Online Security in Era of Connected Cars

Online Security in Era of Connected CarsKarl-Thomas Neumann, CEO of General Motors (GM) European Opel brand announced that GM would launch OnStar telematics service in vehicles sold in Europe in late 2015. The Opel CEO declared the new technology, “transforms the car into a true part of the Internet of things.” The Detroit Bureau says it raises some of the same concerns consumers face on the Internet, including how to protect their privacy in highly connected cars.

App controlled carEven though a growing number of consumers have embraced the idea of having mobile access to smartphone apps, built-in Wi-Fi, and the safety and security promised by systems like OnStar issues loom that consumers, manufacturers, and regulators need to address. At the 2014 Consumer Electronics Show, Jim Farley,  then the top marketing executive at Ford Motor Company (F),  told an audience that the automaker “know(s) everyone who breaks the law, we know when you’re doing it,” thanks to the data collected by its OnBoard Sync technology system.

Despite a quick backtrack by Mr. Farley, the article says he was being truthful. The fact is, the onboard black boxes in most cars are now equipped with two-way capabilities. Privacy has become “a big issue,” according to Jon Allen, a principal with consulting firm Booz Allen Hamilton who focuses on security issues. Precisely what makes such technology so compelling is why it is also so worrisome. Mr. Allen told The Detroit Bureau,

Connected products provide customization and convenience because of the data they track. Part of the great opportunity to improve the customer experience is producing a vehicle that ‘learns’ your habits and preferences. But that information must be protected.

Data privacyThe EU takes privacy seriously and these types of tracking technology have drawn the attention of regulators in Europe and to a lesser extent, in the U.S. The article describes a measure of just how strongly Europeans feel about the issue that came during Opel chief Neumann’s news conference. Unlike the U.S. version of OnStar, the European system will include a “Privacy” button to let a user “choose whether they want to provide location information or not.”

That choice would only be over-ridden after a crash severe enough to trigger OnStar’s emergency call system, CEO Neumann explained. It’s designed to call rescue crews in the event of an accident severe enough passengers might be disabled.

Don't panicThere have been experiments with marketing that could target motorists much as Google today can toss ads at a web viewer based on information revealed by hidden “cookies.” Imagine, they suggest, being able to send a McDonald’s ad and virtual coupon to a car driving near one of its restaurants around lunchtime.

While some drivers might embrace that possibility, others are appalled. The Detroit Bureau reports the potential to reveal more detailed personal information, as well as allowing a vehicle to be tracked, is raising flags on both sides of the Atlantic.

Digtal trackingIn the U.S., an auto industry alliance recently agreed on an approach called “Privacy Principles for Vehicle Technologies and Services.” (rb- Which I covered here) Meanwhile, both the U.S. Federal Trade Commission and the National Highway Traffic Safety Administration are exploring the issues – though in some cases, they are actually encouraging greater access, noted analyst Allen.

The issue is further complicated by the threat of cyber-criminals exploiting vulnerabilities in-vehicle communications systems.

I first covered this threat in 2011 here and here. And the theoretical became real in 2015 when researchers demonstrated they could use online systems to take over a Jeep Grand Cherokee.

The threat to personal freedom and privacy in your car has accelerated as Apple (AAPL) and Google (GOOG) join Microsoft (MSFT) in the battle to rule the car. Apple’s automotive ambition does not stop at CarPlay, they are also focused on developing an iCar. Google’s Autonomous Cars ambitions are well known, but their efforts to take over the car cockpit are also taking off with Android Auto.

The government is contributing to the connected car conundrum. The Feds are abetting the Autos by trying to prevent security researchers from doing testing and reverse engineering that could improve security and safety for all of us according to Naked Security.

Back to School Cybersafety Resources

Back to School Cybersafety ResourcesThe new school year is here. If cybersafety is not on your “back to school” checklist, it should be. SecureWorld offered up a list of resources to help parents have a meaningful conversation about “cyber-safety” with their children. Parents need to talk with their kids about what they can do to protect themselves from the threats that are lurking online.

