Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.

Junkyard Gem: 1983 Jeep DJ-5L Mail Dispatcher

When it comes to putting mail in boxes, a simple and reliable vehicle works best. Say, a zero-frills steel box on wheels, with right-hand-drive, a fuel-efficient four-cylinder engine, no-hassle automatic transmission, sliding doors, and a big mail-sorting table instead of a passenger seat. That's what the AM General Mail Dispatcher DJ-5 was all about, and these bouncy little trucks were everywhere for decades. Here's a late-production example, still in USPS colors, spotted in a Denver-area self-service wrecking yard. Neither snow nor rain nor heat nor gloom of night stayed this courier from the swift completion of its appointed rounds. Note the "Sonic Eagle" USPS logos on the doors; this became the official USPS logo in 1993, nearly a decade after the final Jeep DJ-5s were built. Plenty of these trucks stayed in service into our current century, and a few are still being used by private mail-delivery contractors in rural areas. During the American Motors era of Jeep DJ production (1970 through 1984), a bewildering assortment of engines went into postal Jeeps. This is a 2.5-liter GM Iron Duke four-cylinder; before that, DJ-5s came with Audi power (more or less the same engine used in the Porsche 924, in fact), AMC straight-sixes, and Chevy Nova four-cylinders. The 1984 DJ-5Ms ran the AMC 2.5-liter four-cylinder. The earliest DJs were equipped with three-speed manual transmissions, but the American Motors-built postal-delivery versions all had automatic transmissions. This one has a three-speed Chrysler Torqueflite A904, a weird engine/transmission combination that should help you stump your friends during car-trivia debates. Check out the ultra-bare-bones heater/ventilation controls! These trucks were badged as AM Generals, not Jeeps (I couldn't find a single Jeep label anywhere on this one), just like the original HMMWV. However, you'd have to be a real hair-splitter to refer to this as an AM General DJ-5 instead of just Mail Jeep or Jeep DJ-5. Next time you complain about your subcompact rental car lacking driver-comfort features, consider this vehicle. I had a few high-school friends who owned DJ-5s, back in the early 1980s when they were available for a couple hundred bucks at government-surplus auctions. The first thing civilian DJ-5 owners always did was tear out the mail-sorting table and replace it with a random junkyard bucket seat (or an aluminum lawn chair). These trucks were very noisy, very bouncy, and very slow, but they always ran.

Watch the 2018 Jeep Grand Cherokee Hellcat blast off

It's all but official. Jeep will produce a Hellcat version of the Grand Cherokee with crazy horsepower. We mean crazy. Today, our spy shooters have captured video footage of this demonic creation. It's pretty short, but you can see a dark Grand Cherokee launch with vigor and then brake hard to a halt. We think we detect the whine of a supercharger amid the commotion. Jeep boss Mike Manley has said on video that the JGC Hellcat will arrive before the end of next year. Specs aren't known, but it seems likely that the Jeep Hellcat will share the blown 6.2-liter V8 used in the Charger and Challenger Hellcats. We've also heard rumors the Trackhawk name could be used for this vehicle. In those applications, the beastly Hemi pumps out 707 manic horsepower. Really, why wouldn't you do this? Jeep sales surged 22 percent around the world last year to 1.2 million, the brand's best year ever. Clearly, Jeep decided it was time to add an extreme performance vehicle. Jeep already sells an SRT model that pumps out 475 hp, so adding a top-end Hellcat seems logical. And a Hell of a lot of fun. Related Video:
