. We love to stop bad guys.
Talos by the numbers:
- 1.1 million incoming malware samples per day
- 1.5 billion Sender Base reputation queries per day
Talos has a serious amount of data. For serious.
Data is key. It allows generation of real threat intel.
We basically have a bottomless pit of data
Talos vuln dev team:
- Looking for ways to programmatically find 0-days
- Takes this research and feeds it back into Cisco to a) make Cisco products more secure and b) generate sigs and threat intel to protect customers
With ransomware, you’re basically funding the malware underground.
Malvertizing:
- Malicious ads which redirect user to malware and then infects them
- Kyle & Stan campaign dynamically generated a new .exe every time it was downloaded; prevented matching on the file hash; Cisco AMP can stay on the bleeding edge of this
- blogs.cisco.com/security/talos/kyle-and-stan
Destructive/Wiper Malware:
- Targets your data
- Not just file data, but also seen targetting network devices and wiping their configs
- Cryptolocker 2.0: uses TOR for C&C; encrypted binary to avoid hash fingerprinting; anti-VM check
- Cryptolocker 3.0: still Continue reading

What’s the state of iPhone PIN guessing
I think even some experts have gotten this wrong, so I want to ask everyone: what's the current state-of-the-art for trying to crack Apple PIN codes?This is how I think it works currently (in iOS 8).
To start with, there is a special "crypto-chip" inside the iPhone that holds your secrets (like a TPM or ARM TrustZone). I think originally it was ARM's TrustZone, but now that Apple designs its own chips, that they've customized it. I think they needed to add stuff to make Touch ID work.
All the data (on the internal flash drive) is encrypted with a random AES key that nobody, not even the NSA, can crack. This random AES key is stored on the crypto-chip. Thus, if your phone is stolen, the robbers cannot steal the data from it -- as long as your phone is locked properly.
To unlock your phone, you type in a 4 digit passcode. This passcode gets sent to the crypto-chip, which verifies the code, then gives you the AES key needed to decrypt the flash drive. This is all invisible, of course, but that's what's going on underneath the scenes. Since the NSA can't crack the AES key Continue reading

PQ Show 51 – LightCyber Magna Active Breach Detection – Sponsored
LightCyber Magna Active Breach Detection automatically detects active attackers by identifying the anomalous operational behaviors sourced from compromised hosts in your network. By focusing on actual attack behaviors, and not technical artifacts like signatures, Magna provides accurate breach indicators and eliminates excessive false positives.

How to Enable Dot1x – more complex setup for wired network
How does Internet work - We know what is networking
This one is long. Do not be afraid though, I made it just to give you the fastest way to deploy functional dot1x to your company HQ without reading even more documentation and searching for those little timer default settings. I the article prior to this I showed you how to setup your environment with simple dot1x and make it as simple as possible. I will not repeat again the part about setting up Radius Clients on server side, everything else is here once again just more complex. Now is time for a more complex example that will make your implementation
How to Enable Dot1x authentication for wired clients
How does Internet work - We know what is networking
If your LAN is extending to some places where unauthorised people can just plug in and gain access to your protected network, it’s time to implement some security on your access switch. The best thing to do is to implement IEEE 802.1X port-based authentication which will enable users/machine authentication and prevent unauthorized devices from getting access switch port running when connected. IEEE 802.1X port-based authentication is mostly called simply as dot1x. In this article I will show you how to configure some basic dot1x stuff on switch side. I will also include Windows machine side of configuration as this is something most people presume
Why It’s So Hard To Find Intruders After A Network Penetration

Uh, the only reform of domestic surveillance is dismantling it
A lot of smart people are cheering the reforms of domestic surveillance in the USA "FREEDOM" Act. Examples include Timothy Lee, EFF, Julian Sanchez, and Amie Stepanovich. I don't understand why. Domestic surveillance is a violation of our rights. The only acceptable reform is getting rid of it. Anything less is the moral equivalent of forcing muggers to not wear ski masks -- it doesn't actually address the core problem (mugging, in this case).
Bulk collection still happens, and searches still happen. The only thing the act does is move ownership of the metadata databases from the NSA to the phone companies. In no way does the bill reform the idea that, on the pretext of terrorism, law enforcement can still rummage through the records, looking for everyone "two hops" away from a terrorist.
We all know the Patriot Act is used primarily to prosecute the War on Drugs rather than the War on Terror. I see nothing in FREEDOM act that reforms this. We all know the government cloaks its abuses under the secrecy of national security -- and while I see lots in the act that tries to make things more transparent, the act still Continue reading
Understanding TSA Math
At the end of every year, the TSA blogs about the weapons and explosives it prevented from getting on board airplanes. They are trying to brag about all the dangers they've stopped. But the opposite is true, when you do the math, you realize that they are stopping no dangers at all. The TSA stops less than half the bombs that get on board airplanes -- yet airplanes are not falling out of the sky due to the bombs that do get on board. Thus, mathematically, bombs aren't a danger. It therefore doesn't matter if the TSA stops bombs or not.
We know the TSA stops less than 50% of bad stuff from various sources. The first is the government's own tests, such as that described in a recent story where the TSA failed a shockingly 95% of the time.
Another is a statistic reported by the TSA where the number of firearms they stop every year is rapidly increasing. This does not match any other trend in society, such as the number of people carrying firearms. The only reason for such rapid growth is that the TSA gets better every year at detection. That means, historically, the TSA is Continue reading

Silk Road operator Ross Ulbricht was sentenced to life in prison without parole. Maybe this is a fair sentence for selling $200 million in illegal drugs. Or, since all the lawyers I talk to think it's excessive (worse than what even the prosecutors asked for), maybe it's within the normal range of excess in the War on Drugs. I'm not a lawyer, so I can't judge this.But, I'm interested in the comments the judge made justifying her hard sentence. According to Andy Greenberg at WIRED, the judge said:
“The stated purpose [of the Silk Road] was to be beyond the law. In the world you created over time, democracy didn’t exist. ... Silk Road’s birth and presence asserted that its…creator was better than the laws of this country. This is deeply troubling, terribly misguided, and very dangerous.”This is silly on the face of it. The stated purpose of all crime is to "be beyond the law". I mean, when I go above the speed limit in my BMW, my stated purpose is to go beyond the legal limit. I'm not sure I understand the logic here.
I'm being disingenuous, of course, because I do understand. What the Continue reading
