IPv6 Compromise Smartphones Users’ Privacy

IPv6Now that the IPv4 address pool is depleted and the IPocalypse is at hand, wrinkles are emerging in IPv6.  One of the wrinkles is with mobile devices. Most of the cool mobiles devices have been able to handle IPv6 for a while. Apple’s (AAPL) iPhones, iPads and iPods have been capable of handling IPv6 Since version 4 of the iOS operating system and most Google (GOOG) Android devices have been capable since version 2.1. H  Security is reporting that these mobile operating systems send information about their users to the network.

A device on an IPv6 network usually determines half of theirSmartphone risks address (the “interface identifier”) themselves, but H Security says that smartphones are sloppy with this task. According to the article, the smartphones simply add the same two bytes to their globally unique MAC address and use it as their identifier. As a result, they transfer a unique hardware ID whenever they communicate with an IPv6-enabled server.

The basic problem isn’t an IPv6 issue because there are other methods for generating the address. The article says that a device can generate a random interface identifier and replace it on a regular basis. This is called Privacy Extensions method and is the factory-set option in Windows; it can also be enabled in other operating systems. The article points out that devices running Apple’s iOS or Android offer neither the option to enable Privacy Extensions nor the option to disable IPv6, anyone who uses an affected device on an IPv6-enabled wireless network will send their ID.

IPocalypseThe only thing the smartphones are lacking is a control option in the user interface, as the Privacy Extensions do come as part of their kernel. For instance, on a (jailbroken) iOS 4 device with root access, they can be enabled with the same command that enables them on a desktop device running Mac OS X:

sysctl -w net.inet6.ip6.use_tempaddr=1

The blog claims the problem is only affecting a small number of users because IPv6 is not yet in widespread use. However, more ISPs plan to offer IPv6 in addition to the old IPv4 in the future. In addition, there are routers like the Cisco (CSCO) Linksys E3000, which will, automatically set up an IPv6 connection via a 6to4 conversion when their internet access is purely IPv4.

The author concludes that the issue is particularly sensitive because such devices tend to be used by one specific person. As a result, the MAC address, which is accessible to any server operator and network monitor, allows this user to be identified.

Help – My Thermostat is Calling Home to China!

U.S. Chamber of Commerce thermostat was communicating with an Internet address in ChinaPhil Neray of Q1 Labs, an IBM (IBM) company posted that in the recent Chinese hack of the U.S. Chamber of Commerce’s network, one attack vector was a thermostat. The thermostat at a Chamber town house on Capitol Hill which was communicating with an Internet address in China and a printer spontaneously started printing pages with Chinese characters (rb- I wrote about securing printers here).

The blog says the fact that the hackers were in the network for more than a year before being detected is not unusual. Mr. Neray cites the 2011 Data Breach Investigations Report, more than 60% of breaches remain undiscovered for a period of months or longer (versus days or weeks).

This is one of the risks of the Internet of Things. Security is in the era of IoT will have to use machines to monitor the machines.

CIA Chief: We’ll Spy on You Through Your Dishwasher

Dishwasher Spencer Ackerman at Wired points out that more personal and household devices are connecting to the internet, forming the Internet of Things and U.S.CIA Director General David Petraeus cannot wait to spy on you through them.

General Petraeus recently spoke about the “Internet of Things” at a summit for In-Q-Tel, the CIA’s venture capital firm. “‘Transformational’ is an overused word, but I do believe it properly applies to these technologies particularly to their effect on clandestine tradecraft” the blog recounts.

Mr. Ackerman predicts that people will be sending tagged, geolocated data that a spy agency can intercept in real-time when they open their Sears (SHLD) Craftsman garage door with an app on an Apple (AAPL) iPhone. “Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters — all connected to the next-generation internet using abundant, low-cost, and high-power computing,” Petraeus said, “the latter now going to cloud computing, in many areas greater and greater supercomputing, and, ultimately, heading to quantum computing.”

Wired says the CIA has a lot of legal restrictions against spying on American citizens. But collecting ambient geolocation data from devices is a grayer area, especially after the 2008 carve-outs to the Foreign Intelligence Surveillance Act. Hardware manufacturers, it turns out, store a trove of geolocation data; and some legislators have grown alarmed at how easy it is for the government to track you through your Apple iPhone or Sony (SNE) PlayStation.

The implications of the “Internet of Things” is profound when linked the transformational nature of the interconnected home network. The CIA sees great opportunity in wired home devices. Any home gadget with RFID, sensor networks, embedded servers, or energy harvesters is ripe for interception by spy agencies.

Koubachi Wi-Fi Plant Sensor Gives Your Plant a Voice

Internet of Things give potter plants a vpoiceKoubachi, the Swiss start-up company behind the popular iPhone plant care assistant presented its newest innovation at CeBIT 2012 in Hannover: the Koubachi Wi-Fi Plant Sensor according to ITnewsLink.

Building on the success of its popular interactive plant care assistant, Koubachi launched a Wi-Fi Plant Sensor that integrates into the Koubachi system to literally gives your plant a voice.

The Wi-Fi Plant Sensor measures soil moisture, light intensity and temperature. Using Wi-Fi, the data is sent to the Koubachi cloud, where it is analyzed by the Koubachi Plant Care Engine. The plant owner gets a detailed care instructions on watering, fertilizing, misting, temperature and light through push notifications or email. “The Koubachi Wi-Fi Plant Sensor is the first device ever that enables real-time monitoring of the plant’s vitality” says Philipp Bolliger, CEO of Koubachi, “It’s a truly unique product in the field of “Internet of Things” and bringing state-of-the-art technology to plant care.”

