Uber Security (Keys on Github)

As information-driven physical-world services like Uber, AirBnB and Square become more common they bring up some unique security issues for the interacting parties. To make the service effective they collect and store a large amount of user data. This data can be compromised as data needs to be shared not only with users but also with third party apps.  Then there is a threat of physical assault, physical damage and stolen card data.

At minimum, it is imperative to have a comprehensive information security program that protects the core data collection/processing pipeline and extends outwards to a) services built on top of the data and b) physical identities of the parties involved to assure them of trust in a brief interaction enabled by the information.

This article discusses how 50,000 driver information were compromised at Uber. The driver database keys were found on github ? How is that possible ?

If it is possible then it is a security incident that needs visibility, not just into the information within an enterprise but also outside it. The security incident and event monitoring products that exist (e.g. ArcSight, Bit9, CrowdStrike, Tanium) barely scratch the surface of this requirement – the haystack is bigger than we think it is and the needle we don’t know in advance.

The physical security is harder to deal with. One thing becomes apparent is that the reason the supply of hotels, cabs, even credit card issuers was constrained was due to legislation and regulations that were designed to create a high bar for an offering and build a high level of trust between the interacting parties.

Those lines are being redrawn with technology. The people impacted by the technology should be part of the conversation in coming up with appropriate ways to regulate the offerings to maintain security and safety.

Biometric User Identification for IOT

Two-Factor authentication solutions are based on the premise that the combined verification of (i) a thing possessed (a card) and (ii) a piece of information known to the user (a pin or password) provides a high degree of assurance to authenticate users. For financial and enterprise transactions it gives a high level of security. But 2FA is not a seamless solution – as the number and variety of services and devices for a user increases – it requires the user to carry a number of cards/tokens/devices and remember several passwords (that are unique, complex, updated). It is also not a foolproof solution as the identity theft continues to be a problem.

With the large number of IOT applications and devices appearing, the problem will become worse. Consider a health monitoring device that needs to periodically share information of a patient with her family members and doctor, while keeping the information safe from cloud attacks. Or consider keyless entry to vehicles or homes. For such common use cases entering complex passwords would be cumbersome.

With biometric authentication methods, as present with fingerprint based authentication on Apple and Samsung phones, there is a more direct identification of the user. But the way this is commonly used is not to eliminate passwords completely – it is typically used to

  1. store existing passwords securely,
  2. reduce repeated password entry by extending session created by an existing password
  3. combined with a user identifier such as a phone number or email address
  4. combined with a password (e.g. for byod deployments where multiple users can register fingerprints)

One can imagine a two factor auth where both factors are biometric, such as multiple fingerprints, or fingerprint and iris authentication. Such a two factor biometric approach could eliminate the need to remember passwords and reduce friction in accessing services securely. An example is the combination of facial recognition and fingerprint recognition.

Biometric authentication methods being worked on include gait recognition and voice biometrics. These can be included in a continuous authentication method.

SecureAuth and BehavioSec Auth Presentation, Palo Alto

IDC gave a good security landscape overview at the SecureAuth executive luncheon today in Palo Alto.

SecureAuth provides a flexible adaptive authentication system that balances security with user experience.

BehavioSec does biometric authentication based on user behavior such as the pattern of keystrokes when entering a password. It builds a statistical profile and them determines if the password is entered anomalously. It provides collector SDKs to collect this information from mobile apps and websites.

In case of a large difference between the expected pattern and the current pattern, the SecureAuth integration forces a step up auth to a second factor.

There is adoption of this kind of technology in banking, retail and other verticals.

Integrate Conference 2015

This conference has a focus on integration between technologies and is held with API World. A dominant theme was connected cars.

ActiveScaler demonstrated its Connected Car platform and API that delivers five types of information. It had a great session with visits from a number of car companies, partners, vendors advisors, investors and interested public.

The highlight was a visit by Maria Roat, CTO, US Department of Transportation where she and her colleague shared their views on the evolution of transportation technologies with ActiveScaler team.

ActiveScaler demonstrated an app that connects the car to the cloud to provide rich vehicle and driver analytics in real time.

Salesforce Dreamforce Conference

At the Salesforce conference were several interesting IOT demonstrations.

One of them could Docker to be run inside a Raspberry Pi. This can be used for seamless OTA upgrade of IOT software. Another allowed instant analysis of the chemical composition of a drug and the information is connected to an app.

Another interesting demo was Built.io, which is like an IFTTT for different apis and IOT flows – a virtual circuit diagram allows inputs to be cascaded together in a flexible manner to achieve a variety of outcomes.

Salesforce made the announcement of the IOT Cloud which is built on Salesforce Thunder, a massively scalable real-time event-processing engine. Business can create alerts or filters to identity important data from event streams. This can be used to send alerts from manufacturers to customers or customers to manufacturers, for instance for a malfunctioning device or for a car recall.

Marc Benioff – “The Salesforce IOT Cloud will empower businesses to build proactive 1:1 relationships with their customers to deliver a new kind of customer success”.

Here’s a review of this announcement with the opinion that it is currently more of a positioning statement than a real capability – http://www.zdnet.com/article/dreamforce-2015-salesforce-thunder-unavailable-2016/

CAN bus attacks

A CAN is a Controller Area Network. Electronic Control Units (ECUs) are networked together in a car using a bus based on the CAN standard. A car will have one more CAN buses which are typically accessible via the Onboard Diagnostics (OBD II) port.

The CAN allows a distributed network of micro-controllers and devices to do real time messaging with each other with CAN packets, to exercise real time control. It is used in industrial control systems, vechicles such as airplanes and ships, and automotive systems.

ECU examples are Airbag, HVAC, ABS and Engine Control Unit.

A podcast interview with Chris Valasek: https://securityledger.com/2015/07/podcast-interview-with-car-hacker-chris-valasek-of-ioactive/

Most cars do allow CAN access via OBD. Tesla does not, but the CAN information is still accessible via another port.

It may sound unusual that the OBD port meant for diagnostics should allow sending commands to the CAN bus, but this is in fact possible, in part because there is no source identifier or authentication build into CAN packets.

What if an ECU itself has some kind of problem or degradation ? This can increase vulnerability when combined with open CAN bus access.

For example, there were two independent recalls in early 2015 related to defective airbag deployments. The Jeep recall was due to software that detected rollover aggressively and deployed the airbags. The NHTSA recall was due to Takata airbags with faulty inflators.

As we bravely head to an IOT world where various devices and controllers are networked to external entities, such concerns will increase.

There are attacks on other car interfaces such as bluetooth, telematics unit and remote key. Recently (July) there was an attack on Jeep which caused an update to fix the bug. The Israeli media reported a couple startups, Argus and TowerSec could have prevented this attack.   Update Jan 2016: TowerSec is acquired by Harman – CES 2016 announcement.

OpenDNS and Cisco

Cisco recently acquired OpenDNS and its security offerings.

The Domain Name Service is a hierarchical lookup service that converts human readable names to IP addresses that are used for routing. As such the DNS lookup servers can see the names being accessed, their access trends, web security attack patterns such as phishing redirects and so on.

But how did OpenDNS come to focus on security ? It was preceded by a free DNS service called EveryDNS started by David Ulevitch in his college dorm in 2001. The free nature of it attracted an interesting clientele– a number of malicious services, sites and agents.  This gave EveryDNS visibility into this part of the internet – both the customer view and a real-time view. David realized the potential and started a new company OpenDNS with both a free+paid dns offering and a growing number of security services.

In 2012 OpenDNS offered an Umbrella service to blacklist malicious sites. The most interesting offering is its OpenDNS Security Graph. The Umbrella Security Graph maintains and automatically updates malware, botnet, phishing domain and IP blacklists. This is then sold to enterprises – a higher margin business than providing DNS lookup alone.

Verisign is also in the DNS security business after it sold its certificate business to Symantec.

Tesla Model S hacked by researchers

Tesla is an advanced computer on wheels. How is security for such systems designed ? Snippets from below are insightful.

http://www.wired.com/2015/08/researchers-hacked-model-s-teslas-already/

“Two researchers have found that they could plug their laptop into a network cable behind a Model S’ driver’s-side dashboard, start the car with a software command, and drive it. They could also plant a remote-access Trojan on the Model S’ network while they had physical access, then later remotely cut its engine while someone else was driving.”

“Tesla distributed a patch to every Model S on the road on Wednesday. Unlike Fiat Chrysler, which recently had to issue a recall for 1.4 million cars and mail updates to users on a USB stick to fix vulnerabilities found in its cars, Tesla has the ability to quickly and remotely deliver software updates to its vehicles. Car owners only have to click “yes” when they see a prompt asking if they want to install the upgrade.”

“The Model S has a 17-inch touchscreen that has two critical computer systems. One is an Ubuntu server responsible for driving the screen and running the browser; the other is a gateway system that talks to the car. The Tesla gateway and car interact through a vehicle API so that when a driver uses the touchscreen to change the car’s suspension, lock the doors, or engage its parking brake, the touchscreen communicates with the gateway through an API, and the gateway communicates with the car. The touchscreen never communicates directly with the car. “At least so our research has found so far,” Mahaffey says.”

“The Model S has an Ethernet cable for diagnostic purposes and by connecting to this they were able to get access to the car’s LAN. This allowed them to uncover information about the firmware update process, such as the configuration of the VPN the car used to obtain updates as well as the URLs from where the updates were downloaded. They also found four SD cards inside the car that contained keys for the VPN structure, and they found unsecured passwords in an update file that allowed them to gain access to the Tesla firmware update server. “By using the VPN credentials we got from the SD card, we were able to configure and open VPN clients to go and talk to Tesla’s infrastructure and mimic the car.”

Even though Tesla provided the update quickly, having unsecured passwords in a file that allowed access to go to the firmware update server should alert one to the risks of connected cars.

Zigbee Scanning from a Flying Drone

From http://thehackernews.com/2015/08/hacking-internet-of-things-drone.html

Security researchers have developed a Flying Drone with a custom-made tracking tool capable of sniffing out data from the devices connected to the Internet – better known as the Internet-of-things.

Under its Internet of Things Map Project, a team of security researchers at the Texas-based firm Praetorian wanted to create a searchable database that will be the Shodan search engine for SCADA devices.

 

The researchers located all ZigBee-enabled smart devices and networks and then started expanding their research.
“When [IoT devices] communicated over a wireless protocol called ZigBee, this protocol is open at a network level. So when the devices start connecting, they send out beacon requests. We capture data based on this,” says Paul West Jauregui, from Praetorian.
ZigBee is a popular smart-home wireless communication standard used by the majority of Internet of Things (IoT) devices today.
ZigBee protocol, which lets IoT devices talk to each other, is implemented by major vendors including Toshiba, Philips, Huawei, Sony, Siemens, Samsung, Motorola, and many more.

Building Automation Security Plan (Target, HVAC)

The Target data breach in 2013 affected 40million credit cards. It was traced back to an onsite HVAC (that was remotely accessible for billing) being on the same network as the rest of the system . The credentials for the HVAC were breached and used to attack the internal computers.

The link below discusses a comprehensive security plan for a building automation system. The connected components are identified and the network and systems are designed for authorized access.

http://www.automatedbuildings.com/news/may14/articles/llnl/140425010101llnl.html

One can see such a plan being useful for a number of sensor/IOT systems – e.g. energy, temperature and and video sensors.

OS X Malware and Connected homes

Here is a talk from Synack on OS X malware. iOS is locked down but OS X is much more open – obviously one can download applications outside the appstore and load and run apps and dylibs that are unsigned. This impacts security for a connected home with many devices with hubs that may be OSX based.

For example here’s a description of remote control of a baby monitor – http://www.zdnet.com/article/iot-security-under-scrutiny-as-apple-looks-at-smart-home-system/ .
