Overhung load adaptors provide load support and contamination protection

Overhung load adaptors (OHLA) provide both overhung radial and axial load support to protect electrified mobile equipment motors from heavy application loads, extending the lifetime of the motor and alleviating the cost of downtime both from maintenance costs and loss of production. They seal out dirt, grime, and other contaminants too. Zero-Max OHLAs are available in an extensive offering of standard models (including Extra-Duty options) for typical applications or customized designs.

Researchers find vulnerabilities in cars connected to smartphones

Many of today's automobiles leave the factory with secret passengers: prototype software features that are disabled but that can be unlocked by clever drivers.

In what is believed to be the first comprehensive security analysis of its kind, Damon McCoy, an assistant professor of computer science and engineering at the NYU Tandon School of Engineering, and a group of students at George Mason University found vulnerabilities in MirrorLink, a system of rules that allows vehicles to communicate with smartphones.

MirrorLink, created by the Connected Car Consortium, which represents 80 percent of the world's automakers, is the first and leading industry standard for connecting smartphones to in-vehicle infotainment (IVI) systems. However, some automakers disable it because they chose a different smartphone-to-IVI standard, or because the version of MirrorLink in their vehicles is a prototype that can be activated later.

Hardware setup in which an Android phone is integrated with the head unit of a 2015 model vehicle (upper left). MirrorLink is the connection protocol and allows the driver or passenger to control phone apps via the car's dash and steering wheel controls.

 

 

 

 

McCoy and his colleagues found that MirrorLink is relatively easy to enable, and when unlocked can allow hackers to use a linked smartphone as a stepping stone to control safety-critical components, such as the vehicle's anti-lock braking system. McCoy explained that "tuners" -- people or companies who customize automobiles -- might unwittingly enable hackers by unlocking insecure features.

"Tuners will root around for these kinds of prototypes, and if these systems are easy to unlock they will do it," he says. "And there are publicly available instructions describing how to unlock MirrorLink. Just one of several instructional videos on YouTube has gotten over 60,000 views."

The researchers used such publicly available instructions to unlock MirrorLink on the in-vehicle infotainment system in a 2015 vehicle they purchased from eBay for their experiments.

The automaker and supplier declined to release a security patch -- reflecting the fact that they never enabled MirrorLink. McCoy pointed out that this could leave drivers who enable MirrorLink out on a limb.

The authors hope their research, presented at the 10th USENIX Workshop on Offensive Technologies (WOOT '16) in Austin, TX, this past August, will raise the issue of drivers unlocking potentially insecure features before IVI protocols such as MirrorLink are even more widely deployed. Their paper is, "A Security Analysis of an In-Vehicle Infotainment and App Platform," by lead co-authors Sahar Mazloom and Mohammad Rezaeirad along with Aaron Hunter and McCoy. General Motors, the National Science Foundation, and the Department of Homeland Security provided funding.