Smart Gadgets are Like Sleeper Cells in Your Kitchen

DTE Smart meterManufacturers are “future-proofing” their appliances with “Internet of Things” capabilities that are latent for now. Christopher Mims at MIT’s Technology Review asserts that major appliances bought in the last three years probably contain a Zigbee capable wireless radio that can send out information about a device’s status and energy use and receive commands that alter its behavior.

Many appliance makers don’t announce these capabilities, Mike Beyerle, an engineer at GE (GE) whom Mr. Mims interviewed about GE‘s Nucleus home energy management system. “We want to build up a base before we make a big deal out of it,” says Mr. Beyerle.

The author says that manufacturers aren’t telling consumers what their devices are capable of because, in part, those abilities are useless without an energy management hub like GE’s Nucleus or a utility company‘s smart meter. In both cases, smart appliances must be “bound” to a hub to communicate with the outside world.

Once a device is hooked up to an energy management system and become part of the IoT, it get interesting. Mr. Mims says that users who signed up for a “demand response” program with their utility to get a lower bill, enable the utility to control their appliances. For example a refrigerator’s ice maker’s defrost cycle or the elements in a clothes dryer can be manipulated to drive down power use during times of peak demand.

Most people do not realize that installing a new smart meter can activate a technological sleeper cell in their HDTV, kitchen or laundry room. All of these “smart” devices will be part of the “Internet of Things.” They will have an IP address (probably an IPv6 address) and will be broadcast via a Zigbee wireless network. This is why the CIA says it can spy on people through their dishwasher.

Connected Kitchen

Rosie the Robot Engadget says the Samsung RF3289 fridge is designed to let users access Pandora or tweet while grabbing a snack. Samsung touts it as the first to feature integrated WiFi. The Wi-Fi also offers the ability to view Google calendars, check the weather, download recipes from Epicurious, or leave digital notes

Engadet also reports LG’s Thinq line of connected appliances includes vacuum, oven, refrigerator, and washer / dryer. They support Wi-Fi and ZigBee to communicate with each other, the smart meter, smartphones and tablets.  That’s a pretty strong foundation to build the Internet of Things especially if the home is already equipped with ZigBee devices. CNET says the line can be troubleshot remotely; tech support can log in to the device see what’s wrong and fix it. Kenmore has a similar product line.

Flip the Switch on IPv6

World IPv6 launchWorld IPv6 day (Which I reported on here) took place in June 2011. Google (GOOG), Facebook, Yahoo (YHOO) and Akamai (AKAM) were among the participants in last year’s dress rehearsal. apparently everything went well last June.

Internet SocietyNathan Ingraham at The Verge recently noted that IPv6 is now ready for prime-time. The Internet Society announced that the IPv6 switch will be permanently flipped on June 6th, 2012.

The article says a number of major ISPs, networking hardware manufacturers, and web companies pledged support from day one. For starters, four of the biggest web properties will all enable IPv6 permanently:

Cisco SystemsFrom a hardware perspective, Cisco (CSCO) and D-Link (DLINK) both committed to enabling IPv6 across their range of home products by June.

GigaOM reports that Akamai (AKAM) and Limelight (LLWN) will also recruit other websites to join the initiative, by implementing IPv6 throughout their content delivery networks.

Internet Service ProviderSeveral leading ISP’s will enable IPv6 to enough of their customer base that at least one percent of their residential subscribers who visit IPv6 enabled websites;

Packet Pushers Podcast

Now that Spring has magically erupted here and I no longer have to white-knuckle my daily commute thru ice and snow and rain sometimes in the same drive, I can starting listening to the Packet Pushers Podcast’s again. The podcasts help me keep my tech info up to date as I get more deeply involved in the business side of IT. It is also good to hear global opinions on tech.

Packet Pushers Podcast

On the podcast, they talk about routing, switching, security, firewalls, data center, and industry trends in a round table format. According to the web site, topics can be “deep dived” where they focus on practical technology issues, or they sometimes review the latest announcements from vendors and discuss the technologies.

Brocade Selling Itself

network ChannelInsider citing the Wall Street Journal is  reporting that network equipment maker Brocade Communications Systems Inc. put itself up for sale on 10-05-09. The paper, citing people familiar with the matter, said Oracle Corp and Hewlett-Packard Co were potential bidders for the company, but a deal was not imminent and Brocade may not even go ahead with a sale. Oracle CEO Larry Ellison told investors at Oracle’s annual shareholder conference Wednesday. “We have no interest in buying Brocade,”  in response to a question from an investor according to Fortune.

brocadeTo compete with much bigger rival Cisco Systems Inc, the company has been bolstering sales partnerships with large technology vendors such as IBM and Dell Inc to expand their customer reach. In an interview with Reuters last month, Brocade Chief Executive Michael Klayko had said he did not see a need for Brocade to merge with or acquire another company, citing the company’s expertise and partnerships. However, “Interest in Brocade is picking up, and it is unlikely the company put itself up for sale in the absence of third-party interest,” according to Goldman Sachs analyst Min Park. “Brocade is a likely strategic fit for a number of potential acquirers.” At Fortune, Park includes Hewlett Packard, Juniper, Dell, IBM  and Oracle among those.

It is unlikely that Dell will purchase Brocade since Dell has Perot Systems to digest and a sales partnership with Brocade. Iuniper is not in the financial postion, but is the most need of the product. IBM is financailly cpable but the hardware business seems to be losing focus at Big Blue. That leaves HP  for three reasons, first it is financially capable, second it is looking to grow its ProCurve business and its EDS acquisition is well underway. The wild card could be Huawei, if they can get government approval. Of course, Brocade CEO Mike Klayko, just may have needed some extra pocket money as the Wall Street Journal article triggering a 14 percent jump in the company’s shares. Mr. Klayko’s $5 million in options increased by $700,000 in one day.