There are a variety of resources available that can help parents teach their children about the importance of Internet safety and privacy. Here are some recommended in the article.

threats lurking onlineIn 2009, President Obama asked the Department of Homeland Security to create the Stop.Think.Connect. Campaign to help Americans understand the dangers that come with being online. The program stresses that cybersecurity is a shared responsibility. Parents can download a Cybersecurity for Kids tip card (PDF) that offers helpful hints and advice designed specifically for children.

ConnectSafely.org is a nonprofit organization dedicated to educating users of connected technology about safety, privacy and security. The website offers a number of Parent Guides, written by parents for parents, including:

Back to school

The National Cybersecurity Alliance is an industry-led group, founded by the likes of Symantec (SYMC), Cisco (CSCO), Microsoft (MSFT), and EMC (EMC), whose mission is to educate and therefore empower a digital society to use (rb- their products) the Internet safely and securely at home, work and school.

Parents and teachers can download tips and resources from their website StaySafeOnline.org. The tip sheets are created specifically for different age groups ranging from kindergarten to college students. This site offers resources like:

Free Security Check-Up and Tools – Which has download locations for tools from A to W – Avast to Webroot. (as always use at your own risk).

Tip Sheets for:

The author states that industry professionals are also placing a high priority on preparing children for life in cyberspace. For instance, the (ISC)2 Foundation’s Safe and Secure Online program was introduced in 2006 in conjunction with Childnet International. They offer resources for parents which include Top 10 Tips for Parents (PDF) and the Parent-Child Commitment to Safety Agreement (PDF).

The Business Insider polled and a bunch of industry cyber security experts about what they teach their kids about the internet. The experts working in the field recommend you:

  • Start discussing online safety at an early age.
  • If you wouldn’t do it face to face – Don’t do it online.
  • Once you’ve written something you can’t delete it.
  • Not just to tell them the rules but also to spend the time/

Mobile Apps Leaking Your Info

Mobile Apps Leaking Your InfoJust in time for Blackhat, San Francisco-based Appthority released its Q2 2015 Enterprise Mobile Threat Report. The big headline from the Appthority report is that enterprise mobile apps are leaking your info. They are sending personally identifiable information (PII) and other sensitive information all over the world often without the enterprise’s knowledge. Your phone is leaking your info all over the web.

Appthority logoFierceMobileIT says that the Appthority Enterprise Mobile Threat Team (EMTT) collected and analyzed security and risky behaviors in three million apps. They found that the top iOS apps sent data to 92 different countries, while the top Android apps are leaking your info to 63 different countries.

Zombie apps are leaking your info

The report found another threat to all data. Appthority’s all-in-one App Risk Management service shows that 100% of enterprises surveyed have zombie apps in their environments. Zombie apps are apps that have been revoked by the app stores and are no longer getting security updates. Zombie apps can give attackers a conduit into the enterprise.

zombie appsThe report estimates that 5.2% of the Apple (AAPL) iOS apps on employee devices in an enterprise are dead apps, and 37.3% are stale Apps. On Google (GOOG) Android devices, 3.9% are dead apps and 31.8% are stale apps.

Zombie apps can leak your info. Appthority explains that malicious third parties could use a man-in-the-middle attack to hijack the update mechanism for these apps to install new malware on user devices.

Threat to the enterprise

Despite the threats, app stores run by Apple, Google, and Microsoft (MSFT) are under no regulatory obligation to tell users of revoked apps anything after release. Including copyright infringements or serious security/privacy concerns.  The report points out. Domingo Guerra, president, and co-founder of Appthority classified this as a stealthy risk; “The ongoing threat of zombie apps and stale apps continues to be an ‘under the radar’ threat to the enterprise.

programmersA third risk to the firm’s data comes from their own programmers according to the venture capital-backed Appthority. The firm says over-taxed enterprise app development teams are increasingly relying on third-party libraries and software development kits. Vulnerabilities in the third-party packages can put enterprise data at risk when they get baked into a corporate app.

The company told CSO that few mobile devices have security applications installed. In particular, only 4 percent of Android devices in use within enterprises had on-device scanning solutions.

Rb-
Firms that depend on mobile solutions as part of a Bring Your Own Device (BYOD) effort need to look after their apps as well as connectivity and hardware and data and governance and reimbursements. Bring your own device hardly seems like a cost saver to me.

I have said this repeatedly, it seems like costs are just being moved around. From spending on a PC in the office that is very less likely to be lost and that can be controlled to a bunch of new enterprise applications like EMM, mobile anti-malware to app monitoring.

Another Hole in Internet Armor

Another Hole in Internet ArmorAnother hole in our Internet armor has been discovered. The hole is in the Diffie-Hellman key exchange, a popular cryptographic algorithm that allows Internet protocols to agree on a shared key and negotiate a secure connection. It is fundamental to many protocols including HTTPS, SSH, IPsec, SMTPS, and protocols that rely on TLS.

Diffie-Hellman key exchangeResearchers from the University of Michigan, Inria, Microsoft Research, Johns Hopkins University, and the University of Pennsylvania have uncovered several weaknesses in how Diffie-Hellman key exchange has been deployed. In what they are calling the Logjam attack the DF flaw allows a man-in-the-middle attacker to downgrade vulnerable TLS connections to 512-bit export-grade cryptography. This allows the attacker to read and change any data passed over the connection.

The problem, according to the researchers, is that millions of HTTPS, SSH, and VPN servers all use the same prime numbers for Diffie-Hellman key exchange. Practitioners believed this was safe as long as new key exchange messages were generated for every connection. However, the first step in the number field sieve—the most efficient algorithm for breaking a Diffie-Hellman connection—is dependent only on this prime. After this first step, an attacker can quickly break individual connections.

prime numberTo prove this hypothesis, the researchers carried out this computation against the most common 512-bit prime number used for TLS and demonstrated that the Logjam attack can be used to downgrade connections to 80% of TLS servers supporting DHEEXPORT.

They also estimated that an academic team can break a 768-bit prime and that a nation-state can break a 1024-bit prime. Breaking the single, most common 1024-bit prime used by web servers would allow passive eavesdropping on connections to 18% of the Top 1 Million HTTPS domains. A second prime would allow passive decryption of connections to 66% of VPN servers and 26% of SSH servers.

VPN attackThere is speculation that this “flaw” was being exploited by nation-state bad actors. A close reading of published NSA leaks shows that the agency’s attacks on VPNs are consistent with having created, exploited, harnessed the Logjam vulnerability.

What should you do?

1 – Go to the researcher’s website https://weakdh.org/ to see if your browser is secure from the Logjam flaw. (It reported that Google Chrome Version 43.0.2357.81 (64-bit) on OSX 10.10.3 was not secure}

2 – Microsoft (MSFT) patched the Logjam flaw on May 12 with security bulletin MS15-055. A Microsoft spokesperson told eWEEK;

Customers who apply the update, or have automatic updates enabled, will be protected. We encourage all customers to apply the update to help stay protected.

3 – Google (GOOG) fixed the issue with the Chrome 42 update, which debuted on April 15. Google engineer Adam Langley wrote;

We disabled TLS False-Start with Diffie-Hellman (DHE) in Chrome 42, which has been the stable version for many weeks now.

patch for Firefox4 – Mozilla’s patch for Firefox isn’t out yet, but “we expect it to be published in the next few days,” Richard Barnes, cryptographic engineering manager at Mozilla, told eWEEK.

5 – DarkReading reports that on the server-side, organizations such as Apache, Oracle (ORCL), IBM (IBM), Cisco (CSCO), and various hosting providers have been informed of the issue. There has been no response from these tech titans.

The researchers have also provided guidance:

  1. If you have a web or mail server, they recommend  – disable support for export cipher suites and generate a unique 2048-bit Diffie-Hellman group. They have published a Guide to Deploying Diffie-Hellman for TLS with step-by-step instructions.
  2. If you use SSH, you should upgrade both your server and client installations to the most recent version of OpenSSH, which prefers the Elliptic-Curve Diffie-Hellman Key Exchange.
  3. If you’re a sysadmin or developer, make sure any TLS libraries you use are up-to-date, that servers you support use 2048-bit or larger primes, and that clients you maintain reject Diffie-Hellman primes smaller than 1024-bit.

Finally, get involved. Write someone, your representative, senator, your favorite bureaucrat, the president, your candidate, and tell them to get out of the way. 

Ars Technica notes that Logjam is partly caused by export restrictions put in place by the US government in the 1990s, to allow government agencies the ability to break the encryption used in other countries. “Logjam shows us once again why it’s a terrible idea to deliberately weaken cryptography, as the FBI and some in law enforcement are now calling for,” said Michigan’s J. Alex Halderman to the report. “Today that backdoor is wide open.”

Password Pain Continues

Password Pain ContinuesDespite claims to the contrary, the password isn’t dead yet. Help Net Security points out new research from SecureAuth that documents how dependent many firms are on passwords. In fact, the research found that 40% of IT decision-makers admit that passwords are their only IT security measure. The IT leaders also believe it will take 5 years to see a significant shift in organizations’ reliance on passwords. The author says this is a worrying revelation, considering how many security breaches are the result of compromised credentials.

The researchers found that the entertainment, hospitality, and leisure industry is taking the most risks with its data as 65% of respondents from this sector admit their organizations only use passwords as a security method. (rb- No wonder they keep getting hacked!)

The author claims that SeaureAuth found that 45% of public sector organizations only use passwords. (rb- Another reason to limit how much data they collect on citizens)

Despite companies relying on passwords alone, the survey revealed that 63% of respondents believe their current authentication methods are effectively protecting valuable assets. The survey also revealed that firms worry about protecting different resources:

  • 29% say protecting the company’s VPN is critical
  • 28% believe protecting on-premise applications is a top priority
  • 20% stated protecting Cloud and SaaS is the most important, and
  • 18% said mobile takes precedence.

Nick Mansour, Executive Vice President of Worldwide Sales at SecureAuth explained,

As the skills of hackers continue to evolve, organizations are going to have to wise up to new methods of information access security, such as adaptive authentication which can leverage real-time threat intelligence, biometrics and even behavioral analysis.

Windows 10 logoFrighteningly only 44% of SecureAuth respondents have plans to change or enhance their security model in the next two years. The forthcoming Microsoft Windows 10 can help firms evolve their authentication processes. Help Net Security reports that Windows 10, includes a new feature called Windows Hello. Windows Hello will allow users to authenticate themselves using biometrics. The SecureAuth study reports that only 28% of IT decision makers believe that businesses will biometrics in 5 years’ time.

The article reports that Microsoft (MSFT) considers Windows Hello authentication more secure than using passwords – so secure, in fact, that it can be used in government organizations, the defense, financial, and health care industry. Microsoft’s  Joe Belfiore wrote

Our system enables you to authenticate applications, enterprise content, and even certain online experiences without a password being stored on your device or in a network server at all

Facial recognitionMr. Belifore says Windows Hello will work with existing fingerprint readers. Windows Hello will also work with facial or iris detection by combining special hardware and software; “The cameras use infrared technology to identify your face or iris and can recognize you in a variety of lighting conditions.”

Mr. Belfiore also introduced Windows Passport, a programming system that can be used to provide a more secure way of letting you sign in to sites or apps. The article explains that unlike with passwords, with which you authenticate yourself to apps, sites, and networks, Passport allows Windows 10 to do that in your stead: again, without sending up a password to their servers. Mr. Belfiore says:

Windows 10 will ask you to verify that you have possession of your device before it authenticates on your behalf, with a PIN or Windows Hello on devices with biometric sensors. Once authenticated with ‘Passport’, you will be able to instantly access a growing set of websites and services across a range of industries

rb-

Couldn’t Redmond pick a name other than Passport? Reminds me of the Hotmail days.

There is of course the age-old problem of what to do if your biometric signature is stolen. You can easily change your iris with a sharp stick, but that does not seem very efficient.

What do you think?

Will Windows 10 biometrics take off?
